Please document field collection hooks in field_collection.api.php

/me nods

I concur.

trying to figure out how field_collections render their output so I can alter it slightly before display, and I can't find where to hook in.

are there any hooks for field_collections? or should i just start hacking the module...?

Actually, field_collection has no hooks or alters of its own.

Both the field collection and the field collection items are fields, so they are subject to the hooks of the Field API.

For example, if I have a content type named 'tour' with a field collection named 'field_tour_date', and I want to change the name of the 'edit' link, here is code you could use. (This uses hook_field_attach_view_alter().)

/**
 * Implements hook_field_attach_view_alter().
 */
function MYMODULE_field_attach_view_alter(&$output, $context) {
  $content_type = 'tour';
  $field_name = 'field_tour_date';

  if ($context['entity_type'] == 'node' && $context['entity']->type == $content_type) {
    foreach (element_children($output[$field_name]) as $delta) {
      if (isset($output[$field_name][$delta]['links']['#links']['edit'])) {
        $output[$field_name][$delta]['links']['#links']['edit']['title'] = t('Click here to edit');
      }
    }
  }
}

Obviously you could just change the edit text in the UI, but you could have certain cases you wanted to change it.

And I would have gotten away with it if it weren't for that meddling Dave Reid!

I forgot that Entity API provides hooks for every module that integrates with it.

• hook_field_collection_item_load()
• hook_field_collection_item_insert()
• hook_field_collection_item_presave()
• hook_field_collection_item_update()
• hook_field_collection_item_delete()
• hook_field_collection_item_view()
• hook_field_collection_item_view_alter()

Most of this can be copied straight from http://drupalcode.org/project/profile2.git/blob/refs/heads/7.x-1.x:/prof...

The documentation for these functions was added to field_collection.api.php somewhere along the way.
