How to print parent taxonomy term name in a block?

Question

Using Drupal 7, I want to create a simple block that will be on all taxonomy term pages that will show the first parent of the current term (there will be a tree of parents, but I want just the next highest).

The below code works to pull the current term name, but I'm unsure how to go about pulling the parent term of this term page.

$current = taxonomy_term_load(arg(2));
if ($current):
echo $current->name;
endif;

Any suggestions?

Answer 1

I had to create a new question to get the answer (PHP is not my strong point).

$parent is actually an array, so it's output is a little different. There's likely many ways of doing it, but

echo reset($parent)->name;

worked for me.

You get the parent term with taxonomy_get_parents($tid). So you can just add:

$parent = taxonomy_get_parents($current->tid);
if ($parent){
  echo $parent->name;
}
