I was wondering how to import CSV posts with custom fields.
For example, I looked into table "postmeta" and each field contain two meta_key. I have a custom field called "coupon_code" and I also see ACF generates another coupon_code with "_coupon_code" with some value "field_iudi3weiie9".
What and how is this "field_deiidisee" generated? If I want to import posts with those fields via CSV. Do I need to add both "coupon_code" and "_coupon_code" in order for ACF to recognized the "coupon_code" field?
Your help is appreciated.
