 * Hi guys, i’m using the post from site plugin and im wondering if I can make it
   so someone HAS to upload a photo to make a post also, along with the content,
   here is the code:
 *     ```
       <?php
       /* * *
        * Processed form data into a proper post array, uses wp_insert_post() to add post.
        *
        * @param array $pfs_data POSTed array of data from the form
        */
       require('../../../wp-load.php');
       error_reporting(E_ALL);
       ini_set('display_errors',1);
   
       /**
        * Create post from form data, including uploading images
        * @param array $post
        * @param array $files
        * @return string success or error message.
        */
