Question

我无法理解工厂的实际运作方式。我准备了短文件来测试它的表单元素。

Application / config / module.config.php

<?php
namespace Application;

use Zend\Router\Http\Literal;
use Zend\Router\Http\Segment;
use Zend\ServiceManager\Factory\InvokableFactory;
use Application\Route\StaticRoute;
use Doctrine\ORM\Mapping\Driver\AnnotationDriver;
use Application\Form\Factory\AbcFormFactory;
use Application\Form\AbcForm;

return [
    'form_elements' => [
        'factories' => [
            AbcForm::class => AbcFormFactory::class,
        ],
    ],
//(...)
];

Application / src / Form / Factory / AbcFormFactory.php

<?php

namespace Application\Form\Factory;

use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
use Application\Form\AbcForm;

class AbcFormFactory implements FactoryInterface
{
    public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
    {
        return new AbcForm("It works");
    }
}

应用/ SRC /窗体/ AbcForm.php

<?php

namespace Application\Form;

use Zend\Form\Element;
use Zend\Form\Form;
use Zend\Hydrator\ClassMethods as ClassMethodsHydrator;
use Zend\InputFilter\InputFilter;

class AbcForm extends Form
{

    public function __construct($letter='no factory')
    {
        die($letter);
    }
}

上面的代码显示no factory，因此忽略工厂。如果没有被忽略，它将显示It works。

如何为form_elements创建合适的工厂？

更新我在控制器中调用表单：

<?php

namespace Application\Controller;

use Application\Form\AbcForm;
use Zend\Mvc\Controller\AbstractActionController;

class AbcController extends AbstractActionController
{
    public function indexAction()
    {
        $form = new AbcForm();
    }
}

什么触发器形成工厂__invoke方法？我认为，当通过 new 实现表单类时，应该运行表单工厂__invoke方法。或者不是？

在ZF3的module.config.php中忽略form_elements键
