Add the below code at the end of your theme’s functions.php file or you can also add the below code inside your site-specific plugin.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | function has_embed( $post_id = false ) { if( !$post_id ) $post_id = get_the_ID(); else $post_id = absint( $post_id ); if( !$post_id ) return false; $post_meta = get_post_custom_keys( $post_id ); $post_meta = array_map( 'trim' , $post_meta ); foreach( $post_meta as $meta ) { if( '_oembed' != substr( $meta , 0 , 7 ) ) continue; return true; } return false; } |
You’d use the function in the same way you check if a post has a tag. This function returns true if an embed is found, false on fail.
1 2 3 | if( has_embed() ) { //do whatever } |
