function commerce_theme_registry_alter in Commerce Core 7

Implements hook_theme_registry_alter().

The Entity API theme function template_preprocess_entity() assumes the presence of a path key in an entity URI array, which isn't strictly required by Drupal core itself. Until this is fixed in the Entity API code, we replace that function with a Commerce specific version.

@todo Remove when https://drupal.org/node/1934382 is resolved.

Defines features and functions common to the Commerce modules.

Code

function commerce_theme_registry_alter(&$theme_registry) {

  // Copy the preprocess functions array and remove the core preprocess function
  // along with the Entity API's and this module's.
  $functions = drupal_map_assoc($theme_registry['entity']['preprocess functions']);
  unset($functions['template_preprocess'], $functions['template_preprocess_entity'], $functions['commerce_preprocess_entity']);

  // Unshift the core preprocess function and the Commerce specific function so
  // they appear at the beginning of the array in the desired order.
  array_unshift($functions, 'template_preprocess', 'commerce_preprocess_entity');

  // Update the function list in the theme registry.
  $theme_registry['entity']['preprocess functions'] = array_values($functions);
