Question Get, Post, or other method?

[Diane]

Hi everyone,

I need a method to store the preferences of users who visit the site like this:

I created a series of pages,

on each page the user has a background and the name of a category, for example "DIY",

and only two buttons: "I'm interested" or "Skip ahead".

What I need is;

When the user clicks on "I'm interested", send it on the next page,

and simultaneously store the preference data somewhere,

so that after the last page the summary of the chosen preferences appears.

I think it is quite simple but unfortunately I know almost nothing about php and I don't know how to set it up.

Thanks
