$product = get_fields( $post_id );
$json_ld = [
    '@context' => 'https://schema.org',
    '@type'    => 'Product',
    'name'     => get_the_title( $post_id ),
    'offers'   => [

$objects = get_field_objects( 42 );

// Render all fields automatically based on type
foreach ( $objects as $name => $field ) {
    if ( $field['type'] === 'image' && $field['value'] ) {
        echo '<figure>';
        echo '<img src="' . esc_url( $field['value']['url'] ) . '" alt="' . esc_attr( $field['value']['alt'] ) . '">';

        echo esc_html( $field['value'] ) . '</p>';
    }
}

// Export all field definitions for documentation
$all_objects = get_field_objects( 42 );
$schema = [];
foreach ( $all_objects as $name => $obj ) {
    $schema[] = [
        'name'     => $obj['name'],
        'type'     => $obj['type'],
        'label'    => $obj['label'],
