@ Fabrice
you know, It would be really helpful to you if I would actually read better!
Here’s a link to the function you’re using:
https://github.com/Connections-Business-Directory/Connections/blob/8.1.3/includes/class.terms.php#L1022
The phpDoc for the function starts here:
https://github.com/Connections-Business-Directory/Connections/blob/8.1.3/includes/class.terms.php#L883
So my error, again, is providing you with the wrong way to use the function … it should be:
$terms = cnTerm::get( 'category', array( 'child_of' => 3 ) );
I wrote the code but I don’t actually use it, yet, and it’s been a couple months since I did write it, so I’m just forgetting how it works. It’s no excuse for the bad info I’m giving you but it is the reason. I apologize! And if I’m wrong again, hopefully the phpDoc I linked to will give you the answers you need assuming I have no errors in it.
