How to change the path in Laravel routers if the query parameters are not found?

Question

Laravel

Route::get('/storage/previews/{photo}.{width}.{ts}.jpg.crop.{from}.jpg', '[email protected]')
          ->where('photo', '[0-9]+')
->where('from', '[0-9]+')
 ->where('width', '[0-9]+')
 ->where('ts', '[0-9]+')
 ->name('photo-preview-crop');

The bottom line is that if the file is not found by where -> replace the file with a standard image. How can this be implemented?

Answer 1

Collect the path in the controller, check for the existence of the file and return the one you think is necessary
