我使用的是“ Additional field on checkout for specific payment gateway in Woocommerce” 答案代码,该代码在结帐页面中为特定的支付网关显示了另一个下拉字段。
如何保存和显示订单和电子邮件通知上的选项?
答案 0 :(得分:0)
add_action('woocommerce_checkout_update_order_meta','custom_checkout_field_update_order_meta');
函数custom_checkout_field_update_order_meta($ order_id)
{
if(!empty($ _ POST ['field_slug'])){
update_post_meta($ order_id,'Some key',sanitize_text_field($ _ POST ['field_slug']));
}
} 要在订单详细信息或电子邮件模板页面中获取此值,可以使用get_post_meta($ order_id,'Some key',false);

的延续
以下是完整的方法:
代码:
// BACS payement gateway description: Append custom select field
add_filter( 'woocommerce_gateway_description', 'gateway_bacs_custom_fields', 20, 2 );
function gateway_bacs_custom_fields( $description, $payment_id ){
//
if( 'bacs' === $payment_id ){
ob_start(); // Start buffering
echo '<div class="bacs-options" style="padding:10px 0;">';
woocommerce_form_field( 'bacs_option', array(
'type' => 'select',
'label' => __("Fill in this field", "woocommerce"),
'class' => array('form-row-wide'),
'required' => true,
'options' => array(
'' => __("Select something", "woocommerce"),
'Option 1' => __("Choice one", "woocommerce"),
'Option 2' => __("Choice two", "woocommerce"),
),
), '');
echo '<div>';
$description .= ob_get_clean(); // Append buffered content
}
return $description;
}
// Checkout custom field validation
add_action('woocommerce_checkout_process', 'bacs_option_validation' );
function bacs_option_validation() {
if ( isset($_POST['payment_method']) && $_POST['payment_method'] === 'bacs'
&& isset($_POST['bacs_option']) && empty($_POST['bacs_option']) ) {
wc_add_notice( __( 'Please Select an option for "Direct Bank Transfer" payment, please.' ), 'error' );
}
}
// Checkout custom field save to order meta
add_action('woocommerce_checkout_create_order', 'save_bacs_option_order_meta', 10, 2 );
function save_bacs_option_order_meta( $order, $data ) {
if ( isset($_POST['bacs_option']) && ! empty($_POST['bacs_option']) ) {
$order->update_meta_data( '_bacs_option' , esc_attr($_POST['bacs_option']) );
}
}
// Display custom field on order totals lines everywhere
add_action('woocommerce_get_order_item_totals', 'display_bacs_option_on_order_totals', 10, 3 );
function display_bacs_option_on_order_totals( $total_rows, $order, $tax_display ) {
if ( $order->get_payment_method() === 'bacs' && $bacs_option = $order->get_meta('_bacs_option') ) {
$sorted_total_rows = [];
foreach ( $total_rows as $key_row => $total_row ) {
$sorted_total_rows[$key_row] = $total_row;
if( $key_row === 'payment_method' ) {
$sorted_total_rows['bacs_option'] = [
'label' => __( "Bank wire option", "woocommerce"),
'value' => esc_html( $bacs_option ),
];
}
}
$total_rows = $sorted_total_rows;
}
return $total_rows;
}
// Display custom field in Admin orders, below billing address block
add_action( 'woocommerce_admin_order_data_after_billing_address', 'display_bacs_option_near_admin_order_billing_address', 10, 1 );
function display_bacs_option_near_admin_order_billing_address( $order ){
if( $bacs_option = $order->get_meta('_bacs_option') ) {
echo '<div class="bacs-option">
<p><strong>'.__('BACS option').':</strong> ' . $bacs_option . '</p>
</div>';
}
}
代码进入活动子主题(或活动主题)的functions.php文件中。经过测试并可以正常工作。

在“收到订单”页面上(在“订单”视图和电子邮件通知上):
