PHP Fatal Error

Question

I'm getting a PHP fatal error whenever I try to use taxonomy_term_save(). I am using it in an install script which may be pertinent information.

PHP Fatal error:  Class name must be a valid object or a string in /var/www/proface.com/includes/common.inc on line 7779, referer: http://domain/install.php?profile=company_install_profile&locale=en&op=start&id=1

Why would this happen? The terms look correct to me:

  $terms = array();

  drupal_load('module', 'taxonomy');
  $vocabulary = taxonomy_vocabulary_machine_name_load('distributor_types');

  $term = new stdClass();
  $term->name = "Platinum Distributors";
  $term->description = '';
  $term->vid = $vocabulary->vid;
  $term->weight = 0;
  $term->vocabulary_machine_name = 'distributor_types';
  $term->format = 'plain_text';
  $term->uuid = 'ee4e4f18-ad5e-46df-a2e7-145876efd907';
  $terms[] = $term;

Pulled out each of the terms from a foreach loop and...

  taxonomy_term_save($term);

And when I print out the entity name that is causing problems, it spits out, "taxonomy_vocabulary".

This is the function throwing the error, the line with "new $class($entity_type)" is line 7779.

function entity_get_controller($entity_type) {
  $controllers = &drupal_static(__FUNCTION__, array());
  if (!isset($controllers[$entity_type])) {
    $type_info = entity_get_info($entity_type);
    $class = $type_info['controller class'];
    $controllers[$entity_type] = new $class($entity_type);
  }
  return $controllers[$entity_type];
}

I believe the version for this is 7.22.

Answer 1

It's actually my coworker that should get credit for this, not me, but here's the solution:

drupal_load('module', 'taxonomy');

module_enable(array('taxonomy'), FALSE);

$vocabulary = taxonomy_vocabulary_machine_name_load('distributor_types');

The taxonomy module wasn't enabled.

My working theory right now is that as of that point in your code Drupal isn't aware of the taxonomy_vocabulary controller. You could try running entity_get_info('taxonomy_vocabulary') first to inform Drupal of the taxonomy_vocabulary controller.
