推荐答案

对于简单产品，使用 woocommerce_before_add_to_cart_button 操作将您的产品'_pd_number'自定义字段添加到购物车之前的简单产品页面中用这种方式钩住:

For simple products your product '_pd_number' custom field in simple product pages before add-to-cart, using woocommerce_before_add_to_cart_button action hook this way:

add_action( 'woocommerce_before_add_to_cart_button', 'add_cf_before_addtocart_in_single_products', 1, 0 );
function add_cf_before_addtocart_in_single_products()
{
     global $product;

     $pd_number = get_post_meta( $product->get_id(), '_pd_number', true );
     if( !empty( $pd_number ) )
        echo '<div class="pd-number">PD # '. $pd_number .'</div><br>';

}

代码会出现在您活动的子主题(或主题)的function.php文件或任何插件文件中.

此代码已在WooCommerce 3+及更高版本上进行了测试.

This code is tested on WooCommerce version 3+ and works.

您还可以通过以下方式使用 woocommerce_cart_item_name 过滤器挂钩在名称下方的购物车项目中输出您的产品自定义字段:

You can also output your product custom field in the cart items below the name, using woocommerce_cart_item_name filter hook this way:

// Displaying the product custom field in the Cart items
add_filter( 'woocommerce_cart_item_name', 'add_cf_after_cart_item_name', 10, 3 );
function add_cf_after_cart_item_name( $name_html, $cart_item, $cart_item_key )
{
    $product_id = $cart_item['product_id'];
    if( $cart_item['variation_id'] > 0 )
        $product_id = $cart_item['variation_id'];

     $pd_number = get_post_meta( $product_id, '_pd_number', true );;
     if( !empty( $pd_number ) )
        $name_html .= '<br><span class="pd-number">PD # '.$pd_number .'</span>';

     return $name_html;
}

这是我从他那里使用的代码，它在注释中提供了仅用于测试的链接:

Here the code I have use from he provided link in comments just for testing:

// Display Product settings Fields
add_action( 'woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields' );
function woo_add_custom_general_fields() {
    woocommerce_wp_text_input( array(
        'id'          => '_pd_number',
        'label'       => __( 'PD Number', 'woocommerce' ),
        'placeholder' => 'PD# XXXXXX',
        'desc_tip'    => 'true',
        'description' => __( 'Enter the PD Number of Product', 'woocommerce' )
    ));
}

// Save Product settings Fields
add_action( 'woocommerce_process_product_meta', 'woo_add_custom_general_fields_save' );
function woo_add_custom_general_fields_save( $post_id ){
    $pd_number = $_POST['_pd_number'];
    if( !empty( $pd_number ) )
        update_post_meta( $post_id, '_pd_number', esc_attr( $pd_number ) );
}
