Laravel - Getting Started - Writing Global Scopes

Writing a global scope is simple. First, define a class that implements the Illuminate\Database\Eloquent\Scope interface. Laravel does not have a conventional location that you should place scope classes, so you are free to place this class in any directory that you wish.

The Scope interface requires you to implement one method: apply. The apply method may add where constraints or other types of clauses to the query as needed:

    
    where('created_at', '<', now()->subYears(2000));
        }
    }
	
If your global scope is adding columns to the select clause of the query, you should use the addSelect method instead of select. This will prevent the unintentional replacement of the query's existing select clause.
