Hello everyone,
I'm hoping you guys can help me with this error. Here's what I'm getting:
Notice: Undefined variable: children in
L:\localhost\catalog\catalog_0.1.0\includes\classes\tree.class.php on line
58
This error occurs only when the class's method outputs $children as having a
value of zero. Below is the class. I want it to return zero but I don't want
this error. Do I need to change my error settings in my php.ini file? The
error level is currently set to E_ALL and I'm using PHP 5.0.1. If at all
possible, I want to keep this error setting at high because I want
everything to be coded strictly. What did I do wrong in my class and how can
I fix it to where it doesn't output an error when a class's method returns a
value of zero? Here's the class:
function get_children($parent) {
$parent_coord = tree::get_item_coord($parent);
$descendants = $this->get_descendants($parent);
Initialize $children here:
$children = array();
for ($i = 0; $i < count($descendants); $i++) {
if ((empty($children)) && (($parent_coord['0']['lft'] + 1) ==
$descendants[$i]['lft'])) {
$children[] = $descendants[$i]; // found first child
}
elseif (($children[count($children)-1]['rgt'] + 1 ==
$descendants[$i]['lft']) && $children[count($children)-1]['rgt'] + 1 !=
$parent_coord['0']['rgt']) {
$children[] = $descendants[$i]; // find next children
}
}
return $children;
}
Thanks in advance to anyone that can explain this error to me.
