Andras,

input type=hidden name=item[] value=applesApples input type=text
name=qty[] value=0 input type=text name=price[] value=0

Will get you where you need to go on the HTML side of things, then on
the back end you need to process each array.  By setting a default value
of 0 for the qty, you force users to change the values, but you also
keep your arrays intact and easier (IMHO) to deal with.

 Any help is appreciated..

Wolf,

The tip worked great !! All working as expected now...

$listvals=$_POST['item'];
$n=count($listvals);
$i=0;
while ( $i  $n )  {
if ($qty[$i]  0) {
AddItem($item[$i], $qty[$i]);
UpdatePrice($item[$i], $price[$i]);
}
$i++;
}

Thanks,

a useful addition can be to use the item id in the 'key' of the input names
(and always quoting your element attributes is highly recommended):

input type=hidden name=item[18] value=applesApples input type=text
name=qty[18] value=0 input type=text name=price[18] value=0

that way you can easily fish out the quantities when looping the
selected items (example mostly ignores input cleaning/validation for brevity 
etc -
but you shouldn't :-) e.g. get anal about make sure things are actually 
integers when
that is what you require, etc):

foreach ($_POST['item'] as $itemId = $itemName) {
if (isset($_POST['item'][$itemId])  ($qty = 
intval($_POST['item'][$itemId])) {
addItem($itemId, $qty);
}
}

another thing that popped into my head was the fact that it's
probably not intended behaviour to allow the customer to determine the
unit price of an item -
but if it is then can I have 10 Plasma Screens at 1 dollar a pop? ;-)

Yes, when I generate my cart I use the itemID as a key field (since the
ID stayed the same but the # in the database could change).

And ALWAYS quote your inputs in HTML.  It makes for a lot less
headaches.  But then I wasn't sending COMPLETE code, just enough to get
him on the right track. :)

We should all be using the guidelines within http://phpsec.org/ to keep
good coding practices.

I too need the screens at 1 dollar (52 Wide-screen format please) as
well as the 6-person hot-tub and deck combo.
