In an HTML web form, how to create a checkbox that will block submission of the form unless checked?

Asked by PupnTaco (13895points) September 1st, 2008

Ugh, I hate this stuff. I have a web form that will either send its contents to a SQL database or to an e-mail. My client wants to block submission of the form unless an “I agree” checkbox is ticked. How the heck do I do this?

It’s easily circumventable (is that actually a word?) (see the “Tamper Data” Firefox extension), but I suppose you can convince your client you’ve done it using Javascript (not sure how to do that though). However, be sure to do server-side validation as well, because, as I said, it’s easy to work around (you can just disable Javascript).
