Creating a custom menu item Edit the module file again to make its content the following: Here is what mine looks like: Now the last thing you need to do is actually create that template.

Also, this file is not created yet, we will do that below. Otherwise it will simply be the value of the parameter. The page callback goes into a controller class.

Paths With Optional Arguments The above code will work correctly only for that specific path, with both parameters. In Drupal 7 the code might look like this: This post describes how to create custom pages on your drupal site, and create custom menu items page routeswithin a module.

Here is a reference page of permissions you may find useful. If you do not know how to create a basic custom module, check out our quick tutorial on the subject. But what if you wanted that path to display JSON instead?

The empty value says they are optional, or you could give them a fixed default value to be used if they are not present in the url. Save the files, flush all your Drupal caches, and visit your new path. You are also setting the default value for the parameters. For instance, the core nodeController manages four of the routes listed in node.

Most themes implement the page title as an H1 html tag. More information about this topic: This key-value pair determines who can see the new path and content, by providing an array of specific permissions a user must have.

Create the array of values you want to return and then return it as a JsonResponse object. There are various ways to control access: It finds the route it wants to alter using the alterRoutes method and changes it as necessary.

It does a little bit of everything: This is the name of your template implementation. Next, we need to create the callback function, since we named one up above.

For practice, we will be adding comments to almost all lines of code.

By adding the arguments to the defaults section you are telling the controller to treat the base path as the main route and the two additional parameters as path alternatives. There are two hooks we will be using in this exercise: Altering routes and creating dynamic routes are complicated topics that are really beyond the scope of this article.

This tutorial assumes you know how to create and upload files to your server using FTP, and also know how to create a basic custom module to use as a foundation. A controller can manage one or more routes, as long as each has a method for its callback and its own entry in the YAML file.

But things have changed In Drupal 8. Allow access by anyone to this path: See Symfony documentation for lots more information about configuring routes and route requirements.Feb 03,  · Drupal 7: hook_menu() Posted by jmm42 on 3 Feb at UTC The second function ' example_user_access() ' (two listed below) implements the ' hook_user_access() ' function.

The other day, I was trying to create a menu item with a dynamically generated path and hit a couple road blocks. After some reading I eventually worked it out and thought I would post an example here. In Drupal 7 that is done with hook_menu_alter, but that hook is also removed in Drupal 8.

It’s a little more complicated now. The simplest example in core I could find was in the Node module, which is altering a route created by the System module.

A path and its associated information is commonly called a "menu router item". This hook is rarely called (for example, when modules are enabled), and its results are cached in the database.

These are the hooks that are invoked by the Drupal core. Code function hook_menu. How should I implement hook_menu()? up vote down vote favorite. This information is valid for Drupal 6 and 7. In Drupal 8, hook_menu() has been replaced by new routing system.
