accessing $etomite from within an included class

If I want to create a php class, which I include using:

if (!class_exists("ListMenuX")) { include "assets/snippets/listmenux/listmenux.inc.php"; }

how can I then, within the included class, access my $etomite instance? Currently, when trying to call $etomite->getActiveChildren() from within a function in my class like so:

function getChildList($parentId)
{
$listArray = false;
if (!$parentId===false) { $listArray = $etomite->getActiveChildren($parentId); }
return $listArray;
}

I get the error:

Fatal error: Call to a member function on a non-object in /home/sallen/public_html/thevirtualhandshake/assets/snippets/listmenux/listmenux.inc.php on line 53

Any suggestions on the proper way to approach this in the framework?

Hi,

Here's a quick solution:

1) you can use the global keyword to make $etomite global

2) you can pass the $etomite variable to the class constructor and assign it as a variable of the class:

$lm = new ListMenuX($etomite);

from inside the constructor:

function ListMenuX($etomite) {
$this->etomite = $etomite;
}

Thanks xwisdom, that worked like a charm. I had actually tried that just before posting, but had accidentally tried to call the function with

$this->$modx->getActiveChildren($parentId)

which of course didn't work, since I included the $ before modx.
shocked
