IPTC/EXIF mapping in custom plugin

Thanks for your encouraging words and for your question.

The wp_handle_upload() function does only part of the job, “sanitizing file names, checking extensions for mime type, and moving the file to the appropriate directory within the uploads directory.” The WordPress Codex function reference suggests that it “… may be used with wp insert attachment(). ” The function reference for wp insert attachment() suggests “To perform the entire attachment upload and insertion process at once, you will want to use media_handle_upload() instead in most cases.“

MLA uses the hooks provided by wp insert attachment() and media_handle_upload() to map metadata automatically as items are uploaded and added to the Media Library. If your administration panel can use those functions instead of or in addition to wp_handle_upload() you shouldn’t have a problem. Would that work in your application?

If not, I may be able to suggest some code that will run the MLA mapping rules as a part of your upload process. It would be very helpful to see more of the code around your wp_handle_upload() calls to make sure I am on the right track.

Any additional information you can provide would be most helpful.
