I have a MB custom post type with MB custom fields. The post title is the regular WP Title field. The custom fields data are saved to a MB custom table.
I tried today to import simple text data using WPAI. But WPAI didn't detect any of the custom fields (I had manually saved data before to the post type). So I wrote the column names myself. The import seemed to work well - no complains from WPAI. The new posts are created. BUT no new data shows up in the custom table.
All custom fields data are saved to the postmeta table instead of the custom table! So is the case that if I use a custom table to store data, MB and WPAI will not work together at all? I know that MB does not support WPAI yet, but was under the impression (after reading other topics in this forum) that it should at least work with simple (text) fields.
Do you have a solution right now for this problem? Something like this suggestion for ACF: https://wordpress.org/support/topic/import-custom-fields-into-custom-table/ ? Any code to help me soklve this? Any other suggestion? You sometimes in this forum recommend the plugin "WP Ultimate CSV Importer", but when I asked them, they said: "We do not have support for the Metabox plugin".
In this topic https://support.metabox.io/topic/display-wp-all-import-images-in-image-advanced-field/ you say on October 23, 2021: "We are working to create an integration plugin between MB and WP All Import. Hopefully, it will be released soon." What do you mean by "soon"? This year? I really do hope so!! If you need a beta tester, I will happily be of assistance!
