Disable HTML in Forms

Hi. I was just wondering. When you're making your own thing like a guestbook or something like that, how do you going about allowing or disallowing HTML in the forms in order to prevent bad input?

Any help is much appreciated.

If your page is powered by vB, use htmlspecialchars_uni() which specifically supports Unicode.

Thanks, so how would I use that, Do I just put it somewhere on the page?

Also, would it work in a non vB powered page?

htmlspecialchars() is a standard PHP function and will work on any PHP page. htmlspecialchars_uni() will only work on pages powered by vBulletin.

Run htmlspecialchars() on the variable that contains the input from the form, for example:

PHP Code:


		
			
$text_without_html = htmlspecialchars($_POST['message']);
