Re: [PHP] Help with a foreach statement

Hi Ron,

This code should work:

<?php

$path_to_shopping_cart = './';
$iLength = count($cart);

foreach ($cart as $product_name => $quantity)
{
echo "<li><a href=\"" . $path_to_shopping_cart . "product/" .
$cart[$product_id] . "/\">" . $product_name . "</a> - " . $quantity .
"</li>\r\n";
}

?>

Though I'm not sure about $cart[$product_id]. Where is that coming
from?. It makes no sense here. Perhaps you want to do a
tri-demensional array in $_session, so you will have a
dual-demesnional array in $cart.

Let me know,

I am writing a shopping cart.

Products assigned in the following fashion:
$_SESSION['selection'][$product]=$quantity;

I am wanting to display the list of products in the shopping cart in a
list for the user to see as they continue shopping.

I put the SESSION variable into $cart

$cart = $_SESSION['selection'];

then I start the foreach and this is where I get messed up. I am trying
to ECHO the following syntax to the screen with each selected product:

The part I need help with is to write the foreach loop to give me
$product (so I may query the database to find out the product name) and
the $quantity (so I may show the user what they are purchasing). The
part that is messing me up is that this is an array.

My ECHO statement should look like this:

echo "<li><a href=\"" . $path_to_shopping_cart . "product/" .
$cart[$product_id] . "/\">" . $product_name . "</a> - " . $quantity .
"</li>\r\n";
