php - 可捕获的 fatal error : Argument 1 passed to . .. 必须是...的实例，数组给定

Question

我想注册一个用户。在我的数据库中，我有一个表 user，其中有一个 FK player_id，在我的 players 表中，我有一个来 self 的团队表的 FK team_id。

这是我的 RegisterType 表单:

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';
    }
}

如您所见，我添加了指向另一个表单“PlayerType”的链接。这是我的 PlayerType 表单:

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';
    }
}

在我的 register.html.twig View 中，我有我所有的用户字段和我的玩家字段，如下所示:

<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">
        {{ form_widget(registerForm.player.playerLicensenumber,
        {"attr": {"class": "form-control"} }) }}
    </div>
    {% if not registerForm.player.playerLicensenumber.vars.valid %}
        <div class="col-sm-offset-3 col-sm-9 has-error">
            <h5><i class="glyphicon glyphicon-warning-sign"></i> <strong>Please fix:</strong></h5>
            {{ form_errors(registerForm.player.playerLicensenumber) }}
        </div>
    {% endif %}
</div>
<div class="form-group{{ registerForm.player.playerBirthyear.vars.valid ? '' : class_error }}">

    <div class="col-sm-9">
        {{ form_widget(registerForm.player.playerBirthyear,
        {"attr": {"class": "form-control"} }) }}
    </div>
    {% if not registerForm.player.playerBirthyear.vars.valid %}
        <div class="col-sm-offset-3 col-sm-9 has-error">
            <h5><i class="glyphicon glyphicon-warning-sign"></i> <strong>Please fix:</strong></h5>
            {{ form_errors(registerForm.player.playerBirthyear) }}
        </div>
    {% endif %}
</div>
<div class="form-group{{ registerForm.player.playerPosition.vars.valid ? '' : class_error }}">
    {{ form_label(registerForm.player.playerPosition, label|default(),
    { "label_attr": { "class": "col-sm-3 control-label"}}) }}
    <div class="col-sm-9">
        {{ form_widget(registerForm.player.playerPosition,
        {"attr": {"class": "form-control"} }) }}
    </div>
    {% if not registerForm.player.playerPosition.vars.valid %}
        <div class="col-sm-offset-3 col-sm-9 has-error">
            <h5><i class="glyphicon glyphicon-warning-sign"></i> <strong>Please fix:</strong></h5>
            {{ form_errors(registerForm.player.playerPosition) }}
        </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,
        {"attr": {"class": "form-control"} }) }}
    </div>
    {% if not registerForm.player.team.vars.valid %}
        <div class="col-sm-offset-3 col-sm-9 has-error">
            <h5><i class="glyphicon glyphicon-warning-sign"></i> <strong>Please fix:</strong></h5>
            {{ form_errors(registerForm.player.team) }}
        </div>
    {% endif %}
</div>

我现在的问题是当我想提交时出现以下错误:

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

更新:

609规则是这样的:

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

PropertyAccessor.php 中的规则 359、360

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

Answer 1

让我们将此错误分开，以便您了解如何找出错误消息。

ContextErrorException: Catchable Fatal Error: 

这是错误的类型。您可以编写错误处理程序来处理这些问题。

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

这意味着当调用 Users::setPlayer() 时，您必须在参数中使用 Player 对象来调用它。

array given, 

这意味着参数中没有 Player 对象，而是一个数组。

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

这会告诉您问题出在哪里:PropertyAccessor.php 的第 360 行。

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

这告诉您涉及 Users 类的哪一行。

因此，您所要做的就是将第 360 行的数组更改为 Player 对象。然后您可以继续处理下一个错误。

编辑:

因为第 360 行是从其他地方调用的，所以您必须向后追踪到调用第 360 行的任何内容。在这种情况下，正是这一行给您带来了问题:

$object->$setter($value);

$value 应该是一个 Player 对象，而不是一个数组。 $value 来自哪里？
