CodeIgniter: How to get Controller, Action, URL in

Question

I have these URLs:

• 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

Ex:

$params = helper_function( current_url() )

Where $params becomes something like

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

Answer 1

The methods are deprecated.

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

You can access the properties instead.

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

See codeigniter user guide

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

With properties CI_Router::$directory, CI_Router::$class and CI_Router::$method being 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;

Answer 2

controller class is not working any functions.

so I recommend to you use the following scripts

global $argv;

if(is_array($argv)){
    $action = $argv[1];
    $method = $argv[2];
}else{
    $request_uri = $_SERVER['REQUEST_URI'];
    $pattern = "/.*?\/index\.php\/(.*?)\/(.*?)$/";
    preg_match($pattern, $request_uri, $params);
    $action = $params[1];
    $method = $params[2];
}

Answer 3

Use This Code anywhere in class or libraries

    $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

Answer 4

Another way

$this->router->class
