Conditionally display gateways

if you wanted to disable a gateway conditionally (lets say no cash on delivery for non logged in users) you could add this to your themes functions.php

wppizza_filter_gateways_orderpage

@param: array
@return: array

example:

add_filter('wppizza_filter_gateways_orderpage', 'my_custom_gateways_filter');
function my_custom_gateways_filter($gateways){
	/* disable Cash on delivery for non-logged in users */
	if( !is_user_logged_in()){
		unset($gateways['COD']);//gateway keys are always uppercase
	}
return $gateways;
}

wppizza_filter_gateways_payment_options

as of wppizza 3.2.5 you can also do something like the following to conditionally enable/disable gateways depending on order value

add_filter('wppizza_filter_gateways_payment_options', 'my_custom_gateways_on_zero', 10 , 3);
function my_custom_gateways_on_zero($gateway_objects, $order_data,  $user_data){

	/*
		just for convenience
	*/
	$cart_total = $order_data['summary']['total'][0]['value'];
	
	/* 
		Example:
		if cart total is zero, disable all credit card payment gateways 
		i.e simply keep COD (which must be enabled for this to work of of course)
	*/
	if(empty($cart_total)){
		foreach($gateway_objects as $id => $obj){	
			
			/* hint: you could - temporarily - do a print_r($id) here to see all the id's associated with any gateways you have enabled */
			
			if($id !== 'COD'){
				unset($gateway_objects->$id);	
			}
		}
	}

	/* 
		Example:	
		if cart total is > zeror, disable all NON credit card gateways - if that's what suits you
		you can use both examples in conjunctions with each other of course
	*/	
	if(!empty($cart_total)){
		unset( $gateway_objects->COD );
	}


return $gateway_objects;
}
