#1: Array / form processing

Posted on 2010-10-07 21:35:32 by ron.piggott

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

if ( $gift_certificate == "yes" ) {
$gift = 1;
} else {
$gift = 2;
}

$_SESSION['life_coaching_order'][$product][$gift]['quantity' ] =
$_SESSION['life_coaching_order'][$product][$gift]['quantity' ] + 1;
===

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.

....

foreach ($_SESSION['life_coaching_order'] AS $coaching_fee_theme_reference

In this example $value would be an array. To test if it is a gift or not you
would do this from within the foreach loop:

//gift
if ( isset($value[1]) && isset($value[1]['quantity']) )
{
$gift_quantity = $value[1]['quantity'];
}

//personal use
if ( isset($value[2]) && isset($value[2]['quantity']) )
{
$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.

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.

<input type="submit" name="submit" value="Remove" class="place_order"/>

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.

<input type="submit" name="submit" value="Remove" class="place_order"/>

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.

<form target="..." action="...">
<input type="hidden" name="submit" value="Remove" />
<input type="hidden" name="product_so" value="1234" />
<input type="submit" value="Remove" class="place_order"/>
</form>


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;

const ORDER_GIFT=1;
const ORDER_PERSONAL=2;

function getGift() {
return $this -> gift;
}
}

using

$_SESSION['life_coaching_order'][] = new Order();

foreach ( $_SESSION['life_coaching_order'] as $order )
{
switch ( $order -> getGift() )

case ORDER_GIFT: break;

case ORDER_PERSONAL: break;

}

I hope that will help you,

Sebastian
