I've created a custom field plugin type "file" and am using it as custom field on articles so users can upload a file (the "media" type file does not suit my needs).
It looks and works OK while editing the article, but how do I manage to handle the upload itself?
In other words, when I save the article, jform[com_fields][my-file-field-name] is included on the submitted form data, but I do not know where to place the actual code to handle the uploaded file.
