array question

how can I make this work? I have posted the whole function, but I want to run this code

echo '
	<input type="hidden" name="item_name_'.$row.'" value="'.$title.'"/>
	<input type="hidden" name="item_description_'.$row.'" value="A completly handmade diaper cake with elegant decorations"/>
	<input type="hidden" name="item_quantity_'.$row.'" value="'.$qty.'"/>
	<input type="hidden" name="item_price_'.$row.'" value="'.$price.'"/>';

for each item that is in my cart. Needless to say I can't figure it out. Somebody help please!

function showCart() {
global $db;
$cart = $_SESSION['cart'];
if ($cart) {
	$items = explode(',',$cart);
	$contents = array();
	foreach ($items as $item) {
		$contents[$item] = (isset($contents[$item])) ? $contents[$item] + 1 : 1;
	}
	$output[] = '<form action="cart.php?action=update" method="post" id="cart">';
	$output[] = '<table width="500px" style="border:1px solid #EEEEEE;">';

	foreach ($contents as $id=>$qty) {

What I want is for the first block of code to print in the form for every item in the cart. Ex: say there is 5 items in the cart I want this first block of code to print 5 times in the form.

ballhogjoni · July 10, 2007

wow I can't believe I stumped everyone!

I would suggest the problem lies in your lack of description.

ballhogjoni · July 10, 2007

Ok I am going to try and describe this the best that I can. I want the variable $item_num to increment every time this code is ran. The reason for this is because the user may have more than one item in their shopping cart and this foreach loop displays each item name, description, quantity, & price. Google checkout which is what I am going to use once I get it working, requires each item to have a different number for the item name, item description, item quantity, & item price. Example: the first item would be: item_name_1, item_description_1, item_quantity_1, item_price_1

the second item would be: item_name_2, item_description_2, item_quantity_2, item_price_2

the third item would be: item_name_3, item_description_3, item_quantity_3, item_price_3

etc...

foreach ($contents as $id=>$qty) {
		$sql = 'SELECT * FROM products WHERE id = '.$id;
		$result = $db->query($sql);
		$row = $result->fetch();
		extract($row);
		$output[] = '<input type="text" name="item_name_'.$item_num.'" value="'.$title.'"/>';
		$output[] = '<input type="text" name="item_description_'.$item_num.'" value="A completly handmade diaper cake with elegant decorations"/>';
		$output[] = '<input type="text" name="item_quantity_'.$item_num.'" value="'.$qty.'"/>';
		$output[] = '<input type="text" name="item_price_'.$item_num.'" value="'.$price.'"/>';	
	}

So....

<?php
$item_num = 0;
foreach($contents as $id=>$qty) 
{
         $item_num++;

           // other code
}

?>

.. that's what you want?
