how to protect a controller function accessing by URL

[eluser]Tracker[/eluser]
I don't want to access "deleteItems" function directly like this.
http://localhost/Shop/deleteItems/3

it should only accessible if i will call
http://localhost/Shop/deleteShop/3

Your help will be appreciated...

Code:

class Shop extends Controller {

    function deleteShop()
    {
        $this-> deleteItems($shopId);
        //….

    }

    function deleteItems($shopId)
    {
        //….

    }
}

This is covered in the user guide.

In some cases you may want certain functions hidden from public access. To make a function private, simply add an underscore as the name prefix and it will not be served via a URL request. For example, if you were to have a function like this:

Code:

function _utility()
{
  // some code
}

Trying to access it via the URL, like this, will not work:

Code:

example.com/index.php/blog/_utility/
