How can we validate coupon code on a custom form on wishlist page? Is there any way to check the validity of the coupon code with ajax functionality?
I have used the following code, but it always return valid message:
$codeLength = strlen($couponCode); // $couponCode is the coupon code entered by the user.
$isCodeLengthValid = $codeLength && $codeLength <= Mage_Checkout_Helper_Cart::COUPON_CODE_MAX_LENGTH;
if (!Mage::getSingleton('checkout/cart')->getQuote()->getItemsCount()) {
exit('No items in cart');
}
Mage::getModel('checkout/cart')->getQuote()->getShippingAddress()->setCollectShippingRates(true);
Mage::getModel('checkout/cart')->getQuote()->setCouponCode($isCodeLengthValid ? $couponCode : '')
->collectTotals()
->save();
if ($codeLength) {
if ($isCodeLengthValid && $couponCode == Mage::getModel('checkout/cart')->getQuote()->getCouponCode()) {
$msg = 'Coupon code applied';
} else {
$msg = 'Coupon code is not valid';
}
} else {
$msg = 'Coupon code was canceled.';
}
Simply, I have tried on cart items on ajax page. But it didn't work. I am a newbie in magento. Any help appreciated..
