I have a text box such as where I'm writing this message and I'd like to add a custom form in there made of only html.

Actually, what I want to add is the Paypal Buy Now now button, which is a form with hidden fields, and submit button is an image. If i just copy paste, the hidden fields become text boxes and it doesn't show properly, so how I 'escape' from php and just the raw html?

Thanks.
