I am doing a module that has different steps before the checkout and in one of the screens i need to save a value to add in the order.
I don't have any trouble to get the value and sending via ajax to the controller but i am not sure the best way to keep this value and get it after the client refresh the page select the product and goes to the checkout.
Not sure if it is better to use e session, cookie or save in a custom table with some kind of session id ?
General answer will be:
IF you want more secure and long term persistence of data which should
accessible anytime also for logging and history purpose
IF data belongs to existent entity
Store it in relevant entity table probably by extending model and
adding column
ELSE data do not fit any existent entity
Create new model and store data in custom table
ELSE
Use local storage to keep data and retrieve them while required
Avoid using sessions and cookies. Local storage should be a better solution unless some additional arguments strengthen one of the former approach.
