将回调应用于所有或特定请求数据

要求

• CakePHP 2.x

安装

将您的应用程序插件目录命名为 Datafilter。

启用插件

在 2.0 版本中，您需要在您的 app/Config/bootstrap.php 文件中启用插件

<?php
CakePlugin::load('Datafilter', array('bootstrap' => false, 'routes' => false));
?>

用法

在控制器中

<?php
App::uses('AppController', 'Controller');

class PostsController extends Controller {

	public $components = array('Datafilter.Datafilter');

	public function foo() {
		// Applies strtoupper() for all values
		/*
		$this->request->data looks like:
		Array
		(
			[Post] => Array
			(
				[key] => value
			)
		)
		*/

		$this->Datafilter->applyFilter('__ALL__', 'strtoupper');

		/*
		$this->request->data looks like:
		Array
		(
			[Post] => Array
			(
				[key] => VALUE
			)
		)
		*/
	}

	public function bar() {
		// Applies strtoupper() for specific field(s)
		/*
		$this->request->data looks like:
		Array
		(
			[Post] => Array
			(
				[key1] => value1
				[key2] => value2
			)
		)
		*/

		$this->Datafilter->applyFilter('Post.key1', 'strtoupper');

		/*
		$this->request->data looks like:
		Array
		(
			[Post] => Array
			(
				[key1] => VALUE1
				[key2] => value2
			)
		)
		*/
	}

	public function baz() {
		// Applies user function for specific field(s) with {}'s
		/*
		$this->request->data looks like:
		Array
		(
			[Post] => Array
			(
				[key1] =>  value1
			)
			[Tag] => Array
			(
				[0] => Array
				(
					[name] => value2
				)
				[1] => Array
				(
					[name] => value3
				)
			)
		)
		*/

		$this->Datafilter->applyFilter(array('Tag.{n}.name'), function($value) {
			return 'prefix_' . $value;
		});

		/*
		$this->request->data looks like:
		Array
		(
			[Post] => Array
			(
				[key1] => value1
			)
			[Tag] => Array
			(
				[0] => Array
				(
					[name] => prefix_value2
				)
				[1] => Array
				(
					[name] => prefix_value3
				)
			)
		)
		*/
	}
