在Woocommerce的订单电子邮件表单中，我无法从select下拉列表中显示自定义字段数据。数据显示在管理页面顺序中，而不是电子邮件？
add_action( \'woocommerce_after_order_notes\', \'my_custom_checkout_field\' );
function my_custom_checkout_field( $checkout ) {
echo \'<div class="clear"></div><br/>\';
echo \'<div id="my_custom_checkout_field"><h3 style="margin:0 0 0.3em;">Payment Options</h3>\';
echo \'<p style="margin:0 0 0.8em;clear:left;">Please select your preferred payment method below:</p>\';
global $current_user;
get_currentuserinfo();
if ( user_can( $current_user, "wholesale_buyer" ) ){
echo \'<div class="pTrade" style="clear:left;">\';
woocommerce_form_field( \'pTrade\', array(
\'type\' => \'select\',
\'class\' => false,
\'label\' => __(\'\', \'woocommerce\'),
\'required\' => false,
\'options\' => array(
\'\' => __(\'Select\', \'woocommerce\' ),
\'paypal\' => __(\'PayPal invoice\', \'woocommerce\' ),
\'bank\' => __(\'Bank Transfer\', \'woocommerce\' ),
\'credit\' => __(\'Credit Account\', \'woocommerce\' ),
\'cash\' => __(\'Pickup & Pay\', \'woocommerce\' )
)
), $checked );
echo \'</div>\';
} else {
echo \'<div class="pRetail" style="clear:left;">\';
woocommerce_form_field( \'pRetail\', array(
\'type\' => \'select\',
\'class\' => false,
\'label\' => __(\'\', \'woocommerce\'),
\'required\' => false,
\'options\' => array(
\'\' => __(\'Select\', \'woocommerce\' ),
\'paypal\' => __(\'PayPal invoice\', \'woocommerce\' ),
\'bank\' => __(\'Bank Transfer\', \'woocommerce\' ),
\'cash\' => __(\'Pickup & Pay\', \'woocommerce\' )
)
), $checked );
echo \'</div>\';
}
echo \'<p style="margin:0 0 0.8em;clear:left;color:red;"><strong>Note:</strong> Selecting to pay through "PayPal invoice" adds 5% to your order total. <br/> You will recieve an email from PayPal requesting the amount below + 5%. </p>\';
echo \'</div>\';
echo \'<div class="clear"></div>\';
}
/** Update the order meta with field value WORKING ****************/
add_action(\'woocommerce_checkout_update_order_meta\', \'my_custom_checkout_field_update_order_meta\');

$keys[\'Trade pay by:\'] = \'pTrade\';
$keys[\'Retail pay by:\'] = \'pRetail\';
return $keys;
}

如果您提供的代码是您用来实现所需的唯一代码，那么这就是不完整的代码。下面是代码的测试版本，运行良好。我希望这有助于：
/* Add the field to the checkout */
add_action(\'woocommerce_after_order_notes\', \'my_custom_checkout_field\');
function my_custom_checkout_field( $checkout ) {
echo \'<div id="my_custom_checkout_field"><h3>\'.__(\'My Field\').\'</h3>\';
woocommerce_form_field( \'p_trade\', array(
\'type\' => \'select\',
\'class\' => array(\'p-trade orm-row-wide\'),
\'label\' => __(\'Trade Details\'),
\'placeholder\' => __(\'Enter a number\'),
\'clear\' => true,
\'options\' => array( \'trade-1\' => \'Trade One\', \'trade-2\' => \'Trade Two\', \'trade-3\' => \'Trade Three\', \'trade-4\' => \'Trade Four\' )
), $checkout->get_value( \'p_trade\' ));
woocommerce_form_field( \'p_retail\', array(
\'type\' => \'select\',
\'class\' => array(\'p-retail orm-row-wide\'),
\'label\' => __(\'Retail Details\'),
\'placeholder\' => __(\'Enter a number\'),
\'clear\' => true,
\'options\' => array(\'retail-1\' => \'Retail One\', \'retail-2\' => \'Retail Two\', \'retail-3\' => \'Retail Three\', \'retail-4\' => \'Retail Four\')
), $checkout->get_value( \'p_retail\' ));
echo \'</div>\';
}
/* Update the order meta with field value */
add_action(\'woocommerce_checkout_update_order_meta\', \'my_custom_checkout_field_update_order_meta\');
function my_custom_checkout_field_update_order_meta( $order_id ) {
if ($_POST[\'p_trade\']) update_post_meta( $order_id, \'p_trade\', esc_attr($_POST[\'p_trade\']));
if ($_POST[\'p_retail\']) update_post_meta( $order_id, \'p_retail\', esc_attr($_POST[\'p_retail\']));
}
/* Add the fields to order email */
add_filter( \'woocommerce_email_order_meta_keys\', \'my_custom_checkout_field_order_meta_keys\' );
function my_custom_checkout_field_order_meta_keys( $keys ) {
echo \'<h3>Payment Option:</h3>\';
$keys[\'Trade\'] = \'p_trade\';
$keys[\'Retail\'] = \'p_retail\';
return $keys;
}
