Field Collection Value field is not deleting correctly(using programmatically)

Question

I installed the Field ollection module in a Drupal 7 site and I added a multi-field (unlimited) field collection with three items.

I need to programmatically delete the field collection.

I used the following code, which does not work.

$field_collection_delete = $node->field_accommodation['und'][$j]['value']; 
entity_delete_multiple('field_collection_item', array($field_collection_delete));

The value in the field collection item is deleted from the database, but the field collection field I added in the content type is still in the database.

I need to delete that too.

What code do I need to use to make it happen?

Answer 1

You need to unset the field from node first!

unset($node->field_accommodation['und'][$j]);

Answer 2

You should delete field collections by calling $field_collection->delete(); This handles a few other things for you such as deleting the parent entity.
