我正在使用CodeIgniter＆amp; GoCart突然发现登录和注册函数在我的localhost环境中完美运行不能在实时服务器上运行。
没有抛出任何错误。当我尝试登录或注册时发生的一切都是页面刷新。没有会话或任何东西。我还检查了数据库，新用户也没有注册。这不是数据库连接问题 - 如果我更改了我的任何config/database.php我收到连接错误（我也成功地从数据库中提取其他数据）。
我没有编辑与表格直接相关的任何内容，而且我无法想到我编辑的任何会导致这种情况的内容。
任何人对于什么会导致登录或注册（表单提交）在localhost中工作但不在线时有任何想法？我的当地环境是WAMP。实时服务器是Unix机器。
编辑： 我发现在线服务器上没有任何表格，而不是专门登录/注册。例如，搜索表单也不起作用。
如果我在localhost上搜索某个字词，我会转到以下网址：http://localhost:8080/example.com/search/45d20b1d2cc2d52e74b3cbf1750a2e31/name/ASC/0
如果我在线搜索一个术语，我会被带到URL：
http://example.com/search/并显示错误＆＃39;请输入搜索字词。＆＃39;这让我觉得问题不在于具体登录，而是提交表单的方式有问题。

答案 0 :(得分：2)
答案：此问题不是编码之一。在耗尽了我能想到的所有选项后，我发现Dreamhost可以选择在所有URL之前忽略/强制/禁用前面的 www。。由于代码不是用www编写的，我选择“删除www。并将其重定向到http：//”，表格立即重新开始行动。
作为旁注，我在这个项目中经历了Dreamhost共享托管这么多愚蠢的小问题，我永远不会考虑使用他们的服务。这么多小怪癖（以及适度无助的支持人员）加起来推迟我的项目大约一个星期......
