I have a need to do a 2-step form, like so:user selects some parameters & submits - they are presented with available product modelsanother form interface shows up that shows per-product-model options. User selects those options and submits - they are presented with pricing/detailsI am struggling about how to go about doing this.  One consideration I want to save all the form data in the database so that user can later recover their selection.Is there a recommended way to do this?I know how to do a single-step form, to where everything is submitted at one time, but when it comes to doing a two-step form, I am asking myself things likedo I use SESSION?do I reload first part of the form into the secondary form?do I just have separate forms? but how do I join their data into one?
