Wordpress Taxonomies - wordpress

Question

I'm about ready to cry!
I've done a lot of Google searches but I can't quite get this piece of coding working the way I want it to.
In Wordpress I have the following taxonomy:
Active
- Open
- In-Progress
- Awaiting Parts
- Pending / On-Hold
- Awaiting Pick-up
Closed

What I would like is for the child to be displayed for the specific post and if there are no children I would like to display just the parent.
Heres a screenshot I've edited so it gives a better picture of what I'm asking.

This is the code I've been playing with:
$terms = wp_get_post_terms($post->ID, 'pctracker_workorderstatus');
$count = count($terms);
if ( $count > 0 ){
foreach ( $terms as $term ) {
echo $term->name .'<br>';
}
}
At present its displaying the parent and child for the post.
Would be very grateful for some help or direction!
Thanks,
Jase

You'll have to edit column content like this :
This is an example code you could adapt to your needs, basically I look at all terms to get which ones are parents and childs. Then depending of the results I display parents or childs. In your case, there will always be 1 parent and/or 1 child. But the code should work. (not tested)
function MYCUSTOMPOSTTYPE_custom_columns( $column_name, $id ) {
switch ( $column_name ) {
case 'status':
$terms = wp_get_post_terms($id, 'pctracker_workorderstatus');
$count = count($terms);
if ( $count > 0 ) {
$parents = array();
$childs = array();
foreach ( $terms as $term ) {
if(!empty($term->parent)) {
$childs[] = $term;
} else {
$parents[] = $term;
}
}
//display parent if there no child
if(empty($childs)) {
foreach($parents as $p) {
echo $p->name;
}
} elseif(!empty($parents) && !empty($childs)) {
//don't display parent
foreach($childs as $p) {
echo $p->name;
}
}
}
break;
default:
break;
} // end switch
}
add_action( 'manage_MYCUSTOMPOSTTYPE_posts_custom_column', 'MYCUSTOMPOSTTYPE_custom_columns', 10, 2 );
