Php – Catchable Fatal Error: Argument 1 passed to “…\FormType::__construct() must implement interface

doctrine-ormPHPsymfony

I am trying to call entityManager in formType. I don't get why this is not working.

FormType :

private $manager;

public function __construct(ObjectManager $manager)
{
    $this->manager = $manager;
}

Controller:

$form = $this->createForm(ProductsType::class, $products);

Services:

apx.form.type.product:
    class: ApxDev\UsersBundle\Form\ProductType
    arguments: ["@doctrine.orm.entity_manager"]
    tags:
        - { name: form.type }

Error:

Catchable Fatal Error: Argument 1 passed to MyBundle\Form\FormType::__construct() must implement interface Doctrine\Common\Persistence\ObjectManager, none given, called in vendor/symfony/symfony/src/Symfony/Component/Form/FormRegistry.php on line 90 and defined

Assuming your services.yml file is being loaded and that you copied pasted in the contents then you have a simple typo:

# services.yml
class: ApxDev\UsersBundle\Form\ProductType
should be
class: ApxDev\UsersBundle\Form\ProductsType

Php – Symfony2: ContextErrorException: Catchable Fatal Error: Argument 1 passed to […]::__construct() must implement interface […] none given

PL\OrderBundle\Entity\OrderHasComment's constructor asks for a mandatory argument but don't you provide it when you create a new instance of the object.

You're creating a new OrderHasComment (whatever that is) like this:

$object = new OrderHasComment() // <- missing argument

Remove that - it won't be needed anymore once your listener calls something like setContext(...) and it's not needed to create the object ... so it shouldn't be mandatory anyways.

// remove the mandatory argument or provide a default (i.e. $context = null)
public function __construct(ContextInterface $context) /
{
    // ...

... should become:

public function __construct()
{

This solves the issue that's responsible for the exception.

Php – Catchable Fatal Error: Argument 4 passed to UsernamePasswordToken::__construct() must be an array, null given

Basically, what the error message says is:

The 4th argument for UsernamePasswordToken::__construct() should be an array, but it's null. It was called in UserAuthenticationProvider at line 96.

If you take a look at that code, you'll see that the 4th argument for UsernamePasswordToken::__construct() is $roles. So that should be an array, but it's getting null instead.

I'm guessing that you have written your own User entity, and that the getRoles() method of your user entity is returning null instead of an array of roles. So just change that method to something like this:

/**
 * Returns the roles granted to the user.
 * 
 * @return Role[] The user roles
 */
public function getRoles()
{
    return array('ROLE_USER');
}

Of course, the actual code may differ (you might want to store the user roles in the database), as long as getRoles() returns an array of strings or Role objects.
