Thanks for the fast reply.
I use the plugin
https://codecanyon.net/item/woocommerce-custom-fields/11332742
There I have created a product text field. Unfortunately this is not found under the custom fields (Restriction Tab).
This text field gets filled by a datepicker with a date (format dd.mm.yyyy). Now I would like to use a different coupon depending on the date.
The plugin documentation says the following about the field structure
https://support.rightpress.net/hc/en-us/articles/115001968923-Developers-Field-data-storage-structure
Extract from the support page:
Product Fields:
Meta key Meta value Location
_wccf_pf_{key} field value in order item meta
_wccf_pf_id_{key} field id in order item meta
If I take the custom field in the RestrictionTab with the value “_wccf_pf_{mykey}” and the date as condition, should this work?
Thanks.
Stefan
