Drupal 8 - taxonomy_get_children()

Introduction

The taxonomy_get_children() function is used to retrieve the child terms of a given term ID from a specific taxonomy vocabulary in Drupal 8. This function returns an array of term IDs of the child terms, sorted by weight.

Syntax

taxonomy_get_children($term_id, $vid)

• $term_id (required): The term ID of the parent term.
• $vid (required): The vocabulary ID of the taxonomy.

Example Usage

$term_id = 5; // Parent term ID
$vid = 'categories'; // Taxonomy vocabulary ID

$child_terms = taxonomy_get_children($term_id, $vid);

foreach ($child_terms as $child) {
  // Process child terms
}

In this example usage, we retrieve the child terms of a parent term with the term ID 5 from a taxonomy vocabulary with the ID categories. We then loop through the child terms and process them accordingly.

Conclusion

The taxonomy_get_children() function in Drupal 8 is a useful tool for retrieving child terms of a specific parent term in a given taxonomy vocabulary. This function can be useful for building complex taxonomy-driven applications on the Drupal 8 platform.
