I wonder if there is a good, and easy way to get all fields of an entity.
I have a taxonomy vocabulary. Its terms have a special field I want to make list in a select box in one of my modules, so that users can select a special value of the term. Therefore, I need a way to list the possible fields for this term.
The function you are looking for is field_info_instances().
Retrieves information about field instances.
Drupal 7
You may try:
$info = entity_get_property_info($entity_type);
$info += array(
'properties' => array(),
'bundles' => array(),
);
// Add all bundle properties.
foreach ($info['bundles'] as $bundle => $bundle_info) {
$bundle_info += array('properties' => array());
$info['properties'] += $bundle_info['properties'];
}
var_dump($info['properties']);
Or if you have Entity module installed, then try:
entity_get_all_property_info('node');
Drush commands (one of these):
drush eval "var_dump(entity_get_all_property_info('node'));"
drush eval "print var_export(array_keys(entity_get_all_property_info('node')));"
Can also use the function : field_info_field_map()
In place of returning entities going down to fields, it starts from field and go down to entities. That second one is fine to see where fields are going, whereas field_info_instances() shows how entities are built.
