php - Yii, Fatal error: Call to a member function addComment() on a non-object -

this question has answer here:

• call member function on non-object [duplicate] 8 answers

i new yii , while trying make blog application of own made function add comment post.

however, have done according theory still getting :

fatal error: call member function addcomment() on non-object in /htdocs/blog/protected/controllers/postcontroller.php on line 63 

my post.php model class has function :

public function addcomment($comment){         $comment->tbl_post_id = $this->id;         return $comment->save();     } 

and postcontroller.php has these 2 function, 1 creating comment , other 1 altering view file.

public function actionview($id)    {        $post=$this->loadmodel($id);        $comment=$this->createcomment($post);        $this->render('view',array(          'model'=>$post,             'comment'=>$comment, )); }      protected function createcomment($post)    {      $comment=new comment;      if(isset($_post['comment']))      {        $comment->attributes=$_post['comment'];        if($post->addcomment($comment)) // **this line 63**        {          yii::app()->user->setflash('commentsubmitted',"your comment has been added." );          $this->refresh();        } }      return $comment;    } 

so logically calling member function addcomment inside post model class using $post->addcomment, , member functions of model initialized right? , logicaly shouldn't correct right? however, getting above fatal error.

what doing wrong?

any appreciated.

regards,

p.s - sorry if doing stupid.

$post isn't object since don't declare anywhere

 protected function createcomment($issue)  {    $comment=new comment;    if(isset($_post['comment']))    {      $comment->attributes=$_post['comment'];      if($post->addcomment($comment)) // **this line 63**      {        yii::app()->user->setflash('commentsubmitted',"your comment has been added." );        $this->refresh();      }    }    return $comment;  } 

on line 63 he's searching variable named $post not exist. have create or load db you're doing actionview()

$post=$this->loadmodel($id); 

obviously load it, need $id has passed createcomment() function
