Question

It's working perfectly untill I need to make unique check to email field through ajax to check with the database..

I didn't know how to make the plugin make a unique validation to email from db.

I reckon you are refering to using an AJAX call (via the plugin) to check for unique email with the server, yea?

I would suggest using the addMethod of the validation plugin to create a custom validation in which you can make an AJAX call (which will be part of the jQuery core).

There's an SO post on this topic which you can explore:

Do note that you will have to implement the server-side script yourself.
