Answer 1

You want to define a route that has the id as a parameter, so something like:

Route::get('/add-tour/{id}', [TourController::class, 'addTour']);  // Laravel 8
Route::get('/add-tour/{id}', 'TourController@addTour'); // Laravel 7

The {id} parameter in the URL will be passed in as the $id in your addTour function.

What you then do with the $id such as checking it is valid is up to you.
