I have URL like this: `http://localhost/sitename/some-post-title/code=24639204963309423`

Now I have one `findUser` function in my controller file

```
public function findUser() {
   // I have tried with $_GET['code']
}

```

and I am trying to get `code` variable value inside this function. I have tried with `$_GET['code']` but did not worked.

Any Idea how to get value inside controller function?

Thanks.
