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

For anyone else who stumbles upon this, validate supports 'remote' method, which may not have existed in 2010:
https://jqueryvalidation.org/remote-method/
$("#myform").validate({
rules: {
email: {
required: true,
email: true,
remote: {
url: "check-email.php",
type: "post",
data: {
username: function() {
return $("#username").val();
}
}
}
}
}
});
