D'OH

But it surely indicates the problem: $id should be in the recursion too.=

Assuming you translated your function's name and actually tree_vypis =3D=
=3D =

tree_list:

$trail =3D array(
1 =3D> '<drink_id>',
2 =3D> '<alcohol_id>',
3 =3D> '<beer_id>',
4 =3D> '<grolsch_id>'); //Grolsch!

function tree_list($parent=3D0,$level=3D1,$trail=3Darray()) {
// retrieve all children of $parent
$result =3D mysql_query("SELECT cname,cid FROM kategorie
WHERE parent=3D'{$parent}');
while ($row =3D mysql_fetch_assoc($result)) {
echo str_repeat('&nbsp;&nbsp;',$level).$row['cname']."<br/>\n";=

if ($row['cid'] =3D=3D $id[$level]) tree_list($row['cid'], =

$level+1,$trail);
}
}

tree_list(0,1,$trail);

Then again, the previous posted function would result in _less_ expansio=
n =

instead of more... (And a notice that $id did not exist, and certainly w=
as =

no array). Seems like someone did not post the exact function as actuall=
y =

used?
