Woocommerce可变产品下拉列表

Question

我正在尝试为我的woocommerce商店实施数量下拉,我发现下面的代码启用单个产品,但我不能让它适用于有变化的产品.

<?php
// Place the following code in your theme's functions.php file
// override the quantity input with a dropdown
// Note that you still have to invoke this function like this:
/*
$product_quantity = woocommerce_quantity_input( array(
  'input_name'  => "cart[{$cart_item_key}][qty]",
  'input_value' => $cart_item['quantity'],
  'max_value'   => $_product->backorders_allowed() ? '' : $_product->get_stock_quantity(),
  'min_value'   => '0'
), $_product, false );
*/
function woocommerce_quantity_input($data) {
    global $product;
  $defaults = array(
    'input_name'    => $data['input_name'],
    'input_value'   => $data['input_value'],
    'max_value'   => apply_filters( 'woocommerce_quantity_input_max', '', $product ),
    'min_value'   => apply_filters( 'woocommerce_quantity_input_min', '', $product ),
    'step'    => apply_filters( 'woocommerce_quantity_input_step', '1', $product ),
    'style'   => apply_filters( 'woocommerce_quantity_style', 'float:left; margin-right:10px;', $product )
  );
  if ( ! empty( $defaults['min_value'] ) )
    $min = $defaults['min_value'];
  else $min = 1;
  if ( ! empty( $defaults['max_value'] ) )
    $max = $defaults['max_value'];
  else $max = 20;
  if ( ! empty( $defaults['step'] ) )
    $step = $defaults['step'];
  else $step = 1;
  $options = '';
  for ( $count = $min; $count <= $max; $count = $count+$step ) {
    $selected = $count === $defaults['input_value'] ? ' selected' : '';
    $options .= '<option value="' . $count . '"'.$selected.'>' . $count . '</option>';
  }
  echo '<div class="quantity_select" style="' . $defaults['style'] . '"><select name="' . esc_attr( $defaults['input_name'] ) . '" title="' . _x( 'Qty', 'Product quantity input tooltip', 'woocommerce' ) . '" class="qty">' . $options . '</select></div>';
}
?>

我追求的结果如下图所示

这可能与woocommerce？

事实证明，最好的方法是使用分组产品
