Drupal 7 hook menu validating argument from url


To avoid duplicating code that converts this ID into it's corresponding object, Drupal support autoloading for "named" wildcards.When a named wildcard is used, Drupal will check for a function with the same name as the wildcard, suffixed by is necessary to make the simple example above viewable at all, but it's hardly ideal, as it allows no control what so ever.Anyone that tries to visit /hello will be granted access.The easiest way to provide some measure of control, is to provide a I know that the docs say so, but when I tested in D7, that was not the case.An additional benefit that I’ll touch on briefly is access control.This hook allows you to specify what permissions a given path will require of the user.Enable the module, and go to /hello on your website. In the example below, this means the 0 will be turned into 'hello', as that's the first, and only, part of the URL. Often a URL argument will be the ID-number of something, such as an entity.

Then read the api documentation above, specifically the “access arguments” section. This hook will only be detected by Drupal inside of a module. Also, it’s important to know how to trigger this function, since Drupal only runs it rarely.

Perhaps the most popular, the Services Module, supports multiple formats including SOAP, JSON, REST, XMLRPC and AMF.

Services operates on predefined endpoints and can be extended with support from modules like the Services Views module and Services Rules module. Instead of providing endpoints it accepts HTTP header content type request and returns JSON or XML when requested.

If you have a need to expand your Drupal platform by programming a custom RESTful endpoint this post will help get you started.

The Drupal community has contributed several modules for processing RESTful POSTs.

In particular, you may want to read about permissions, as the page above will be viewable by .
