Attaching media to custom posts without editor

At the top of wp-admin/edit-form-advanced.php I see the following code that seems related to the media uploader: if ( post_type_supports($post_type, ‘editor’) || post_type_supports($post_type, ‘thumbnail’) ) { add_thickbox(); wp_enqueue_script(‘media-upload’); } You’ll need to add these yourself. add_thickbox() enqueues both a script and a style, so make sure you hook into print_styles, as print_scripts will be too … Read more
