Scan post for YouTube embed and insert into custom Field

  • Hi,
    I am migrating a fairly large wp site and changing themes. The old theme has youtube videos embeded but the new one requires the youtube url to be entered into the custom field.

    Can anyone help me out? I can’t find a plugin for this.

    The custom field’s key is ‘Iframe’ so I need to be able to get from the the current post’s content the ” https://www.youtube.com/embed/xxxxxxx ” (src=”www.youtube.com/embed/xxxxxxx”) then use it to insert into the the custom field the value “www.youtube.com/embed/xxxxxxx” where the custom field’s key=iFrame

    Any help or pointer would be very much appreciated.

    I saw this but I must be missing something as it doesn’t insert the youtube link into my custom field:

    add_action('save_post','get_youtube');

function get_youtube($postID, $post) 

$content = $_POST['get_the_content'];
if (preg_match('/http:\/\/www.youtube\.com\/embed\/([a-zA-Z0-9\-\_]{11})/', $content, $yturl) !='') {
$ytid = substr($yturl[0], 25, 31);
$custom = 'https://www.youtube.com/embed/'.$ytid.';
update_custom_meta($postID, $custom ,'iFrame');
}
elseif (preg_match('/http(v|vh|vhd):\/\/([a-zA-Z0-9\-\_]+\.|)youtube\.com\/watch(\?v\=|\/v\/)([a-zA-Z0-9\-\_]{11})([^<\s]*)/', $content, $yturl) !='') {
$custom = 'https://www.youtube.com/embed/'.$ytid.';
update_custom_meta($postID, $custom ,'iFrame');
}
}

function update_custom_meta($postID, $newvalue, $field_name) {
// To create new meta
if(!get_post_meta($postID, $field_name)){
add_post_meta($postID, $field_name, $newvalue);
}else{
// or to update existing meta
update_post_meta($postID, $field_name, $newvalue);
}
}
