Yii实现单用户博客系统文章详情页插入评论表单的方法

本文实例讲述了Yii实现单用户博客系统文章详情页插入评论表单的方法。分享给大家供大家参考，具体如下：

action部分：

    <?php
    function test($objs)
    {
     $objs->var=10;
    }
    class one
    {
     public $var=1;
    }
    $obj=new one();
    echo $obj->var.'<p>';
    test($obj);
    echo $obj->var;
    exit;

PostController.php页面：

    ...
    /**
    * Displays a particular model.
    * @param integer $id the ID of the model to be displayed
    */
    public function actionView($id)
    {
      $post=$this->loadModel($id);
      $comment=$this->newComment($post);
      $this->render('view',array(
        'model'=>$post,
        'comment'=>$comment,
      ));
    }
    protected function newComment($post)
    {
      $comment=new Comment();
      if(isset($_POST['Comment']))
      {
       $comment->attributes=$_POST['Comment'];
       if($post->addComment($comment))//==============================
       {
        if($comment->status==Comment::STATUS_PENDING)
         Yii::app()->user->setFlash('commentSubmitted','Thank you...');
        $this->refresh();
       }
      }
      return $comment;
    }
    ...

models/Post.php页面：

    ...
    public function addComment($comment)
    {
      if(Yii::app()->params['commentNeedApproval'])
       $comment->status=Comment::STATUS_PENDING;
      else
       $comment->status=Comment::STATUS_APPROVED;
      $comment->post_id=$this->id;
      return $comment->save();
    }
    ...

post/view.php页面：

    ...
    <div id="comments">
    <h3>Leave a Comment</h3>
    <?php if(Yii::app()->user->hasFlash('commentSubmitted')): ?>
     <div class="flash-success">
     <?php echo Yii::app()->user->getFlash('commentSubmitted'); ?>
     </div>
    <?php else: ?>
     <?php $this->renderPartial('/comment/_form',array(
     'model'=>$comment,
     )); ?>
    <?php endif; ?>
    </div><!-- comments -->
    ...

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
