Definitions

• Field – is used to get user’s input on the woocommerce product page. Custom Field can be used to calculate the price (is used in formula)

• Fieldset – store manager can create the fieldset (set of custom product fields) which consists of different Fields. Fieldset must have at least one Field and the expression (formula) to calculate the product price

• Expression/Formula – mathematical and/or logical expression using to calculate the woocommerce custom price. The expression can be single-line, conditional price addons (product addons). Expression is protected and calculated only server-side.

• Validation – each Field has specific requirements to be met. Incorrect values make it impossible to calculate the woocommerce custom price and add the product to the cart.

• Global Parameters – are numeric variables which can be used in formulas across all fieldsets.
