Does anyone know fo an easy way to prevent people from inputting html into a form. I dont mean in the text box, but just a way to check for it and stop the script. I dont want people including html tags in their posts that could be any type of security threat or anything, but I would like them to be able to use certain text formatting tags. Thanks

you could just apply the htmlspecialchars function to what they input, it won't stop the script but it will keep the html tags from displaying as html. you can get more info at http://www.php.net

Thanks a million. I have trouble finding those nice little tags on php.net sometimes, and my php book just plain sucks

no problem, that's what we're here for, if you're looking for a good PHP/MySQL reference book, check out PHP and MySQL Web Development by Luke Welling and Laura Thomson.
