Improve this question I have created a custom payment gaeway where user can place order through whatsapp. When place order is clicked I want to open whatsapp url in the new tab and thank you page in same tab. I am stuck at sending the customer to the whatsapp url and at the same time open thank you page in same tab. Here is the full code of custom payment gateway: class WC_Gateway_WhatsApp extends WC_Payment_Gateway { public function __construct() { //... predefined variables add_action('woocommerce_update_options_payment_gateways_' . $this->id, array($this, 'process_admin_options')); } public function init_form_fields() { $this->form_fields = array( //...fields ); } public function payment_fields() { $order_id = absint( get_query_var( 'order-pay' ) ); $order = wc_get_order( $order_id ); echo '<p>' . esc_html__($this->description, 'woocommerce') . '</p>'; ?> <script type="text/javascript"> jQuery(document).ready(function($) { const form = $("form.checkout"); form.submit(function(e) { if (form.find("input[name='payment_method']:checked").val() === "whatsapp") { e.preventDefault(); const whatsappUrl = $('#whatsapp-url').data('url'); window.open(whatsappUrl, "_blank"); form.unbind('submit').submit(); } }); }); </script> <?php } public function process_payment($order_id) { $order = wc_get_order($order_id); $order->set_payment_method($this->id); $order->save(); $whatsapp_url = $this->generate_whatsapp_message($order); echo '<input type="hidden" id="whatsapp-url" data-url="' . esc_url($whatsapp_url) . '" />'; return array( 'result' => 'success', 'redirect' => $this->get_return_url($order) ); } private function generate_whatsapp_message($order) { $customer_name = $order->get_billing_first_name() . ' ' . $order->get_billing_last_name(); $whatsapp_message = "Order from " . $customer_name . ":\n"; $whatsapp_message .= "Order Id = " . $order_id . "\n"; //...other message $whatsapp_number = $this->number; $whatsapp_url = 'https://wa.me/' . $whatsapp_number . '?text=' . urlencode($whatsapp_message); return $whatsapp_url; } }
