Hello all, ive built a dynamically rendering custom cart for use with paypal but now need to convert if for use with authorize.net. All the information is gathered into one form but Im having trouble itemizing and sending all information (item_id, description, price, quantity, total) for multiple products to the payment gateway using SIM.
Any help would be greatly appreciated. Thanks!
paypal code:
<?php
// Render Cart for View
$cartOutput = "";
$cartTotal = "";
$pp_checkout_btn = '';
$product_id_array = '';
if(!isset($_SESSION["cart_array"]) || count($_SESSION["cart_array"]) < 1) {
$cartOutput = "<h2 align='center'>Your Shopping Cart is Empty</h2>";
} else {
//Start PayPal Checkout Button
$pp_checkout_btn .= '<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="upload" value="1">
<input type="hidden" name="business" value="name@example.com">';
//Start the For Each Loop
$i = 0;
foreach ($_SESSION["cart_array"] as $each_item) {
$item_id = $each_item['item_id'];
$sql = mysql_query("SELECT * FROM products WHERE id='$item_id' LIMIT 1");
while ($row = mysql_fetch_array($sql)) {
$product_name = $row["product_name"];
$price = $row["price"];
}
$subtotal = $price * $each_item['quantity'];
$cartTotal = $subtotal + $cartTotal;
setlocale(LC_MONETARY, "en_US");
$subtotal = money_format("%10.2n", $subtotal);
// Dynamic Checkout Btn Assembly
$x = $i + 1;
