I use the plugin happyfiles, and have created some categories like Avatar
Then I have created some custom fields for users included an image field for an avatar images.
So my problem is, when uploading the image through the frontend submission, the images goes to the default media library and is not assigned to any category by happyfiles "happyfiles_category" aka Avatar
I have contacted Thomas from happyfiles and his note was:
A HappyFiles folder is a custom taxonomy term in your database.
You could hook into the upload file event and assign any folder (= term_id) you like to it.
The HappyFiles taxonomy slug for files is: happyfiles_category
So my question is, can this be done by the metabox custom field, ex may be in the advanced / Custom settings.
And if yes how ?
