从控制器Laravel 5.2在$ request-> input（）中注入值

Question

Is there a way to do something like this in the controller?

$request->input(['new_field_name' => 'new_val']);

I've googled a lot, but the only thing I've found was related to Laravel's 4.x formatInput method, which has been removed from the 5.x

I need to inject a specific field in the $request when the request has passed the validation, then save the new record in the db.

Any clue? Thanks to everyone!

Method merge is the right tool for this.

Example of a typical use case (saving a slug given a title):

$request->merge(['slug' => Str::slug($request->title)]);
