README
A mix of classes for improving the Collection.
Installation
composer require pion/laravel-support-collection
NestedObjectCollection
Creates a nested collection from flat collection to child nested collection based on parent property and id property.
It's expected that the values are objects, it will insert the childs into the desired property.
All childs are stored to childs property in the object. Can be empty.
You can call all Collection methods on the NestedObjectCollection object, all method calls are passed into the collection
Construct
Groups the items by the parent property and loops from the top of tree (null property or different value) and adds childs to the object.
Parameters
-
Collection
$items
-
string
$parentProperty
the property name to get the parent id -
string
$idProperty
the property name to get the id value -
string
$rootIndexKeyOnGroup
the index key for getting the root elements. When the parent property value returns null, it will be empty string. -
string
$propertyForChildren
the property name to store the childrenpublic function __construct(Collection $items, $parentProperty = "parent_id", $idProperty = "id", $rootIndexKeyOnGroup = "", $propertyForChildren = "childs")
Eloquent usage
It's advised to set a property in the Eloquent model to prevent creating childs into the attributes. For default property
name you can use the ChildsCollectionTrait
. This provides a public $childs
property for your Eloquent model
Example
$object1 = new stdClass();
$object1->id = 1;
// this is the root!
$object1->parent_id = null;
$object2 = new stdClass();
$object2->id = 2;
$object2->parent_id = 2;
$object3 = new stdClass();
$object3->id = 3;
$object3->parent_id = 1;
$example = new \Pion\Support\Collection\NestedObjectCollection(new \Illuminate\Support\Collection([
$object1, $object2, $object3
]));
$collection = $example->getCollection();
This example will create a collection of single item (the $object1
). This objects will have a new property $childs
which is holding a Collection of single item $object2
that holds again property $childs with a single item $object3
GroupedCollection
Enables a quick how to build a grouped collection. Just add a new item to the collection with given group key and the value. Optionally you can provide also the key for the value.
public function add($groupKey, $value, $key = null)
Example
The use of the collection is same as standard collection.
$groupedCollection = new GroupedCollection();
$groupedCollection->add("1", "test 1");
$groupedCollection->add("1", "test 2");
$groupedCollection->add("1", "test 3");
$groupedCollection->add("2", "test 2-1");
$groupedCollection->add("2", "test 2-2");
This will result in a collection of items with a collection object. If you export the collection into array you will grouped array as expected.
var_dump($groupedCollection->toArray());
array(2) {
[1] =>
array(3) {
[0] =>
string(6) "test 1"
[1] =>
string(6) "test 2"
[2] =>
string(6) "test 3"
}
[2] =>
array(2) {
[0] =>
string(8) "test 2-1"
[1] =>
string(8) "test 2-2"
}
}
