Updated: 2018-03-30 – added positioning feature to the new columns

因此,如果要在订单管理员列表页面(后端)中添加一些列,请执行以下操作：

在WOOCOMMERCE ADMIN ORDERS列表中添加列

在下面的示例中,我们在现有的“Total”和“Actions”列之前添加了2个新的自定义列.

// ADDING 2 NEW COLUMNS WITH THEIR TITLES (keeping "Total" and "Actions" columns at the end)
add_filter( 'manage_edit-shop_order_columns','custom_shop_order_column',20 );
function custom_shop_order_column($columns)
{
    $reordered_columns = array();

    // Inserting columns to a specific location
    foreach( $columns as $key => $column){
        $reordered_columns[$key] = $column;
        if( $key ==  'order_status' ){
            // Inserting after "Status" column
            $reordered_columns['my-column1'] = __( 'Title1','theme_domain');
            $reordered_columns['my-column2'] = __( 'Title2','theme_domain');
        }
    }
    return $reordered_columns;
}

// Adding custom fields Meta data for each new column (example)
add_action( 'manage_shop_order_posts_custom_column','custom_orders_list_column_content',20,2 );
function custom_orders_list_column_content( $column,$post_id )
{
    switch ( $column )
    {
        case 'my-column1' :
            // Get custom post Meta data
            $my_var_one = get_post_meta( $post_id,'_the_Meta_key1',true );
            if(!empty($my_var_one))
                echo $my_var_one;

            // Testing (to be removed) - Empty value case
            else
                echo '<small>(<em>no value</em>)</small>';

            break;

        case 'my-column2' :
            // Get custom post Meta data
            $my_var_two = get_post_meta( $post_id,'_the_Meta_key2',true );
            if(!empty($my_var_two))
                echo $my_var_two;

            // Testing (to be removed) - Empty value case
            else
                echo '<small>(<em>no value</em>)</small>';

            break;
    }
}
