How to find route of a current page?
opencart, php
Solution
Right answer is `$this->request->get['route'];`.
In order to catch the current route, you can use `$this->request->get['route'];` in the `index()` function of the `catalog/controller/common/header.php` file. The `header.php` file is a part of practically any frontend output (as I understand, right now you are not sure what controller is used in the `http://example.com/desktops` URL, so you need right place where you can run your code in any case).
The SEO module does not unset this part of the request object. Also, keep in mind, in the middle of OpenCart code generation the `$_GET` array and the `$this->request->get` array are not the same things. You won't catch current route (in "path/controller/action" format) in the `$_GET` superglobal PHP's array when SEO module is in action, but you can catch it in any controller by using a `$this->request->get` array which is prepared for you by OpenCart engine.
Problem
Is there a line of code that I can use in the controller that determines the route of a current page? For example, I would like to find the route of the page with SEO url `https://example.com/desktops` (this should return the route `product/category`). Similarly, url such as `https://example.com/index.php?route=product/product&path=18&product_id=47` should return route as `product/product`.
