在codeigniter中重定向的空白页

Question

我试图在成功登录后重定向到另一个控制器home.php，但不知何故，url指向正确的控制器，但我得到一个空白页，即使我尝试回应“某事”;死;在home.php的index（）中，它不显示回显的消息。

我的控制器代码是：

的login.php

    function index(){
        //if Admin already logged in, send to Admin home

        $this->data['message']='';
        $this->data['msg_class'] = '';
        $post_array=$this->input->post();

        $data['old_images']=$this->mod_common->getBgImages();

        if($this->input->cookie('remember') == 'on')
        {
            //echo $this->input->cookie('username');
            $this->data['message']=strip_tags($this->mod_login->check_cookie_login());
            if($this->data['message']=='Login Successful'){
                $this->data['msg_class'] = 'sukses';

                 redirect('home');              
            }else{
                $this->data['msg_class'] = 'gagal';
            }
        } 
        if($this->input->post('action')=='adminLogin'){

        //print_r($this->input->post()); die;

            if(isset($post_array['remember'])){
                $username_cookie= array(
                    'name'   => 'uusername',
                    'value'  => $post_array['username'],
                    'expire' => '865000',
                    'secure' => FALSE
                );

                $password_cookie= array(
                    'name'   => 'userpass',
                    'value'  => $post_array['userpass'],

                $remember_cookie= array(
                    'name'   => 'remember',
                    'value'  => 'on',
                    'expire' => '865000',
                    'secure' => FALSE
                );

                $this->input->set_cookie($username_cookie); 
                $this->input->set_cookie($password_cookie); 
                $this->input->set_cookie($remember_cookie);
