如何使用 codeigniter 3 在子文件夹中路由控制器? [英] How to routing controllers in sub folders using codeigniter 3?

问题描述

我在控制器文件夹的子文件夹中创建了一个控制器，在子文件夹中我创建了一个登录控制器.

I have create an controller in subfolder of controller folder and in subfolder i create an login controller.

但是我无法访问这个控制器并且已经在路由文件中给出了规则.

But i couldn't access this controller and already given rule in route file.

结构:

Controller
--admin
   ---login.php

路由规则:

$route['default_controller'] = 'admin/login';
$route['admin_login'] = 'admin/login';

推荐答案

默认情况下，codeIgniter 3 及以上版本不能在默认控制器路由中使用子文件夹.

By default codeIgniter 3 versions and up you can not use sub folders in your default controller route.

为了能够使用 default_controller 中的子文件夹，您需要使用 MY_Router.php

To be able to use a sub folder in default_controller you need to use a MY_Router.php

$route['default_controller'] = 'admin/login';

MY_Router.php

<?php

class MY_Router extends CI_Router {
    protected function _set_default_controller() {

        if (empty($this->default_controller)) {

            show_error('Unable to determine what should be displayed. A default route has not been specified in the routing file.');
        }
        // Is the method being specified?
        if (sscanf($this->default_controller, '%[^/]/%s', $class, $method) !== 2) {
            $method = 'index';
        }

        // This is what I added, checks if the class is a directory
        if( is_dir(APPPATH.'controllers/'.$class) ) {

            // Set the class as the directory

            $this->set_directory($class);

            // $method is the class

            $class = $method;

            // Re check for slash if method has been set

            if (sscanf($method, '%[^/]/%s', $class, $method) !== 2) {
                $method = 'index';
            }
        }

        if ( ! file_exists(APPPATH.'controllers/'.$this->directory.ucfirst($class).'.php')) {

            // This will trigger 404 later

            return;
        }
        $this->set_class($class);
        $this->set_method($method);
        // Assign routed segments, index starting from 1
        $this->uri->rsegments = array(
            1 => $class,
            2 => $method
        );
        log_message('debug', 'No URI present. Default controller set.');
    }
}

还要确保您遵循 命名 文件

Also make sure your you follow the codeIgniter way of naming files

文件名:Login.php

File name: Login.php

<?php 

class Login extends CI_Controller {
    public function index() {

    }
}
