Saving Objects In WordPress’ User Meta

There’s a hole in the wall at about head level next to my desk.

I’ve spent most of the day trying to track down a bug with some code I’ve been working on to add fields to a user’s profile in WordPress. The problem is that upon trying to save the profile I’d get an error like the following:

Catchable fatal error: Object of class stdClass could not be converted to string in /wp-includes/wp-db.php on line 472

Line 472 in my install is in the wpdb::escape() function. After poking around the wrong side of the problem, I finally broke down and rewrote the function along these lines:

function escape($string) {
 if( !is_object( $string ))
 return( $string );

 echo '<h2>'. $this->get_caller() .'</h2><pre>';
 print_r( $string );
 echo '</pre>';
 die();
}

That’s how I finally learned that wp_update_user() was at fault. I also opened a ticket for add_magic_quotes(), as both probably need independent fixes.

For now, however, I'm just converting the object to an array and avoiding the mess.
