ZF2注册了无效的工厂 [英] ZF2 An Invalid Factory Was Registered

问题描述

我在ZF2应用程序中具有以下类和模块配置，并且出现以下错误:

I've the following classes and my module config in ZF2 application and it is giving the below error:

While attempting to create applicationformuserform(alias: Application\Form
\UserForm) an invalid factory was registered for this instance type.

UserFormFactory.php

<?php

namespace Application\Factory\Form;

use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
use Application\Form\UserForm;

class UserFormFactory implements FactoryInterface {

    public function createService(ServiceLocatorInterface $serviceLocator) {
        $services         = $serviceLocator->getServiceLocator();
        $entityManager    = $services->get('Doctrine\ORM\EntityManager');

        $form = new UserForm($entityManager);

        return $form;
    }
}

?>

UserForm.php

<?php

namespace Application\Form;

use Zend\Form\Form;
use Zend\InputFilter\InputFilterProviderInterface;
use Doctrine\ORM\EntityManager;

class UserForm extends Form implements InputFilterProviderInterface {

    protected $entityManager;

    public function __construct(EntityManager $entityManager) {
        parent::__construct();
        $this->entityManager = $entityManager;
    }

    public function init() {
        $this->add(array(
                'name' => 'username',
                'attributes' => array(
                        'type'  => 'text',
                ),
                'options' => array(
                        'label' => 'User Name',
                ),
        ));
        $this->add(array(
                'name' => 'first_name',
                'attributes' => array(
                        'type'  => 'text',
                ),
                'options' => array(
                        'label' => 'First Name',
                ),
        ));
        $this->add(array(
                'name' => 'last_name',
                'attributes' => array(
                        'type'  => 'text',
                ),
                'options' => array(
                        'label' => 'Last Name',
                ),
        ));
        $this->add(array(
                'name' => 'role_id',
                'type' => 'DoctrineModule\Form\Element\ObjectSelect',
                'options' => array(
                        'object_manager'     => $this->entityManager,
                        'target_class'       => 'Application\Entity\Role',
                        'property' => 'id',
                        'is_method' => true,
                        'find_method'        => array(
                                'name'   => 'getRoles',
                        ),
                        'label' => 'User Role',
                ),
        ));
    }

    public function getInputFilterSpecification() {
        return array(); // filter and validation here
    }
}

?>

Module.config.php

'form_elements' => array(
            'factories' => array(
                    'Application\Form\UserForm' => 'Application\Factory\Form\UserFormFactory',
            ),
    ),

我正在另一个控制器工厂中使用此表单工厂

And I'm using this form factory in another controller factory

UserControllerFactory.php

<?php

namespace Member\Factory\Controller;

use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
use Member\Controller\UserController;
use Application\Form\UserForm;

class UserControllerFactory implements FactoryInterface {

    public function createService(ServiceLocatorInterface $serviceLocator) {
        $services    = $serviceLocator->getServiceLocator();
        $userForm    = $services->get('FormElementManager')->get('Application\Form\UserForm');

        $controller  = new UserController($userForm);

        return $controller;
    }
}

?>

有人可以告诉我这可能是什么问题吗?

Could anybody tell me that what may be the issue?

推荐答案

一遍又一遍地查看代码后，我得到了自己的答案.实际上，我的 Factory 和 Form 文件夹不在 src 文件夹之外，这就是Zend找不到两个文件夹的所有类的原因.

I got my answer at my own after looking at the code again and again. Actually my Factory and Form folders were outside of src folder that's why Zend could not found all the classes of both folders.

我在src中同时移动了Factory和Form文件夹，现在可以正常工作了.

I moved both Factory and Form folder in src and now it's working fine.
