    <p>You should not issue redirects when there is an access denied. That is a logical error in any web-framework. You should issue an "access denied" when you want to deny access. Just like you issue a "the content has moved there, please go there" when your content has moved. </p> <p>Instead of <code>drupal_goto()</code>, use <code>drupal_access_denied()</code>. If you truly want people to be redirected to another url, the place to do that, would be <strong>on the page that shows the denied access</strong>.</p> <p>That said, issuing a <code>drupal_access_denied()</code>, or, in fact, sending any header in <code>hook_init()</code> is plain wrong. From the <a href="http://api.drupal.org/api/drupal/developer--hooks--core.php/function/hook_init/6" rel="nofollow">documentation</a>: «Perform setup tasks.» Sending headers is <em>not</em> a setup-task. Moreover, that same documentation warns about another potential problem with your approach: «This hook is not run on cached pages», in other words, once an adult visits a page, and it is cached, underaged visitors will not be redirected or denied access, they will get the cached page served.</p> <p>Now, on to what you <em>should</em> do: A module such as Taxonomy Access (Lite) or the more appropriate <a href="http://drupal.org/project/node_privacy_byrole" rel="nofollow">Node Privacy By Role</a> can be used to grant access to your content. Note that, by default, Views will not use these access: they will show lists of content, regardless of the access by the user: you will have to reconfigure all your views to either honor the access-rules or to be inaccassible entirely, to certain roles. In addition, you need to give "minors" a separate role: that way you can grant them different access then the people in rol "authenticated user" or even in "adult". You will need some mechanism to <a href="http://drupal.org/project/autoassignrole" rel="nofollow">automatically assign roles</a>.</p>

    1. COI appreciate the thought that went into your answer, but you are answering a question that wasn't asked while making way too many assumptions about the app, its content, how the content is delivered, and the module that controls the age access. There's just absolutely no need for the modules you are recommending. For example, users are anon, content is public, and the access denied won't always be because an age was not verified. Might be good suggestions for someone building an authenticated user based app though.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
