Hi @apollo24,
My question is how to detect a custom field of Featured image?
Is this a custom featured image field added by another plugin/theme? If so, these instructions should work: http://www.wpallimport.com/documentation/custom-fields/theme-plugin-fields/.
If I misunderstood, can you please elaborate and show me a screenshot of the field you’re trying to detect?
I mean default WordPress featured image, aslo called Thumbnail
Hey @apollo24,
Thanks for clarifying. We actually intentionally disable auto-detecting that field – instead of importing directly into it, you should just use the “Set the first image to the Featured Image (_thumbnail_id)” option in the “Images” section of the import.
If you really need to import directly into the featured image custom field, then you can just type in “_thumbnail_id” in the custom fields section.
