Meta Box

Hello,

Yes, I think it is possible. You can read more on the documentation https://fluentforms.com/connect-meta-box-wordpress-with-fluent-forms/

The Fluent Forms team maintains the integration with Meta Box so I recommend contacting Fluent Forms support to get further assistance.

Hello,

I've replied to your ticket a few days ago about the incorrect account. Can you please recheck that?

Hello,

Please check this code for example:

function my_unique_filename_callback( $dir, $name, $ext ) {
    $name = substr(md5($name), 0, 10);
    return $name . $ext;
}

add_filter( 'rwmb_meta_boxes', 'ajf_randomize_uploaded_filename' );
function ajf_randomize_uploaded_filename( $meta_boxes ) {

    $meta_boxes[] = [
        'title'  => __( 'My User Meta', 'your-text-domain' ),
        'id'     => 'my-user-meta',
        'type'   => 'user',
        'fields' => [
            [
                'name'                     => __( 'File', 'resume' ),
                'id'                       => 'file',
                'type'                     => 'file',
                'upload_dir'               => WP_CONTENT_DIR . '/uploads/resumes/',
                'unique_filename_callback' => 'my_unique_filename_callback',
            ],
        ],
    ];
    return $meta_boxes;
}

If you don't know how to use the code to register custom fields and meta box, please read more on the documentation https://docs.metabox.io/creating-fields-with-code/

Hello,

Each meta box relationship has the ID with the following format relatioshipID_relationships_from or relatioshipID_relationships_to. You can use conditional logic outside of meta box with that ID to show/hide the relationship meta box. Please read more on the documentation https://docs.metabox.io/extensions/meta-box-conditional-logic/#using-outside-meta-boxes

Hello,

Please export the field group to the JSON file and share it with me or share the PHP code generated, I will check the issue on my local site.

Hello,

Thank you for your feedback.

Currently, MB relationship select box only supports selecting one object per selection. You can add more objects and it also supports searching for objects with the default field type select_advanced.

Hello,

Because the helper function rwmb_meta() runs after the filter hook rwmb_meta_boxes so you can use the function get_option() to get settings page value inside the function callback.

Hello,

Can you please share a screenshot when you edit the taxonomy > General tab? Is the "Object_type1" taxonomy slug?
