Magento 1.8 - 以编程方式添加优惠券代码

Question

I want to have a Model Window on my website in which the user can sign up to our newsletter. Once the user has entered their email address and successfully subscribed I want to automatically add the coupon code to their cart.

I have the following script, but when I run it and refresh my cart, it doesn't add the discount:

<?php

  require_once 'app/Mage.php';
  umask(0);
  Mage::app();

  Mage::getSingleton('checkout/cart')->getQuote()->setCouponCode('ks92yor7')->collectTotals()->save();

?>

What am I missing?

Thanks

Answer 1

I needed to set the core/session to frontend.

After Mage:app();:

Mage::getSingleton('core/session', array('name'=>'frontend'));
