Act on entities when inserted.
$entity: The entity object.
$type: The type of entity being inserted (i.e. node, user, comment).
Note: this list is generated by pattern matching, so it may include some functions that are not actually implementations of this hook.
function hook_entity_insert($entity, $type) {
// Insert the new entity into a fictional table of all entities.
$info = entity_get_info($type);
list($id) = entity_extract_ids($type, $entity);
db_insert('example_entity')
->fields(array(
'type' => $type,
'id' => $id,
'created' => REQUEST_TIME,
'updated' => REQUEST_TIME,
))
->execute();
