wc_customer_bought_product error

Hello Authors,

I have faced the same issue for wc_customer_bought_product. After debugging your plugin code, found that there is one parameter missing in SQL.

$result = $wpdb->get_var(
$wpdb->prepare( “
SELECT 1 FROM {$wpdb->posts} AS p
INNER JOIN {$wpdb->postmeta} AS pm ON p.ID = pm.post_id
INNER JOIN {$wpdb->prefix}woocommerce_order_items AS i ON p.ID = i.order_id
INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS im ON i.order_item_id = im.order_item_id
WHERE p.post_status IN ( ‘wc-completed’, ‘wc-processing’ )
AND pm.meta_key IN ( ‘_billing_email’, ‘_customer_user’ )
AND im.meta_key IN ( ‘_product_id’, ‘_variation_id’ )
AND im.meta_value = %d
“, $product_id
) . ” AND pm.meta_value IN ( ‘” . implode( “‘,'”, $customer_data ) . “‘ )”
);

SELECT 1 should be replaced with SELECT COUNT( DISTINCT i.order_item_id ).

I hope we will get this fixed as soon as possible.
