POSymfony2/Doctrine - Entity variable not returning an ArrayCollection object
text
Body
copied!<p>I have used ArrayCollections in my last project, which worked fine. Now in my new project, I am attempting to implement one, and it does NOT work completely even though I have done the same thing in both projects.</p> <p><strong>What works:</strong> I can add a new element in the ArrayCollection, and when I print out an overview of the object entity, I do get to see the elements I have put in, before and after persisting and flushing, in the same method.</p> <p><strong>What does NOT work:</strong> When I try to get the ArrayCollection from the entity, it returns nothing. When I do a getype($collection), I get null as well.</p> <p><strong>Code:</strong></p> <p>This is the code for both entities. Users is the entity that contains the ArrayCollection (emails), and Email is the entity I want to add into the ArrayCollection. Note that the inconsistency of the name of both entities was done on purpose.</p> <p><strong>Users.cpp (Entity)</strong></p> <pre><code><?php namespace HRPortal\SystemBundle\Entity; use Doctrine\ORM\Mapping as ORM; use Doctrine\Common\Collections\ArrayCollection; /** * Users * * @ORM\Table() * @ORM\Entity(repositoryClass="HRPortal\SystemBundle\Entity\UsersRepository") */ class Users { // ... /** * @var emails[] * * $ORM\OneToMany(targetEntity="Email", mappedBy="user", indexBy="id") */ private $emails; /** * Constructor for the class. Sets createdAt to Now * */ public function __construct() { // ... $this->emails = new ArrayCollection(); } /** * Get value for data '$name' * @param string $name * @return Type of data '$name' */ public function __get($name) { return $this->$name; } /** * Set value for data '$name' * @param string $name * @param generic $value * @return Type of data '$name' */ public function __set($name, $value) { $this->$name = $value; return $this; } public function offsetGet($name) { return $this->$name; } } </code></pre> <p><strong>Email.php (Entity)</strong></p> <pre><code><?php namespace HRPortal\SystemBundle\Entity; use Doctrine\ORM\Mapping as ORM; /** * Email * * @ORM\Table() * @ORM\Entity(repositoryClass="HRPortal\SystemBundle\Entity\EmailRepository") */ class Email { // ... /** * @var integer * * @ORM\ManyToOne(targetEntity="Users", inversedBy="emails") */ private $user; /** * @var string * * @ORM\Column(name="email", type="string", length=255) */ private $email; // ... } </code></pre> <p><strong>Part of the code from the controller</strong></p> <pre><code>$email = new Email(); $user->password = $bcrypt->hash($user->password); $user->emails->add($email); // print_r($user) will show data from $email (Emails Entity) $email->email = $form->get('email')->getData(); $email->is_default = true; $email->user = $user; $em->persist($email); $em->persist($user); $em->flush(); // print_r($user) will also show data from $email (of course) </code></pre> <p>However, when I try to access it later:</p> <pre><code>public function getDefaultEmail($user) { // print_r($user) will leave 'emails' empty but print out any other data // print_r($user->emails) will not show anything // Getting an error when accessing foreach, as $user->emails is null foreach ($user->emails as $email) { if($email->is_default === true){ return $email->email; } } return false; } </code></pre> <p>Any suggestions?</p> <p>Thank you</p>
