Meta Box

Thank you. I somehow missed that entirely and that works splendidly!

Now everything works as I expected it to work. Thank you Anh for the support. Appreciate it! There's a bug though, not related to this but something I discovered while trying the fixes regarding this thread.

If you have an image module, upload an image, click the little 'pen' to edit the selected image and select 'delete permanently' the JS will throw an exception and the media.window or whatnot will bug out a bit and won't actually remove the image from the selection although it has been removed from the media library.

Just a smaller annoyance but still, worth mentioning.

Sorry to say, it still doesn't work as expected. The field is hidden now, and visible as it should be. But it still *forgets* when you hit clone.

This is still the code used to test with:

$prefix = '_something_';

$meta_boxes[] = array(
    'title'      => 'Box settings',
    'post_types' => 'page',
    'fields'     => array(
        array(
            'id'          	=> $prefix . 'test',
            'name'        	=> 'Image or video boxes',
            'type'        	=> 'group',
            'clone'       	=> true,
            'sort_clone'  	=> true,
            'collapsible' 	=> true,
            'default_state'	=> 'collapsed',
            'group_title' 	=> 'Box #{#}',
            'save_state' 	=> true,

            'fields' 		=> array(
				array(
				    'name'    			=> 'Image or video?',
				    'id'      			=> $prefix . 'type123',
				    'type'    			=> 'radio',
				    'options' 			=> [ 'img' => 'Image', 'vid' => 'Video', ],
				    'std'			=> 'img',
				    'inline' 			=> false,
				),
				array(
				    'id'               	=> $prefix . 'image',
				    'name'             	=> 'Choose image',
				    'type'             	=> 'image_advanced',
				    'force_delete'     	=> false,
				    'max_file_uploads' 	=> 1,
				    'max_status'       	=> false,
				    'image_size'       	=> 'thumbnail',
				    'visible' 			=> [ $prefix . 'type123', 'img' ],
				),
				array(
				    'id'               	=> $prefix . 'video',
				    'name'             	=> 'Choose video',
				    'type'             	=> 'video',
				    'force_delete'     	=> false,
				    'max_file_uploads' 	=> 1,
				    'max_status'       	=> false,
				    'visible' 			=> [ $prefix . 'type123', 'vid' ],
				),
            ),
        ),
    ),
);

This is a short video showcasing the issue at hand:

As you can see, as soon as I select "+ Add more", the previous is "forgotten".

Hmm can't edit the post. So the code is currently:

$prefix = '_something_';

$meta_boxes[] = array(
    'title'      => 'Box settings',
    'post_types' => 'page',
    'fields'     => array(
        array(
            'id'          	=> $prefix . 'test',
            'name'        	=> 'Image or video boxes',
            'type'        	=> 'group',
            'clone'       	=> true,
            'sort_clone'  	=> true,
            'collapsible' 	=> true,
            'default_state'	=> 'collapsed',
            'group_title' 	=> 'Box #{#}',
            'save_state' 	=> true,

            'fields' 		=> array(
				array(
				    'name'    			=> 'Image or video?',
				    'id'      			=> $prefix . 'type123',
				    'type'    			=> 'radio',
				    'options' 			=> [ 'img' => 'Image', 'vid' => 'Video', ],
				    'std'				=> 'img',
				    'inline' 			=> false,
				),
				array(
				    'id'               	=> $prefix . 'image',
				    'name'             	=> 'Choose image',
				    'type'             	=> 'image_advanced',
				    'force_delete'     	=> false,
				    'max_file_uploads' 	=> 1,
				    'max_status'       	=> false,
				    'image_size'       	=> 'thumbnail',
				    'visible' 			=> [ $prefix . 'type123', 'img' ], // <-- not working
				),
				array(
				    'id'               	=> $prefix . 'video',
				    'name'             	=> 'Choose video',
				    'type'             	=> 'video',
				    'force_delete'     	=> false,
				    'max_file_uploads' 	=> 1,
				    'max_status'       	=> false,
				    'visible' 			=> [ $prefix . 'type123', 'vid' ], // <-- not working
				),
            ),
        ),
    ),
);

And the above video applies. As you can see, it does not function as intended. It resets the value when you clone as for radio, it shows image selection by default outside collapse although being in collapsed state by default.. Yeah I can't get this to work.
