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

Subject:  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--;
