Rules

hexfusion has been busy building Rules. This page is for ideas and requirements.

Requirements:

• conditions can included comparison to current date (rules can change from one day to another)
• possible to match more than one rule and produce a result for every matched rule
• must have priority so that rules are compared in a fixed order but priority does not have to be unique
• can specify a rule as LAST
• rule result is some other referenced object (tax/shipping/..)
• lots of Moo :-)
• rule can modify input args
• rule can force a jump back to the start of the rule list (RESET/RESTART?)
• rule can specify things like $zone->has_country($args->{supplier_country})
• coupons
• discounts based on delivery of service on future date (pay 8 +weeks before course for discount)
• product combination discounts: buy B with A and get 5% off A
• would be cool to be able to use coderefs for really weird conditions

SysPete's old TaxRules

• Example of multi level rule data output from find_rule_components. This should support multiple levels for all rule components.
