Beginning with Version 2.8, the default tag limit in wordpress is set to 45, witch is quite large and can definitely affect PageRank on small blogs with less PageRank to spread around. However the net affect can still be helpful on high authority blogs.

How to limit the number of keywords in WordPress tag cloud to control PageRank

The taxonomy parameter was added so that any taxonomy could be used as the basis of generating the cloud. That means that a cloud for Categories or any other Custom Taxonomies can be presented to visitors.

wp_tag_cloud( $args );

The $args variable is a simple array as follows:

$args = array(
'smallest' => 8,
'largest' => 22,
'unit' => 'pt',
'number' => 45,
'format' => 'flat',
'separator' => \\"\n\\",
'orderby' => 'name',
'order' => 'ASC',
'exclude' => null,
'include' => null,
'topic_count_text_callback' => default_topic_count_text,
'link' => 'view',
'taxonomy' => 'post_tag',
'echo' => true,
'child_of' => null
);

By default, the usage shows:

• smallest – The smallest tag (lowest count) is shown at size 8
• largest – The largest tag (highest count) is shown at size 22
• unit – Describes ‘pt’ (point) as the font-size unit for the smallest and largest values
• number – Displays at most 45 tags
• format – Displays the tags in flat (separated by whitespace) style
• separator – Displays whitespace between tags
• orderby – Order the tags by name
• order – Sort the tags in ASCENDING fashion
• exclude – Exclude no tags
• include – Include all tags
• topic_count_text_callback – Uses function default_topic_count_text
• link – view
• taxonomy – Use post tags for basis of cloud
• echo – echo the results

Another way to use is like in the next example:

wp_tag_cloud('smallest=15&largest=40&number=50&orderby=count');

So enjoy this and remember that maintaining a small outgoing links on your site maximize your webs site PageRank. And limiting the wordpress tag cloud can help a lot.

This is another simple function that does the trick:

//Register tag cloud filter callback
add_filter('widget_tag_cloud_args', 'tag_widget_limit');

//Limit number of tags inside widget
function tag_widget_limit($args){

//Check if taxonomy option inside widget is set to tags
if(isset($args['taxonomy']) && $args['taxonomy'] == 'post_tag'){
$args['number'] = 10; //Limit number of tags
}

return $args;
}

• File size and format (extensions and codecs)
• Browser and platform compatibility
• User internet connection (mobile vs desktop devices)
• Server resources (bandwidth, CPU, RAM)
• Privacy and data owning
• Content visibility and engagement

Therefore, depending on where you will insert the video and the application you use, you will be affected by some of the above or not. So let’s get our hands on it and do a step by step research about what is the simplest way to embed a video.

1. How to embed video into HTML website?

A video file can be embedded into a plain HTML page in various ways. Different HTML tags are/were used in different situations and they are all useful. So let’s take a look to the last arrived on the list.

1.1 Embed video using HTML5 video tag

Like I mentioned, in order to insert a video into your HTML page, you can use the newly introduced  <video> tag. The video tag was recently introduced into the HTML 5 recommendations.

<video width="320" height="240" controls>
    <source src="your_video.mp4" type="video/mp4">
    <source src=" your_video.ogg" type="video/ogg">
</video>

The video tag is really simple, and it works by automatically adding video controls attributes, like play, pause, and volume to the container. It is a good practice to include a width and height attribute. If this last 2 are not set, the browser will not know how much space to assign to the element and the video will make a jump/blink after the browser reads the file.

The source component lets you specify a video file to be loaded by the browser. The content between the <video>  and </video>  labels will be interpreted depending on the browser built-in codecs

You can then set simple attributes to customize your player. For example, if you want to start a video automatically on page load, use the autoplay attribute:

<video width="320" height="240" autoplay>
   <source src="movie.mp4" type="video/mp4">
   <source src="movie.ogg" type="video/ogg">
</video>

HTML5 video tag – Browser support

There are mainly tree video format that are used to cover all major browsers:

• Mp4 – MIME type video/mp4
• Webm – MIME type video/webm
• Ogg – MIME type video/ogg

By specifying the video file in all these formats you will have the best browser coverage possible.

A small incision here about the video tag and YouTube videos. You can use the HTML5 video tag to embed videos from YouTube to your website. Please note that this will not show the YouTube video preview so it is a smart thing to show an image/poster for this purpose.

<video controls="true" poster="/images/w3html5.gif">
    <source src="https://www.youtube.com/watch?v=3bGNuRtlqAQ" type="video/mp4" />
</video>

1.2 Embed video using HTML embed tag

The embed tag has been around for a long time thanks to the Netscape friends. Although it had a very good acceptation it was considered nonstandard and not included in the HTML 4 specification. It later becomes part of the new HTML5 standard and it seems to have a very good universal support.

<embed src="simple_video.mpeg" width="250"  height="180" autostart="false" />

As you can notice the embed tag does not require a closing tag. You can simply add your file to the source attribute and you are good to go. The embed tag was mainly used to include applications data and other media content. This are the main files that are supported by the embed tag.

• .mpeg – video content
• .wmv – video content
• .mov – video content
• .swf – application (could be video or any other type of content)

HTML embed tag – Browser support

Available attributes for the embed tag

There is a really long list of attributes that are supported by the embed tag. On the other hand, the only ones found in the HTML5 specifications are width, height, src, type and the global attributes (id, class, style, title etc)

Most attributes are not part of the HTML specification but are widely supported. Here are some of them that are useful when used with media files.

• autostart – sets if the media file will play on page load
• volume – set the volume when the media file starts playing. You can set the value from 0 to 100
• loop – sets whether the document will be replayed after it is done. Can have the genuine or false esteem.
• playcount – this sets up how frequently the document will be replayed. For instance playcount="2"  implies it will be replayed two times and after it will stop.

NOEMBED fallback for embed video files

Just in case there is someone who is browsing your website using Lynx browser or any other browser that does not have support for the embed tag, there is a fallback for them. You can use the  noembed tag like this.

<embed src="simple_video.mpeg" width="250"  height="180" autostart="false">
	<noembed>
		<a href="/transcripts/video_transcript.html">Transcript of "My favourite video"</a>
	</noembed>
</embed>

1.3 How to embed video files using the HTML object tag

Embedding multimedia files is not the main application for the object tag. Despite this, you can use it to insert videos into your HTML document.

<object  data="simple_video.mpeg" width="400" height="400">
	<param name="autoplay" value="true">
	<param name="volume" value="50">
</object>

You can set any other param that you need to control the file.

HTML object tag – Browser support

According to the HTML 5 recommendations, you should use video for video tag for files.

1.4 Use IFRAME to embed from third-party video platforms like YouTube or Vimeo

Another way to display a video in your HTML page is by using an iframe . Dedicated video content platforms like YouTube or Vimeo provide a simple iframe to display a video on your website.

Embed video from YouTube

<iframe "420" height="315" src="https://www.youtube.com/embed/yUtUHfwHI9I"></iframe>

To control the player, you will have to send some params via GET  in the URL as follows:

<iframe width="420" height="315" src="https://www.youtube.com/embed/yUtUHfwHI9I?autoplay=1"></iframe>

The list of available params can be found here: https://developers.google.com/youtube/player_parameters#Parameters

You can also found the option to dynamically generate the iframe on YouTube website:

• Click the ‘Share’ button below the video
• Click the ‘Embed’ button
• Copy full iframe  code that was given and paste it into the HTML.

If you did that you should get something similar to this:

<iframe width="560" height="315" src="https://www.youtube.com/embed/yGx0RJ3WzrA?rel=0&amp;controls=0&amp;showinfo=0" frameborder="0" allowfullscreen></iframe>

YouTube is providing, you with the iframe code for sharing purposes, but you can also display your video with the embed, object or video tag (although it is not recommended for long-term functionality).

Embed Video from Vimeo

Vimeo offers various ways to share his videos but still, if you click on their share button you will get a simple iframe like below:

<iframe src="https://player.vimeo.com/video/172794545" width="560" height="315" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>

Vimeo also offers the oEmbed API for embedding their video content. According to oembed.com, oEmbed is a format for allowing an embedded representation of a URL on third-party sites. You can find more about the oEmbed API documentation on Vimeo developer website here https://developer.vimeo.com/apis/oembed

HTML iframe TAG – BROWSER SUPPORT

1.5 embed vs object vs video vs iframe comparison

embed – it exists from almost the beginning of times, and it is quite very supported by all browsers but it has just been added to the HTML 5 specs. It doesn’t require a plugin to be specified for the embedded content; that’s up to the browser to figure out.

object – was added to HTML 4 as an alternative to embed  and it requires you to specify a plugin. Old Internet Explorer versions had really bad support for it. It is largely used for flash and other apps.

video – was added in the HTML5 specs and is quite well supported at this point. Browsers have codecs support built-in rather than relying on third-party plugins. Different browsers support different codecs so you will have to provide different file extensions if you want to be reached by all major browsers.

iframe – the iframe embed code is actually, a window to a remote page that contains your player with the loaded file. You have limited control over what is displayed.

What video embedding method should I choose?

It seems to be a general agreement that you should NOT use embed or object tags for this purpose. HTML5 has introduced a very specific tag for this and that is why you should use the video tag.

And this is where opinions split and everything really depends on your special case.

If you have a:

• good web server
• some programming skills
• reasonable understanding of what storing a big video file locally means
• you don’t care too much about bandwidth
• You don’t care that others can link to your files and take advantage of your bandwidth

…. then you can use the HTML 5 video tag and have complete control over your player, content statistics and much more.

If what you are looking for a way to publish a video and just forget about anything else go ahead and use iframes. YouTube, Vimeo, and many others have a solid experience in serving videos in the best way possible depending on the user browser, screen resolution, connectivity, and some other factors. So you will be ok.

What about iframe responsiveness?

As I said, an iframe is just a window to content stored on another website. This means that the browser can not know what width and height will have the content delivered in it unless you specify it. Smashing Magazine has a great article on this matter. Here is a small extraction of the solution:

The embed markup

<iframe src="https://player.vimeo.com/video/172794545" width="640" height="360" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>

.wrapper {
    position: relative;
    padding-bottom: 56.25%; /* 16:9 */
    padding-top: 25px;
    height: 0;
}
.wrapper iframe {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

2. How to embed video into a CMS site

CMS branch looks to be a little bit different when it comes to inserting videos. WordPress, Joomla, Drupal PrestaShop and others have all different ways to inserting a video into their content pages.

Some of them, WordPress, for example, have developed really good and user-friendly support for embedding videos.

2.1. Insert a video on a WordPress site

In our days to insert a video inside a WordPress post or page is really simple. There are mainly 2 ways of embedding a video in WordPress. You can either upload it and host it yourself or load it
from a third-party video platform like YouTube.

2.1.1. Upload video on WordPress site

The standard and native embed code for embedding a video stored locally would be similar to this:

[embed width="123" height="456"]http://yoursite.com/path_to_your/file.mp4[/embed]

Or like this:

[video src="/path_to_your/file.mp4"]

[video mp4="/path_to_your/file.mp4" ogv="/path_to_your/file.ogv" webm="/path_to_your/file.webm"]

I will start by saying that I (and everybody else) strongly discourage uploading video directly to WordPress or your personal hosting account. If you do a quick search you will find plenty of reasons about why this is not a good practice and why you should let this to YouTube, Vimeo, Amazon, or any other video dedicated service.

So, if you still want to go on and upload a video to WordPress you have to know that this is the default video file formats that you are allowed to upload:

If you would like to add your own extension you can do that by adding a filter. Let’s try to add the WebM video extension.

add_filter('mime_types', 'custom_upload_mimes');

function custom_upload_video_ext ( $actual_mimes=array() ) {

    $actual_mimes['webm'] = 'video/webm';

    return $actual_mimes;

}

You should add this to your function.php  inside your theme directory. Please note that in multi-site version you have a section under “MultiSite Dashboard > Settings > Network Settings”

There is also a plugin to add or edit allowed upload file extension under WordPress. You can do that with the WP Add Mime Types plugin.

Anyway, once done that you can step forward and actually upload the video inside your blog post. Go to your Add media button and upload the video file like you usually do with any image. You can also add a video to your Media Library, to be available for future usage.

Please note that in order to play the video files with the WordPress standard Video Player you will need to have them encoded with the MPEG-4 codec. This means that the file extension must be .mp4.

For other file extensions and codecs, you will have to do a small research and find a custom player.

2.1.2. Insert a video from YouTube, Vimeo, and others

From version 2.9 and on WordPress has incorporated automatic link detection. This means it will turn the URL into a native embed code and provide a preview in the WP visual editor. According to WordPress documentation:

To embed a video or another object into a post or page, place its URL into the content area. Make sure the URL is on its own line and not hyperlinked

Here is a simple example of how you should include a YouTube link in the WP visual editor.

Check here my favorite video on Youtube

https://www.youtube.com/watch?v=nrIPxlFzDi0

Rate it if you like it

This is the equivalent of using a shortcode like this:

YouTube is not the only one that admits automatic embed. The list is big and the WordPress guys are continually working to add new ones.

You can check here the full list of sites That WordPress will automatically detect and embed the object: https://codex.wordpress.org/Embeds

I would also like to mention that WordPress allows the use of oEmbed object format although it only attends to an internal whitelist of known sites. But if you know what you are doing you can add more to the list.

Here is an oEmbed example link request that will respond with a JSON formatted object.

https://vimeo.com/api/oembed.json?url=https%3A//vimeo.com/76979871

The oEmbed response will be similar to the following snippet:

{
    "type": "video",
    "version": "1.0",
    "provider_name": "Vimeo",
    "provider_url": "https:\/\/vimeo.com\/",
    "title": "The New Vimeo Player (You Know, For Videos)",
    "author_name": "Vimeo Staff",
    "author_url": "https:\/\/vimeo.com\/staff",
    "is_plus": "0",
    "html": "<iframe src=\"https:\/\/player.vimeo.com\/video\/76979871\" width=\"480\" height=\"270\" frameborder=\"0\" title=\"The New Vimeo Player (You Know, For Videos)\" webkitallowfullscreen mozallowfullscreen allowfullscreen><\/iframe>",
    "width": 480,
    "height": 270,
    "duration": 62,
    "description": "It may look (mostly) the same on the surface, but under the hood, we totally rebuilt our player. Here\u2019s a quick rundown of some of the coolest new features:\n\n\u2022 Lightning-fast playback\n\u2022 Redesigned Share screen\n\u2022 Closed caption and subtitle compatible\n\u2022 HTML5 by default\n\u2022 Purchase-from-player functionality for embedded Vimeo On Demand trailers\n\u2022 More responsive than ever (go ahead, resize it, we dare you!!!)\n\nWe\u2019re really proud of these updates. So proud that we made a spiffy new page to showcase all the reasons why we have the best video player in the galaxy. Check it out here: http:\/\/vimeo.com\/player\n\nIn short, this is a player that even haters can love.",
    "thumbnail_url": "https:\/\/i.vimeocdn.com\/video\/452001751_295x166.webp",
    "thumbnail_width": 295,
    "thumbnail_height": 166,
    "thumbnail_url_with_play_button": "https:\/\/i.vimeocdn.com\/filter\/overlay?src0=https%3A%2F%2Fi.vimeocdn.com%2Fvideo%2F452001751_295x166.webp&src1=http%3A%2F%2Ff.vimeocdn.com%2Fp%2Fimages%2Fcrawler_play.png",

    "video_id": 76979871,
    "uri": "\/videos\/76979871"
}

2.1.3. Use build-in functionality vs plugins

Well, this really depends on what are you expecting. If you are a light user of the video content and you will need to include a video into your posts from time to time, you should probably be ok with using the built-in functionality.

But if you are a heavy user of the video content and you want to insert daily video and build a gallery and have playlists, cache screenshots of the video and maybe scrap some snippets from the video descriptions you will probably need a plugin for that. There are lots of them in the WordPress plugin directory depending on your needs and you can start your search there. I will include a review of some of them in a future tutorial and link it from here, so make sure you bookmark it so you can come back later.

2.2. Insert video into Joomla and Drupal site

There is really more beyond WordPress. Joomla is really popular and Drupal is here to stay. So I will also drop a line or two about them.

To insert a video into a Joomla site you will first have to enable it from the editor customization. By default Joomla’s editor strips out tags like iframe and others. Go Plugin Manager and find your editor config, remove iframe from the prohibited tag and save your settings. On the other hand, depending on your version or your user role, Joomla may also filter the iframe tag. Go to Global Configuration and search for Text filters. Select No filtering and you should be good to go.

Finally, you will then embed the video the same as you would normally do. Just copy-paste the standard embed code from the YouTube page. After copying the embed code, go to your article and click your Source Code button. Paste it there and check your preview. Congratulations…you have just inserted your first video into Joomla.

How about Drupal? Can we insert a video into Drupal? If you are using Drupal you probably are used to installing modules. There are few modules on the Drupal website that are meant to help you to Insert a video file into your content page. Video Embed Field is a Drupal module that creates a simple field type that allows you to embed videos from YouTube and Vimeo and show their thumbnail previews simply by entering the video’s URL.

3. How to embed video in email

Video content is one of the best marketing tool out there, so why no use it in your email campaigns? Well, there is a simple reason for that. The email will be blocked before even being opened by your customer. Most (not to say all) email software or platforms are not allowing scripting, embeds, and iframes inside the email body. So your email will be filtered by the anti-spam filter and never arrive at his destination.

Although is not perfect, there is a workaround for this. Marketers recommend you place a picture of the video inside your email newsletter and link it to the real video. Your customer will have to click on the image of the video to be redirected to the page where you have your video embedded with an autoplay option enabled. This way, the user will only have to click once to see the video. Please note that most mobile devices will not allow the autoplay option and the user will have to tap again, but you will not have this problem on desktop devices.

Another way of doing something similar is to insert an animated GIF image like below.

You would be surprised what a good designer can do. Also, take into consideration that animated GIF images are not always small in size.

On the other hand, there is some exception to this rule. Gmail, for example, use auto-detection for YouTube videos. So just by copy-pasting the video URL Gmail will transform it into a video player on destination and place it just above the email body.

4. How to embed videos in presentations

How about documents like presentations. Presentations are (should be) very visual, dynamic and interactive. So inserting a video content inside a PowerPoint presentation or Google0-slide worth a try.

4.1. Add video inside Microsoft PowerPoint docs

PowerPoint allows you to embed a video from your PC directly inside the document. You can also embed a video from YouTube. Booth this will only work on PowerPoint 2010, 2013, 2016 o later versions. So make sure you have updated to the latest.

To embed a video go to Insert / Video / Video on my PC. That’s about it. After the video is loaded, you can start to configure options like size, autoplay, and few more details.

To embed a video from YouTube (At this moment YouTube is the only supported website), first you have to get the embed code from the YouTube page. Go to Insert / Online Video. Paste your code and start configuring playback options.

Another option, if you are using old versions of PowerPoint (like 2007) your only option is to include a simple link to the video.

4.2. Add video inside Google Slides presentation

If you are using Google Slides you are in good hands. YouTube videos are natively supported and you can even search them from inside the presentation.Just go to the Insert menu, select video and search for your favorite video to insert into your Google Slides presentation.

How about using a simple video file that is not hosted on YouTube. You can do a simple hack just like for email marketing campaigns. You can make a screenshot of the video and insert it in place. Upload the .mp4 file to your Google Drive and link it to the image. With a simple click, you will redirect the user to your video file.

5. How to use Dropbox to embed videos

Dropbox is not meant to be used for this purpose. Not too long ago some were using it as a CDN to save their server’s bandwidth and resources. Dropbox was forced to change its policies and apply some restrictions, especially on free accounts. So if you need a long-term solution for streaming your video content, do not use Dropbox for hosting them.

5.1. Use Dropbox as a video provider

If you still insist in hosting the video on Dropbox and publish it on your website, you can use the HTML5 video tag for doing that.

<video width="512" height="288" controls="controls">
<source src="https://www.dropbox.com/s/os60r63ogwfl408/your_video_here.mp4" type="video/mp4" />
</video>

Remember that according to Dropbox support, public links for free accounts may not use more than 10GB of bandwidth per day while that limit is 250GB per day for paid Dropbox accounts. The links are automatically suspended if any of your files exceed that limit.

5.2. Add video to Dropbox Paper

Don’t know about you, but I am a big fan of Dropbox Paper. So I wanted to test it against embedding a simple video and see how it responds.

There are mainly the same 2 ways to add a video to Dropbox Paper. Add it from your computer using drag and drop directly into the document or by copying the URL of the media file. Currently Dropbox Paper have native recognition for his own Dropbox files, YouTube, Vimeo, Facebook and Google Drive among others

6. How to embed a video in Social Networks

Inserting video to social media networks is probably the easiest thing these days. You just have to upload your video from your local drive and you are good to go. Big Social Networks like Facebook, Google+ Twitter, and others have native detection for YouTube, Vimeo, and other video platforms. So you don’t have to worry about it.

Facebook, for example, offers the other way around. You can upload your video to his servers and then embed it into your website. Please note that if you want to embed a video from Facebook you must set the visibility to as public.

7. Conclusion: Why use third-party platforms for embedding videos is better than self-hosted video ones?

In conclusion, I will try to be as short as possible resuming the pros and cons of hosting your own videos when embedding vs uploading to YouTube, Vimeo or any others to spread your video content.

7.1 Self-hosted videos pros and cons

Pros: Although there are not too many good and strong arguments, there are some to take into consideration.

• Your data is yours – This can be very important if you care about privacy and especially about brand development.
• More traffic for you – Because the video is hosted only on your site, if a person wants to watch that video will have to visit you.
• More shares of your website – If somebody likes your video it is possible that it will share your site and not your YouTube.
• Full control over your design – What you build is what you have. If you are a good developer you can build a great player that looks professional and there will be no third-party watermark on it.
• Your visitors will remain on your site when the video ends – It is very easy to be distracted with other content when viewing videos on YouTube for example.
• Your video will be ads-free – NO ads will be shown to your user before or after the video. Or at least you can control and decide it and provide your own ads.

Cons: Here are the bad guys of self-hosted videos. And there are quite strong.

• A lot of bandwidth – Hosting videos yourself can cause you a lot of server bandwidth usage.
• Big file size – You can quickly fill your server storage.
• Slow loading – Streaming video by several users can use lots of server CPU and RAM. This can cause slow loading and make the video to freeze.
• File compatibility – You will have to convert your video to various formats if you plan to rich all your users.
• Player compatibility – Finding the perfect video player that will perform ok in most browsers, resolutions, devices, and platforms can be quite tricky.
• Connectivity speed – Playing the video file depending on your user connection is another matter. You may want to serve a 1080p HD video to a high-speed Internet connection and maybe a 240p version to a 3G mobile device.
• Loss of traffic – You can easily loss some extra visits from a social network like YouTube.

7.2 Third-party video hosting pros and cons

Pros: Hosting your video on another website will give about the opposite. You will louse control in benefit of speed and performance

• 0 bandwidth cost for you – No bandwidth is used from your server.
• Multiple file formats – Your file is automatically converted in multiple file formats and loaded depending of the user requirements to provide full compatibility
• Multiple file size – User will be served a different file size depending of his Internet speed connection.
• Friendly user interface – You will use a well-known player for all your users.
• Social shares – You video can go viral on social networks in no-time.
• Privacy – Some platforms allow you to post private content.

Cons: And finally some not-to-good things about video hosting

• Bandwidth can cost you extra – Although 0 bandwidth sounds great, some platforms can cost you extra for more traffic.
• Annoying ads – Sometimes users are blown-up with ads at the beginning, in the middle of after the video ends.
• Privacy – You do not always own your content and that can be a big pain in the ass.
• Content spread – You do not have full control over how the player looks like and where your content is re-posted
• Easy distraction – It is quite easy for your visitor to go with a funny videos about cats instead of continue visiting your site.

And this is about all about the different ways to embed videos. Hope it is useful to you. Please let me know your opinions about where you host your video sand why.

If you remove the Toolbar, then you are effectively removing the Dashboard Header, which is something the folks at WordPress don’t think you should be doing.

Is it Impossible to Remove the Toolbar?

The toolbar, where the Admin Bar was in old versions, contains vital links for you to log-out, and the links to go back to the main site. It CANNOT be disabled, and has no hooks to be disabled it. Besides if you are using Multisite, all the network admin links are in there.

On the other hand you CAN however turn it off on the front end in your profile. Remember this is only for your profile.

If you would like to accomplish the same thing for all your users (remember this is just for the front end toolbar) you can place the following into your functions.php file.

function remove_admin_tolbar_on_frontend() {
	remove_action('wp_head', '_admin_bar_bump_cb');
}
add_action('get_header', 'remove_admin_tolbar_on_frontend');

There are also tons of plugins that can help you a hide the toolbar. You can get one from here: https://wordpress.org/plugins/search.php?type=term&q=remove+admin+bar

Some are using the same practice explained here and some are only hiding it using css. Note that if you are using CSS the admin toolbar is still loaded but not displayed to the user.

You will have to go to the wp_options table and search for a specific value in the option_name column. Please note that the table prefix ( wp ) is the standard prefix but can be different from one installation to another.

You have to search for active_plugins , so after selecting the option table, go to your Search tab to do that.

You can also run the next SQL sentence to search for the active_plugins key

SELECT * FROM `wp_options` WHERE `option_name` LIKE 'active_plugins'

To deactivate or disable all plugins on your WordPress installation you must delete the option_value content like you can see below.

IMPORTANT: You may be interested in saving your that value before deleting it just in case you want to restore it at a later time.

There is also a quicker way to do this by running this next SQL sentence. but I prefer the first way since I get to save the value before doing any changes to my database.

UPDATE wp_options SET option_value = '' WHERE option_name LIKE 'active_plugins'

Please let me know if you know other ways to disable all wordpress plugins directly from the database.

On the other hand this was forcing me to chmod wp-content/uploads  folder with 777 permissions. I am not a heavy image uploader, so when I was in need of updating I was just chmod to 777 and then, after uploading my stuff, get back to 755.

I am not a Linux lover, geek, guru (or how they call it) so I had no clue about why this happened on my VPS or how to fix that. But as a respectable “self-directed learner” as I am, I had to dig into the situation.

So this was my task list:

1. Make a list of errors and possible relationship between them – others then the obvious permissions issue
2. Gather some documentation on this and understand why it is happening in the first place
3. See how other solved the errors and how can I apply it to my case.
4.  Actually solve it on my Linux installation with Parallels Plesk  – and not die trying.

This are my issues

1. WordPress asks for FTP username and password while it’s uploading/upgrading a plugin, a theme or WP himself.
2. The 777 permissions are needed when I upload images (or any other media  files) to my uploads directory.
3. My mortgage is really expensive. (Later I have found out that this has nothing to do with the Apache permissions problem).

I was unable to upload images nor any other files using the WordPress Media Uploader. Could not upload plugins or themes via the WordPress automatic updater.

You don’t have to be a genius to know that images are uploaded via PHP and PHP is running on apache, so apache does not have permission to upload files. I seems that apache is a service and also a user in Linux. So after all, this it is a simple user permission.

Bottom line: Apache can not write to my WordPress folders

This is why all this happened in the first place

When mod_php is used to execute PHP scripts on a web server it does not have permission to write to the file system if it does not own it. I uploaded files via FTP. So the files were assigned to the ftp user and the Apache user does not have permission to edit them. This is really a common problem when working with a CMS like WordPress.

On the other hand, this also happen if a php process creates a file. This can not be later edited by the FTP user.

I had to set up PHP to run as FastCGI as it allows FTP and PHP scripts equal access, meaning file upload and edit functionality within the CMS works like a charm without any other special file permission configuration.

set up PHP to run as FastCGI

To do this in Plesk you will have to go to your domain Hosting Settings under the Websites & Domains tab.

Under the Web scripting and statistics secction you will se the PHP support option and you will have to change the Run PHP as part to the FastCGI Option.

Here is a complete explanation of all options available here with the pros and con that each one of them has a cording to the official Plesk Documentation and Help Portal. (https://docs.plesk.com/en-US/12.5/administrator-guide/web-hosting/php-management/php-handler-types.75145/)

This may also help. There is a special directive for wordpress for not to ask to FTP credentials. For this you can add the following line to your wp-config.php after define('WP_DEBUG', false); line.

define('FS_METHOD', direct);

Hope this helped you trow all the process. Please let me know if you think I have omitted something, or how it worked on your specific server configuration.

Although updates are a good thing to do, from a security point of view, there are some aspects that you will want to take into consideration when doing an update.

So you may want to choose the time of the update, you may want to choose what to update and most of all you would like to take a full backup, just in case things don’t go out well, specially when updating themes.

So if you want to have it all controlled and take decisions after you first test everything, you can completely disable all automatic updates by adding this line to your wp-config.php .

Disable WordPress Auto Updates:

define( 'AUTOMATIC_UPDATER_DISABLED', true );

WordPress sees two types of updates: minor and major. Major updates add additional functionality to the WordPress platform. This can be easily identified as WordPress 3.9, 4.0, 4.1  etc.

Minor updates are the updates of a major version of WordPress that was released to correct security holes and correct bugs. Their version number increases by 0.01. For example 4.2.1, 4.2.2, 4.2.3  etc.

By default, WordPress is configured to apply all minor updates automatically as soon as they are released.

Enable Core Updates for Minor Releases (default):

define( 'WP_AUTO_UPDATE_CORE', 'minor' );

If you want to disable core updates, you can do that by using the following line of code in your config file.

Disable All Core Updates

define( 'WP_AUTO_UPDATE_CORE', false );

YOu can also install automatically all minor and major updates of WordPress by adding the following code to wp-config.php.

Enable All Core Updates, Including Minor and Major:

define( 'WP_AUTO_UPDATE_CORE', true );

There are also other ways to achieves this. For example you can use filters in your themes function or in your plugin files.

Use filters to change updates status

Here is a simple way to control all WordPress core automatic update

// Disabling All Updates Via Filter
add_filter( 'automatic_updater_disabled', '__return_true' );

// Core Updates via Filter
add_filter( 'auto_update_core', '__return_false' );

//disable development updates 
add_filter( 'allow_dev_auto_core_updates', '__return_false' );

//disable minor updates
add_filter( 'allow_minor_auto_core_updates', '__return_false' );
 
//disable major updates      
add_filter( 'allow_major_auto_core_updates', '__return_false' );

And you can also control automatic updates of themes and plugins by using this filters:

// Disable automatic updates for All plugins:
add_filter( 'auto_update_plugin', '__return_false' );

// Disable automatic updates for All themes:
add_filter( 'auto_update_theme', '__return_false' );

And finally here is how you can disable the automatic update of the translation files

// To disable translation file updates, use the following:
add_filter( 'auto_update_translation', '__return_false' );

Hope this helps you in your projects, it certainly helped me

There is a not quite intuitive (for me) option in the Super admin dashboard that allows you to change this. Please note that this does not overwrite your apache or php.ini settings if this last one is smaller. Here you can apply the rule of the most restrictive.

So here are the steps to achieve this:

Here are the steps to change the Maximum upload file size within WP admin:

• Click Network Admin, at the top-left of your WordPress dashboard.
• In the main menu on your left side, just hover over Settings and then click network Settings.
• Scroll to the bottom and almost at the end of the list you will find the Max upload file size. You must specify a value in KB.
• Apply Changes and you are good to go.

Like I said, if your value is bigger than the one you have specified in your /etc/php.ini  or in your .htaccess , it will not been overwritten. You will have to further tweak your server settings to achieve your desired maximum upload file value in your WordPress multisite installation.

This are some value that may help you to get the job done:

post_max_size = 10M

upload_max_filesize = 10M

memory_limit = 64M

max_execution_time = 250

max_input_time = 250

On the other hand WordPress itself has another settings in the wp-config.php  file that may be tweaked.

define('WP_MEMORY_LIMIT', '10M');

So hope this helps you. I will soon post a specific tutorial about how to change the settings via your ini file, htaccess, or even directly in your php scripts. You can subscribe to receive it in your mailbox.

This is the first time I am playing with WordPress and the multisite feature, so I am learning from my mistakes. There is a small change that I missed the first time I have read the documentation in WP Codex about Moving WordPress:

If database name or user changes, edit wp-config.php to have the correct values.

Did you notice, the small “edit wp-config.php” in there. Well, I didn’t!!

Not doing this adjustment will end up in some errors on the multisite part. When trying to do to your Super Admin Dashboard you will be redirected to the old site domain and not be able to access the multisite dashboard menu.

This is due to the changes that you have done to activate multisite in your Super admin area, under Settings / Network configuration.

So to do this the right way you will have to edit the wp-config.php  as fallows:

/* Multisite */
define( 'WP_ALLOW_MULTISITE', true );
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', 'my-new-domain-name.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

Please note that I am not putting http://  nor the trailing slash  /      after  my-new-domain-name.com

Prepending your domain with www. depends of your preferences. I prefer no www and I have my own arguments for it, but this is another subject.

Well, this is all I had to say about this. It’s really nothing, but it made me lose a lot of time before I figure it out. Next time I will be paying more attention to the documentation. RTFM as other say

I needed to add a custom post houses so that the client would be able to add the content to the website, but on the other hand I did not need to use the standard post type since I did not need the blog or news section. So why not convert it to something else.

Here is a simple way to do it. Note that this only changes the Posts name to Houses and does not change the posts  slug to houses . So if you ever refer to the house post type in your coding you will still refer to “posts”. This also maintain any changes and customization that the theme made to the post type. Hope this is clear enough.

/*
 * Change 'post' name to 'Houses'
 */

function dev_edit_admin_menus() {
    global $menu;
    global $submenu;

    $menu[5][0] = 'Houses'; // Change Posts to Houses
    $submenu['edit.php'][5][0] = 'Houses';
    $submenu['edit.php'][10][0] = 'Add House';
    $submenu['edit.php'][16][0] = 'House Tags';
}

function dev_change_post_object() {
    global $wp_post_types;

    

    $labels = &$wp_post_types['post']->labels;



    $labels->name = 'Houses';
    $labels->singular_name = 'House';
    $labels->add_new = 'Add House';
    $labels->add_new_item = 'Add House';
    $labels->edit_item = 'Edit House';
    $labels->new_item = 'House';
    $labels->view_item = 'View House';
    $labels->search_items = 'Search Houses';
    $labels->not_found = 'No Houses found';
    $labels->not_found_in_trash = 'No Houses found in Trash';
    $labels->all_items = 'All Houses';
    $labels->menu_name = 'Houses';
    $labels->name_admin_bar = 'Houses';

    // print_r($labels);
}
 
add_action( 'admin_menu', 'dev_edit_admin_menus' );
add_action( 'init', 'dev_change_post_object' );

You can use the php print_r function to print all the array, just in case you will need to change some other value.

After I updated my child-theme function .php , the standard WordPress post type changed to my custom house type. Note that if you do not have a child theme, you can use your theme main function php or just create a simple plugin. There are lots of advantages saving all your modification in your own plugin. One is that you youre changes will persist while changing the theme. On the other hand you can easily migrate your changes to a different blog or website. But this is just another subject.

So let’s continue customizing the new transformed post type. Now it is called Houses and it has to be reflected in the fields structure. For this I have installed a plugin called Advanced Custom Fields from the free WordPress repo.

Please note that I am not related with the author of this plugin in any way

You have a large variety of field types you can create like you can see above. Just choose the one you need and follow the on-screen instruction.

Another cute feature that you have is the conditional logic. Used well this is a really powerful tool for creating dynamic fields on backend.

So I have created the fields set that I needed and assign them to my newly created post type. Remember that the new House is still a post type. So I will be assigning this to my “posts”.

Great!!! Now I have my posts called house and have a new set of custom fields assigned to them. But wold like to replace the main editor with my own customized one.

So here is how I do it in my child theme function.php.

/*
 * Remove standard WYSIWYG editor from post page
 */

function init_remove_wp_main_editor(){
    $post_type = 'post'; 
    remove_post_type_support( $post_type, 'editor');
}

add_action('init', 'init_remove_wp_main_editor',100);

Later edit: I have realized that the plugin has an option to hide fields that you do not want to be displayed on the edit post screen. So you can use that instead to hide the main editor or any other metabox you don’t want there.

Later you will have to retrieve all this field values on your theme’s front-end. But I’m not there yet. I will write a tutorial about this at a later time.

This is because WordPress and lots of plugins store data and full URI in the database using wp_serialize function. Here is a little example about what I am talking about:

a:6:s:4:"role";s:5:"admin";s:17:"includes_globally";s:2:"on";s:18:"pages_for_includes";s:0:"";s:12:"js_to_footer";s:2:"on";s:15:"show_dev_export";s:3:"off";s:11:"enable_logs";s:3:"off";}

If you just do a search and replace you will break all this fields and data can not be recovered.

WordPress itself in his Codex Archive about moving WordPress installation files and database recommends that you manually change the URL in the WordPress Control backend.

Doing this, will give you a 404 error page on the old domain, but after you move the files and database on the new server, your WordPress installation should work.

Please note that this process leaves you with lots of database entries containing the old domain URL. Entries like posts, data stored by themes and plugins will not be modified. On the other hand you can do a search and replace on your entire database to change the URLs, but this can cause major issues with serialized data because lots of themes plugins and widgets store values along with their length. This can be a big headache.

I am sure there are lots of tools out there, but today I will be talking about this PHP Search/Replace tool. Note that this tool is not specially designed for WordPress migration, but for any database search and replace process. It works great with WordPress installation and like you can see it has a very friendly interface. After you finish searching and replacing the database you can use the build in cleanup process or delete the files manually.

Please note that I am not related in any way with this guys. I am just happy to use their tool and post about it.

To run the search/replace script you will have to download it and place a copy on your website root folder. So your files will be something like this:

/your-custom-folder-for-search-replace-script
/wp-admin
/wp-content
/wp-includes

It is very important to place the script in his own folder because when it finishes the process it will attempt (give you the option of course) to delete himself. This will delete all files on the same level so if you place all the files directly on the root you will end up deleting all WP installation files. If you do not understand this just ask a geek for a little advice.

Remember that if you had any kind of permalinks rules it is very possible that they will not work properly after the WP migration. So you must disable .htaccess  and reconfigure permalinks.

Resetting the permalinks is quite easy and can be done in two ways:

• The first method is done in the WordPress dashboard. Just go to your WordPress dashboard, click on Settings and go to Permalinks.

Just click Save Settings and you should be good to go. If this does not work try to change to a different option, save and then change back to your desired permalink structure. This will force WordPress to rewrite the .htaccess  file.

• The second option is to manually edit the database. You will have to search your database wp_options table for a special entry called  permalink_structure . After you found it just edit it there.

Note that if you edit your settings via database or even if you are using the dashboard but WordPress does not have permission to write on file. You will have to manually edit your  .htaccess

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

If all this did not make your site to work properly, try to do a force refresh, clear cache or just use a different browser
