    <p>There is a built-in function <a href="https://codex.wordpress.org/Function_Reference/wp_oembed_remove_provider" rel="nofollow"><code>wp_oembed_remove_provider</code></a>, respectively <a href="https://codex.wordpress.org/Function_Reference/wp_oembed_add_provider" rel="nofollow"><code>wp_oembed_add_provider</code></a>.</p> <p><strong>EDIT</strong></p> <p>add to functions.php file</p> <pre><code>function customize_oembed() { //load oembed class require_once ABSPATH . DIRECTORY_SEPARATOR . 'wp-includes' . DIRECTORY_SEPARATOR . 'class-oembed.php'; //get a singleton object $oembed = _wp_oembed_get_object(); /** * Forget about those lines * //empty the providers list $oembed-&gt;providers = array(); //add what you want wp_oembed_add_provider( 'http://site.com/watchvideo/*', 'http://site.com/oembedprovider' ); */ //use applying a filter $providers = array( 'youtube' =&gt; array( 'http://www.youtube.com/oembed', false), 'twitter'=&gt; array( 'http://api.twitter.com/1/statuses/oembed.{format}', true ) ); $oembed-&gt;providers = apply_filters('oembed_providers', $providers); } add_action('init', 'customize_oembed'); </code></pre> <p><strong>EDIT 2</strong></p> <p>I looked into it, and I found out, that you can use a filter <code>oembed_providers</code> exactly in the same way, as it is used in a constructor of the class. Therefore using additional wordpress functions, which would again try to require the class file and instantiate a singleton object, is useless, when you can do it in one function.</p> <p>(Despite of the fact, that it works, i still do not get a usage of this filter :-D)</p> <p><strong>EDIT 3</strong></p> <p>Finally, I got it working.</p> <p>It is really similar code to yours, though the argument in the function is basically useless. It only gives you original providers, which you want to override, so you are not using it and you can return an array directly.</p> <p>Maybe the important thing to remember is, after editing your list, you need to update your posts, since wordpress is saving some data into table <code>*_postmeta</code> under key <code>_oembed_…</code></p> <pre><code>function filter_oembed_provider_list( ) { return array( 'http://youtu.be/*' =&gt; array( 'http://www.youtube.com/oembed', false ) ); } add_filter( 'oembed_providers', 'filter_oembed_provider_list' ); </code></pre>

    1. COI am aware of the function although I'd prefer to filter the list because each time WordPress adds a new provider to the list which they will do regularly, I'll have to add another wp_oembed_remove_provider

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
