Meta Box

Hi Flikweert, thanks for reporting it. I will check it soon later today.

Sorry, the validation hasn't worked for media fields for now :(. We use complicated JS to handle upload/insert files and generate the HTML dynamically. That makes the validation JS not work 🙁

I think I answered this question in this topic. Please try.

I think it would be better if you have default values for your settings, and then you don't need to check with if:

$default = array();
$settings = get_option( 'setting_id' );
$settings = wp_parse_args( $settings, $default );

// Then
echo $settings[$field_id];

Great that you made it!

Hi,

I think you can use a trick to find the correct meta box for your settings page and add/edit fields/tabs for it.

The trick is using a key for meta boxes, like this:

$meta_boxes['prefix_settings_page_id'] = array();

And in your extension:

$meta_boxes['prefix_settings_page_id']['tabs'][] = array();
$meta_boxes['prefix_settings_page_id']['fields'][] = array();

Just make sure the extension hooks into the rwmb_meta_boxes after the main plugin.

This technique is covered partly in this documentation https://metabox.io/docs/edit-remove-meta-boxes/.

Unfortunately no :(. I couldn't make it run on my Windows. I think XAMPP Lite included in DS conflicts with XAMPP somehow.

I see. AFAIK, the select2 library doesn't have options to drag and drop selected items :(. There are some questions about the same issue on Github and StackOverflow. This is the limit of the library we use for select_advanced field.
