Shaun Andrews on improving WordPress Widgets
Some great thoughts on improving WordPress Widgets. The admin-UI changes are totally convincing. I’d like to see some thoughts on how to solve the “How do I install widgets” problem. The comments, too, on widgets per post are absolutely worth reading.

WordPress register with email only, using Gravity Forms and User Registration add-on
<?php
/**
* WordPress register with email only, make it possible to register with email
* as username in a multisite installation
* @param Array $result Result array of the wpmu_validate_user_signup-function
* @return Array Altered result array
*/
function custom_register_with_email($result) {
if ( $result['user_name'] != '' && is_email( $result['user_name'] ) ) {
unset( $result['errors']->errors['user_name'] );
}
return $result;
}
add_filter('wpmu_validate_user_signup','custom_register_with_email');
?>
The snippet’s story
A few days ago, I implemented a custom user registration with WordPress. I used Gravity Forms with the User Registration add-on, which worked fine when the user had to choose a username manually. But we also wanted a quick-registration option on the homepage, which we wanted to work with only one form-field asking for an email-address. So I built a Gravity Form with just an email field and added a User Registration with the email-field linked both as the required user’s email and username.
This works fine with a single install, but with a multi-site installation the wpmu_validate_user_signup-function is used and we got an “Only lowercase letters (a-z) and numbers are allowed.” error-message. The above filter fixes this issue by undoing this validation error and forcing WordPress to accept an email address as username.
