Creating Cart Rule with Product Restrictions

[smallbizwiz]

In a module, I need to create a cart rule that contains product restrictions.

 

I can see that we set $cart_rule->product_restriction to 1 to indicate there is a product restriction fro the cart rule.  How do we take the next step to indicate the actual products/categories that are included in the restriction?  

 

That is, after executing $cart_rule->add(), how does the cart rule know what restriction to apply exactly?

 

I would assume we pass an array of types and IDs to a function that will do this????

 

I could certainly use brute force to insert data into cart_rule_product_rule, cart_rule_product_rule_value and cart_rule_product_rule_group tables, but there has to be a systematic way to do this in PS.

 

Help!!!!

 

Thanks guys,

Teo

Simple way :

1- your customers must create one or more cart rules

2- select one of available cart rules in admin of your module

3- your module will work with selected item settings (restrictions , ...)

 

Hard way : 

you must check admincartrulecontroller and cartrule class, then use their methods to create cart rules with some restrictions
