  Subject: [nycphp-talk] shopping cart help


  I need a back-to-basics shopping cart tutorial in PHP/mySQL.  I thought I had it down and I failed, as usual. Here is what I mapped out as a spec:

  3) initial work on bestilling.php to contain the following plan:

   1) Cookie: 'nordicnet_bestilling' to contain unique, random 16-char string
   2) Table: nnet_produkt_bestilling to contain ordering information bundled by
             unique bestilling_id (16-char string)
    a) produkt_id
    b) farge_id
    c) storrelse_id
    d) quantity ordered
    e) bestilling_id
    f) nordicnet_registration_number
   3) *PROPOSAL* To make cookie a timed cookie - if user does not check out in X hours
      the cookie will be deleted
   4) *PROPOSAL* CRON-based PHP script to systemically wipe out any stray rows in
      nnet_produkt_bestilling that have not yet been checked out
   5) Idea plan for bestilling:
    a) User will order produkt in vis_varegruppen.php
    b) bestilling.php will do server-side checking of produkt, farge, storrelse
       and quantity based upon entry in nnet_produkt_farge_storrelse_assoc
    c) bestilling.php will then check if $_COOKIE['nordicnet_bestilling'] 
       already exists (meaning you have an order # - or, a cart ('bestill')
    d) If you have a cart then check if there is already a row in
       nnet_produkt_bestilling with same produkt_id/farge_id/storrelse_id with your
       matching bestilling_id
    e) If so then increase quantity ordered by the quantity you ordered and check
       quantity totals against nnet_produkt_farge_storrelse_assoc
    f) If NOT then add new row with produkt_id, farge_id, storrelse_id and
       quantity with your bestilling_id and registration number
    g) -- If you do NOT have a cart (no cookie) then generate a new cart (bestilling)
       id into a cookie
    h) If other people ordered the same item be sure to check their quantities
       ordered against yours and what is in stock before proceeding

  So far this is what happens:

  1) I enter products into the cart
  2) If I delete items from the cart, they can be deleted; if I delete all items from my cart, the cart cookie is deleted, I think.
  3) I try to re-enter the same item into the cart, it inserts into the db w/ a NULL value for 'nnet_user_bestilling_id' which is
      the cart id (which it's not supposed to do) and browser-side logic fails, you get the wrong screen and all kinds of garbage I cannot even go into because it's in Norwegian

  I have tried for nearly 24 hours to build a cart and I can't seem to get it done.  I really need some help.

  Phil
