CodeIgniter 4 提交表单导致返回同一页面

Question

我正在尝试提交我的 login/registration 表单。我怀疑是因为我没有设置 post 路由，但即使添加了这些路由，它仍然会指向同一页面。我可以直接访问这些页面，例如 localhost:8080/SignUpController/store 但似乎无法获取要提交到这些页面的表单。这是代码：

路线

$routes->get('/', 'SignupController::index');
$routes->post('/', 'SignupController::store');

$routes->get('/signup', 'SignUpController::index');
$routes->post('/signup', 'SignUpController::store');

$routes->get('/signin', 'SignInController::index');
$routes->post('/signin', 'SignInController::loginAuth');

在此之前，我遇到了一个问题，点击登录或注册后，它会将我带到一个页面，例如 http://localhost/Ci4/index.php/signin，这会给我一个 404找不到网页。将 baseURL 改回默认的 http://localhost:8080/（这是我更喜欢使用的）似乎并没有解决这个问题所以经过一些研究似乎移动 index.php 和从 public 文件夹到项目根目录的 .htaccess 文件解决了这个问题。现在我遇到了登录和注册按钮似乎没有任何作用的问题。我不确定这是否与问题相关，但我想我可以添加此信息。

如能提供任何帮助或为我指明正确的方向，我们将不胜感激。我还使用 XAMPP 作为我的网络服务器。

Answer 1

您已将路由设置为“/signup”和“/signin”。在您的表单操作中您需要使用这些 uris，因此更改如下

action="<?php echo base_url(); ?>/SignupController/store"

到

action="<?php echo base_url(); ?>/signup"

和

action="<?php echo base_url(); ?>/SigninController/loginAuth"

到

action="<?php echo base_url(); ?>/signin"

Answer 2

我最终重新启动了它，一切正常。我不记得我做了什么，但是，我相信 Tsefo 的回答是主要问题。

至于导致“http://localhost/Ci4/index.php/signin”页面的问题 URL 是因为我设置了 Auth 过滤器以拒绝访问某些页面，如果用户未登录。我不知道为什么我当时没有想到...

Auth.php

<?php 

namespace App\Filters;
use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use CodeIgniter\Filters\FilterInterface;

class Auth implements FilterInterface
{
    public function before(RequestInterface $request, $arguments = null)
    {
        // if user not logged in
        if(! session()->get('logged_in')) {
        // then redirct to login page
        return redirect()->to('/login'); 
        }
    }
    //--------------------------------------------------------------------
    public function after(RequestInterface $request, ResponseInterface $response, $arguments = null)
    {
    // Do something here
    }
}
