old function

Hello,

I cannot understand what this code means:

old('positionId')

I also cannot understand the definition:

function old($key = null, $default = null)
    {
        return app('request')->old($key, $default);
    }

Thanks in advance.

Which drive you here : https://laravel.com/docs/5.7/requests#old-input

So it will retrieve the positionId which was in the session

this function helps you retrieve old input from previous request, mostly use to show previous submitted data on form with validation error, so that end user don't need to re-enter the details.
