Symfony 4/5 Gedmo StofDoctrineExtensions Slugger (Custom slugger, regenerate slug)

Regenerate slug

https://github.com/doctrine-extensions/DoctrineExtensions/blob/main/doc/sluggable.md#regenerating-slug

• // That didn't work
  // $entity->setSlug(null);

Do it manually

• use Gedmo\Sluggable\Util\Urlizer;
  
              $slug = Urlizer::unaccent($entity->getName());
              $slug = Urlizer::urlize($slug);
              $entity->setSlug($slug);
  
              $em->persist($entity);
              $em->flush();

Use a custom slugger

• src/EventListener/GermanUmlautSluggableListener.php
  
  <?php
  
  namespace App\EventListener;
  
  use Gedmo\Sluggable\SluggableListener;
  use Gedmo\Sluggable\Util\Urlizer;
  
  /**
   * Create proper german umlaut slugs like Schlößer -> schloesser
   * @see https://github.com/Guite/MostGenerator/issues/241#issuecomment-22976742
   * @see https://github.com/doctrine-extensions/DoctrineExtensions/blob/main/doc/sluggable.md#custom-transliterator
   */
  class GermanUmlautSluggableListener extends SluggableListener

      public function __construct()
      {
          $callable = function($text, $separator = '-', $object) {
              $text = Urlizer::unaccent($text);
  
              return Urlizer::urlize($text, $separator);
          };
          $this->setTransliterator($callable);
      }
