这篇文章主要介绍了yii中widget的用法,实例分析了widget在视图中的调用方法以及定义方法,具有一定的参考借鉴价值,需要的朋友可以参考下

本文实例讲述了yii中widget的用法。分享给大家供大家参考。具体分析如下:

WIDGET定义很简单,如果你在/protected/widget/test/下建立了一个名为“testWidget.php”的widget。

在视图中调用需要这样写:

复制代码 代码如下:

$this->beginWidget('application.widget.test.testWidget');
?>
//...可能小部件需要用到这里主体内容...
$this->endWidget();
?>


testWidget.php文件的定义方式:

复制代码 代码如下:

/**
* test widget
*/
class testWidget extends CWidget
{   
    public function init()
    {
        //当视图中执行$this->beginWidget()时候会执行这个方法
        //可以在这里进行查询数据操作
    }
 
    public function run()
    {
        //当视图中执行$this->endWidget()的时候会执行这个方法
        //可以在这里进行渲染试图的操作,,注意这里提到的视图是widget的视图
        //注意widget的视图是放在跟widget同级的views目录下面,例如下面的视图会放置在
        //  /protected/widget/test/views/test.php
        $this->render('test', array(
            'str'=>'WIDGET视图变量',
        ));
    }
}

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
