AJAX custom validation rule

[luesakParticipant]

Hi,

I have a registration form. I need to check whether the email in the form already exists in the database. I am thinking to use a custom validation rule and send an AJAX request to get a count of the email address matching the one that is on the form. If count = 0, then ok if not then fail.

AJAX being async… wouldn’t the validation rule immediately exit before it even got a chance to return from the database and validate the results?

Please show an example of how I can achieve this.

And your forum has no search!!! It’s very difficult to find information.

Hi Kim,

1. The Forum has Search and it is on the top-right corner of your screen after logging in. Note the Search button, when you click it, you will see a search textbox.
2. This is a sample with Ajax Validation: registration_form.htm.
