Hi,
I’m developing a site that will contain news items and events. These are stored as resources within a certain resource container (two actually, one for news items and one for events). I wanted to use MM to streamline the creation of such resources so that only the required fields are displayed to non-administrator users.
I found a tip on another post for making rules sensitive to the parent id:
// Hides the field tvname for all docs whose parent isn’t id 28.
if($content[’parent’] != 28){
mm_hideFields(’tvname’,’2’);
}
from:

However, that doesn’t work for a resource that has just been created because $content[’parent’] hasn’t been set yet.
The parent id is obviously known - it is displayed on the resource’s page. So, I tracked down the manager code that generates the display of the resource parent and came up with this extended bit of code:
$parentId == 0;
if (isset($_REQUEST[’id’]))
{
$parentId = $content[’parent’];
}
elseif (isset($_REQUEST[’pid’]))
{
$parentId = $_REQUEST[’pid’];
}
if($parentId == <id of container>)
{
... conditional rules ...
}
So, thought I’d share this with the community ... for two reasons ... someone else might find it useful, and so that experienced MODx developers out there can have a look at it and tell me if its ok
Cheers,
Colin
