Meta Box

Hi Long

Thanks again but just FYI when I am using the code above, when I try to retrieve the value with

$video_options_list = rwmb_meta('settings_test_video_list', ['object_type' => 'setting'], 'settings_test' );

then nothing is returned. Is that the correct way to get the field? I also cannot get the single field 'settings_test_single_id' using rwmb_meta().

No worries though because 'get_option()' works fine -

$settings_test = get_option('settings_test');
$single = $settings_test['settings_test_single_id'];
$video_options_list = $settings_test['settings_test_video_list'];

All expected vallues/arrays returned fine

Hi Long

Thanks for your reply. The problem is I am trying to create a pseudo index field I can use in the select vaule on the Page meta. So on the settings page with the list of videos I have added a 'video id' field which I need to automatically increment to create a unique Id for each row in the group. For a single, non cloned, field I can use the Rwmb_{field_id}_value filter to set the index value if it is empty or leave alone if it is already set. But for a cloneable group field that filter does not work.

Here is my testing settings page definition with test code filters to test the 'value' filter.

// Register meta boxes and fields for settings page
add_filter( 'rwmb_meta_boxes', function ( $meta_boxes ) {
    $prefix = "settings_test_";
    $meta_boxes[] = array(
        'id'             => $prefix .'general',
        'title'          => 'General',
        'settings_pages' => 'settings_test',
        'tab'            => 'general',
        'fields' => array(
            array(
                'type' => 'custom_html',
                'std'  => 'General theme settings will be added here',
            ),
            array(
                'name' => 'Single Id',
                'id' => $prefix . 'single_id',
                'type' => 'number',
                'std' => 0,
            ),
        ),
    );
    $meta_boxes[] = array(
        'id'             => $prefix . 'videos',
        'title'          => 'Highlight Video Options',
        'settings_pages' => 'settings_test',
        'tab'            => 'highlights',
        'fields' => array(
            array(
                'type' => 'custom_html',
                'std'  => 'Here is the list of  highlight videos. Add videos here to be included in the highlight video list.',
            ),

            array(
                'id'     => $prefix . 'video_list',
                // Group field
                'name' => "Videos",
                'type'   => 'group',
                // Clone whole group?
                'clone'  => true,
                // Drag and drop clones to reorder them?
                'sort_clone' => true,
                'collapsible' => true,
                'group_title' => array( 'field' => $prefix .'video_name' ), // ID of the subfield
                'save_state' => true,
                // Sub-fields
                'fields' => array(
                    array(
                        'name' => 'Video Name',
                        'id' => $prefix . 'video_name',
                        'description' => 'Name for dropdown list',
                        'type' => 'text'
                    ),
                    array(
                        'name' => 'Video URL',
                        'id' => $prefix . 'video_url',
                        'type' => 'url'

                    ),
                    array(
                        'name' => 'Id',
                        'id' => $prefix . 'video_id',
                        'type' => 'number',
                        'std' => 0,
                    )
                ),
            ),
        ),
    );
    $meta_boxes[] = array(
        'id'             => 'info',
        'title'          => 'Theme Info',
        'settings_pages' => 'settings_test',
        'tab'            => 'faq',
        'fields'         => array(
            array(
                'type' => 'custom_html',
                'std'  => 'Having questions? Check out our documentation',
            ),
        ),
    );
    return $meta_boxes;
} );

add_filter('rwmb_settings_test_video_id_value', 'settings_test_autoinc_value', 10, 3 );
function settings_test_autoinc_value($new, $field, $old) {
    global  $shsLog;
    $shsLog->trace("Entry - New - $new - old - $old");
    if (empty($new)) {
        $new = 4222;
    }else {
        $new = 21223;
    }
    return $new;
}

add_filter('rwmb_settings_test_single_id_value', 'settings_test_single_value', 10, 3 );
function settings_test_single_value($new, $field, $old) {
    global  $shsLog;
    $shsLog->trace("Entry - New - $new - old - $old");
    if (empty($new)) {
        $new = 4222;
    }else {
        $new = 21223;
    }
    return $new;
}

In testing the filter 'settings_test_single_value()' is called as expected. However the filter for the cloned id field filter 'settings_test_autoinc_value()' is never called. I have tried creating a custom field type but the ::value() function is never called if the field is cloneable.

Is there anyway round this?

Thanks Anh Tran, should have realised that!
