Criteria
This section describes the concepts of criteria.
Overview
Criteria are a central concept of LFS and are used on several places in order
to restrict or display information on base of the current situation. For
example: which products are in the cart or in which country are these products
about to be delivered. Criteria have a value and an operator, which are the base
whether the criteria is true or false. This is described in more detail in the
section Criteria below.
Criteria are used within:
- Payment methods
- Payment method’s prices
- Shipping methods
- Shipping method’s prices
- Discounts
For example a shipping method is only available when all of its criteria are
true.
Criteria
This paragraph describes the existing types of criteria and which operators they
provide.
Cart Price
Description
Tests the gross price of all products within the cart (without costs for
shipping, payment and so on).

entered value.

- The criterion is true, if the gross cart price is less than the entered
value.
- Less than equal to
- The criterion is true, if the gross cart price is less than or equal to
the entered value.
- Greater than
- The criterion is true, if the gross cart price is greater than the entered
value.
- Greater than equal to
- The criterion is true, if the gross cart price is greater than or equal to
the entered value.
Payment Method
Description
Provides some tests for the payment methods of the shop.
Value
Any selection out of all provided payment methods.
Operators

value.

entered value.
Height

is greater than the entered value.
- Greater than equal to
- The criterion is true, if the total height of all products within the cart
is greater than equal to the entered value.

is less than equal to the entered value.
- Greater than
- The criterion is true, if the maximum length of all products within the cart
is greater than the entered value.
- Greater than equal to
- The criterion is true, if the maximum length of all products within the cart
is greater than equal to the entered value.
Weight
Description
Tests the total weight of all products within the cart.

is less than equal to the entered value.
- Greater than
- The criterion is true, if the total weight of all products within the cart
is greater than the entered value.
