【问题描述】：

我们使用下面的 function.php 代码在结帐时提供多选字段。我们将其添加到订单页面并将其包含在电子邮件中。

我们如何将它也包含在 ORDERs 概览管理页面中，使其可搜索和排序？

// add select box for platform used at checkout
add_action('woocommerce_after_order_notes', 'wps_add_select_checkout_field');
function wps_add_select_checkout_field( $checkout ) {
    echo '<h3>'.__('').'</h3>';
    woocommerce_form_field( 'platform', array(
        'type'          => 'select',
        'class'         => array( 'wps-drop' ),
        'label'         => __( 'On which platform will you be using it?' ),
        'options'       => array(
            'blank'     => __( '-- Choose an option --', 'wps' ),
            'app1'  => __( 'app1', 'wps' ),
            'app2'  => __( 'app2', 'wps' ),
            'app3'  => __( 'app3', 'wps' )
        )
    ), $checkout->get_value( 'platform' ) );
}

// Process the checkout
 add_action('woocommerce_checkout_process', 'wps_select_checkout_field_process');
 function wps_select_checkout_field_process() {
    global $woocommerce;

    // Check if set, if its not set add an error.
    if ($_POST['platform'] == "blank")
        wc_add_notice( '<strong>Please select your primary trading platform that you will be using with our strategy</strong>', 'error' );
 }


 // Update the order meta with field value
 add_action('woocommerce_checkout_update_order_meta', 'wps_select_checkout_field_update_order_meta');
 function wps_select_checkout_field_update_order_meta( $order_id ) {
     if ($_POST['platform']) update_post_meta( $order_id, 'platform', esc_attr($_POST['platform']));
 }

 // Display field value on the order edition page
add_action( 'woocommerce_admin_order_data_after_billing_address', 'wps_select_checkout_field_display_admin_order_meta', 10, 1 );
function wps_select_checkout_field_display_admin_order_meta($order){
    echo '<p><strong>'.__('Primary Platform').':</strong> ' . get_post_meta( $order->id, 'platform', true ) . '</p>';
}

// Add selection field value to emails
add_filter('woocommerce_email_order_meta_keys', 'wps_select_order_meta_keys');
function wps_select_order_meta_keys( $keys ) {
    $keys['platform:'] = 'platform';
    return $keys;
}

【解决方案1】：

这是在管理员 WooCommerce 订单列表中添加自定义列“平台”并在搜索中添加此自定义字段元键的方法：

// ADDING A CUSTOM COLUMN TITLE TO ADMIN ORDER LIST
add_filter( 'manage_edit-shop_order_columns', 'custom_shop_order_column', 12, 1 );
function custom_shop_order_column($columns)
{
    // Set "Actions" column after the new colum
    $action_column = $columns['order_actions']; // Set the title in a variable
    unset($columns['order_actions']); // remove  "Actions" column


    //add the new column "Platform"
    $columns['order_platform'] = '<span>'.__( 'Platform','woocommerce').'</span>'; // title

    // Set back "Actions" column
    $columns['order_actions'] = $action_column;

    return $columns;
}

// ADDING THE DATA FOR EACH ORDERS BY "Platform" COLUMN
add_action( 'manage_shop_order_posts_custom_column' , 'custom_order_list_column_content', 10, 2 );
function custom_order_list_column_content( $column, $post_id )
{

    // HERE get the data from your custom field (set the correct meta key below)
    $platform = get_post_meta( $post_id, 'platform', true );
    if( empty($platform)) $platform = '';

    switch ( $column )
    {
        case 'order_platform' :
            echo '<span>'.$platform.'</span>'; // display the data
            break;
    }
}

// MAKE 'PLATFORM' METAKEY SEARCHABLE IN THE SHOP ORDERS LIST
add_filter( 'woocommerce_shop_order_search_fields', 'platform_search_fields', 10, 1 );
function platform_search_fields( $meta_keys ){
    $meta_keys[] = 'platform';
    return $meta_keys;
}

代码进入您的活动子主题（活动主题或任何插件文件）的 function.php 文件中。

经过测试并且有效。
