Drupal 7 hook menu page arguments

Why not I thought Drupal already provides bulk of the server-side framework for the purpose, and Ajax should be a breeze with jQuery.

Passing Default Arguments in your Menu In the last article we saw that the Drupal menu system passes any additional parameters in the URL as arguments. In many modules there is one common generic menu callback function, which responds to multiple menu items.

Some menu items might have an extra parameter and some might not. In order to use the same callback function the menu item in Drupal can define default arguments that will be passed to the callback function.

And the callback can have its normal code which would expect certain arguments to process the output. We add default arguments for our menu items as follows: Now if you click on the menu item the output will be as follows If you want to specify that the first argument passed to the callback function is a product and the second argument to the callback function should be fetched from the URL, you can update the menu item definition as follows: Using Wild Cards in Menu Sometimes you might want to respond to the URL in that you might not want to hardcode some parts of the URL, and that could be anything that then would be passed to your callback function.

Drupal lets you specify such wild cards in your URL. The element at position 1, which is the wildcard string, will be passed as the argument to the callback function. Loading objects with wild card Sometimes you might not just want the wildcard value passed directly to the callback function, but might want to take that value and then do some processing or fetch some other information based on that argument, and then pass that information to the callback function.

The Drupal framework allows you to do that by specifying a load function that will be written after the wildcard in the menuitem definition. To specify a load function with the wildcard the menu definition will be as follows: In this argument we have just returned an array defining the product with that id.

You could fetch the details in the load function from a database or from some file. Creating a Tabbed menu The Drupal framework also lets you create tabbed menus.

To define a tabbed menu first we have to define a normal menu item, then define a local default task, and then define different local tasks depending on the number of tabs you want.

The menu definition to create three tabs is as follows: View all Product tab and Edit all Products tab. The callback function just displays whichever tab is clicked.

You may be familiar with the theme information link in views. The theme information link in view tells us which files are to be modified, to theme the view. With page_arguments, we can create dynamic paths for custom pages and page ph-vs.com allows us to use one path to handle a wide variety of contexts about users, nodes, views contextual filters, etc.

Say for example we wanted to create a user dashboard that was unique to each Drupal user account. This article is about creating URL alias for a custom menu that we created in our custom module.
