Client Area Sidebar - Error

[Qhiliqq]

Hi,

I created a new hook, which should add the username of the user to Client Details sidebar.
Yes usernames, I got an extra module for that.

My php look like this:

<?php

use WHMCS\View\Menu\Item as MenuItem;

add_hook('ClientAreaPrimarySidebar', 1, function(MenuItem $primarySidebar)
{
	$specialTXT = <<<EOT
	Test
EOT;
	
	$primarySidebar->getChild("Client Details")->setBodyHtml($specialTXT);
});

But now my whole "nonuser" Website stops working...
Error in logs:

[Sun Feb 25 17:12:30.531758 2018] [:error] [pid 29143] [client xxx.xxx.249.xxx:62288] [WHMCS Application] ERROR: exception 'Whoops\\Exception\\ErrorException' with message 'Call to a member function setBodyHtml() on null' in /xxx/includes/hooks/ClientAreaSidebar.php:8 Stack trace: #0 /xxx/vendor/whmcs/whmcs-foundation/lib/Utility/Error/Run.php(0): WHMCS\\Utility\\Error\\Run->handleError(1, 'Call to a membe...', '/xxx...', 8) #1 [internal function]: WHMCS\\Utility\\Error\\Run->handleShutdown() #2 {main} {"exception":"[object] (Whoops\\\\Exception\\\\ErrorException(code: 1): Call to a member function setBodyHtml() on null at /xxx/includes/hooks/ClientAreaSidebar.php:8)"} []

Also I just want to add something and not change the whole field...

Regards

the golden rule with sidebar/navbar hooks is that you HAVE to check that the item exists before you try to change/remove it - so you're hook would work fine on the client's homepage (because the sidebar exists), but on any other page, it won't exist and therefore you're trying to modify something that isn't there.

take a look at the hook below - that might be a better starting point for you.

then it's just a case of working out how to get the usernames - which I guess will either be a custom field, or in a database table somewhere.
