PHP Question

in_array() expects parameter 2 to be array, null given

I made a web-application with Symfony2, and I'm using PUGX User Bundle and FosUserBundle to manage 2 different users.

This is one of the two user:

/**
* @ORM\Entity
* @ORM\Table(name="user_Operator")
* @ORM\HasLifecycleCallbacks()
* @UniqueEntity(fields = "username", targetClass = "Acme\ManagementBundle\Entity\User", message="Username already_used")
* @UniqueEntity(fields = "email", targetClass = "Acme\ManagementBundle\Entity\User", message="Email already_used")
*/
class UserOperator extends User
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;

/**
* @ORM\PrePersist
*/
public function setCreatedAtValue()
{
$this->addRole('ROLE_OPERATOR');
}
}


When I try to register, I fill the form, submit, than appears:

Warning: in_array() expects parameter 2 to be array, null given in C:\BitNami\wampstack-
5.4.23-0\frameworks\symfony\vendor\friendsofsymfony\user-
bundle\FOS\UserBundle\Model\User.php line 142


The line 142 is the following:

135 public function addRole($role)
{
$role = strtoupper($role);
if ($role === static::ROLE_DEFAULT) {
return $this;
}

142 if (!in_array($role, $this->roles, true)) {
$this->roles[] = $role;
}

return $this;
}


Don't know because I have this problem since I made an association @ORM\ManyToMany between User and Mission, that is another entity that here doesn't appear. Before this I hadn't this problem.

I use PUGXUser Bundle because it helps to easily manage two different kind of user. The User Entity is in my bundle, extends FosUserBundle..../Model/User.php and is extended by UserOperator and UserGroundStation.

The definition of the role is in the FosUserBundle.../Model/User.php:

/**
* @var array
*/
protected $roles;


and the costruct is:

public function __construct()
{
$this->roles = array();
}

Answer

Try to use:

      if (is_array($this->roles)) {
          if (!in_array($role, $this->roles, true)) {
              $this->roles[] = $role;
          }
      }
