I have used magento many times, but this is the ultimate challenge. Im working on a magento store which has over 400,000 products - each with its own variation / product options. Hundreds of products are added and removed daily on our master store (which is based on a custom shopping cart system and runs on MSSQL).

I have configured magento to grab all the categories, products, text, descriptio, prices, variations etc and create the product pages dynamically on the fly e.g <http://www.offices-furniture.co.uk/pp?prod=mercury-reception-unit.html>

The problem is I now need to be able to add these products to the shopping cart without them physically existing in the back end. I have added one product to the back end and plan to use this as a GENERAL template type product, so its always this product (variations of it) that get added to the cart e.g

<http://www.offices-furniture.co.uk/frodo.php> but I cannot for the life of me get the price to change.... grrrr..

If anyone could point me in the right direction on how to change the price via HTML or PHP on the front end and post it to the shopping cart without changing the price on the back end

Thanks in advance all…

Here is the code i’ve tried using to change the price;

```
    <?php
require_once ("app/Mage.php");
umask(0);

Mage::app("default");

Mage::getSingleton("core/session", array("name" => "frontend"));

// get the current Magento cart
$cart = Mage::getSingleton('checkout/cart');
$product = Mage::getModel('catalog/product');
$product->setCustomPrice(99);
$product->setOriginalCustomPrice(99);
$product->getProduct()->setIsSuperMode(true);
$product->setTypeId('configurable');
$product->setTaxClassId(1); //none
$product->setSku(ereg_replace("\n","","videoTest2.2"));
$product->setName(ereg_replace("\n","","videoTest2.2"));
$product->setDescription("videoTest2.2");
$product->setPrice("129.95");
$product->setShortDescription(ereg_replace("\n","","videoTest2.2"));
$cart->save();

if(isset($_POST['submit'])){

// call the Magento catalog/product model

$product = Mage::getModel('catalog/product')
// set the current store ID
->setStoreId(Mage::app()->getStore()->getId())
// load the product object
->load($_POST['product']);
*/
