What does the signature of your `editpass` function look like? Unless you’ve done something weird with routing, you should be able to just use `function editpass($id)` and the 15 will be in the `$id` variable.

Here is my editpass function, it allows a user to change its password and username with a form.  
I made i like the default edit function of the UsersController and as you can see i did let the $id = null

My apologies, I missed the part about `isAuthorized`. Take a look at `$this->request->params['pass']`.

I got it with  
$this-\>request-\>params[‘pass’][0];  
(i added [0] because it’s an array).  
Thank you very much !

Here is my final _isAutorized_ function :

```
public function isAuthorized($user){
   if($this->request->getParam('action') ==='editpass' && $this->request->getParam('pass')[0] === (string)$this->Auth->user('id'))
       return true;
   else
       return parent::isAuthorized($user);
}
```

Otherwise you can use php function [parse\_url](http://php.net/manual/en/function.parse-url.php) and get last key of your array (it’s also good to check if it’s is\_numeric or not)

```
$last_key = key(array_slice($array, -1, 1, TRUE));
```
