I have a input of start date, and input of days also, then want store expiry date without $request->input? and with using start date + days in single submit.

Well you need to do the calculation somewhere right? So you either get the numbers from the request or your have to combine the two in the frontend already. You can for example use momentjs for that.

I'm not sure if I understand your question 100%, can you maybe explain a little bit more about it?

Thanks for your understanding. is it possible with Moment.js or any Other?

I don't get what you mean 'without $request->input'

You need to get the input from your user if you want to save it in the database?

Thanks Snapey for your attention,

1. I have Two inputs with date & days
2. I have also third input with expiry date. Which i want to calculate date+days with front end or want to store with with backend calculation

Which is better for freshers?

later, do you need to know date and days, or just expiry?

For instance, in two months time, when it reaches expiry, will you need to know that days was 60?

hey snapey,

I want store start date , days and also expiry date i.e.

For Example : Ordered date/Created by customer + transit days for delivery = expected delivery date.

ok so in the controller.

$ordered = Carbon::parse($request->date);

$expected = $ordered->copy()->addDays($request->days);

obviously I don't know any of your field names or what you want to do with the data
