WC_Customer Class - WooCommerce

Overview

The WC_Customer class represents a customer in WooCommerce. It manages customer data including billing/shipping addresses, user account linkage, and session data for guest customers.

// Get total spent
$total_spent = wc_get_customer_total_spent( $customer->get_id() );

// Get last order
$last_order = wc_get_customer_last_order( $customer->get_id() );

    $customer->set_billing_email( 'guest@example.com' );
    $customer->set_billing_country( 'US' );
    $customer->save(); // Saves to session
}

// Session data persists across page loads

Checking Guest vs Registered

$customer = WC()->customer;

if ( $customer->get_id() > 0 ) {

// Check role
if ( in_array( 'customer', $user->roles ) ) {
    // Is a customer
}

if ( in_array( 'administrator', $user->roles ) ) {
    // Is an admin
}

Adding Customer Role

$customer_id = 123;
$user = get_user_by( 'id', $customer_id );

// Add customer role
$user->add_role( 'customer' );

// Remove role
$user->remove_role( 'subscriber' );

$customer = new WC_Customer( 123 );

// Get downloadable products

    echo $download['download_url'];
    echo $download['downloads_remaining'];
}

    // Email already registered
