I'm trying to build a Drupal 8 module with a jQuery plugin. I wanted to pass some of the JavaScript variables to PHP so that I can save the variables into database.

This question asked about the way to do it in Drupal 7. Since hook_menu() is gone in Drupal 8, how can I accomplish this task?

Where you implemented hook_menu(), in Drupal 8 you need:

  • A .routing.yml file containing the routing definition

    example.name:
      path: '/example/{variable}'
      defaults:
        _controller: '\Drupal\example\Controller\ExampleController::content'
      requirements:
        _permission: 'access content'
    
  • A controller class for the page callback

    class ExampleController {  
      // ...
      public function content($variable) {
        // Do something with $variable.
      }
    }
    

What is important is the file structure, which should be as follows, assuming that example is the machine name of the module.

  • example
    The directory containing the module

    • example.routing.yml
    • src
      The directory containing all the classes

      • Controller (directory)

        • ExampleController.php
          The file containing the controller

Keep in mind that you can change the machine name of the module, the route name (example.name), and the name of the class implementing the controller (ExampleController); the ones I used are only examples.
