ecart

How we allow validation on ecart button . I want to validation for quantity of stock . when we click on add to cart button validation check that quantity is not greater than stock quantity

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:

<?php

if (isset($_POST['WA_Store_Cart_1_Quantity_Add']) && isset($_POST['QuantityOnHand'])) {

    if($_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 } ?>
