[quote author="iFadey" date="1257431813"]This is what he's saying. He don't want to use

Code:

$this->input->xss_clean();

He wants to use global xss filter which can be enabled from config.php file. So the problem is his global xss filter is not working.[/quote]

I never said that he should stick with it. I wanted to know if it worked. Or wasn't that clear when I asked, "what happens when you use $this->input->xss_clean()"?
