README

This module gives the ability to define promotions with a set of requirements that add themselves to purchases, based on these rules. Each promotion can have a static or dynamic/configurable amount.

Promotions can also have ontime or multiple time uses for promo_codes

Usage

Add a behavior to the purchase and brand_purchase models:

class Model_Brand_Purchase extends Kohana_Model_Brand_Purchase {

	public static function initialize(Jam_Meta $meta)
	{
		parent::initialize($meta);

		$meta
			->behaviors(array(
				'promotable_brand_purchase' => Jam::behavior('promotable_brand_purchase'),
			));
	}
}
// ...
class Model_Purchase extends Kohana_Model_Purchase {

	public static function initialize(Jam_Meta $meta)
	{
		parent::initialize($meta);

		$meta
			->behaviors(array(
				'promotable_purchase' => Jam::behavior('promotable_purchase'),
			));
	}
}

And you'll need to add actual promotions to the database. The promtion modle uses single table inheritence to have a different class for each promotion. Each of these has to define "applies_to" and "price_for_purchase_item" which your promotions will have to implement. There is also the Model_Promotion_Promocode class which gives the promotion the ability to use promo codes which exhaust themselves when are used.

There are 2 availbale predefined promotions:

• Model_Promotion_Promocode_Giftcard - to use it you'll need to enter requirement - the minimum price where the promotion applies, and amount - the amount (Jam_Price) to be reducted from the purchase
• Model_Promotion_Promocode_Percent - get a static reduction of some percent (amount). Amount is a value from 0 to 1.

promo_code_text

The promotable_purchase behavior adds a promo_code_text field to the purchase (its not in the database). When you set a promocode to this field it would try to find it, and then run "validate_purchase" of the appropriate promotion, if found. If everything checks out, the promotion associated with this promocode will be added to the purchase.
