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：
<?phpfunction 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。
