Access denied. after post save

[kamilkurczak]

this is my complete function to post adding:

PHP Code:

public function addPost($forum_id, $thread_id, $post_data = array())
    {    
        global $vbulletin;
        require_once(CWD . '/includes/init.php');
        require_once(CWD . '/includes/functions_misc.php');
        require_once(CWD . '/includes/functions_databuild.php');
        
        $foruminfo = fetch_foruminfo($forum_id);
        $threadinfo = fetch_threadinfo($thread_id);
        
        $postdm =& datamanager_init('Post', $vbulletin, ERRTYPE_ARRAY, 'threadpost');
        //$postdm = new vB_DataManager_Post($vbulletin, ERRTYPE_STANDARD); 
        
        // set options
        //$postdm->setr('showsignature', $post_data['signature']);
        $postdm->setr('allowsmilie', $post_data['enablesmilies']);
        //$postdm->setr('htmlstate', $post['htmlstate']);
    
        // set data
        $postdm->setr('userid', $post_data['userid']);
        $postdm->setr('threadid', $post_data['threadid']);
        $postdm->setr('parentid', $post_data['parentid']);
        //$postdm->set('username', $post_data['username']);
        $postdm->setr('title', $post_data['title']);
        $postdm->setr('pagetext', $post_data['pagetext']);
        $postdm->setr('iconid', $post_data['iconid']);
        $postdm->setr('visible', $post_data['visible']);
        $postdm->setr('dateline', time());    
        $postdm->set_info('forum', $foruminfo);
        $postdm->set_info('thread', $threadinfo);    
        $postdm->pre_save();
            
        if(!empty($postdm->errors))
        {
            return $postdm->errors;
        }
        else
        {
            
            $post_id = $postdm->save();
            
            build_thread_counters($threadinfo);
            build_forum_counters($foruminfo);
            
            return $thread_id;
        }  

    } 


and this function is called by:

PHP Code:

protected function processForm(sfWebRequest $request, sfForm $form)
  {
    $form_name = $form->getName();  
    $form->bind($request->getParameter($form_name), $request->getFiles($form->getName()));
    if ($form->isValid())
    {
      // start vbulletin add thread part
      if(sfConfig::get('app_vbulletin_use'))
      {     
            $user_id = $this->getUser()->getGuardUser()->getId();
          $values = $this->form->getValues();
          
          if($form_name == 'post')
          {
              $vb = new vbConnector();
              $post_data = array( 'threadid'         => $this->thread_id, 
                                    'title'              => $values['title'], 
                                    'pagetext'         => $values['message'],
                                    'userid'        => $user_id,
                                    'open'            => 1,
                                    'visible'        => 1,
                                    'allowsmilie'     => 1,
                                    'parentid'        => 0,
                                    'iconid'        => 1,
                                    'signature'        => 0
                                );
              $this->errors = $vb->addPost($this->forum_id, $this->thread_id, $post_data);
          }
          else
          {
              $vb = new vbConnector();
              $thread_data = array( 'forumid'         => $this->forum_id, 
                                    'title'              => $values['title'], 
                                    'pagetext'         => $values['message'],
                                    'userid'        => $user_id,
                                    'open'            => 1,
                                    'visible'        => 1,
                                    'allowsmilie'     => 1
                                );
              $this->errors = $vb->addThread($this->forum_id, $thread_data);
          }
          
          if(!is_array($this->errors))
          {
              
              $this->redirect('@forum_thread?forum_id='.$this->forum_id.'&slug='.$this->errors);
          }          
      }
      // end vbulletin add thread part
          
    }
  }
