I want to ajax script for form validation

I want to ajax script for form validation and check email id allready exist in database or not.

 

Ok we can do this using jquery .Please PM

 

it's so simple read this tutorial , google "ajax form validation" and click the jqueryfordesigners link.

 

you can do it with both jquery & ajax

 

Send the server the email address. Use a SELECT statement (in the server) to query the database. One or more rows returned indicates that the email address exists in the database. (Depending on what you're doing, more than one row may indicate a potential problem.)

 

there's lots of plugins that do this in jquery
search on google and you ill find them
