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.
