将产品自定义字段单选按钮值保存在购物车中并将其显示在购物车页面上

问题描述

限时删除！！

我在主题主题的functions.php上使用以下代码在woocommerce单一产品页面上添加了一些自定义选项：

I have added some custom options on woocommerce single product page using the code below on my theme's functions.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。请帮我做到这一点。
谢谢

Now i want to display the selected option value on cart page. Please help me to do this.Thanks

推荐答案

以下是将产品自定义字段存储在购物车对象中并在购物车和结帐中显示的完整代码页面：

Here is the complete code to Store product custom field in cart object and display that in Cart and Checkout pages:

// 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;
}
