I'm creating something similar to MySpace.com, but I don't want users to be able to enter HTML or style sheets in the text input & textarea boxes. On MySpace, you can change the look of your individual profile page by entering HTML & style sheets into the text boxes. I want to PREVENT users from being able to do this on my site.
So, the simple question is, how do you NOT allow users to enter HTML into a text field? Is there an easy way to only allow text?
