Codeigniter 3登录问题直接进入页面而没有验证

Question

I have an issue where every time I click on login it just takes me to my page it seems to not be checking to see if the username or password was entered. I am not sure what the issue is I changed the line if ($this->form_validation->run() == FALSE) to true and then I just get redirected back to the login when I enter correct password. I think it is something simple I am just missing. If anyone has an idea any direction would help in the mean time I will keep figuring it out.

Controllers

Verifylogin.php controller

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

   parent::__construct();

 }

 function index()
 {
   //This method will have the credentials validation
   $this->load->library('form_validation');

   if($this->form_validation->run() == false)
   {
     //Field validation failed.  User redirected to login page
    $this->load->view('person_view');
   }
   else
   {
     //Go to private area
     redirect('Person', 'refresh');
   }

 }

Answer 1

Use $this->form_validation->run() === FALSE instead, with 3 = signs.
