Disbale HTML on Input

[D_tunisia]

I know about HTMLENTITIES() but is there a way to prevent HTML as it is being input to a form rather than as it is being output to a page?

You could use say, javascript, but you cant really trust that.

An alternative is to use htmlentities(), htmlspecialchars() or strip_tags() before storing the data.

My objection to that would be that the data size would increase, and the data might be less flexible.
