# Multiple specific posts using wp_query and post__in array – EXPLAINED

 * This is a placeholder solution snippet for anyone who encountered the same problem
   I did.
 * This DOES NOT work:
 *     ```
       function doProduct($allTypes) {
       //Where $allTypes is a string "1, 2, 3, 4"
   
       $args = array(
       'post_type' => 'product',
       'categories'	=> 'misc',
       'post_status' =>	'publish',
       'post__in' => array($allTypes)
       );
   
       ...
       }
       ```
   
 * So even though $allTypes is a literal string “1, 2, 3, 4” that would look EXACTLY
   like what you might have typed into the array yourself, it doesn’t work.
 * This DOES work:
 *     ```
       function doProduct($allTypes) {
       //Where $allTypes is a string "1, 2, 3, 4"
   
       $args = array(
       'post_type' => 'product',
       'categories'	=> 'misc',
       'post_status' =>	'publish',
       'post__in' => explode(',', $allTypes)
       );
   
       ...
       }
       ```
   
 * Don’t ask me why. Another reason why WordPress is more like KlugePress…or maybe
   it’s just screwy PHP.
