Sure it does, but the problem with submitting and storing data with that
is, that you have to remember every input that was done in each html
page e.g.:
page1(var1,var2) ->page2([var1,var2],var3)->page3([var1,var2,var3],var4)
This is not very convienient, page1, would submit var1 and var2, the php
script that gets these vars would then add them as hidden fields to
page2, this way they would be send along to page3, you see lots of work.
Therefore if have lots of data to store you do that for example in a
SESSION , you start a new session, then as log as this session is valid
you can store data on the server for this specific user, each page then
can access this SESSION data without the need of transfering if from one
page to the ther vuia form submits.
