I want to use back button in my custom made form stepper. I have 3 steps and sending data from first step to second and from second to third (there is no option to skip from third to first etc.) and after third step I am saving data in DB (before not).
So I need solution how to use Back button on third step to get on second step with previous filled data. I have read similair topic (Back button re-submit form data ($_POST)) where answer is always -> use GET method.
In my case GET method isn't good solution because problem is that URL (Uniform Resource Locator) is limited on 2.083 characters and sometimes I send 100 chars in link but sometimes more than 3k.
