I've got a question/issue that I want to bounce off the list.
I have a list that extends over multiple pages. there might be 200
items,
and i don't want to have the items listed on the same page as it
would be
too long. i can break the list up, so i can have it be displayed
over
multiple pages. however, i want the user to select different items
from the
list. given that the selected items might be over different pages,
what's
the best way of keeping a running track of the items that have been
selected??
I could have each page be a form, and do a post/get where i then
keep track
of the selected items from page to page, but that would appear to
get ugly.
i'm looking for pointers to other sites/code that might have
already
implemented this kind of scenario.
thoughts/pointers would be appreciated...
Accumulate them in the session. When done, and before final action
you
could let them view a summary of selected items and allow deletion
of
any entries they don't want.
Unless they're likely to select hundreds of items I'd either go
with a
persisted GET var or a cookie. No need to drag server-side storage
into this.
Well he did say he had multiple pages. Maybe he's only displaying 5
per
page though. Still, sessions are easier to manage than GET vars since
you don't need to append them to every form action URL to accumulate
them. Session is managed transparently by PHP in most cases an amounts
to the approximate overhead of an include.
Seriously? You'd rather use sessions than explode, modify and implode
an array of numbers on each request? You really see that as a valuable
developer time-saver?
The mind boggles, but as I've said before and probably will again it's
always a personal choice, I'm just suggesting alternatives.
