Drupal 8 | Wrong alias used - drupal

Question

Bonjour,
I have a problem on Drupal 8 that I can't solve, that's why I'm calling on you.
I have 2 aliases for the same node :
/public/event/10
/pro/event/10
I have a block_1 that only appears on the " /public/* " pages and a block_2 on the " /pro/* " pages.
When I access to the url "/pro/event/10", block_1 is displayed and not block_2.
I conclude that Drupal selects the alias "/public/event/10" (probably the first one he finds) while I'm on the page "/pro/event/10".
How can I programmatically tell Drupal the right alias to use?
Thank you in advance for your help.

Answer 1

Here is the code if it can help someone
class OOutboundPathProcessor implements OutboundPathProcessorInterface
{
function processOutbound($path, &$options = [], Request $request = NULL, BubbleableMetadata $bubbleable_metadata = NULL)
{
// Only for nodes
if (!isset($options['entity_type']) OR $options['entity_type'] !== 'node')
{
return $path;
}
// Get current 'space'
$espace = \Drupal::service('session')->get('espace');
// Get the node to process
$node = $options['entity'];
// New path
$str_path = "/%s/%s/%s";
$new_path = sprintf($str_path, $espace, $node->bundle(), $node->id());
// Check new path
$isValid = \Drupal::service('path.validator')->isValid($new_path);
if ($isValid === true) return $new_path;
return $path;
}
}

You might want to create your own path_processor_outbound service by implementing OutboundPathProcessorInterface.
This implementation may work on /node/{id} paths if the current requests path matches /public/event/** or /pro/event/**.
Analyzing the node entity for it's type (bundle): If it is event generate and return your desired path; if it is not event don't manipulate the path and return the original.
Writing the actual implementation in PHP code may be your own pleasure ;-)
