I have a module where I created a route /page/tag/{term} that uses a controller for modifications to how the term page is handled.

The problem is that when any page displays these term links, they don’t use the custom route, but the default /taxonomy/term/{id}.

How can I tell the taxonomy term links to use my custom route?

Adding the path as the term alias skips over the custom route entirely.

OR, how would I get rid of the custom route and create a pathauto pattern using the same path, but tell those pages to use my custom controller?

I have tried both methods without success…

Here is what I’ve tried with modifying the existing route:

modulename.services.yml

services:   modulename.route_subscriber:     class: DrupalmodulenameRoutingRouteSubscriber     tags:       - { name: event_subscriber, priority: 100 } 

modulename/src/Routing/RouteSubscriber.php

namespace DrupalmodulenameRouting;  use DrupalCoreRoutingRouteSubscriberBase; use SymfonyComponentRoutingRouteCollection;  /**  * Listens to the dynamic route events.  */ class RouteSubscriber extends RouteSubscriberBase {      /**     * {@inheritdoc}     */     protected function alterRoutes(RouteCollection $collection) {         if ($route = $collection->get('entity.taxonomy_term.canonical')) {             // i've tried both of these             $route->addDefaults(['_controller' => 'DrupalmodulenameControllerListController::list_by_tag' ']);             $route->addDefaults(['_title' => 'test']);         }     }  } 

Edit: after seeing this, I thought about keeping my custom route and using the alterRoutes to change the links…

$route->setPath('/page/tag');

That worked, but it adds on ?taxonomy_term=123

How can I get the term name into the url? /page/tag/term

Update:

Still can’t figure out how to get the term name from the route (without loading the taxonomy entity – I’d imagine that is too much load)

Also, I will need to make sure I’m in a specific vocabulary before changing the route.

Any ideas?
