Create taxonomy terms from content type field

Question

I'm looking to add a taxonomy term to a vocabulary upon the creation of content type.

For example I have a taxonomy vocabulary called "Widget Type".

I have a content type of Product. When I create an instance of product I would like the title (product.title_1) to be added as a taxonomy term to Widget Type.

Then every time a new product is created a term is added. Widget Type would then contain the terms... title_1 title_2...etc.

Does this require a custom module or is there an easier way to do this that I'm not aware of?

Thanks

You can trigger this behavior by implementing the hook_entity_presave on a custom module. Inside of this hook, you will call a function which creates each time the taxonomy term using the title of the node created. Here is my example:

File: test.module

use Drupal\Core\Entity\EntityInterface;

/** * Implements hook_entity_presave(). */ function test_entity_presave(EntityInterface $entity) { if ($entity->bundle() == 'product') { if ($entity->isNew()) { $title = $entity->get('title')->getValue(); \Drupal\test\Test::createTerm($title[0]['value']); } } }

Assuming you have defined the createTerm function into Class Test:

File Test.php(Include this file in src folder)

namespace Drupal\test;

/** * Test class. */ class Test { public static function createTerm($title) { $term = [ 'name' => $title, 'vid' => 'widget_type', 'langcode' => 'en', ]; $term = \Drupal::entityTypeManager()->getStorage('taxonomy_term')->create($term); $term->save(); } }
