currently you can’t do that in EE4. That feature has been requested previously and we do have plans to implement it, although there is no current estimated delivery date.

It might be possible if you’re willing to tweak some of the single page checkout code. Basically you would just see what event the user has registered for, and then hide the check gateway if it’s no in the list of allowed events. Would you like some tips on how to do that?

sorry I was hoping the developer who deals more with single page checkout would be able to comment in, but he’s pretty swamped.

in ee4, early on in the page loading process all the gateways are constructed and add a callback on the ‘AHEE__display_payment_gateways’ action, so that when that action is fired (ie ‘do_action’) in the modules/single_page_checkout/templates/registration_page_payment_options.template.php, each active gateway’s espresso_display_payment_gateways() method is called, which echoes out the HTML to add the gateway as an option.
So you can either try to temporarily make a gateway ‘inactive’ based on the events in the cart BEFORE any of the gateways are constructed and hook into ‘AHEE__display_payment_gateways’, OR you can try to remove the gateways callbacks on that action before it is called. I’m inclined to try the latter.

So on an earlier than ‘AHEE__display_payment_gateways’, like ‘AHEE__registration_page_payment_options__payment_info_table_amount_owing_row_end’ (which is also in the same template file, just a few lines earlier), you could run some code like the following:

add_action('AHEE__registration_page_payment_options__payment_info_table_amount_owing_row_end', 'espresso_hide_gateways_for_certain_events');
function espresso_hide_gateways_for_certain_events(){
	$events_which_dont_use_invoice = array( 9, 23 );
	foreach( EE_Cart::instance()->get_tickets() as $ticket_line_item){
		$ticket_obj = $ticket_line_item->ticket();
		if( $ticket_obj instanceof EE_Ticket ){
			$datetimes = $ticket_obj->datetimes();
			foreach( $datetimes as $datetime ){
				if( in_array( $datetime->get('EVT_ID'), $events_which_dont_use_invoice ) ){
					espresso_dont_show_certain_gateways();
				}
			}
		}
	}
}

function espresso_dont_show_certain_gateways(){
	$gateway_class_names_to_not_show = array('EE_Check');
	foreach( EEM_Gateways::instance()->get_gateway_instances() as $gateway){
		if( in_array( get_class($gateway), $gateway_class_names_to_not_show) ){
			remove_action('AHEE__display_payment_gateways', array( $gateway, 'espresso_display_payment_gateways'));
		}
	}
}

This code could be inserted into your theme’s functions.php file.

If users have registered for an event with ID 9 or 23, it will hide the Check gateway. So if you wanted it to include different events you’d have to manually change that array of IDs, or if you wanted to hide different gateways you’d have to change the array used in espresso_dont_show_certain_gateways() too.

You might want to add more logic about how those arrays are chosen. For example, you could get the list of events using a database query, searching for events with a particular postmeta value (it would probably be easiest to use get_posts() for this)
