I could have sworn that references and I used to get along...
In the menu::hasChild method, I cant seem to reference $this->_data.
$this->_data is supposed to be a reference to the original array $array
in the local scope.
The only way to make this script work is to call on the $GLOBALS array
in menu::hasChild.
Could anyone explain to me, why I'm unable to use $this->_data
in menu::hasChild?
Nevermind. I figured what was causing the problem...
