permitted_uri_chars and $_GET

Code:

http://www.mysite/controller/action/?val=1&val=2

When you try this, CodeIgniter will consider the "?val=1&val=2" as a third segment and try to pass it as a parameter to your "action" function. The best way to do this is:

Code:

http://www.mysite/controller/action/1/2

Where 1 and 2 will be the values passed to the function. Your controller could be:

Code:

class Test extendes Controller {

  function index() {
    // default function
  }

  function action($val1,$val2) {
    echo 'Value 1 = ',$val1,'<br />';
    echo 'Value 2 = ',$val2;
  }

}

So, if you call the address "http://www.mysite.com/test/action/123/456", it will display:

Value 1 = 123
Value 2 = 456

As I said before, this way is more search engine friendly, more readable and more secure.
