pmprosm_discount_code.php

/*
	Override the discount code given to sponsored members.
	This recipe makes any sponsored members with level 2 expire in 2 days.
	
	The 'discount_code' array supports the following attributes:
	code_id, level_id, initial_payment, billing_amount, cycle_number, cycle_period, billing_limit,
	trial_amount, trial_limit, expiration_number, expiration_period

	Make sure that strings in the _period values are wrapped in single quotes, e.g. 'expiration_period' => "'Year'"
