Handling of errors in wp-login.php

[dtc]

Hello,

There has been some changes in the way errors are handled in wp-login.php : in WP 2.3.x, there was a global array defined ($errors[]) which could be interacted with via plugins :

$errors['user_email'] = __('<strong>ERROR</strong>: The email address
is not correct.');

With WP2.5, plugins can't seem to add to $errors->add(). I think I've tried every possibility and I cannot make out why in a plugin something like :

$errors->add('invalid_email', __('<strong>ERROR</strong>: The email
address is not correct.'));

does not work. I should say that it is part of a function that is inserted through add_action('register_post').

Add that line make wp-login.php go blank.
