CodeIgniter: How to get Controller, Action, URL information

提问by noname.cs

I have these URLs:

我有这些网址：

• http://backend.domain.com/system/setting/edit/12
• http://backend.domain.com/product/edit/1

• http://backend.domain.com/system/setting/edit/12
• http://backend.domain.com/product/edit/1

How to get controller name, action name from these URLs. I'm CodeIgniter newbie. Are there any helper function to get this info

如何从这些 URL 中获取控制器名称、操作名称。我是 CodeIgniter 新手。是否有任何帮助函数来获取此信息

Ex:

前任：

$params = helper_function( current_url() )

Where $paramsbecomes something like

哪里$params变得像

array (
  'controller' => 'system/settings', 
  'action' => 'edit', 
  '...'=>'...'
)

You could use the URI Class:

您可以使用URI 类：

$this->uri->segment(n); // n=1 for controller, n=2 for method, etc

I've also been told that the following work, but am currently unable to test:

我还被告知以下工作，但我目前无法测试：

$this->router->fetch_class();
$this->router->fetch_method();

Instead of using URI segments you should do this:

您应该这样做，而不是使用 URI 段：

$this->router->fetch_class(); // class = controller
$this->router->fetch_method();

That way you know you are always using the correct values even if you are behind a routed URL, in a sub-domain, etc.

这样你就知道你总是使用正确的值，即使你在路由 URL 后面，在子域中，等等。

The methods are deprecated.

这些方法已被弃用。

$this->router->fetch_class();
$this->router->fetch_method();

You can access the properties instead.

您可以改为访问属性。

$this->router->class;
$this->router->method;

See codeigniter user guide

请参阅codeigniter 用户指南

URI Routing methods fetch_directory(), fetch_class(), fetch_method()

With properties CI_Router::$directory, CI_Router::$classand CI_Router::$methodbeing public and their respective fetch_*()no longer doing anything else to just return the properties - it doesn't make sense to keep them.

Those are all internal, undocumented methods, but we've opted to deprecate them for now in order to maintain backwards-compatibility just in case. If some of you have utilized them, then you can now just access the properties instead:

$this->router->directory;
$this->router->class;
$this->router->method;

URI 路由方法 fetch_directory()、fetch_class()、fetch_method()

使用 properties CI_Router::$directory，CI_Router::$class并且 CI_Router::$method是 public 并且它们各自fetch_*()不再做任何其他事情来返回属性 - 保留它们没有意义。

这些都是内部的、未记录的方法，但我们现在选择弃用它们，以保持向后兼容性以防万一。如果你们中的一些人已经使用了它们，那么您现在可以改为访问属性：

$this->router->directory;
$this->router->class;
$this->router->method;

Another way

其它的办法

$this->router->class

As an addition

作为补充

$this -> router -> fetch_module(); //Module Name if you are using HMVC Component

Update

更新

The answer was added was in 2015 and the following methods are deprecated now

答案是在 2015 年添加的，现在不推荐使用以下方法

$this->router->fetch_class();  in favour of  $this->router->class; 
$this->router->fetch_method(); in favour of  $this->router->method;

Hi you should use the following approach

嗨，您应该使用以下方法

$this->router->fetch_class(); // class = controller
$this->router->fetch_method(); // action

for this purpose but for using this you need to extend your hook from the CI_Controllerand it works like a charm, you should not use uri segments

为此目的，但要使用它，您需要从 扩展您的钩子CI_Controller，它就像一个魅力，您不应该使用 uri 段

回答by Aslam Patel

Use This Code anywhere in class or libraries

在类或库中的任何地方使用此代码

    $current_url =& get_instance(); //  get a reference to CodeIgniter
    $current_url->router->fetch_class(); // for Class name or controller
    $current_url->router->fetch_method(); // for method name

If you using $this->uri->segment , if urls rewriting rules change, segments name matching will be lost.

如果你使用 $this->uri->segment ，如果 url 重写规则改变，段名称匹配将丢失。

回答by PrakashG

Last segment of URL will always be the action. Please get like this:

URL 的最后一段将始终是操作。请像这样：

$this->uri->segment('last_segment');

回答by Fel

$this->router->fetch_class(); 

// fecth class the class in controller $this->router->fetch_method();

// 将控制器中的类命名为 $this->router->fetch_method();

// method

// 方法
