Roundtrip disallowed characters error

[eluser]freshface[/eluser]
When I have this error

The URI you submitted has disallowed characters.

I want to load an other view, but how do i fetch this in my controller?

Question is not clear to me..Give more detail

When somebody enters disallowed characters in the url i want to capture the error instead of showing the default CI error.
Edit, extending the permitted characters is not an option.

You can achieve a much neater “upgrade” to this error message without hacking the core files.

Simply make a file in your application’s “libraries” directory called MY_URI.php, and fill it with:

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_URI extends CI_URI {

    function _filter_uri($str)
    {
        if ($str != '' AND $this->config->item('permitted_uri_chars') != '')
        {
            if ( ! preg_match("|^[".preg_quote($this->config->item('permitted_uri_chars'))."]+$|i", $str))
            {
                show_404($str);
                exit();
            }
        }
            
        return $str;
    }
    
}

?>

i.e. a direct copy of the appropriate function from the core class, but with your new addition of show_404() too.
