NEW JAVASCRIPT CODE | PayPal Discount Code

Project: PayPal Discount Code

JavaScript PayPal 'Discount Code' for Wojo Groups SimpleCart.js

A working script that will apply (In this Case) a 10% Discount on all cart items after the user/customer clicks the 'Checkout' button.

I used and modified Zubrag.com's "Web Page Password Protect" for entering the discount code. Please visit www.zubrag.com on items/instructions of its uses.

Find this Line in the simpleCart.js (Version = '2.2.2')

form.appendChild( me.createHiddenElement( "amount_" + counter, item.price ) );

And Modify it to This

form.appendChild( me.createHiddenElement( "amount_" + counter, this.currencyStringForPaypalCheckout( (item.price)* discount ) ) );

 

I should also mention that for the Discount Code Entry Page; I used ''Web Page Password Protect'' from www.zubrag.com

 

A few notes:

Pay close attention to the ''cart.php'' and the ''cart_discount.php'' files; in particular the cart.php file's include statement:

<?php include("/home/uswsc3/public_html/discount_example/cart_discount.php"); ?>

To find your relevant path (like the one above) use the following syntax:
http://www.yourdomain.com/cart_discount.php?help

Will continue to redirect to ''cart_discount.php'' page until the correct ''Discount Code'' is entered.

Once the correct ''Discount Code'' is entered however, the redirect no longer exist and the ''cart.php'' page is loaded. This is where the 10% Discount cookie is set.

The code uses two (cookies) to operate.

''discount'' cookie sets the 10% (.9) Discount.

''verify'' verifies the discount was set to .9

All cookies (including the simpleCart cookies) have been set to 1 day (24 Hours).
