Hi @mishtershmart

The field key is a unique identifier for the field object. ACF uses this field key to link the value saved on a post back to the field object.

ACF can’t use the field’s name, as there could be 2 or more fields with the same name.

The field key must be unique and just not change on each page load (cannot be dynamically generated on the fly).

Thanks
