Question

WordPress 3.2.2

What’s the steps to define a custom link in the wordpress admin such as

http://localhost:8888/wp-admin/admin.php?action=update_posts

so that when this link is accessible by admins, a specific function is executed.

(in the context of a custom wordpress plugin)

EXAMPLE CODE

function my_special_function(){

    echo '<div> Hello World </div>';

}

$page_title = "Hello Page Title";
$menu_title = "Hello Menu Title";
$capability = "import";
$menu_slug = "My Menu Slug";
$function = my_special_function;
add_menu_page($page_title,  $menu_title, $capability, $menu_slug, $function);

So I have this example code. Now what? And what url should I load to see hello world printed on in the html page?

You will probably want to use add_menu_page. That involves two steps. First, you will need to define a function (my_menu_page in the example below) to create the menu.

// inside plugin file
function my_menu_page ()
{
  $page_title = "Hello Page Title";
  $menu_title = "Hello Menu Title";
  $capability = "import";
  $menu_slug = "My Menu Slug";
  $function = my_special_function;

  add_menu_page($page_title,  $menu_title, $capability, $menu_slug, $function);
}

Once you’ve got that, you will need to register it with WP using the add_action function and a hook. For an admin menu, the admin_menu hook is probably appropriate.

// inside plugin file
add_action('admin_menu', 'my_menu_page');
