Adding custom meta tags to nodes, dependent on author name?

Question

I would like to add the meta tag

`<meta name="robots" content="follow,noindex">`

to all nodes (content type is article) written by specific authors, not only for their new articles but for the few hundred that already exist.

I've installed metatag and metatags-quick, neither seem to offer the functionality I'm after. This is a drupal 7 installation.

I'd rather not have to edit the php, as I'm unfamiliar with that, but I will if I have to.

Does anyone know a way to do this?

I don't know of a metatag module which gives you that level of granularity; you might have to do it in code.

Fortunately, it's pretty easy. You'll need a custom module, in which you should implement hook_node_view(), and use drupal_add_html_head() to add the meta tag based on custom logic.

Very brief example:

function MYMODULE_node_view($node, $view_mode, $langcode) {
  if ($node->type == 'foo' && $view_mode == 'full') {
    if ($node->name == 'admin') {
      $tag = array(
        '#type' => 'html_tag',
        '#tag' => 'meta',
        '#attributes' => array(
          'name' => 'robots',
          'content' => 'follow,noindex',
        ),
      );
      drupal_add_html_head($tag, 'MYMODULE:robots:noindex');
    }
  }
}
