 * Hello, and thank you for even taking a look! I am integrating a ‘favorite post’
   system into the wordpress installation i am working on which allows users to 
   choose their favorite videos to be posted to their profile. I have created a 
   form buttun with hidden values which passes the users data as well as the id 
   of the video to a form via POST in a separate php file. I have a little Javascript
   running on the page to prevent a refresh while the page is being viewed and just
   sends the info without causing any page disruption.
 * I have tested the wpdb query i am trying to execute on a different page, and 
   it seems to work fine. the problem arises in the query when the query is executed
   from a separate php page called through submission of the form.
 *     ```
       <?php 
   
       if(isset($_POST['favvid'])){
   
       $the_vid = ($_POST['favvid']);
       $user_id = ($_POST['userid']);
       $favs_array = ($_POST['favs']);
   
       $_favs_array = explode(",",$favs_array);
       $_favs_array[] = $the_vid;
       $new_favs = implode(",", $_favs_array);
   
       //------ Everything up to this point functions fine ------- //
       global $wpdb;
       $wpdb->query("UPDATE $wpdb->users SET favorite_vids = '$new_favs' WHERE $wpdb->users.ID = '$user_id' LIMIT 1");?>
   
       ?>
       ```
   
 * The page which this from is on is located in the theme directory along with the
   rest of the theme files.
 * Any ideas or suggestions as to where to start tackling this issue would be greatly
   appreciated 🙂

 * Whoops, under the code, i meant to say is that the code above is in getfav.php
   where the form submitting the POST to getfav.php is on a separate page also in
   the theme directory, thx!
