Total purchase count by product for current user i

问题:

In Woocommerce, I would like to show the total purchase product count for the current user in single product pages. Like for example if John bought a Pen 2 times then it displays the count ("2") in this product page for John user and if Jack bought it 5 times then it will show 5 in this product page for Jack user.

I don't want print total sold count, I want to show as per current logged in user.

My actual code in function.php file:

add_action( 'woocommerce_single_product_summary', 'wc_product_sold_count', 11 );
function wc_product_sold_count() {
    $get_current_pro_id = $_SESSION["iddd"];

    global $product;
    $current_user = wp_get_current_user();

    if ( wc_customer_bought_product( $current_user->user_email, $current_user->ID,  $product->get_id() )  )
    {

        $units_sold = get_post_meta( $product->id, 'total_sales', true );
//echo '<p>' . sprintf( __( 'Units Sold: %s', 'woocommerce' ), $units_sold ) . '</p>';

        return $units_sold;
    }
}

That can be done easily with a very light SQL query in your hooked function:

add_action( 'woocommerce_single_product_summary', 'wc_product_sold_count', 11 );
function wc_product_sold_count() {
    // Only for logged in users
    if ( ! is_user_logged_in() ) return; // Exit for non logged users

    global $wpdb, $product;

    $user_id = get_current_user_id(); // Current User ID
    $product_id = $product->get_id(); // Current Product ID

    // The SQL request
    $units_bought = $wpdb->get_var( "
        SELECT SUM(woim2.meta_value)
        FROM {$wpdb->prefix}woocommerce_order_items AS woi
        INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta woim ON woi.order_item_id = woim.order_item_id
        INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta woim2 ON woi.order_item_id = woim2.order_item_id
        INNER JOIN {$wpdb->prefix}postmeta pm ON woi.order_id = pm.post_id
        INNER JOIN {$wpdb->prefix}posts AS p ON woi.order_id = p.ID
        WHERE woi.order_item_type LIKE 'line_item'
        AND p.post_type LIKE 'shop_order'
        AND p.post_status IN ('wc-completed','wc-processing')
        AND pm.meta_key = '_customer_user'
        AND pm.meta_value = '$user_id'
        AND woim.meta_key = '_product_id'
        AND woim.meta_value = '$product_id'
        AND woim2.meta_key = '_qty'
    ");

    // Display count if is greater than zero
    if( $units_bought > 0 ){
        $label = __( 'Units bought' , 'woocommerce' ); // Label

        // Output
        echo '<p class="units-bought"><strong>' . $label . ': </strong>' . $units_bought . '</p>';
    }
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.
