Add columns to admin orders list in WooCommerce - php

Question

I am using WooCommerce plugin for one of my ecommerce WordPress websites. I want to add some columns to my order listing page in the WooCommerce admin area. I am not able to find out where to add that.
Can anyone advise which template page I need to amend in order to meet my requirement?

So you if you want to add some columns in the orders Admin list page (in backend):
ADDING COLUMNS IN WOOCOMMERCE ADMIN ORDERS LIST
In the example below, we add 2 new custom columns, before existing "Total" and "Actions" columns.
// 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;
}
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.
