How would I filter the WordPress oEmbed provider list? My aim is to allow just Twitter and Youtube.
EDIT: Could I do something like this?
function filter_oembed_provider_list( $array ) {
$array = array( 'http://youtu.be/*' => array( 'http://www.youtube.com/oembed', false ) );
return $array;
}
add_filter( 'oembed_providers', 'filter_oembed_provider_list' );
But this doesn’t seem to work.
Please see the relevant code in class-oembed.php:
apply_filters( 'oembed_providers', array(
'#https?://(www.)?youtube.com/watch.*#i' => array( 'http://www.youtube.com/oembed', true ),
'http://youtu.be/*' => array( 'http://www.youtube.com/oembed', false ),
'http://blip.tv/*' => array( 'http://blip.tv/oembed/', false ),
'#https?://(www.)?vimeo.com/.*#i' => array( 'http://vimeo.com/api/oembed.{format}', true ),
'#https?://(www.)?dailymotion.com/.*#i' => array( 'http://www.dailymotion.com/services/oembed', true ),
'http://dai.ly/*' => array( 'http://www.dailymotion.com/services/oembed', false ),
'#https?://(www.)?flickr.com/.*#i' => array( 'http://www.flickr.com/services/oembed/', true ),
'http://flic.kr/*' => array( 'http://www.flickr.com/services/oembed/', false ),

'http://qik.com/*' => array( 'http://qik.com/api/oembed.{format}', false ),
'http://revision3.com/*' => array( 'http://revision3.com/api/oembed/', false ),
'http://i*.photobucket.com/albums/*' => array( 'http://photobucket.com/oembed', false ),
'http://gi*.photobucket.com/groups/*' => array( 'http://photobucket.com/oembed', false ),
'#https?://(www.)?scribd.com/.*#i' => array( 'http://www.scribd.com/services/oembed', true ),
'http://wordpress.tv/*' => array( 'http://wordpress.tv/oembed/', false ),
'#https?://(.+.)?polldaddy.com/.*#i' => array( 'http://polldaddy.com/oembed/', true ),
'#https?://(www.)?funnyordie.com/videos/.*#i' => array( 'http://www.funnyordie.com/oembed', true ),
'#https?://(www.)?twitter.com/.+?/status(es)?/.*#i'=> array( 'http://api.twitter.com/1/statuses/oembed.{format}', true ),
'#https?://(www.)?soundcloud.com/.*#i' => array( 'http://soundcloud.com/oembed', true ),
'#https?://(www.)?slideshare.net/*#' => array( 'http://www.slideshare.net/api/oembed/2', true ),
'#http://instagr(.am|am.com)/p/.*#i' => array( 'http://api.instagram.com/oembed', true ),
'#https?://(www.)?rdio.com/.*#i' => array( 'http://www.rdio.com/api/oembed/', true ),
'#https?://rd.io/x/.*#i' => array( 'http://www.rdio.com/api/oembed/', true ),
'#https?://(open|play).spotify.com/.*#i' => array( 'https://embed.spotify.com/oembed/', true ),
) );
There is a built-in function
wp_oembed_remove_provider
, respectivelywp_oembed_add_provider
.EDIT
add to functions.php file

I looked into it, and I found out, that you can use a filter
oembed_providers
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.(Despite of the fact, that it works, i still do not get a usage of this filter :-D)
EDIT 3
Finally, I got it working.
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.
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
*_postmeta
under key_oembed_â¦
If the filter you provided (
oembed_providers
) is working for you, then you might try something like this:where you must edit the
$whitelist
to your needs.Update:
Thanks to @Ivan Hanák, for suggesting the post saving part 😉
This snippet should now work, after you update the oEmbed cache, by saving the post 😉
I had the same need, as instagram Oembeds are broken in WordPress before 4.4.
what I realized is that the filter for the providers run before your Theme is initialized, so if you want to add this filter, you have to use a plugin.This is what I used
so you must
1) create a folder like instagram-oembed-fix in the plugin folder
2) create a file named instagram-oembed-fix.php
3) copy over the php code above
4) activate your plugin ( network activate in a network )
5) regenerate oEmbed cache by going to any post and presing “Save”
