I have a classified ad site, and I just display the user's input on the ad page.

<b>Is there any advanced filters that will prevent someone entering bad scripts on the initial insert page?</b>

i.e.

<pre id=code><font face=courier size=2 id=code>&lt;a href="javascript:evil_function();"&gt;My_Site&lt;/a&gt; </font id=code></pre id=code>

thanks

WHat language are you using? php or asp?

PHP
