当表值为null时，页面重定向到错误的url

Question

默认情况下，页面重定向到user/profilepicture/或表值$user->profile图片是否为null。

if($this->session->userdata("user_id"))//If already logged in
    {
        $userID = $this->session->userdata("user_id");
        $data['user'] = $this->m_user->getRows($userID);
        //load the view
      if($user->profile_pic == null)
      {
         redirect(base_url().'user/profilepicture/'); 
      }else{
         redirect(base_url().'blog/');
      }

    {
        $userID = $this->session->userdata("user_id");
       $data['user'] = $this->m_user->getRows($userID);
        //load the view
      if( $data['user']['profile_pic'] == null && $data['user']['profile_pic']!= null)
      {
         redirect(base_url().'user/profilepicture/');

if($this->session->userdata("user_id"))//If already logged in
    {
        $userID = $this->session->userdata("user_id");
        $data['user'] = $this->m_user->getRows($userID);
        //load the view
      if($user->profile_pic==null)
      {     
            $url = base_url().'user/profilepicture/';           
      }else{
            $url = base_url().'blog/';
