Prevent Proforma Invoice Emails being sent to certain clients

[craigedmonds]

I am working on a hook using EmailPreSend to prevent proforma invoice emails being sent to the client. (what we do is on the first of each month, for some clients, we merge all their proforma invoices into one invoice and send them the main invoice).

However, I am stuck on understanding the var for "messagename". Really the API docs do not explain it very well at all.

What would the message name be for $vars['messagename'] ??

Any ideas folks?

<?php
/*
see: https://developers.whmcs.com/hooks-reference/everything-else/#emailpresend
*/

//prevent someone accessing this file directly
if (!defined("WHMCS")) die("This file cannot be accessed directly");
	
add_hook('EmailPreSend', 1, function($vars) {

	//if this is the proforma invoice about to be sent we need to check if there
	//is any clients we DONT want to send proforma emails to
	if ($vars['messagename'] == 'My Message Name') {
	
		//this will be the proforma invoice number
		$relid = $vars['relid'];
		
		//list of client id's I DO NOT want to send proforma emails to
		$clients = array(
		"111",
		"222",
		);
	
		//need to get the clientid from $relid
		$sql = "SELECT userid FROM tblinvoices WHERE id = $relid";
		$result = full_query($sql);
		$data = @mysql_fetch_array ($result);
		$userid = $data['userid'];
		
		//check if userid is to NOT receive proforma emails
		if(in_array($userid, $clients)){
	   		$merge_fields['abortsend'] = true;
			return;
	 	}

    }

});

//end of hook
?>
