我在 Woocommerce 结帐页面的帐单地址中添加了自定义字段，效果很好。 现在，我想在电子邮件的“帐单地址”框中以及“我的帐户”的订单摘要页面上显示这些字段自定义字段的值。 这是我正在使用的代码，它工作正常，但我唯一缺少的是将字段定位在电子邮件和订单摘要视图中，并使管理页面中的字段可编辑（如 woocomerce 中的其他计费字段） 。 是否有挂钩或方法可以显示“帐单地址”框中这些自定义字段的值？ 我做不到，如果你帮助我，我将非常感激
创建自定义字段
add_filter( 'woocommerce_checkout_fields', 'custom_fields_checkout' );
function custom_fields_checkout( $fields ) {
$fields['billing']['codice_fiscale'] = array(
'label' => 'Codice fiscale',
'type' => 'text',
'required' => true,
'class' => array( 'form-row-last' ),
'priority' => 30,
);
$fields['billing']['partita_iva'] = array(
'label' => 'Partita iva',
'type' => 'text',
'required' => false,
'class' => array( 'form-row-first' ),
'priority' => 31,
);
$fields['billing']['codice_univoco'] = array(
'label' => 'Codice Univoco',
'type' => 'text',
'required' => false,
'class' => array( 'form-row-last' ),
'priority' => 32,
);
return $fields;
}
保存字段
add_action( 'woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta' );
function my_custom_checkout_field_update_order_meta( $order_id ) {
if ( ! empty( $_POST['codice_fiscale'] ) ) {
update_post_meta( $order_id, 'codice_fiscale', sanitize_text_field( $_POST['codice_fiscale'] ) );
}
if ( ! empty( $_POST['partita_iva'] ) ) {
update_post_meta( $order_id, 'partita_iva', sanitize_text_field( $_POST['partita_iva'] ) );
}
if ( ! empty( $_POST['codice_univoco'] ) ) {
update_post_meta( $order_id, 'codice_univoco', sanitize_text_field( $_POST['codice_univoco'] ) );
}
}
显示订单管理页面中的字段
add_action( 'woocommerce_admin_order_data_after_billing_address', 'display_custom_field_on_order_edit_pages', 10, 1 );
function display_custom_field_on_order_edit_pages( $order ){
if($codice_fiscale = get_post_meta( $order->get_id(), 'codice_fiscale', true ));
echo '<p><strong>Codice fiscale: </strong>' . $codice_fiscale . '</p>';
if($partita_iva = get_post_meta( $order->get_id(), 'partita_iva', true ));
echo '<p><strong>Partita iva: </strong>' . $partita_iva .'</p>';
if($codice_univoco = get_post_meta( $order->get_id(), 'codice_univoco', true ));
echo '<p><strong>Codice univoco: </strong>' . $codice_univoco . '</p>';
}
显示电子邮件中的字段
add_action( 'woocommerce_email_after_order_table', 'ts_email_after_order_table', 10, 4 );
function ts_email_after_order_table( $order, $sent_to_admin, $plain_text, $email ) {
if($codice_fiscale = get_post_meta( $order->get_id(), 'codice_fiscale', true ));
echo '<p><strong>Codice fiscale: </strong>' . $codice_fiscale . '</p>';
if($partita_iva = get_post_meta( $order->get_id(), 'partita_iva', true ));
echo '<p><strong>Partita iva: </strong>' . $partita_iva .'</p>';
if($codice_univoco = get_post_meta( $order->get_id(), 'codice_univoco', true ));
echo '<p><strong>Codice univoco: </strong>' . $codice_univoco . '</p>';
}
测试修改后的代码，我哪里错了？
function add_custom_billing_fields( $fields ) {
$fields['billing_codice_fiscale'] = array(
'label' => ( 'Codice fiscale'),
'type' => 'text',
'required' => true,
'class' => array( 'form-row-last' ),
'priority' => 30,
);
$fields['billing_partita_iva'] = array(
'label' => 'Partita iva',
'type' => 'text',
'required' => false,
'class' => array('form-row-wide'),
'priority' => 31,
);
$fields['billing_codice_univoco'] = array(
'label' => 'Codice Univoco',
'type' => 'text',
'required' => false,
'class' => array( 'form-row-wide' ),
'priority' => 32,
);
return $fields;
}
add_filter( 'woocommerce_billing_fields', 'add_custom_billing_fields' );
add_action( 'woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta' );
function my_custom_checkout_field_update_order_meta( $order_id ) {
if ( ! empty( $_POST['billing_codice_fiscale'] ) ) {
update_post_meta( $order_id, 'billing_codice_fiscale', sanitize_text_field( $_POST['billing_codice_fiscale'] ) );
}
if ( ! empty( $_POST['billing_partita_iva'] ) ) {
update_post_meta( $order_id, 'billing_partita_iva', sanitize_text_field( $_POST['billing_partita_iva'] ) );
}
if ( ! empty( $_POST['billing_codice_univoco'] ) ) {
update_post_meta( $order_id, 'billing_codice_univoco', sanitize_text_field( $_POST['billing_codice_univoco'] ) );
}
}
