Yikes, Who would have thought something so easy would be such a pain in the butt.
I solved it with embedded if-else clauses. Thx all -----Original Message----- From: mayo [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 17, 2005 9:19 AM To: 'php' Subject: [PHP] array, trouble updating I usually work with cold fusion and took on a little project to get my feet wet in php and am spinning my wheels. What I thought might be difficult was easy and what I thought would be a piece of cake has caused me much grief over the last few days. I'm making a little shopping basket, writing the results to a file, ftping the file to a distributor and sending the CC data to merchant services company. Write to file - easy FTP file to distributor - easy Updating the array in the shopping basket -- not so easy !!??!! A shopping basket should be able to add and delete items (done) You should be able to delete the whole basket (done) Now I need to be able to update quantity - I've spent at least 5 or 6 hours on this and have gotten nowhere!!! This learning exercise is getting to be a major time drag. Any hints would be good. The code is below: <?php if ($action == "empty") { while ($ses_basket_items > -1) { array_splice ($ses_basket_name, $ses_basket_items, 1); array_splice ($ses_basket_amount, $ses_basket_items, 1); array_splice ($ses_basket_price, $ses_basket_items, 1); array_splice ($ses_basket_id, $ses_basket_items, 1); $ses_basket_items--; } } if ($action2 == "deleteItem") { array_splice ($ses_basket_name, $position, 1); array_splice ($ses_basket_amount, $position, 1); array_splice ($ses_basket_price, $position, 1); array_splice ($ses_basket_id, $position, 1); $ses_basket_items--; } ?> <?php if ($_GET['basket']!=""){ if (session_is_registered('ses_basket_items')){ $basket_position_counter=0; $double=0; if ($_SESSION['ses_basket_items']>0){ foreach ($_SESSION['ses_basket_name'] as $basket_item){ if ($basket_item==$_GET['basket']){ $double=1; $subtract=1; $basket_position=$basket_position_counter; } $basket_position_counter++; } } if ($double==1){ $oldamount=$_SESSION['ses_basket_amount'][$basket_position]; $_SESSION['ses_basket_amount'][$basket_position]++; $amount=$_SESSION['ses_basket_amount'][$basket_position]; $oldprice=$_SESSION['ses_basket_price'][$basket_position]; $newprice=($oldprice/$oldamount)*$amount; $_SESSION['ses_basket_price'][$basket_position]=$newprice; }else{ $_SESSION['ses_basket_name'][]=$_GET['basket']; $_SESSION['ses_basket_amount'][]=1; $_SESSION['ses_basket_price'][]=$_GET['price']; $_SESSION['ses_basket_id'][]=$_GET['id']; $_SESSION['ses_basket_items']++; } }else{ $_SESSION['ses_basket_items']=1; $_SESSION['ses_basket_name'][0]=$_GET['basket']; $_SESSION['ses_basket_amount'][0]=1; $_SESSION['ses_basket_price'][0]=$_GET['price']; $_SESSION['ses_basket_id'][0]=$_GET['id']; session_register("ses_basket_items"); session_register("ses_basket_name"); session_register("ses_basket_amount"); session_register("ses_basket_price"); session_register("ses_basket_id"); } } if ($_SESSION['ses_basket_items']>0){ for ($basket_counter=0;$basket_counter<$_SESSION['ses_basket_items'];$basket _counter++){ // basket output $price=sprintf("%01.2f",$_SESSION['ses_basket_price'][$basket_counter]); $amount=$_SESSION['ses_basket_amount'][$basket_counter]; $name=$_SESSION['ses_basket_name'][$basket_counter]; $aaa=$basket_counter; echo "$amount $name $price"; echo "<a href=\"2.php?action2=deleteItem&position=" . $aaa .
