Get user total purchased items count in Woocmmmerce - php

Question

I'm trying to figure out a function which get current user total number of purchased items (not total sum but items) across as all placed orders. So far I have found this (which doesn't work) - but again this function should get total sum and not items. Been trying to edit it to work but no success so far.
public function get_customer_total_order() {
$customer_orders = get_posts( array(
'numberposts' => - 1,
'meta_key' => '_customer_user',
'meta_value' => get_current_user_id(),
'post_type' => array( 'shop_order' ),
'post_status' => array( 'wc-completed' )
) );
$total = 0;
foreach ( $customer_orders as $customer_order ) {
$order = wc_get_order( $customer_order );
$total += $order->get_total();
}
return $total;
}
Any ideas?

Answer 1

Updated (Taking in account the item quantity)
The following very lightweight function will get the total purchased items count by a customer:
function get_user_total_purchased_items( $user_id = 0 ){
global $wpdb;
$customer_id = $user_id === 0 ? get_current_user_id() : (int) $user_id;
return (int) $wpdb->get_var( "
SELECT SUM(woim.meta_value)
FROM {$wpdb->prefix}woocommerce_order_items AS woi
INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS woim ON woi.order_item_id = woim.order_item_id
INNER JOIN {$wpdb->prefix}posts as p ON woi.order_id = p.ID
INNER JOIN {$wpdb->prefix}postmeta as pm ON woi.order_id = pm.post_id
WHERE woi.order_item_type = 'line_item'
AND p.post_type LIKE 'shop_order'
AND p.post_status IN ('wc-completed')
AND pm.meta_key LIKE '_customer_user'
AND pm.meta_value LIKE '$customer_id'
AND woim.meta_key LIKE '_qty'
" );
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.
USAGE Example
1) Display the current user total purchased items count:
<?php echo '<p>Total purchased items: ' . get_user_total_purchased_items() . '</p>'; ?>
2) Display the total purchased items count for a given user ID:
// Here the user ID is 105
<?php echo '<p>Total purchased items: ' . get_user_total_purchased_items(105) . '</p>'; ?>

function get_user_total_purchased_items_by_email( $email ){
global $wpdb;
if (empty($email)) {
return;
}
return (int) $wpdb->get_var( "
SELECT SUM(woim.meta_value)
FROM {$wpdb->prefix}woocommerce_order_items AS woi
INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS woim ON woi.order_item_id = woim.order_item_id
INNER JOIN {$wpdb->prefix}posts as p ON woi.order_id = p.ID
INNER JOIN {$wpdb->prefix}postmeta as pm ON woi.order_id = pm.post_id
WHERE woi.order_item_type = 'line_item'
AND p.post_type LIKE 'shop_order'
AND p.post_status IN ('wc-completed')
AND pm.meta_key LIKE '_customer_user'
AND pm.meta_value LIKE '$email'
AND woim.meta_key LIKE '_qty'
" );
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.
Usage Example
<?php echo '<p>Total purchased items: ' . get_user_total_purchased_items_by_email('youremail#mail.com') . '</p>'; ?>

Try this below code
global $wpdb;
$customer_orders = get_posts( array(
'numberposts' => - 1,
'meta_key' => '_customer_user',
'meta_value' => get_current_user_id(),
'post_type' => array( 'shop_order' ),
'post_status' => array( 'wc-completed' )
) );
$customer_orders = json_decode(json_encode($customer_orders),true);
$total_product_count = 0;
foreach ( $customer_orders as $customer_order_data ) {
$Order_ID=$customer_order_data['ID'];
$Select_Order_Details = $wpdb->get_results( "SELECT COUNT(order_item_id) AS total_product_count FROM {$wpdb->prefix}woocommerce_order_items WHERE order_item_type='line_item' and order_id = $Order_ID");
$Select_Order_Details = json_decode(json_encode($Select_Order_Details),true);
foreach($Select_Order_Details as $Product_Count)
{
$total_product_count=$total_product_count+$Product_Count['total_product_count'];
}
}
echo ($total_product_count); exit;
