Yii 之视图数据块

控制器代码:

   public $layout = 'common';
    public function actionStudent(){
        $data = array('page_name'=>'Student');
        return $this->render('student',$data);
    }

    public function actionTeacher(){
        $data = array('page_name'=>'Teacher');
        return $this->render('teacher',$data);
    }

公共布局文件common代码:

<!DOCTYPE html>
<html>
<head>
    <title>
        <?php if(isset($this->blocks['webTitle'])):?>
            <?=$this->blocks['webTitle'];?>
        <?php else:?>
            commom
        <?php endif;?>
    </title>
    <meta charset="UTF-8">
</head>
<body>
<h1>这是Common内容</h1>
<div>
    <?=$content?>
</div>
</body>
</html>

视图student代码:

<?php $this->beginBlock('webTitle');?>
<?=$page_name?>页面
<?php $this->endBlock();?>

<h1> Hello <?=$page_name?></h1>

视图teacher代码:

<h1> Hello <?=$page_name?></h1>

<?php $this->beginBlock('webTitle');?>
<?=$page_name?>页面
<?php $this->endBlock();?>

总结:如果需要在视图中改变公共模板中的内容,需要使用block方法,例如上面例子中改变了common页面的title。
