如何修复CodeIgniter基本url和css链接,codeigniter,Codeigniter,我是CodeIgniter的新手，我正在尝试用session创建登录表单。我被困在一个点上，用户名和密码字段是空的，而不是没有显示CSS 我对此做了更多的研究，发现当我第一次打开我的project_登录表单时，css链接看起来像是localhost/ci_project/assets/bower_components/bootstrap/dist/css/mystyle.css 当用户名和密码为空时，点击登录按钮后css链接如下（Auth是我编写登录函数的控制器） localhost/ci_pr

我是CodeIgniter的新手，我正在尝试用session创建登录表单。我被困在一个点上，用户名和密码字段是空的，而不是没有显示CSS

我对此做了更多的研究，发现当我第一次打开我的project_登录表单时，css链接看起来像是localhost/ci_project/assets/bower_components/bootstrap/dist/css/mystyle.css

当用户名和密码为空时，点击登录按钮后css链接如下（Auth是我编写登录函数的控制器） localhost/ci_project/Auth/assets/bower_components/bootstrap/dist/css/mystyle.css

$config['base\u url']='http://localhost/ci_project/'
;

尝试相对路径，如下所示：

href=“/assets/bower\u components/etc..

我尝试了你的建议，如果你不解释为什么不能使用base\u url（）尝试自动加载url帮助程序并删除手动加载。然后看看它是否有效
