Hi,
I was just about to write YASB (Yet Another Shopping Basket)
and I thought, hang on, there's this CPAN thing and maybe
I could get one from there.
But to my dismay I couldn't find anything!
- So before I start writing a module I thought
I'd see what everyone want's out of a shopping basket.
I think it will be heavily based on using Apache::Session,
any other ideas / comments are very welcome.
Thanks
Leo

Shopping::Basket Proposal Version 0.000000001
----------------------------------------------------------
Aim:
To create a module which can be used to easily implement
shopping baskets with lots of flexibility.
Requirements of this module:
- Generate UID
- Store item X in Basket Y for user UID
- Store user details
(what happens if this is across multiple sites ?)
- Password option
- Option to validate basket item on retrieval (don't think
this needs to be in the module)
Functions which need to be able to be overridden (eventually)
- Function to generate UID (might need to integrate to current system)
- How to store the basket
- DBI
- File
- anything else ?
- Password encryption
- standard 'salt' and 'pepper'
- other
- Validate of item (see requirements above)
How is the UID passwd around
- Cookie
- Session
- What happens if the user needs to login, login name might not be unique.
Storage format:
my %uid = ();
%uid{user}{login} = 'Leo'
%uid{user}{password} = 'wibble'
%uid{user}{email} = '[EMAIL PROTECTED]'
%uid{toys}{item_id}{id} = '2346'
%uid{toys}{item_id}{name} = 'Furby'
%uid{toys}{item_id}{price} = '4.99'
%uid{toys}{item_id}{price_code} = 'GBP'
etc..
OK, so how would we use it ????
## set up basket
my $basket = Emap::Shopping::Basket->new({
'uid_generator' => '', ## Will use default or call this to generate
if not
'dbh' => $dbh, ## Must be parsed in with r/w permissions,
## if not parsed in will default to file
storage ?
'password_generator' => ''; ## Will use default
});
## Create a new basket
$basket = Emap::Shopping::Basket->setup_new_user();
## Get the UID
my $uid = $basket->get_uid
## Get a previous basket
$basket = Emap::Shopping::Basket->setup_existing_user($uid);
## Add an item in
my %details = ('id' => '123345',
'name' => 'Furby',
'price' => '4.99',
'price_code' => 'GBP'
);
$basket->add_item('$basket_number','item_id',\%details);
## Add user details
## This will override any current details of the same key
## but will leave all others alone.
my %user_details = (
'name' => 'leo',
'password' => 'wibble',
'email' => '[EMAIL PROTECTED]'
);
$basket->add_user_details(\%user_details);
## Get a list of the baskets
my @basket_list = $basket->list_baskets();
e.g. $basket_list[3] = 'fruit';
## Get a basket
my %basket_contents = $basket->get_basket($basket_list[3]);
## Delete an item
$basket->delete_item($basket_number, $item_id);
## Reports
## Some script to go through ALL users and their baskets
## and generate automatic reports.
