I am writing a custom shopping cart that eventually the "cart" will be
uploaded to PayPal for payment. I need to be able to include the option
that the purchase is a gift certificate.
At present my "add to cart" function goes like this:
===
# Gift Certificate: 1 is a gift; 2 is personal use
Now I need to display the shopping cart contents. I want to do this
through an array as the contents of the shopping cart are in a session
variable. I start displaying the shopping cart contents by a "FOREACH"
loop:
===
foreach ($_SESSION['life_coaching_order'] AS $coaching_fee_theme_reference
=> $value ) {
===
What I need help with is that I don't know how to test the value of $gift
in the above array if it is a 1 or 2 (which symbolizes this is a gift
certificate).
I have something like this in mind:
if ( $_SESSION['life_coaching_order'] == 2 ) {
But I don't know how to access all the components of the array while I am
going through the FOREACH loop.
By using a "1" or "2" I have made gift certificates their own product. If
you a better method I could use please provide me with this feedback.

{
$personal_quantity = $value[2]['quantity'];
}
Technically the above IF's are optional, but they are proper syntax.
I don't know how you are with OOP, but you may have more luck using objects
instead of a complex array.

Re: Array / form processing

Many thanks, Chris.
I have one additional question about this shopping cart project. I need
to make a submit button for the purpose of removing an item from the
shopping cart.
What I am struggling with is to find an effective method for passing the
product serial number (auto_increment in the table it is stored in) so I
know which product the user is removing from their purchase. Then I will
just unset the session variable that matches.
What are your suggestion(s)?
Thank you your help with my original question Chris.

I don't know what the context is like, but you may be better off just using
an entire form here with hidden fields. i.e.
Without knowing what else is going on in your page, and how the request is
being handled on the server, it's kind of hard to give exact advice. :)

First at all, I wouldn't use 1 or 2 for defining important informations.
use something like
define('ORDER_GIFT', 1);
define('ORDER_PERSONAL',2);
If you want to check all values of your array you can use several
foreach loops like
foreach ($_SESSION['life_coaching_order'] AS $coaching_product => $tmp_array)
{
foreach ($tmp_array as $coaching_gift => $tmp_array2)
{
switch ($coaching_gift)
case ORDER_GIFT: break;
case ORDER_PERSONAL: break;
)
}
}
Personally I would prefer writing a class like
class Order
{
private $product;
private $gift;
private $quantity;
