Doctrine Utils

Doctrine Utils
Siteadmin 3 using Doctrine 2 as the ORM of choice. The doctrineUtils helper encapsulates a collection of functions that preform common operations with a doctrine entity. These operations range from converting an entity to an array to retrieving data store information about an entity.
Convert entity to array
1
doctrineUtils::getEntityArray(
2
    $entity,
3
    $includeAssociations,
4
    $useProxyIds,
5
    $associationConfiguration
6
);

Parameter
Type
Required
Description
$entity
Object
yes
The doctrine entity to be converted.
$includeAssociations
boolean
no
Default: false. If true, associated objects will be included in the converted array. For example, a user may have an association with posts. When converting the user object to an array, this flag must be set to true to include the user's posts. > Only in-memory associations will be included.
$useProxyIds
boolean
no
Default: false. If true, the real IDs of the base entity and associated entities will be replaced with UUIDs. The UUID Proxy documentation describes how to access content from these UUIDs.
$associationConfiguration
array
no
Default: []. A key/value map containing a list of entities that should be included in the object to array conversion. See association configuration guide for more information.
Association Configuration
The $associationConfiguration parameter in getEntityArray() is a map of entities which are allowed to be included in the object to array conversion process. This allows you to exclude unwanted data sets from the parsing process.
Example
1
<?php
2
class User {
3
    /** @var  int */
4
    protected $id;
5
    
6
    /** @var  string */
7
    protected $name;
8
    
9
    /** @var  Post[] */
10
    protected $posts;
11
    
12
    /** @var  User[] */
13
    protected $followers;
14
}
15
​
16
function parseUserAsArray(User $user) {
17
    $assocConf = array(
18
        'followers' => 'object'
19
    );
20
    
21
    return doctrineUtils::getEntityArray($user, true, false, $assocConf);
22
}
Copied!
The code snippet above will parse the user's id, name, and followers fields into an array. The posts property will be ignored, because it is not included in the association configuration.
Notice the association configuration is a key/value pair, where the key is the name of the associated entity, and the value is its type. The value will almost always be object.
Result
You may assume the user's ID is 12.
1
{
2
  "12": {
3
    "id": 12,
4
    "name": "John Doe",
5
    "followers": [
6
      <list of followers>
7
    ]
8
  }

}

Convert entity collection to array
1
doctrineUtils::getEntityCollectionArray(
2
    $collection,
3
    $includeAssociation,
4
    $associationConfiguration
5
);

$associationConfiguration
array
no
Default: []. A key/value map containing a list of entities that should be included in the object to array conversion. See association configuration guide for more information.

​
20
// Age is changed from 30 to 25.
21
// Nickname is skipped since the new value is null|0|false.
22
doctrineUtils::setEntityData($properties, $user);
23
​
24
// Age is changed from 30 to 25.
25
// Nickname is changed from 'Bobby' to null.
26
doctrineUtils::setEntityData($properties, $user, true);
27
​
28
// Create a new user object from property map.

$user2 = doctrineUtils::setEntityData($properties, new User(), true);
