Redirect user to specific page if Manual/Offline gateway is selected

This will redirect the user to a page with payment information in case he selects the Manual/Offline payment gateway.

add_action('pms_get_redirect_url', 'pmsc_redirect_after_manual_payment');
function pmsc_redirect_after_manual_payment( $url ) {
	if( !isset( $_POST['pay_gate'] ) || $_POST['pay_gate'] != 'manual' )
		return $url;

	$subscription_plan = pms_get_subscription_plan( $_POST['subscription_plans']);

	if( !isset( $subscription_plan->id ) || $subscription_plan->price == 0 )
		return $url;
	else
		return home_url('/payment-info');
}

The page slug can be modified on this line: return home_url('/payment-info');

In case you are using the Profile Builder form and you want to do this redirect, you will need to add these 2 lines of code as well:

add_filter( 'wppb_after_success_email_confirmation_redirect', 'pmsc_redirect_after_manual_payment' );
add_filter( 'wppb_register_redirect', 'pmsc_redirect_after_manual_payment' );
