I have set up a custom page with Panels.

In the Panel configuration I have set the page path to /products/%term.

I made a custom module which currently displays "Hello world" on this page, and all is well.

function product_tree_block_view($delta='') {
  $block = array();
  switch($delta) {
    case 'product_tree' :
      $block['content'] = theme('product_tree', array("greet" => "Hello world",));
  return $block;

However; I would like to process the %term to fetch some additional information, relevant only to the current %term.

My question is: How can I access the %term? Is this variable accessible from my module at all?


The function arg() will do that for you. For example, in path http://siteurl/products/%items,

  • arg(0) will have the value products (first value after your $base_url)
  • arg(1) will have the value of %items (second value).

You might then just apply your logic, in this this case you could do the check arg(1).

  • This is using showing the original url for me: /node/1222 – martinedwards Jan 12 '17 at 11:36

For Drupal 7 use arg() function and you are good to go.

For Drupal 8 follow below procedure,

Here's the example of accessing URL parameters and passing them to a TWIG template, I am considering you have already created your module and required files and suppose "/test?fn=admin" is your URL

  1. In Your .module file implement hook_theme and define variables and template name (Make sure you replace "_" with "-" when creating the template file)

     function my_module_theme () {   
             return [
              'your_template_name' => [               
                 'variables' => [
                     'first_name'    => NULL,

Now create your controller and put below code in it.

 namespace Drupal\my_module\Controller;

 use Drupal\Core\Controller\ControllerBase;
 use Symfony\Component\HttpFoundation\Request;

 class MyModule extends ControllerBase {

   public function content(Request $request) {

     return [
       '#theme' => 'my_template',
       '#first_name' => $request->query->get('fn'), //This is because the parameters are in $_GET, if you are accessing from $_POST then use "request" instead "query"


Now in your TWIG file which should be "my-template.html.twig" you can access this parameter as,

 <h3>First Name: {{ first_name }}</h3>

And its done. Hope this helps.
