Dynamic Attribute Examples

  • How to set output Google Shopping acceptable values for gender: male, female, unisex

    Google accept only one of three values for gender: male, female, unisex. Your merchant store may have another values for gender.
    For example, gender values: Mens and Womens. To replace these values, we create two conditions and set appropriate output values for genders. If product don't have gender "Mens" or "Womens" attribute values, it will have Default Value - unisex.

  • An example of why position of the conditions must be set correctly.

    In this dynamic attribute for the Silver color we need to set ouput value Matte Silver. For all other colors, we need to set ouput value Multi.
    If you set conditions with the same order posiotions as at this image, then this dynamic attribute will not work correctly!
    First Condition: Color is not empty will replace all existent Colors to value Multi(including color Silver). So when second Condition search for Silver color, it will not find any values.
    To make it work correctly, you need to change position of the conditions. dynamic_color.png

Dynamic attribute examples with Subconditions

~! If you use subconditions, all selected conditions will be applied at the same moment

  • For the AMD brand products, which have price between 200 and 500, we need to set ouput price with 20% discount.

    To cover all requirements, we need to use Subconditions.
    Select AMD manufacturer and add two subconditions: Price equals or greater than 200 and Price equals or lower than 500.
    To get 20% price discount at the Output value, we used one of the php patterns{(return ($price*0.8);)}. For more examples and information about patterns, see List of Patterns

    You can add in this dynamic attribute discount for another price limits. To do this, you need to add a new Condition with subconditions. (See next example)
