CodeIgniter: How to get Controller, Action, URL information

Question

I have these URLs:

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

How to get controller nam

Answer 1

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

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

Answer 2

Another way

$this->router->class

Answer 3

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

Answer 4

$this->router->fetch_class(); 

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

// method

Answer 5

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 6

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;
