Question

我只是将我的网站从localhost上传到带有filezilla的hostinger。我已经配置了数据库设置并且运行良好，但如果我想登录网站，我会得到不同的结果。它会给出错误＆＃34;用户名或密码错误＆＃34;。之后，我在localhost中运行该网站。使用相同的用户名/密码登录并运行。我不知道错误，我在本地和hostinger之间使用相同的代码

控制器/ login.php中

  <?php
  class Login extends CI_Controller {
   function __construct() {
    parent::__construct();
    session_start();
    $this->load->model(array('mlogin'));
   if ($this->session->userdata('email')) {
    $this->load->view('header1');
   }
   elseif (!$this->session->userdata('email')) {
    $this->load->view('header'); 
     }
     }
    function index() {
    $this->load->view('login');
    }

    $this->form_validation->set_rules('email', 'email', 'required|trim|xss_clean');
    $this->form_validation->set_rules('password', 'password', 'required|trim|xss_clean');

localhost php version 5.6.11

hostinger php version 5.6.18

Answer 1

Hostinger对大写敏感

更改此代码

$this->form_validation->set_rules('email', 'email', 'required|trim|xss_clean');
$this->form_validation->set_rules('password', 'password', 'required|trim|xss_clean');

用这个

$this->form_validation->set_rules('email', 'Email', 'required|trim|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'required|trim|xss_clean');

我觉得这段代码会给你0美元

$p = md5(mysql_real_escape_string($psw));

只需使用此

$p = md5($psw);

Codeigniter项目在hostinger和localhost之间有不同的结果
