Better regex for get_video_id function
Today i was trying to show this video https://www.youtube.com/embed/JaNH56Vpg-A or https://www.youtube.com/embed/JaNH56Vpg-A
and both URLs wasn't working. So i've made a fix for that and this is the code:
function get_video_id($url)
{
// Handles normal youtube url e.g:
// http://www.youtube.com/watch?v=QRS8MkLhQmM
$regex1 = '#v=([^\s]{0,11})#is';
// Handles youtube share short links e.g:
// http://youtu.be/QRS8MkLhQmM
$regex2 = '#.*youtu\.be\/([^\s]{0,11})#is';
// Handles embedded youtube video url e.g:
// http://www.youtube.com/v/QRS8MkLhQmM?version=3&feature=player_embedded&autohide=1
// http://www.youtube.com/embed/QRS8MkLhQmM?version=3&feature=player_embedded&autohide=1
$regex3 = '#(?<=[v|embed])\/[v|embed]+\/([^\s]{0,11})#is';
// Handles videos IDs e.g:
// QRS8MkLhQmM
$regex4 = '#([^\s]{0,11})#is';
if ( preg_match($regex1, $url, $matches)
|| preg_match($regex2, $url, $matches)
|| preg_match($regex3, $url, $matches)
|| preg_match($regex4, $url, $matches) ) {
return $matches[1];
}
return 'QRS8MkLhQmM'; // default video ID on error
}

Hi Alysson, thanks for reporting your issues!!
I've already improved that function for version 1.9 so that it recognises the following "new" URLs:
- Support for Youtube SSL URLs: https://
- Support for Youtube embed URLs: http://www.youtube.com/v/VIDEO_ID and http://www.youtube.com/embed/VIDEO_IDUntil I release version 1.9 I'll leave here the new code for the function get_video_id so you can use it today:
function get_video_id($url)
{
if (preg_match('#^https?\://(?:(?:[a-z0-9-_\.]+\.|)youtube\.com/(?:watch\?v=|v/|embed/)|youtu\.be/)([a-z0-9-_]+)|^([a-z0-9-_]+)$#i', $url, $matches) > 0) {
return $matches[empty($matches[1]) ? 2 : 1];
}
// default video ID on error
return 'QRS8MkLhQmM';
}It passes all unit tests.
Cheers!
