Hi Long,
I'm trying to display the field label "not value" for my select advanced field choices.

But when I add rwmb_the_value it displays twice? See my pastebin and screenshot. What am I doing wrong / displaying twice?

Thanks in advance!

Hi Brian,

To display the field label, you can use the function rwmb_get_field_settings(). Please follow this documentation https://docs.metabox.io/rwmb-get-field-settings/
and this article https://metabox.io/get-field-settings/.

Hi Long,
Thanks for the reply and pointing me to rwmb_get_field_settings()

I'm getting close but still have a few errors. Is this the correct approach for displaying the labels instead of the value in a select advanced dropdown field?


// Return Select Advanced field labels
    $field = rwmb_get_field_settings('dgp_holiday_availability');
    $options = $field['options'];
    
    // Get all labels
    $values = rwmb_meta('dgp_holiday_availability');
    $labels = array_map( function( $value ) use ( $options ) {
        return $options[$value];
    }, $values );
    
    // Output labels
     if ( $values = rwmb_meta( 'dgp_holiday_availability' ) ) {
     foreach ( $labels as $label ) {
        $new_content .= '<li><span class="holiday-details-label">Availability:</span>' .esc_html( $label ) . '</li>';
        }
    }

Hi,

Please try again with this code

// Return Select Advanced field labels
$field = rwmb_get_field_settings( 'dgp_holiday_availability' );
$options = $field['options'];
    
// Output labels
foreach ($options as $key => $value) {
    echo $value . '<br>';
}
