How to add a product with custom options into Magento shopping cart from an external site?

This is a follow up post to a previous article I wrote on how to add products into Magento but this time the script includes custom options (attributes) of the product. I used Magento version 1.4.0.1 in this example. Just copy the whole script and save it as index.php.

<?php
require_once ("/var/www/your-magento-directory/app/Mage.php");
umask(0);

// Initialize Magento
Mage::app("default");

// You have two options here,
// "frontend" for frontend session or "adminhtml" for admin session
Mage::getSingleton("core/session", array("name" => "frontend"));

// get the current Magento cart
$cart = Mage::getSingleton('checkout/cart');

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']);

	// start adding the product
	// format: addProduct(<product id>, array(
	//         'qty' => <quantity>,
	//         'super_attribute' => array(<attribute id> => <option id>)
	//     )
	// )
	$cart->addProduct($product, array(
			'qty' => $_POST['qty'],
			'super_attribute' => array( key($_POST['super_attribute']) => $_POST['super_attribute'][525] )
			)
		);

	// save the cart
	$cart->save();

	// very straightforward, set the cart as updated
	Mage::getSingleton('checkout/session')->setCartWasUpdated(true);

	// redirect to index.php
	header("Location: index.php");

}else{
?>
<html>
<head></head>
<body>
<div style="width: 400px; margin: auto">
	<h3>Very Nice T-shirt</h3>
	<hr>
	<div style="width: 180px; margin:auto; line-height: 30px">
		<form action="index.php" method="post">
			Size:
			<select name="super_attribute[525]">
				<option value="">Choose an option...</option>
				<option value="100">Small</option>
				<option value="99">Medium</option>
				<option value="98">Large</option>
			</select><br>
			Quantity: <input type="text" name="qty" size="1" value="1">
			<input type="submit" name="submit" value="Add This">
			<input type="hidden" name="product" value="119">
		</form>
	</div>
	<hr>
	<strong><?php echo "Cart Qty: ".$cart->getItemsQty();?></strong>

      You have to do the programming based on your need.

    Very nice! I think this covers what Ive been looking for. Can we also pass form entries to the Magento cart?
    I would like to have a mini-form in wp that on submit auto populates the corresponding fields in onepage checkout, allowing users to complete the order. Is this possible?

      Yeah it should allow you to do that. What are the fields that you plan to add from an external page?

        I have an external page where I’m selling one bottle of a weight loss product.
        The form consists of:
        First Name
        Last Name
        Address
        City
        State
        Zip
        Country
        Email
        Phone

        Submit would auto populate those fields in magento checkout, allowing users to complete the form and submit payment.
