Ouch… It seems to be difficult to me… Could you please give me a small example 🙂 ?
I've tried with the plugin : WP Ultimate CSV Importer. I was allowed to choose the custom post type and allowed to map my csv cells with the good custom field (for example : “CF:address”). It creates my company but only with post_title and post_content, nothing else.
After that I've seen that the plugin allow to assign a cell to a custom field with let me assign the name of the field. I have tried with “address” instead of the suggested “CF:address” and it works well.
But I still have a problem. I've checked in WPUF settings to “Show custom fields on post content area”. So normally on a single company page, it has to list the custom fields, but it doesn't ! When I edit one of these companies, I have to chose the “WPUF Form”, then update the post, and finally it works. But as I said, I have 150 companies and don't want to edit each one by one.
So when I import my companies, do I have to assign a value to a specific field to let it know that it has to use the right form ?
