jQuery validator and a custom rule that uses AJAX
- by thatweblook
Hi,
I read your reply regarding the jQuery validator where you outline a method to check a username against a value in a database.
Ive tried implementing this method but no matter what is returned from the PHP file I always get the message that the username is already taken.
Here is ths custom method...
$.validator.addMethod("uniqueUserName", function(value, element) {
$.ajax({
type: "POST",
url: "php/get_save_status.php",
data: "checkUsername="+value,
dataType:"html",
success: function(msg)
{
// if the user exists, it returns a string "true"
if(msg == "true")
return false; // already exists
return true; // username is free to use
}
})}, "Username is Already Taken");
And here is the validate code...
username: {
required: true,
uniqueUserName: true
},
Is there a specific way i am supposed to return the message from php.
Thanks
A
