使用setter注入的Zend ServiceManager

基于这个问题和您之前关于表单、字段集和输入过滤器的问题,我认为您希望实现类似于以下用例的功能。

用例

你有一个

• 位置实体
• 位置有一个到一个地址的one(必需的,单向的)

要管理位置,您需要:

• 位置形式(-工厂)
• LocationFieldset(-Factory)
• LocationFieldsetInputFilter(-Factory)
• AddressFieldsetInputFilter(-Factory)

要在ZF3中配置它,您必须添加以下内容

'form_elements' => [
    'factories' => [
        AddressFieldset::class  => AddressFieldsetFactory::class,
        LocationForm::class     => LocationFormFactory::class,
        LocationFieldset::class => LocationFieldsetFactory::class,
    ],
],
'input_filters' => [
    'factories' => [
        AddressFieldsetInputFilter::class  => AddressFieldsetInputFilterFactory::class,
        LocationFormInputFilter::class     => LocationFormInputFilterFactory::class,
        LocationFieldsetInputFilter::class => LocationFieldsetInputFilterFactory::class,
    ],
],

表格和;字段集

在 LocationForm ,添加您的 LocationFieldset 以及表单还需要什么,例如CSRF和submit按钮。

class LocationForm extends AbstractForm
{
    public function init()
    {
        $this->add([
            'name'    => 'location',
            'type'    => LocationFieldset::class,
            'options' => [
                'use_as_base_fieldset' => true,
            ],
        ]);

        //Call parent initializer. Adds CSRF & submit button
        parent::init();
    }
}

AbstractForm 多做一点,我建议你看看 here ,例如删除空(子字段集/集合)输入,以便不尝试在数据库中创建数据)

在 ,为位置提供add输入,例如名称和 AddressFieldset :

class LocationFieldset extends AbstractFieldset
{
    public function init()
    {
        parent::init();

        $this->add([
            'name'     => 'name',
            'required' => true,
            'type'     => Text::class,
            'options'  => [
                'label' => _('Name'),
            ],
        ]);

        $this->add([
            'type'     => AddressFieldset::class,
            'name'     => 'address',
            'required' => true,
            'options'  => [
                'use_as_base_fieldset' => false,
                'label'                => _('Address'),
            ],
        ]);
    }
}

在 地址字段集 只需为地址实体添加输入(同上,无字段集类型输入)

输入过滤器

class LocationFormInputFilter extends AbstractFormInputFilter
{
    /** @var LocationFieldsetInputFilter  */
    protected $locationFieldsetInputFilter;

    public function __construct(LocationFieldsetInputFilter $filter) 
    {
        $this->locationFieldsetInputFilter = $filter;

        parent::__construct();
    }

    public function init()
    {
        $this->add($this->locationFieldsetInputFilter, 'location');

        parent::init();
    }
}

(The) AbstractFormInputFilter 添加CSRF验证程序)

->add()

接下来是 LocationFieldsetInputFilter :

class LocationFieldsetInputFilter extends AbstractFieldsetInputFilter
{
    /**
     * @var AddressFieldsetInputFilter
     */
    protected $addressFieldsetInputFilter;

    public function __construct(AddressFieldsetInputFilter $addressFieldsetInputFilter) 
    {
        $this->addressFieldsetInputFilter = $addressFieldsetInputFilter;

        parent::__construct();
    }

    public function init()
    {
        parent::init();

        $this->add($this->addressFieldsetInputFilter, 'address'); // Again, name is important

        $this->add(
            [
                'name'       => 'name',
                'required'   => true,
                'filters'    => [
                    ['name' => StringTrim::class],
                    ['name' => StripTags::class],
                    [
                        'name'    => ToNull::class,
                        'options' => [
                            'type' => ToNull::TYPE_STRING,
                        ],
                    ],
                ],
                'validators' => [
                    [
                        'name'    => StringLength::class,
                        'options' => [
                            'min' => 3,
                            'max' => 255,
                        ],
                    ],
                ],
            ]
        );
    }
}

工厂

现在,你必须把它们绑在一起,我想这就是你关于塞特注射的问题。这是在工厂里发生的。

A. *FormFactory

public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
    $inputFilterPluginManager = $container->get('InputFilterManager');
    $inputFilter = $inputFilterPluginManager->get(LocationFormInputFilter::class);

    /** @var LocationForm $form */
    $form = new LocationForm();
    $form->setInputFilter($inputFilter); // The setter injection you're after

    return $form;
}

A. *FieldsetFactory 将执行以下操作(对Location和addressfieldset执行相同的操作):

public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
    /** @var LocationFieldset $fieldset */
    // name matters! Match the object to keep it simple. Name is used from Form to match the InputFilter (with same name!)
    $fieldset = new LocationFieldset('location'); 
    // Zend Reflection Hydrator, could easily be something else, such as DoctrineObject hydrator. 
    $fieldset->setHydrator(new Reflection()); 
    $fieldset->setObject(new Location());

    return $fieldset;
}

A. *FormInputFilterFactory

public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
    $inputFilterPluginManager = $container->get('InputFilterManager');

    /** @var LocationFieldsetInputFilter $locationFieldsetInputFilter */
    $locationFieldsetInputFilter = $inputFilterPluginManager->get(LocationFieldsetInputFilter::class);

    // Create Form InputFilter
    $locationFormInputFilter = new LocationFormInputFilter(
        $locationFieldsetInputFilter
    );

    return $locationFormInputFilter;
}

A. *FieldsetInputFilterFactory 将执行以下操作:

public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
    /** @var AddressFieldsetInputFilter $addressFieldsetInputFilter */
    $addressFieldsetInputFilter = $this->getInputFilterManager()->get(AddressFieldsetInputFilter::class);
    $addressFieldsetInputFilter->setRequired(true);

    return new LocationFieldsetInputFilter(
        $addressFieldsetInputFilter
    );
}

• 将InputFilter设置为(非)必需的是我添加的内容 here

我想我把这一切都说了一遍,以得到一个完整的画面。如果您对此有任何疑问,请发表评论。

你需要的是 初始值设定项 Zend Service Manager .

初始值设定项可以是在创建服务时调用的类。 在该类中,您需要检查所创建的服务的类型,以及它是否是合适的类型,而不是注入您想要的任何类型。

在配置下注册一个初始值设定项外接程序 密钥:

'service_manager' => [
    'initializers' => [
       MyInitializer::class
    ],
]

然后创建这个类

class MyInitializer implements InitializerInterface
{
    public function __invoke(ContainerInterface $container, $instance)
    {
        // you need to check should you inject or not
        if ($instance instanceof MessageGenerator) { 
            $instance->setLogger($container->get('logger'));
        }
    }
}

你需要注册 消息生成器 消息生成器 从SM,创建后调用MyInitializer。
