如何在ZF3中触发Fieldset Factory [英] How to trigger fieldset factory in ZF3

问题描述

我需要使用工厂设置字段.我知道如何针对表单进行操作，但如何针对字段集进行操作?

I need to use factory for fieldset. I know how to do it for form, but how to do it for fieldset?

表单代码为:

namespace Application\Form;

use Application\Fieldset\Outline;
use Zend\Form\Element;
use Zend\Form\Form;

class Message extends Form
{
    public function __construct()
    {
        parent::__construct('message'); 
        $this->setAttribute('method', 'post');    
        $this->add([
            'type' => Outline::class,
            'options' => [
                'use_as_base_fieldset' => true,
            ],
        ]);
        $this->add([
            'name' => 'submit',
            'attributes' => [
                'type' => 'submit',
                'value' => 'Send',
            ],
        ]);
    }
}

如上所示，'type' => Outline::class, 行告诉解析器创建fieldset对象.但是如何告诉解析器使用自定义字段集工厂创建字段集对象?

As one can see above the line 'type' => Outline::class, tells parser to create fieldset object. But how to tell parser to create fieldset object with a custom fieldset factory?

推荐答案

FormElementManager是ServiceManager的扩展，因此您必须将其配置为与服务管理器相同.这是一个例子

FormElementManager is extending from ServiceManager so you have to config it same as service manager. Here's an example

class MyModule {
     function getConfig(){
           return [
               /* other configs */
               'form_elements' => [   // main config key for FormElementManager
                   'factories' => [
                        \Application\Fieldset\Outline::class => \Application\Fieldset\Factory\OutlineFactory::class
                   ]
               ]
               /* other configs */
           ];
     }
}

使用此配置，当您调用\Application\Fieldset\Outline::class时，\Application\Fieldset\Factory\OutlineFactory::class将由FormElementManager触发.一切与ServiceManager相同.您将通过服务管理器调用字段集；

With this config, when you call \Application\Fieldset\Outline::class, \Application\Fieldset\Factory\OutlineFactory::class will be triggered by FormElementManager. Everything same as ServiceManager. You will call your fieldset as via service manager;

$container->get('FormElementManager')->get(\Application\Fieldset\Outline::class);

您还可以通过getFormFactory方法在表单/字段集中对其进行调用；

Also you can call it in forms/fieldsets via getFormFactory method;

function init() { // can be construct method too, nothing wrong
   $this->getFormFactory()->getFormElementManager()->get(\Application\Fieldset\Outline::class);
}

当然，您可以在工厂支持的扩展名中使用它的名称.

And of course you can use it's name in your factory-backed form extensions.

但是，如果您通过new关键字创建它，则不会触发您的工厂.

BUT if you create it via new keyword, your factory will not be triggered.
