A different template based on a taxonomy term in views

Question

I'm using drupal 8.

I use the view provided by default: "taxonomy term".

I would like to make a presentation of the page (and not only of the node) different according to the term of taxonomy.

I tried with this code (in .theme) and template suggestion :

use Drupal\taxonomy\Entity\Term;

function THEME_NAME_theme_suggestions_page_alter(&$suggestions, &$vars) {
  if (\Drupal::routeMatch()->getRouteName() == 'entity.taxonomy_term.canonical' && $tid = \Drupal::routeMatch()->getRawParameter('taxonomy_term')) {
    $term = Term::load($tid);
    $suggestions[] = 'page__taxonomy__' . $term->getVocabularyId();
  }
}

But it does not work because (i think) it is a view.

I tried with the views template suggestion but it works only for the whole page and not for each taxonomy term.

Does anyone have the solution ?

Answer 1

You can define each template by using template page--taxonomy--term--xxx.html.twig where xxx is your term id.

In your code, $term->getVocabularyId(); will return machine name of vocabulary, not the term id. It mean all term of this vocabulary will use this template.

Answer 2

If you are looking to add suggestions based on the name of each term then you may add as below

use Drupal\taxonomy\Entity\Term;

function THEME_NAME_theme_suggestions_page_alter(&$suggestions, &$vars) {
  if (\Drupal::routeMatch()->getRouteName() == 'entity.taxonomy_term.canonical' && $tid = \Drupal::routeMatch()->getRawParameter('taxonomy_term')) {
    $term = Term::load($tid);
    $suggestions[] = 'page__taxonomy__' . $term->getVocabularyId();
    // To add suggestions based on route name
    $suggestions[] = 'page__taxonomy__term__' . strtolower(str_replace(' ', '_', $term->getName()));
  }
}
