Lately I was assigned with the task to display all terms assigned to a node, grouped by their parent. To better explain this, let's say for example that we have the Vocabulary 1 assigned to Content Type A, with the following terms:

Parent 1

-- term 1

-- term 2

-- term 3

Parent 2

-- term 4

-- term 5

Parent 3

-- term 6

-- term 7

etc. 

If we need to display a block in user pages, and not in /user/login or /user/register etc pages, we need to field in some custom php code under the Page specific visibility settings, we select the radio "Show if the following PHP code returns TRUE (PHP-mode, experts only)" and we fill in the following code:

After a fresh drush installation, drush status returned this error message:

sudo mkdir /usr/local/share/
sudo mkdir /usr/local/bin/

While working on an extra requirement for metalera.gr, we needed to do the following:

When viewing node/xxx, we would like to display all nodes that have terms that belong to the same parent as the one we currently visit. Let's say for example, that we have the following parent:

Colors

--red

--blue

--green

Node/xxx has the term green assigned. We need our view to display all nodes that have red or blue as well. 

To achieve that, we first create a new view, then:  

In Drupal 6 there is a very easy way to exclude the current node from the views output.
