How to get taxonomy term field values

Question

I have created vocabulary "Hospital" and created text and image fields like:

• Hospital Image: (machine name: field_hospital_image) // image field
• Hospital Contact: (machine name: field_hospital_contact_no_) // text field

My code is:

$vid = 'hospitals';
$terms = \Drupal::entityTypeManager()->getStorage('taxonomy_term')->loadTree($vid);
foreach ($terms as $term) {
  $term_data[] = [
    'tid' => $term->tid,
    'tname' => $term->name,
    'image' => ...???..,    // image field
    'contact' => ...???..,  // text field
  ];
}

Please suggest namespace also.

I alsready tried :

'contact' => $term->get('field_hospital_contact_no_')->getValue(),

and

'contact' => $term->get('field_hospital_contact_no_')->value,

Errors:

Error: Call to undefined method stdClass::get()

Term object is not loaded with loadTree by default a basic php object is loaded instead.

You have to load the term object for each term using $term_obj = Drupal::entityTypeManager()->getStorage('taxonomy_term')->load($term->tid);

Your code should look like this

$vid = 'hospital';
$terms = \Drupal::entityTypeManager()->getStorage('taxonomy_term')->loadTree($vid);
foreach ($terms as $term) {
  $term_obj = Drupal::entityTypeManager()->getStorage('taxonomy_term')->load($term->tid);
  $url = "";
  if(isset($term_obj->get('field_hospital_image')->entity)){
    $url = file_create_url($term_obj->get('field_hospital_image')->entity->getFileUri());
  }

  $term_data[] = [
    'tid' => $term->tid,
    'tname' => $term->name,
    'contact' => $term_obj->get('field_hospital_contact_no_')->value,
    'image_url' => $url,
  ];
} 

NOTE: Alternatively you can also use loadTree($vid, 0, NULL, TRUE) to load the entities directly on the $terms array but perhaps it should be avoided on very large vocabularies. More info on the loadTree method
