OK. Experimenting. Tried setting up a snippet with the following to test if getparent was working:
$id = $modx->documentIdentifier;
$pid = $modx->getParent($id,1,’id’);
return $pid;
On the root page I get nothing and on pages inside folders I get "Array". What am I doing wrong?
I can print $id to the page if I return $id but can’t get $pid!
Does it matter if I have se friendly urls? Does getParent work if the parent is a folder? Does it matter?
My page structure is:
root page
about (folder)
page 1
page 2
page 3
services (folder)
page 1
page 2
page 3
products (folder)
page 1
page 2
page 3
If that helps someone to troubleshoot!
Thanks!
getParent returns an array, since usually you’ll have more than one item to be returned in the "fields" part of the arguments. So you should have
$id = $modx->documentIdentifier;
$pdata = $modx->getParent($id,1,'id');
$pid=$pdata['id'];
return $pid;

You know what . . . you consistently point me in the right direction, both in your replies to my posts and in the threads I’ve read that you’ve either started or replied to. Thank you!
You know, "parent" is a regular part of any document; outside of snippets or TVs with PHP code you can use [*parent*], inside you can almost always use $modx->documentObject[’parent’]. I frequently use [*parent*] as the value for the DropMenu snippet’s startDoc argument.
There are some cases where the documentObject may not be available, though, such as in a plugin that acts on the OnWebPageInit event, which is triggered before the documentObject array is set, and then you’d need to use your function.

I’m just getting to grips with snippets and tvs at the moment . . . haven’t even touched plugins yet. Thanks for the info though! This thing is awesome. I’m looking at the stuff that it can do, thinking "Ah, but I bet it can’t do that". Five minutes later, I find that it can!
Awesome!
document.parser.class.inc.php makes for great bedtime reading
