Question

我已经在woocommerce单品页面上添加了一些自定义选项，使用下面的代码在我的主题函数中.php：

     function options_on_single_product(){
     ?>
      <input type="radio" name="option1" checked="checked" value="option1"> option 1 <br />
      <input type="radio" name="option1" value="option2"> option 2
       <?php
      }
       add_action("woocommerce_before_add_to_cart_button", "options_on_single_product");

现在我想在购物车页面上显示所选的选项值。请帮我这样做。感谢

以下是在cart对象中存储产品自定义字段并在Cart和Checkout页面中显示的完整代码：

// Output the Custom field in Product pages
add_action("woocommerce_before_add_to_cart_button", "options_on_single_product", 1);
function options_on_single_product(){
    ?>
        <label for="custom_field">
            <input type="radio" name="custom_field" checked="checked" value="option1"> option 1 <br />
            <input type="radio" name="custom_field" value="option2"> option 2
        </label> <br />
    <?php
}

// Stores the custom field value in Cart object
add_filter( 'woocommerce_add_cart_item_data', 'save_custom_product_field_data', 10, 2 );
function save_custom_product_field_data( $cart_item_data, $product_id ) {
    if( isset( $_REQUEST['custom_field'] ) ) {
        $cart_item_data[ 'custom_field' ] = $_REQUEST['custom_field'];
        // below statement make sure every add to cart action as unique line item
        $cart_item_data['unique_key'] = md5( microtime().rand() );
        WC()->session->set( 'my_order_data', $_REQUEST['custom_field'] );
    }
    return $cart_item_data;
}

// Outuput custom Item value in Cart and Checkout pages
add_filter( 'woocommerce_get_item_data', 'output_custom_product_field_data', 10, 2 );
function output_custom_product_field_data( $cart_data, $cart_item ) {

    if( !empty( $cart_data ) )
        $custom_items = $cart_data;

    if( isset( $cart_item['custom_field'] ) ) {
        $custom_items[] = array(
            'key'       => __('Custom Item', 'woocommerce'),
            'value'     => $cart_item['custom_field'],
            'display'   => $cart_item['custom_field'],
        );
    }
    return $custom_items;
}

代码放在活动子主题（或主题）的function.php文件中，或者放在任何插件文件中。

此代码经过测试并有效。
