Meta Box

Thanks a lot Peter, I learned this new function, get_queried_object_id, that will help a lot in the future !

So I made this view working.

There is only one thing with another view. On the same page, I am calling a cloned field.

> 'instrument_de_musique' is a Group
>> 'instrument' and 'niveau' are the two sub-fields (select) of this cloneable group.

Following the same logic, I used the queried object but I don't know how to use it as the clones :

{% set user_id = mb.get_queried_object_id() %}
{% for clone in mb.rwmb_meta( 'instrument_de_musique', {object_type: 'user'}, user_id ) %}
	{{ mb.rwmb_meta( 'instrument', {object_type: 'user'}, clone ) }} - {{ mb.rwmb_meta( 'niveau', {object_type: 'user'}, clone )}}
{% endfor %}

Nothing is displayed. Is rwmb_meta the correct function ? Which arguments should I give ?

Thank you Peter,

yes the users do have the value in the custom fields...

See on this screenshot : https://prnt.sc/G6cJjaeCtguq - You can see the user account backend, the empty one frontend, and the MB view which is called by a shortcode (working, since the text in the view is displayed)

The field is filled in the back office user profile, and also on the edit user profile page.
It doesn't appear frontend...

I asked for help on the facebook group, and I finally found what caused the crash : the callback function.

I deactivated it, and my back-office is back with Metabox AIO.

You can close the ticket !

Thank you for your reply,
I can effectively manage to add the value in the admin area.

My concern is if I can access this values when I set a Custom Field in a Custom Post Type as a "Select" > in the options I don't want to enter the values manually, but access to the options set by the client in the admin area.

Is that possible, do you have any documentation on this subject ?
Thanks

Thank you for your reply, here are the differents things :

php code for setting page :

<?php
add_filter( 'mb_settings_pages', 'your_prefix_function_name' );

function your_prefix_function_name( $settings_pages ) {
    $settings_pages[] = [
        'menu_title' => __( 'Infos Maman Blues', 'your-text-domain' ),
        'position'   => 2,
        'capability' => 'edit_posts',
        'icon_url'   => 'dashicons-admin-generic',
    ];

    return $settings_pages;
}

Code for custom fields

<?php
add_filter( 'rwmb_meta_boxes', 'your_prefix_function_name' );

function your_prefix_function_name( $meta_boxes ) {
    $prefix = '';

    $meta_boxes[] = [
        'title'          => __( 'Adresse postale', 'your-text-domain' ),
        'id'             => 'informations-de-contact',
        'settings_pages' => ['param-maman-blues'],
        'fields'         => [
            [
                'name' => __( 'Nom du contact', 'your-text-domain' ),
                'id'   => $prefix . 'nom_du_contact',
                'type' => 'text',
            ],
            [
                'name' => __( 'Rue', 'your-text-domain' ),
                'id'   => $prefix . 'adresse_postale',
                'type' => 'text',
            ],
            [
                'name' => __( 'Code postal / Ville', 'your-text-domain' ),
                'id'   => $prefix . 'code_postal_ville',
                'type' => 'text',
            ],
        ],
    ];

    return $meta_boxes;
}

The MB Views Code :

<div>
    <b>Nom du site : {{ site.title }}</b><br>
    {{ post.title }}<br>
    {% set group = attribute( site, 'param-maman-blues' ) %}
{{ group.nom_du_contact }}
    {% set group = attribute( site, 'param-maman-blues' ) %}
<img src="{{ group.logo_site.medium.url }}" width="{{ group.logo_site.medium.width }}" height="{{ group.logo_site.medium.height }}" alt="{{ group.logo_site.medium.alt }}">
    
</div>
