将表单作为嵌套工厂创建

+- IFormFactory ---+    +- IFormFactory --+    +- IFormFactory -+
|   Base factory   | -> |   Adds inputs   | -> |  Adds mapping  | -> create() : Form
+------------------+    +-----------------+    +----------------+

优势

• 在一个地方更改整个应用程序的表单配置。
• 每个工厂都可以独立使用。
• 不需要继承表单。

安装

使用 Composer 安装 Venne/Forms 是最佳方式

composer require venne/forms:@dev

使用方法

创建基本工厂

示例

services:
	basicFormFactory:
		class: Nette\Application\UI\Form
		arguments: [NULL, NULL]
		implement: Venne\Forms\IFormFactory
		setup:
			- setRenderer(@system.formRenderer)
			- setTranslator(@translator.translator)
		autowired: no

将表单作为工厂创建

实现 Venne\Forms\IFormFactory

class FooFormFactory implements Venne\Forms\IFormFactory
{

	private $formFactory;


	public function __construct(IFormFactory $formFactory)
	{
		$this->formFactory = $formFactory;
	}


	public function create()
	{
		$form = $this->formFactory->create();
		$form->addText('foo', 'Foo');
		$form->addSubmit('_submit', 'Save');
		return $form;
	}

}

注册表单

在构造函数中定义嵌套表单工厂

services:
	fooFormFactory:
		class: FooFormFactory(@basicFormFactory)

在表示器中使用它

class ExamplePresenter extends Nette\Application\UI\Presenter
{

	private $fooFormFactory;

	public function __construct(FooFormFactory $fooFormFactory)
	{
		$this->fooFormFactory = $fooFormFactory;
	}

	public function createComponentFooForm()
	{
		$form = $this->fooFormFactory->create();
		$form->onSuccess[] = $this->fooFormSuccess;
		return $form;
	}

	public function fooFormSuccess($form)
	{
		...
	}

}

通过 kdyby\doctrine-forms 连接表单

use Venne\Bridges\Kdyby\DoctrineForms\FormFactoryFactory;

class ExamplePresenter extends Nette\Application\UI\Presenter
{

	private $fooFormFactory;
	private $formFactoryFactory;

	public function __construct(FooFormFactory $fooFormFactory, FormFactoryFactory $formFactoryFactory)
	{
		$this->fooFormFactory = $fooFormFactory;
		$this->formFactoryFactory = $formFactoryFactory;
	}

	public function createComponentFooForm()
	{
		$entity = ....;

		$form = $this->formFactoryFactory
					->create($this->fooFormFactory)
					->setEntity($entity)
					->create();

		$form->onSuccess[] = $this->fooFormSuccess;
		return $form;
	}

	public function fooFormSuccess($form)
	{
		...
	}

}
