TalkPHP - View Single Post - how to do form handling(validation and security) in php

It's fine to use JavaScript, and better for usability. However, to use ONLY JavaScript to validate forms is very bad. JavaScript is a client-side scripting language and can therefore be manipulated, and disabled.

If you're going to validate using JavaScript, then you still need the validation in PHP.
