I'm building a sort of blog system, but I'm having trouble with editing an existing 'post' in the system. It is collecting the data from the database, and it displays it. But when I click the update button, I get this error. I've looked for it, checked my code couple of times, but I just couldn't find anything. This is the error.
SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens
And this is my code.
<?php //include config
require_once('../../includes/config.php');
//if not logged in redirect to login page
if(!$user->is_logged_in()){ header('Location: login.php'); }
?>
