Why not replace the foreach and if combo inside the while with:

false ) {

If list() works for you it's fine. I don't really use it so not entirely
sure of it's functionality with respect to looping.

Re: [PHP] session_name("CCLTrolley")
In the search results, I use something longwinded:
You are talking about doing this, below. It looks a little clunky,
doesn't it?
foreach ($_SESSION['TrolleyContents'] as $value) {
$sql = "select * where RNum= $value";
$news = mysql_query($sql1) or die ...
while ($mydata = mysql_fetch_object($news))
{
echo "$mydata->RNum - $mydata->field1: $mydata->field2.";

When I create viewcart.php, what is the best way to extract and display
the contents of $_SESSION['TrolleyContents'] ?
Do I use my $sql value?
or in my while statement where
$mydata->RNum = $_SESSION['TrolleyContents'][??]] echo $mydata->RNum,

Do I implode or explode $_SESSION['TrolleyContents']?
Use "foreach" to traverse the array and display each trolly entry nicely
(probably as you do in the search results).

Yep the frankensteinian version should work fine if you never want a quantity greater than one, I was just trying to head off problems before they occurred, but confused the issue since you don't need quantities :) I took a look at your link and it appears to be working fine, though you haven't yet wired up the viewcart.php page :) Cheers, Rob. -- .. | InterJinn Application Framework - http://www.interjinn.com | :: | An application and templating framework for PHP.

The expression:

$trolley[$item] = $trolley[$item] - $quantity;

"isset" checks that the item with ID $item is in the trolley. No need to
decrease the quantity if it's not there.

If there are 0 or less items then there's no point having 0 of the item
in the trolley, so we unset the item from the array, which essentially
removes it completely. To view the difference at each step you can do
the following:
";
trolleyPrint();
$trolley[$item] -= $quantity;
echo "Trolley after removing $quantity of $item";
trolleyPrint();

I thought I had? Haven't I?
But this is the easiest shopping cart I have ever seen.
However, I still have not understood what you were doing with these
lines I commented out.
if( isset( $_SESSION['TrolleyContents'][$_POST['RNum']] ) )

If you go with an array system might I suggest the following change to

[PHP] session_name("CCLTrolley")
$TrolleyContents is a string. Basically what I want to accomplish here is if $TrolleyContents already exists append $AddToTrolley to $TrolleyContents, if not register $TrolleyContents. Am I going about it right? John -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
