Custom Error Pages for particular controllers in CodeIgniter

Question

If we call a method abc() within a controller named Example. Suppose abc() is not present in Example controller.

In such cases i need to display a custom error message instead of

---

404 Page Not Found

The page you requested was not found.

---

for this particular controller only.

I know we can set custom error pages, but it applies to all controller. I need to use it with one controller only.

For Eg:

class Example extends CI_Controller
{
    function index()
    {
        echo "index page";
    }

    function xyz() 
    {
        echo "xyz page";
    }
}

if i call example/xyz it displays output as 'xyz page'

but if i call example/abc it show page not found error. (i need custom message for this controller only).

Thank You...

You can do something similar to below. If the method exists call it otherwise display your own error message.

function _remap( $method )
{
    // $method contains the second segment of your URI
    if(method_exists($this, $method ) )     
    {
         $this->$method();
    }
    else
    {
         //your custom coding here
    }
}
