Validating extra fields on user signup

  • I’m building a plugin that should, among other things, add some fields to the user signup form. I’ve succeeded in adding them to the page using the signup_extra_fields hook, but I’m having a problem validating them. Non-MS WordPress has the registration_errors filter, but as I browse through wp-signup.php I don’t see anything analogous. Any suggestions?

    It should be the same filters.

    validate_user_form() comes to mind. What code do you have so far?

    Here’s some code. You’ll see I attempted to add a filter to the registration_errors hook. That function has a print_r() in it that doesn’t fire. Also, I had a look at validate_user_form(), and I’m pretty sure that just checks that the username and email aren’t taken.

    if (is_multisite()) {
	add_action('signup_extra_fields','show_dm_fields');
	add_filter('registration_errors', 'dm_cust_check_fields', 10, 3);  // isn't any filter hook
	add_filter('add_signup_meta', 'dm_cust_store_meta', 10, 3);
} 

function show_dm_fields($errors)
{
?>
