我在WooCommerce的后端成功添加了产品变体的自定义字段,并且能够显示其价值。我希望在订单和电子邮件中包含此值。
//Display Fields in admin on product edit screen
add_action( 'woocommerce_product_after_variable_attributes', 'woo_variable_fields', 10, 3 );
//Save variation fields values
add_action( 'woocommerce_save_product_variation', 'save_variation_fields', 10, 2 );
// Create new fields for variations
function woo_variable_fields( $loop, $variation_data, $variation ) {
echo '<div class="variation-custom-fields">';
// Text Field
woocommerce_wp_text_input(
array(
'id' => '_text_field['. $loop .']',
'label' => __( 'additional fees (e.g. monthly fee)', 'woocommerce' ),
'placeholder' => '',
//'desc_tip' => true,
'wrapper_class' => 'form-row form-row-first',
//'description' => __( 'Enter the custom value here.', 'woocommerce' ),
'value' => get_post_meta($variation->ID, '_text_field', true)
)
);
echo "</div>";
}
/** Save new fields for variations */
function save_variation_fields( $variation_id, $i) {
// Text Field
$text_field = stripslashes( $_POST['_text_field'][$i] );
update_post_meta( $variation_id, '_text_field', esc_attr( $text_field ) );
}
// Custom Product Variation
add_filter( 'woocommerce_available_variation', 'custom_load_variation_settings_products_fields' );
function custom_load_variation_settings_products_fields( $variations ) {
$variations['variation_custom_field'] = get_post_meta( $variations[ 'variation_id' ], '_text_field', true );
return $variations;
}
我使用以下内容在购物车中显示自定义字段的值。
add_filter( 'woocommerce_get_item_data', 'display_custom_field_as_item_data', 20, 2 );
function display_custom_field_as_item_data( $cart_data, $cart_item ) {
if( $value = get_post_meta( $cart_item['data']->get_id(), '_text_field', true ) ){
$cart_data[] = array(
'name' => __( 'Additional Monthly Fee', 'woocommerce' ),
'value' => sanitize_text_field( $value )
);
}
return $cart_data;
}
此外,我现在以低于产品价格/购物车/结帐模板中每件商品总价的价格显示以下
echo get_post_meta( $_product->get_id(), '_text_field', true );
如何在订单和电子邮件中显示此字段的值?

已更新:要在订单页面和电子邮件通知中显示,请尝试以下附加功能(我已在woocommerce_get_item_data
挂钩功能中进行了一些更改,因此您需要更换它与以下一个):
// Save custom field value in cart item
add_filter( 'woocommerce_add_cart_item_data', 'save_custom_field_in_cart_object', 30, 3 );
function save_custom_field_in_cart_object( $cart_item_data, $product_id, $variation_id ) {
// Get the correct Id to be used
$the_id = $variation_id > 0 ? $variation_id : $product_id;
if( $value = get_post_meta( $the_id, '_text_field', true ) )
$cart_item_data['custom_data'] = sanitize_text_field( $value );
return $cart_item_data;
}
// Display on cart and checkout pages
add_filter( 'woocommerce_get_item_data', 'display_custom_field_as_item_data', 20, 2 );
function display_custom_field_as_item_data( $cart_data, $cart_item ) {
if( isset( $cart_item['custom_data'] ) ){
$cart_data[] = array(
'name' => __( 'Additional Monthly Fee', 'woocommerce' ),
'value' => $cart_item['custom_data']
);
}
return $cart_data;
}
// Save custom field value in order items meta data
add_action( 'woocommerce_add_order_item_meta', 'add_custom_field_to_order_item_meta', 20, 3 );
function add_custom_field_to_order_item_meta( $item_id, $values, $cart_item_key ) {
if( isset( $values['custom_data'] ) )
wc_add_order_item_meta( $item_id, __( 'Additional Monthly Fee', 'woocommerce' ), $values['custom_data'] );
}
代码进入活动子主题(或主题)的function.php文件。经过测试和工作。
它将在所有订单页面和电子邮件通知中显示自定义字段标签和值。
