It is easy to disable oEmbed on the front end Disable automatic oEmbed of a youtube url within the content, but this leaves us with the editor shows a video (in the case of youtube) where on the front end there will be only a URL.
How can it be disabled on the editor side as well?
The quick way to disable oEmbeds would be
add_filter( 'pre_oembed_result', '__return_false' );
If you want to disable it for all external links then try:
/**
* Disable oEmbeds for external links
*/
add_filter( 'pre_oembed_result', function( $result, $url, $args )
{
if( parse_url( home_url(), PHP_URL_HOST ) !== parse_url( $url, PHP_URL_HOST ) )
$result = false;
return $result;
}, 999, 3 );
This is a modification from a more detailed answer I posted here.
post_ID, type=embed, action=parse-embed and shortcode, within our pre_oembed_result callback, but then we would need to remove the post type from wp_ajax_oembed_cache() through the embed_cache_oembed_types filter or check GET variables. Sounds hackish. Maybe there are other ways to stop the ajax calls for given post types?
