1，main.php 里面导入
'import' => array(
'application.components.*'
),
2，application/components/BaseComponent.php
<?php
/**
* 基础组件
*/
class BaseComponent extends CComponent
{
public function init()
{
}
}
3,application/components/TestComponent.php
<?php
class TestComponent extends BaseComponent {
public $title = 'aaxx';
private $_url = 'ccdd';
//这里的get方法和set方法写了之后就可以直接调用私有属性！如果不允许直接调用则去掉这两个方法
public function setUrl($value='') {
$this->_url = $value;
}
public function getUrl() {
return $this->_url ;
}
public function test()
{
return 'test';
}
}
4，application/components/Controller.php
class Controller extends CController
{
public function init()
{
header('Content-type:text/html;charset=utf-8');
}
/**
* __get()
* @see CComponent::__get()
*/
public function __get($name)
{
if(substr(strtolower($name), -4) == 'comp') {
return $this->getComponent($name);
} else if(isset($this->default_tpl_vars[$name])) {
return $this->default_tpl_vars[$name];
}
return parent::__get($name);
}
/**
* @desc 获取组件
* @author lijianwei
*/
public function getComponent($name)
{
$name = strtolower($name);
$component_id = substr($name, 0, -4);
$component_class_name = ucfirst($component_id). 'Component';
if(Yii::app()->hasComponent($component_id)) {
return Yii::app()->getComponent($component_id);
} else {
Yii::app()->setComponent($component_id, array('class' => $component_class_name));
return Yii::app()->getComponent($component_id);
}
}
}
5，控制器调用application/Controllers/HomeController.php
class HomeController extends Controller
{
public function actionIndex()
{
$b = $this->testComp->url='ddd';//因为有set方法，给组件私有变量赋值不报错
echo $b;
echo $this->testComp->test();
}
}
