ich habe einen einfachen Warenkorb gefunden, den man sicher leicht in Contenido integrieren kann.
Es handelt sich dabei um den freien Warenkorb: Webforce Cart (www.webforcecart.com). Dieser Warenkorb besteht eigentlich nur aus zwei Dateien, eine für die Ausgabe und eine für die Verarbeitung.
Hier der Code für die Ausgabe, den man als Modul anlegen kann:
Code: Alles auswählen
<?php
// wfCart Demo
// You must included wfcart.php BEFORE you start the session.
include "wfcart.php";
session_start(); // start the session
$cart =& $_SESSION['wfcart']; // point $cart to session cart.
if(!is_object($cart)) $cart = new wfCart(); // if $cart ( $_SESSION['cart'] ) isn't an object, make a new cart
// end of header stuff
?>
<h3>wfCart Demo</h3>
<?php
// Usually you would get your products from a database but we'll pretend..
$products = array();
$products[1] = array("id"=>1,"name"=>"A Bar of Soap","price"=>2.00);
$products[2] = array("id"=>2,"name"=>"Shampoo","price"=>4.80);
$products[3] = array("id"=>3,"name"=>"Pizza","price"=>12.95);
// check to see if any items are being added
if($_POST['add']) {
$product = $products[$_POST['id']];
$cart->add_item($product['id'],$_POST['qty'],$product['price'],$product['name']);
}
if($_POST['remove']) {
$rid = intval($_POST['id']);
$cart->del_item($rid);
}
// spit some forms
// You can have many different types of forms, such as many quantity boxes
// and an "add to cart" button at the bottom which adds all items
// but for the purposes of this demo we will handle one item at a time.
echo "<table>";
foreach($products as $p) {
echo "<tr><td><form method='post' action='demo.php'>";
echo "<input type='hidden' name='id' value='".$p['id']."'/>";
echo "".$p['name'].' $'.number_format($p['price'],2)." ";
echo "<input type='text' name='qty' size='5' value='1'><input type='submit' value='Add to cart' name='add'>";
echo "</form></td></tr>";
}
echo "</table>";
echo "<h2>Items in cart</h2>";
if($cart->itemcount > 0) {
foreach($cart->get_contents() as $item) {
echo "<br />Item:<br/>";
echo "Code/ID :".$item['id']."<br/>";
echo "Quantity:".$item['qty']."<br/>";
echo "Price :$".number_format($item['price'],2)."<br/>";
echo "Info :".$item['info']."<br />";
echo "Subtotal :$".number_format($item['subtotal'],2)."<br />";
echo "<form method=post><input type='hidden' name='id' value='".$item['id']."'/><input type='submit' name='remove' value='Remove'/></form>";
}
echo "---------------------<br>";
echo "total: $".number_format($cart->total,2);
} else {
echo "No items in cart";
}
?>

Leider sind meine PHP-Künste sehr rudimentär
Bitte helft mir doch, den Warenkorb zu integrieren, das ist bestimmt für viele hier interressant und leicht nachzuvollziehen.
Danke und viele Grüße,
Tom
Schein also daran zu liegen, dass die session nicht mit übergeben wird.
