php - module regex not working -

-

i add regex validation input given user in opencart 2.0.0.0 module. i'm trying validate inside validate() in newmodule.php.

but cant perfect output preg_match(). after gone through on regex pattern.

and there found < doing serious problem. got value entered user following function.

$this->request->post['variable'];

i printed value. looks user given. < not matched in preg_match()...

is there opencart doing type of encoding works?

following code

$var = $this->request->post['code_script']; if(preg_match( "/<script>/s", $var )) {     $this->error['code'] = $this->language->get('error_invalid'); }
