Coupon Code

You’ll need to login to www.paypal.com to create your hosted buttons.

• Create a buy now button at full price and use that as your default hostedButtonId by assigning it to the $hostedButtonId variable.
• Set The default full price by assigning it to the $amount variable this should match the price for the button you just created at paypal.com
• Create additional buttons at www.paypal.com and apply discounts through the HTML Variables. See our screencast on how to apply discounts with HTML variables.
• Add the hostedButtonIds for the discount button to the array. Also, add the discount amount.
• Note, this example is using a fixed discount amount.
• If you want to use a percentage discount, update this code $amount = ($amount – $discount) to $amount = ($amount – ($amount * .$discount));

<?php

	$hostedButtonId = "";
	$amount = 0;

	$arr = array(
	"take5" => array("hostedButtonId" => "", "discount" => "5"),
	"take10" => array("hostedButtonId" => "", "discount" => "10")
	);

	foreach ($arr as $key => $value) {

		if ($key == $_POST["couponCode"])
		{
			$hostedButtonId = $value["hostedButtonId"];
			$discount = $value["discount"];
			$amount = ($amount - $discount);
			break;
		}
	}

?>
