Re: Array / form processing

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. Ron The Verse of the Day Encouragement from God's Word www.TheVerseOfTheDay.info 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;
  }
