Question

I am building a custom module in Drupal 7. I have a URL which is like “review/edit/2”; I want that number in the end of the URL.

How can I access it using hook_menu()? A small snippet would be good.

Answer 1

This is a very simple example that will pass everything after review/edit/ to your page callback function:

function mymodule_menu() {
  $items['review/edit/%'] = array(
    'title' => 'Title',
    'page callback' => 'mymodule_page_callback',
    'page arguments' => array(2),
    'access arguments' => array('access administration pages')
  );

  return $items;
}

function mymodule_page_callback($arg) {
  // For the URL review/edit/2, $arg is equal to 2
}
