confirm email field for registration

Aloha Jason!

We’ve had a number of users typo their email addresses upon registration. What’s the best way to add a second email address field with a validation rule enforcing it matches the default email field (like the confirm password field)?

Mahalo!

Hi John.

You’d need to add the extra field and some JavaScript that’ll compare them and give a warning preventing form submission if there’s a mismatch.

Maybe there’s a plugin to add that to wp-login.php?action=register. http://wordpress.org/extend/plugins/
