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.
 */
