// hook in add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );  // our hooked in function - $fields passed via filter! function custom_override_checkout_fields( $fields ) {      $fields['billing']['billing_infos'] = array(         'type'      => 'textarea',         'label'     => __('notes de la commande', 'woocommerce'),     'placeholder'   => _x('commentaires concernant votre commande', 'placeholder', 'woocommerce'),     'required'  => false,     'class'     => array('form-row-wide'),     'clear'     => true      );       return $fields; }
