Catchable Fatal Error: Argument 1 passed to ... must be an instance of ..., array given

Question

I want to register a user. In my database I have a table user with a FK player_id and in my players table I have a FK team_id from my team table.

This is my RegisterType Form:

class RegisterType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('userFirstname', 'text', [
                'label' => 'Given name*',
                'attr'  => [
                    'placeholder' => 'Enter your given name.',
                ],
            ])
            ->add('userSurname', 'text', [
                'label' => 'Family name*',
                'attr'  => ['placeholder' => 'Enter your family name.'],
            ])
            ->add('userType', 'choice', array(
                'choices' => array('E' => 'ENTHOUSIAST', 'P' => 'PLAYER', 'T' => 'TRAINER'),
                'label'   => 'User Type*',
                'attr' => array('placeholder' => 'User Type')
            ))
            ->add('player', new PlayerType())
            ->add('userUsername', 'text', [
                'label' => 'Username*',
                'attr'  => ['placeholder' => 'Enter a username.'],
            ])
            ->add('userEmail', 'email', [
                'label' => 'Email address*',
                'attr'  => ['placeholder' => 'Enter your email address.'],
            ])
            ->add('userPassword', 'repeated', [
                'type'           => 'password',
                'first_name'     => 'password',
                'first_options'  => [
                    'label' => 'Password*',
                    'attr'  => ['placeholder' => 'Enter a password.'],
                ],
                'second_name'    => 'confirm',
                'second_options' => [
                    'label' => 'Password (repeat)*',
                    'attr'  => ['placeholder' => 'Repeat the password.'],
                ],
                'invalid_message' => 'The passwords are not identical.',
            ])
            ->add('btn_register', 'submit', [
                'label' => 'Register',
            ])
        ;
    }

    /**
     * @return string
     */
    public function getName()
    {
        return 'register';
    }
}

As you can see I've added a link to another form 'PlayerType'. This is my PlayerType Form:

class PlayerType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('playerLicensenumber', 'text', [
                'label' => 'Your License number*',
                'attr'  => ['placeholder' => 'Enter your license number.'],
            ])
            ->add('playerPosition', 'choice', array(
                'choices' => array('T' => 'Trainer', 'S' => 'Spelverdeler', 'R' => 'Receptie/Hoek', 'L' => 'Libero', 'M' => 'Midden', 'O' => 'Opposite', 'A' => 'All-round'),
                'label'         => 'Position you play at*',
                'attr' => array('placeholder' => 'Enter your play position.')
            ))
            ->add('playerBirthyear', 'text', array(
                'label' => 'Your Birth Year',
                'attr'  => ['placeholder' => 'Enter your birth year.'],
                'required' => false
            ))
            ->add('team', 'text', array(
                'label' => 'You play with*',
                'attr'  => ['placeholder' => 'Enter your team.']
            ))
        ;
    }

    /**
     * @return string
     */
    public function getName()
    {
        return 'player';
    }
}

And in my register.html.twig view I have all my user fields an my player fields like this:

<div class="form-group{{ registerForm.player.playerLicensenumber.vars.valid ? '' : class_error }}">
    {{ form_label(registerForm.player.playerLicensenumber, label|default(),
    { "label_attr": { "class": "col-sm-3 control-label"}}) }}
    <div class="col-sm-9">

    {% if not registerForm.player.playerLicensenumber.vars.valid %}
        <div class="col-sm-offset-3 col-sm-9 has-error">

        </div>
    {% endif %}
</div>
<div class="form-group{{ registerForm.player.team.vars.valid ? '' : class_error }}">
    {{ form_label(registerForm.player.team, label|default(),
    { "label_attr": { "class": "col-sm-3 control-label"}}) }}
    <div class="col-sm-9">
        {{ form_widget(registerForm.player.team,

    </div>

            {{ form_errors(registerForm.player.team) }}
        </div>
    {% endif %}
</div>

My problem is now when I want to submit I get the following error:

ContextErrorException: Catchable Fatal Error: Argument 1 passed to VolleyScout\VolleyScoutBundle\Entity\Users::setPlayer() must be an instance of VolleyScout\VolleyScoutBundle\Entity\Players, array given, called in /Applications/mampstack-5.4.20-0/apache2/htdocs/volleyscout/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php on line 360 and defined in /Applications/mampstack-5.4.20-0/apache2/htdocs/volleyscout/src/VolleyScout/VolleyScoutBundle/Entity/Users.php line 609

UPDATE:

The 609 rule is this:

public function setPlayer(\VolleyScout\VolleyScoutBundle\Entity\Players $player){
    $this->player = $player;
}

Rule 359, 360 in PropertyAccessor.php

if ($reflClass->hasMethod($setter) && $reflClass->getMethod($setter)->isPublic()) {
        $object->$setter($value);

Answer 1

Let's take this error apart so you can see how to figure out error messages.

ContextErrorException: Catchable Fatal Error: 

This is the type of the error. You can write an error handler to handle these.

Argument 1 passed to VolleyScout\VolleyScoutBundle\Entity\Users::setPlayer() 
must be an instance of VolleyScout\VolleyScoutBundle\Entity\Players, 

This means that when Users::setPlayer() is called, you have to call it using a Player object in the argument.

array given, 

This means that instead of a Player object, there was an array in the argument.

called in /Applications/mampstack-5.4.20-0/apache2/htdocs/volleyscout/vendor
/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php 
on line 360

This tells you where the problem is: line 360 of PropertyAccessor.php.

and defined in /Applications/mampstack-5.4.20-0/apache2/htdocs/volleyscout
/src/VolleyScout/VolleyScoutBundle/Entity/Users.php line 609

This tells you what line of the class Users is involved.

So, all you have to do is change that array on line 360 to a Player object. Then you can move on to the next error.

EDIT:

Because line 360 is being called from somewhere else, you'll have to trace backwards to whatever was calling line 360. In this case, it's this line that's giving you an issue:

$object->$setter($value);

The $value is supposed to be a Player object, not an array. Where is $value coming from?
