No redirect to status page if there is no action URL

[rvdsteege]

It is possible that there is no action URL when starting a payment, e.g. Direct Debit via Mollie (for which we create the token). In this case the user will not be redirected:

wp-pay-core/src/Plugin.php

Lines 539 to 590 in c743a15

	/**
	* Maybe redirect.
	*
	* @return void
	*/
	public function maybe_redirect() {
	// phpcs:disable WordPress.Security.NonceVerification.Recommended
	if ( ! \array_key_exists( 'payment_redirect', $_GET ) || ! \array_key_exists( 'key', $_GET ) ) {
	return;
	}
	// Get payment.
	$payment_id = (int) $_GET['payment_redirect'];
	$payment = get_pronamic_payment( $payment_id );
	if ( null === $payment ) {
	return;
	}
	// Validate key.
	$key = \sanitize_text_field( \wp_unslash( $_GET['key'] ) );
	if ( $key !== $payment->key || empty( $payment->key ) ) {
	return;
	}
	// phpcs:enable WordPress.Security.NonceVerification.Recommended
	Core_Util::no_cache();
	$gateway = $payment->get_gateway();
	if ( null !== $gateway ) {
	// Give gateway a chance to handle redirect.
	$gateway->payment_redirect( $payment );
	// Handle HTML form redirect.
	if ( $gateway->is_html_form() ) {
	$gateway->redirect( $payment );
	}
	}
	// Redirect to payment action URL.
	$action_url = $payment->get_action_url();
	if ( ! empty( $action_url ) ) {
	wp_redirect( $action_url );
	exit;
	}
	}

@remcotolsma should we add a fallback to redirect to the payment return redirect URL?

		// Redirect to payment return redirect URL.
		$return_redirect_url = $payment->get_return_redirect_url();

		if ( ! empty( $return_redirect_url ) ) {
			wp_redirect( $return_redirect_url );

			exit;
		}
