Thread: Make URL compulsory

I know how to make e mail a compulsory field but
May I know how to make URL a compulsory field, too?
Thanks.

For email you can use the BV built in validation.

For the URL valiodation you need to serach, find and install some additional Javascript. If you don't mind checking the format, you can make it mandatory validating it as text / required

I found this AJAX scripts . (what are AJAX or Java scripts)

How to apply it into form from BV page?

This is just a generic script to make Ajax requests, it is not applicable to your form unless you also implement a custom made Javascript function to handle the server response, and a php script on the server to make the validation.
