Hello Experts. I am having one registration form and I want to check username that user have entered is already available in the database or not by clicking on submit button and printing that it is available or not on the same form without reloading the page. How can I do it? Please help me. Thanks in advance.
Try this one: http://roshanbh.com.np/2008/04/check-username-available-ajax-php-jquery.html You need to use Ajax to do this without any submission. Make sure that you are still validating on your submission page because this will not work if javascript is turned off.
