I am building a website with Drupal 7, this website contains a blog. For some reasons I use a custom content type for blog posts call bog_post. In this content type I add a "Term reference" field (is machine name is "field_blog_categories").
To custom the layout of blog post I override node--blog_post.tpl.php. My problem is to display the term reference field. When I print the php var corresponding to that field "$field_blog_categories" I get :
Array ( [en] => Array (  => Array ( [tid] => 8 ) ) )
As you can see the term name don't appear. I thought to get the name by tid. I try
but it return nothing.
Any help to get the term name will be appreciate !
