jquery validation with ajax call

Question

I am using the jquery validation and i need to validate an email.

I use

    $(\"#myForm\").validate({
        rules: 
            email: {
                   


        

Answer 1

remote: "/some/remote/path"

That path will be passed the value of the field in a $_GET. so.. what actually gets called in your case would be:

/some/remote/path?email=someemailuriencoded

Have the server side code return just the text true or false.

Then the corresponding message also named remote.

remote: "The corresponding email already exists"

My code for something similar:

$("#password_reset").validate({
  rules: { 
    email: { required: true, email: true, minlength: 6, remote: "/ajax/password/check_email" }
  }, 
  messages: { 
    email: { required: "Please enter a valid email address", minlength: "Please enter a valid email address", email: "Please enter a valid email address", remote: "This email is not registered" }
  }, 
  onkeyup: false,
  onblur: true
});

The corresponding server side code in php:

$email_exists = $db->prows('SELECT user_id FROM users WHERE email = ? LIMIT 1', 's' , $_GET['email'] );
if ( $email_exists ) { echo 'true'; } else { echo 'false'; }
exit;

Of course that's using my database abstraction stuff, but you get it.
