WordPress – Custom username validation
Ever wanted to use a Gmail alias e-mailaddress as a username in WordPress?
Noticed that WordPress doesn’t like that?
That’s where the validate_username filter comes in handy.
Paste the code below somewhere in your functions.php and start accepting GMail aliasses as usernames!
add_filter('validate_username', 'my_validate_username', 10, 2); function my_validate_username($valid, $username) { $sanitized = sanitize_user($username, false); $valid = ($sanitized == $username && !empty($sanitized)); return $valid; }
Enjoy!
