Codeigniter 项目在托管程序和本地主机之间有不同的结果答案

【问题标题】：Codeigniter project have different result beetween hostinger and localhostCodeigniter 项目在托管程序和本地主机之间有不同的结果
【发布时间】：2016-07-15 12:20:21
【问题描述】：

我只是使用 filezilla 将我的网站从 localhost 上传到托管程序。我已经配置了数据库设置并且一切正常，但是如果我想登录网站，我会得到不同的结果。它给出错误“用户名或密码错误”。之后，我在本地主机中运行该网站。使用相同的用户名/密码登录及其工作。我不知道错误，我在本地和托管程序之间使用相同的代码

控制器/login.php

    $this->load->view('header1');
   }
   elseif (!$this->session->userdata('email')) {
    $this->load->view('header'); 
     }

localhost php 版本 5.6.11

hostinger php 版本 5.6.18

【问题讨论】：

在这种情况下，您需要调试在现场上传的代码。只需打开一个您进行查询的文件，即可从数据库中获取提供的登录详细信息的记录。回声查询并在实时数据库中检查它。如果您有行，则表示查询和登录详细信息很好，否则更改登录详细信息并重试。
如果你自动加载会话库，你不需要使用这个session_start();
还是不行。帮帮我@wolfgang1983
代码和数据库连接正在检查数据库中的数据——你的用户名和密码。您提到您上传了文件，并配置了数据库连接，但是数据呢？如果你转移了，你是怎么做到的？

标签： php mysql codeigniter hosting

【解决方案1】：

Hostinger 对大小写敏感

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');

有了这个

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

我认为这段代码会给你 $p 的 0

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

就用这个

$p = md5($psw);
