Customizing file link in Drupal7 template

Question

I'm creating a custom layout (node--article.tpl.php) for a custom content type based on the Article type supplied in the base Drupal7 install. All I've added is a file attachment field for a PDF file.

I want to have a link in the rendered page that says something like ("PDF Version"). I've created a template file for that content type and it's working ok. I've used the print render($content['field_pdf']); code snippet to display the file link. It shows as the file's name as a link to the file with a PDF icon beside it. Almost perfect!

I just need to change the file's name to the static string "PDF Version".

Thanks in advance!

Use hook_node_view_alter()

function yourmodule_node_view_alter(&$build)
{
    $node = $build['#node'];
    if($node->type == "article" && isset($build['field_pdf']['#items']))
    {
        $build['field_pdf']['#items'][0]['#file']->filename = t('PDF Version');
    }
}

OR

function yourmodule_node_view_alter(&$build)
{
    $node = $build['#node'];
    if($node->type == "article" && isset($build['field_pdf']['#items']))
    {
        hide($build['field_pdf']);
        $build['my_themed_link']['#markup'] = l(t('PDF Version'), file_build_uri($build['field_pdf']['#items'][0]['uri']));
        $build['my_themed_link']['#weight'] = 10;
    }
}

I haven't tested that yet, hope it works for you.
