Removing featured image from gallery?

1 comment

1. Assuming that you are using the standard functionality of the gallery:

   [gallery ids = "1,2,3,4,5,6,7,8"]
   

   You can extract the id of the images without having to do a query for attachments of that post
   with:

   preg_match('/[gallery.*ids=.(.*).]/', get_the_content(), $ids);
   

   Then make an array of these values:

   $ids = explode( ',' $ids[1] );
   

   Eventually check if the id of the featured image exists and get its position( i think that it doesn’t exists till you don’t place it inside the gallery ):

   $pos = array_search( get_post_thumbnail_id( get_the_ID ), $ids);
   

   unset that value:

   unset($ids[$pos]);
   

   now you have all the attachments ids, less the one of featured image stored in $ids array.
