One among Drupal Development Company nice issues about Drupal Development Company taxonomy phrases in has all the time been their hierarchical readiness. That’s, how they will simply be organised in a parent-child relationship by way of a easy drag-and-drop interface. This characteristic turns into much more vital in 8 the place creating entities for something you need has change into straightforward so we not should (ab)use taxonomy time period entities for every little thing. Except, in fact, we want this sort of behaviour. Nonetheless, I lately observed a shortcoming in Drupal Development Company approach we’re in a position to load taxonomy phrases programatically. I wanted to load a tree of phrases as represented by their hierarchy. However there isn’t any API (for Drupal Development Company second) that enables me to take action. Not less than none that I may discover. What I wanted was much like Drupal Development Company menu system the place in case you load a tree, you get an array of MenuLinkTreeElement objects that wrap Drupal Development Company hyperlinks and which might every comprise an array of MenuLinkTreeElement objects that signify Drupal Development Company youngsters (subtree) of that hyperlink. So one massive multidimensional array of objects. For phrases, I imaged there can be one thing related, however I used to be unsuitable. Drupal Development Service taxonomyTermStorage Drupal 10 Upkeep and Assist Service Drupal 10 Upkeep and Assist ServiceloadTree() methodology principally does half Drupal Development Company job I need. It returns all Drupal Development Company phrases in Drupal Development Company vocabulary, every represented as a stdClass object (why?) that comprises some primary information. And on this object we get a mother and father array that comprises Drupal Development Company IDs of Drupal Development Company phrases that are its mother and father (as you understand, phrases can have a number of mother and father). This can be sufficient in sure circumstances. Nonetheless, I wished to go one step additional. So I created a easy service that hundreds Drupal Development Company tree of a vocabulary in a multidimensional array, much like what Drupal Development Company menu system does Drupal 10 Upkeep and Assist Service <?php namespace taxonomy_tree; use CoreEntityEntityTypeManager; /** * Masses taxonomy phrases in a tree */ class TaxonomyTermTree { /** * @var CoreEntityEntityTypeManager */ protected $entityTypeManager; /** * TaxonomyTermTree constructor. * * @param CoreEntityEntityTypeManager $entityTypeManager */ public perform __construct(EntityTypeManager $entityTypeManager) { $this->entityTypeManager = $entityTypeManager; } /** * Masses Drupal Development Company tree of a vocabulary. * * @param string $vocabulary * Machine identify * * @return array */ public perform load($vocabulary) { $phrases = $this->entityTypeManager->getStorage(‘taxonomy_term’)->loadTree($vocabulary); $tree = []; foreach ($phrases as $tree_object) { $this->buildTree($tree, $tree_object, $vocabulary); } return $tree; } /** * Populates a tree array given a taxonomy time period tree object. * * @param $tree * @param $object * @param $vocabulary */ protected perform buildTree(&$tree, $object, $vocabulary) { if ($object->depth != 0) { return; } $tree[$object->tid] = $object; $tree[$object->tid]->youngsters = []; $object_children = &$tree[$object->tid]->youngsters; $youngsters = $this->entityTypeManager->getStorage(‘taxonomy_term’)->loadChildren($object->tid); if (!$youngsters) { return; } $child_tree_objects = $this->entityTypeManager->getStorage(‘taxonomy_term’)->loadTree($vocabulary, $object->tid); foreach ($youngsters as $little one) { foreach ($child_tree_objects as $child_tree_object) { if ($child_tree_object->tid == $child->id()) { $this->buildTree($object_children, $child_tree_object, $vocabulary); } } } } } No want to repeat it from right here, you will discover it on this repository inside a easy Drupal 10 module known as taxonomy_tree. So what I principally do right here is load Drupal Development Company default tree and iterate by all Drupal Development Company objects. If any of them will not be already at Drupal Development Company backside of Drupal Development Company tree, I populate a youngsters key with their youngsters. This occurs by utilizing Drupal Development Company TermStorage Drupal 10 Upkeep and Assist Service Drupal 10 Upkeep and Assist ServiceloadChildren() methodology and recursing by that record as properly. So let me know what you suppose and if this helps you out. Drupal 10 Growth and Assist
