this will take a little hand coding to do.

1) Add a hidden form element to the add to cart form to store the available quantity, name it "QuantityOnHand"

2) Make note of the quantity form elements name. For sake of example, I will use "WA_Store_Cart_1_Quantity_Add"

3) Add the code at the top of the page:


if (isset($_POST['WA_Store_Cart_1_Quantity_Add']) && isset($_POST['QuantityOnHand'])) {
$_POST['WA_Store_Cart_1_Quantity_Add'] > $_POST['QuantityOnHand']) {
header("location: "$_SERVER['PHP_SELF']."?qty=toMany");

This will redirect the page back to itself if they enter to big a value in the Quantity.

you can use this code to show an error message if you like:

<?php if(isset($_GET['qty']) { ?>

Your error message here
<?php ?>
