Registering File Types
Sometimes, a project may need new file type(s) to be uploadable in the File Upload field. You may register additional file types can be added using a WordPress plugin or hook:
- Use a plugin from the WordPress plugin repository that allows you to register new file types in WordPress.
- Register additional file types using the upload_mimes WordPress hook using WPCodeBox, another code snippets plugin, or a custom plugin.
After you register a new file type in WordPress, you may then select that file type in the Oxygen File Upload field under the Allowed File Types control or leave that control blank to allow all file types to be uploaded.
