| 用ci 3.x 在练习写一个blog遇到一些问题http://localhost/blog/post/6 这是其中一篇文章 文章下方有个回应文章的功能,提交的路由为
 http://localhost/blog/comments/add_comment/6
 
 问题:
 如果form_validation= FALSE , redirect 后, 為什麼无法显示 form_error 信息,
 请问是哪里出问题了呢?
 
 
 class Comments extends CI_Controller {
 
 public function __construct()
 {
 parent::__construct();
 
 }
 public function add_comment($post_id){
 $name = $this->input->post('name',true);
 $email = $this->input->post('email',true);
 $comment = $this->input->post('comment',true);
 
 $this->form_validation->set_rules("name", "name", "trim|required");
 $this->form_validation->set_rules("email", "email", "trim|required");
 $this->form_validation->set_rules("comment", "comment", "trim|required");
 
 if ($this->form_validation->run() == FALSE)
 {
 redirect('post/$post_id);
 }
 else
 {
 
 
 }
 
 
 }
