Fieldcollection

General Usage

Object field collections are predefined sets of data and layout fields, that can be added to objects at an arbitrary amount.

An object field collection is very similar to an object itself. It has a class or in this case field definition which needs to be made first, and then different field collection definitions can be used to add sets of fields to an object.

Fieldcollection Configuration

So with some restrictions you could say, a field collection is an object within an object.

When adding a field collection field to an object's class definition, the developer needs to specify the allowed field definition types for this field.

Fieldcollection Configuration

The user can then decide which and how many of the available field definitions shall be added to the object.

Fieldcollection Field

Data Storage

Field definition data is stored in a separate table for each field definition and object class. The naming convention for these tables is: object_collection_COLLECTION-NAME_OBJECT-ID. Such a table contains all the field data, the concrete object's id, field name and index of of the field collection within the field collection data field. In order to fully understand the data structure of objects and field collections, it is best to enter some example data and have a look at the tables created by Pimcore.

Working with PHP API

Of course, field collection data can be set programmatically as well. The following code snippet illustrates how this can be achieved. Let's say there is an object class collectiontest and a fieldcollection called *MyCollection. There is an object field called collectionitems which is of the type field collection.

$object = new DataObject\Collectiontest();
  
$object->setParentId(1);
$object->setUserOwner(1);
$object->setUserModification(1);
$object->setCreationDate(time());
$object->setKey(uniqid() . rand(10, 99));

$items = new DataObject\Fieldcollection();

for ($i = 0; $i < 5; $i++) {
    $item = new DataObject\Fieldcollection\Data\MyCollection();
    $item->setMyinput("This is a test " . $i);
    $items->add($item);
}

$object->setCollectionitems($items);
$object->save();

If you want to use localized fields inside field collections you have to set the object before calling any localized field - related methods.


...

$item = new DataObject\Fieldcollection\Data\MyCollection();
$item->setObject($object)
