Questo ha fatto per me:
if (isset($_POST['isOrder']) && $_POST['isOrder'] == 1) {
$address = array(
'first_name' => $_POST['notes']['domain'],
'last_name' => '',
'company' => $_POST['customer']['company'],
'email' => $_POST['customer']['email'],
'phone' => $_POST['customer']['phone'],
'address_1' => $_POST['customer']['address'],
'address_2' => '',
'city' => $_POST['customer']['city'],
'state' => '',
'postcode' => $_POST['customer']['postalcode'],
'country' => 'NL'
);
$order = wc_create_order();
foreach ($_POST['product_order'] as $productId => $productOrdered) :
$order->add_product(get_product($productId), 1);
endforeach;
$order->set_address($address, 'billing');
$order->set_address($address, 'shipping');
$order->calculate_totals();
update_post_meta($order->id, '_payment_method', 'ideal');
update_post_meta($order->id, '_payment_method_title', 'iDeal');
// Store Order ID in session so it can be re-used after payment failure
WC()->session->order_awaiting_payment = $order->id;
// Process Payment
$available_gateways = WC()->payment_gateways->get_available_payment_gateways();
$result = $available_gateways[ 'ideal' ]->process_payment($order->id);
// Redirect to success/confirmation/payment page
if ($result['result'] == 'success') {
$result = apply_filters('woocommerce_payment_successful_result', $result, $order->id);
wp_redirect($result['redirect']);
exit;
}
}
Grande questione in effetti, mi è stato anche alla ricerca di una soluzione. – MrIndomitable
