Question

我在我的控制器目录中设置了一个管理文件夹，在其下面我有3个单独的子文件夹，里面有控制器。

-- Controllers
---- Admin
------ Dashboard
-------- dashboard.php
-------- file.php
------ Members
-------- members.php
-------- file.php
------ Settings
-------- settings.php
-------- file.php

我尝试在routes.php文件中路由它，就像这样

$route['admin/(:any)/(:any)'] = 'admin/$1/$2';
$route['admin/(:any)'] = 'admin/$1/$1';
$route['admin'] = 'admin/index';

我该怎么做才能解决这个问题？

Answer 1

此代码已在互联网上，但我对其进行了修改，使其适用于codeigniter 2.1

请在此处查看旧来源： http://glennpratama.wordpress.com/2009/10/20/multi-level-subfolder-for-controller-in-codeigniter/

在application / core目录中创建一个新文件MY_Router.php，复制下面的代码：

<?php

/*
 * Custom router function v 0.2
 *
 * Add functionality : read into more than one sub-folder
 *
 */

Class MY_Router extends CI_Router
{
    Function MY_Router()
    {
        parent::__construct();
    }

    function _validate_request($segments)
    {
        if (file_exists(APPPATH.'controllers/'.$segments[0].EXT))
        {
            return $segments;
        }

        if (is_dir(APPPATH.'controllers/'.$segments[0]))
        {
            $this->set_directory($segments[0]);
            $segments = array_slice($segments, 1);

            /* ----------- ADDED CODE ------------ */

            while(count($segments) > 0 && is_dir(APPPATH.'controllers/'.$this->directory.$segments[0]))
            {
                // Set the directory and remove it from the segment array
            //$this->set_directory($this->directory . $segments[0]);
            if (substr($this->directory, -1, 1) == '/')
                $this->directory = $this->directory . $segments[0];
            else
                $this->directory = $this->directory . '/' . $segments[0];

            $segments = array_slice($segments, 1);
            }

            if (substr($this->directory, -1, 1) != '/')
                $this->directory = $this->directory . '/';

            /* ----------- END ------------ */

            if (count($segments) > 0)
            {

                if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().'/'.$segments[0].EXT))
                {
                    show_404($this->fetch_directory().$segments[0]);
                }
            }
            else
            {
                $this->set_class($this->default_controller);
                $this->set_method('index');

                if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().'/' .$this->default_controller.EXT))
                {
                    $this->directory = '';
                    return array();
                }

            }

            return $segments;
        }

        show_404($segments[0]);
    }
}

Answer 2

“开箱即用”codeigniter不支持您的控制器目录中的多个子目录级别，只有一个。

There is a way to extend the routing class to support this, check this blog entry.

Answer 3

对于Codeigniter 3.x兼容性：由于删除了对PHP 4的支持，因此不再使用EXT常量。不再需要维护不同的文件扩展名，并且在这个新的CodeIgniter版本（3.x）中，EXT常数已被删除。请改用'.php'。

所以新的MY_Router.php：

<?php

/*
 * Custom router function v 0.3
 *
 * Add functionality : read into more than one sub-folder
 * Compatible with Codeigniter 3.x
 *
 */

Class MY_Router extends CI_Router
{
    Function MY_Router()
    {
        parent::__construct();
    }

    function _validate_request($segments)
    {

       if (file_exists(APPPATH.'controllers/'.$segments[0].".php"))
        {
            return $segments;
        }

        if (is_dir(APPPATH.'controllers/'.$segments[0]))
        {
            $this->set_directory($segments[0]);
            $segments = array_slice($segments, 1);

            /* ----------- ADDED CODE ------------ */

            while(count($segments) > 0 && is_dir(APPPATH.'controllers/'.$this->directory.$segments[0]))
            {
                // Set the directory and remove it from the segment array
            //$this->set_directory($this->directory . $segments[0]);
            if (substr($this->directory, -1, 1) == '/')
                $this->directory = $this->directory . $segments[0];
            else
                $this->directory = $this->directory . '/' . $segments[0];

            $segments = array_slice($segments, 1);
            }

            if (substr($this->directory, -1, 1) != '/')
                $this->directory = $this->directory . '/';

            /* ----------- END ------------ */

            if (count($segments) > 0)
            {

                if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().'/'.$segments[0].".php"))
                {
                    show_404($this->fetch_directory().$segments[0]);
                }
            }
            else
            {
                $this->set_class($this->default_controller);
                $this->set_method('index');

                if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().'/' .$this->default_controller.".php"))
                {
                    $this->directory = '';
                    return array();
                }

            }

            return $segments;
        }

        show_404($segments[0]);
    }
}

Answer 4

我遇到4-5 levels sub-directories的问题（比如/ controllers / folder1 / folder2 / folder3 / folder4 / my-controller）并从

更改while循环

while(count($segments) > 0 && 
     // checks only $this->directory having a /
     is_dir(APPPATH.'controllers/'.$this->directory.$segments[0]))

到

while(count($segments) > 0 && 
   // check $this->directory having a /
  (is_dir(APPPATH.'controllers/'.$this->directory.$segments[0]) ||  
      // check $this->directory not having /
      is_dir(APPPATH.'controllers/'.$this->directory.'/'.$segments[0])))

它对我有用。

上述内容适用于2-3 sub-directories，但不适用于4-5 sub-directory层次结构。

路由到CodeIgniter中的多个子文件夹
