Allow block display on child nodes but not grandchildren

Question

In a block configuration, I would like to show the block on /programs/* but not on programs/* /*

I have seen a number of questions similar to mine. Block display using wildcard, non-greedy for example.

The recommendation from the above link to use drupal_match_path() makes the most sense to me. I have implemented the following,

    <?php
if (drupal_match_path(current_path(), "programs/*") && !arg(2)) {
  return TRUE;
}
?>

expecting the block to appear on /projects/name but not on /projects/name/grandchild-node. The block doesn't appear anywhere. Just to test the system, I tried this:

    <?php
if (drupal_match_path(current_path(), "programs/*") {
  return TRUE;
}
?>

and still the block doesn't show. I'm certain that I'm doing something wrong that is very basic. Any ideas?

Hmm. Are you sure current_path() is returning the alias? cause I don't think match_path takes that in to consideration at all.

$path = current_path(); $path_alias = drupal_lookup_path('alias',$path);
