Securing a user input - need some confirmation

Posted on 16th Feb 2014 07:03 pm by admin

Hello All,

I am in the process of recoding a large proportion of an e-commerce site, one of the problems is that there are a few security issues floating around.

I have a search box which was originally unprotected against XSS, I was easily able to execute JavaScript and force the system to echo out HTML *holds head in hands*.

I am using this code:

$term=preg_replace('/[^a-zA-Z0-9s]/', "", $term); remove any non-alphanumeric characters (excluding spaces), I am thinking because this will strip out any characters like ', ", <, >, /, = etc, it should make my script safe again.

Can you confirm this, or is there something that I am missing?

Many thanks
