How to make a dynamic prefix for a router?

Question

Laravel

There is a project in which it is necessary to display the name of the city as a prefix for some pages , that
is
: , all addresses must go to their controllers, regardless of the prefix. What is the best way to implement this? How to use a dynamic prefix (including the option without a prefix should work)? I tried many different options, everything works somehow crookedly.

Answer 1

Let's say the visitor has chosen a region, and we have put the code of this region in his session.
Then you can do this:

Route::prefix(session('region_code'))->group(function() {
    Route::get('catalog', '...');
    // ...
});
