基于WooCommerce中的自定义字段值的电子邮件收件人

Question

我已将自定义字段添加到我的Woocommerce商店的结帐页面。该字段是“餐馆位置”。在客户下订单时，我的目标是使用“餐馆位置”字段确定将订单确认发送至哪个电子邮件。

下面是我如何定义自定义字段。

/////// Hook custom field in /////// 

add_filter('woocommerce_checkout_fields', 'custom_checkout_fields'); 

function custom_checkout_fields($fields) { 

$fields['order']['restaurant_location'] = array(
'label'  => __('Food options', 'woocommerce'), 
'placeholder' => _x('', 'placeholder', 'woocommerce'), 
'required' => true, 
'clear'  => false, 
'type'  => 'select', 
'options'  => array(
    'no' => __('New Orleans', 'woocommerce'), 
    'br' => __('Baton Rouge', 'woocommerce') 
    ) 
); 

return $fields; 

} 

这是我对电子邮件过滤器的尝试。

add_filter('woocommerce_email_recipient_new_order', 'gon_conditional_email_recipient', 10, 2); 

function gon_conditional_email_recipient($recipient, $order) { 

$gon_order_data = $order->get_data(); 
$gon_restaurant_location = $gon_order_data['order']['restaurant_location']; 

if ( $gon_restaurant_location == 'New Orleans') { 
    $recipient = '[email protected]'; 
    return $recipient; 
} 
else if ( $gon_restaurant_location == 'Baton Rouge') { 
    $recipient = '[email protected]'; 
    return $recipient; 
} 

return $recipient; 


} 

电子邮件过滤器工作，即我可以得到一个电子邮件要不要去的地址，但我似乎不能在“$gon_restaurant_location”变量来拉正确。有任何想法吗？

感谢，

您的自定义字段值不保存在数据库中，所以这就是为什么不工作。试试这个完整的解决方案，而不是：

// Add the custom checkout field 
add_filter('woocommerce_after_order_notes', 'restaurant_location_checkout_field'); 
function restaurant_location_checkout_field($checkout) { 

    woocommerce_form_field('restaurant_location', array(
     'type'  => 'select', 
     'class'  => array('my-field-class form-row-wide'), 
     'label'  => __('Food options', 'woocommerce'), 
     'required' => true, 
     'options'  => array(
      '' => __('Please select an option', 'woocommerce'), 
      'New Orleans' => __('New Orleans', 'woocommerce'), 
      'Baton Rouge' => __('Baton Rouge', 'woocommerce') 
     ) 
    ), $checkout->get_value('restaurant_location')); 
} 

// Process the checkout (checking) 
add_action('woocommerce_checkout_process', 'restaurant_location_field_process'); 
function restaurant_location_field_process() { 
    // Check if set, if its not set add an error. 
    if (! $_POST['restaurant_location']) 
     wc_add_notice(__('Please select a food option .'), 'error'); 
} 

// Update the order meta with field value 
add_action('woocommerce_checkout_update_order_meta', 'restaurant_location_field_update_order_meta'); 
function restaurant_location_field_update_order_meta($order_id) { 
    if (! empty($_POST['restaurant_location'])) { 
     update_post_meta($order_id, '_restaurant_location', sanitize_text_field($_POST['restaurant_location'])); 
    } 
} 

// Display field value on the order edit page 
add_action('woocommerce_admin_order_data_after_billing_address', 'my_custom_checkout_field_display_admin_order_meta', 10, 1); 
function my_custom_checkout_field_display_admin_order_meta($order){ 
    echo '<p><strong>'.__('Food options', 'woocommerce').':</strong> ' . get_post_meta($order->get_id(), '_restaurant_location', true) . '</p>'; 
} 

// Conditional Email recipient filter based on restaurant location 
add_filter('woocommerce_email_recipient_new_order', 'conditional_email_recipient', 10, 2); 
function conditional_email_recipient($recipient, $order) { 

    $location = get_post_meta($order->get_id(), '_restaurant_location', true); 
    $recipient = $location == 'New Orleans' ? ',[email protected]' : ',[email protected]'; 
    return $recipient; 
} 

代码放在您的活动子主题（或主题）的function.php文件或也以任何插件文件。
