Login to view full article (anonymous users see teasers)

Ok, it's a little late, but here it is.
This isn't a tutorial, its an example of what I've done - you'll have to create your own categories, and roles to make this your own - but the code all works.

I'm running 4.7.
I have roles setup for Authors, and for subscribers. I also have different categories assigned as feeds that users can "subscribe" to. This script shows the page while in "preview" mode, like on lists and the home page, then when displaying the full page, it checks that you're a subscriber and acts accordingly.

This also requires that you use the -- drupal break -- feature to break the story. I'm not sure if it works if you use the automatic teaser feature.

The following code goes into your node.tpl.php and replaces the code that shows the page's content.

Hope this helps others out there!

/* Setup our environment */
$pagecontent = '<div class="submitted">' . $date . " by ". $authorship . '</div>' . '<div class="nodecontent">' . $content . '</div><div class="node-options">' . theme('links', $node->links) . '</div>';
$nid = $node->nid;
$taxonomy_term = taxonomy_node_get_terms($nid);
$taxonomy_id = array_keys($taxonomy_term);
/* Set the isAuthor flag - on my site I have authors that I grant all access to. */ 
if (array_search("Author-Staff Writer",$user->roles) == "") { $isAuthor = FALSE; } else { $isAuthor = TRUE;}


if (arg(0)!="node") {
	/* if the page is being displayed in any other format that on it's own, show conent (in this case the teaser) */
	print $pagecontent;
} else {
	if ( 
	/* 
	 * list of items that you *want* visible to everyone logged-in or not 
	 * The numbers used here are category IDs.		
	 */
	$isAuthor != FALSE ||
	current($taxonomy_id) =="4" /* About us Pages */ || 
	current($taxonomy_id) =="5" /* News Pages */ ||
	current($taxonomy_id) =="6" /* Polls */ || 
	$user->uid!="0" /* is not the main site Admin */
	) {
		print $pagecontent;
	} else {			

		if ($user->uid=="0") {
			/* User not logged in - show a message */
			echo "<h2>Please register or log-in to view this posting<h2>";
			include($error_message);
		} else {
			/* 
			 * Now we made usre they are logged-in, we check if they are a subscriber to the article being shown 
			 * This uses the drupal user roles to determine if they are subscribers
			 */
			switch (current($taxonomy_id)) {
				case '1':
					if (array_search('Subscriber (Monthly)', $user->roles)) { $authorized = TRUE; } else { $authorized = FALSE;}
					break;
				case '2':
					if (array_search('Subscriber (Weekly)', $user->roles)) { $authorized = TRUE; } else { $authorized = FALSE;}
					break;
				case '3':
					if (array_search('Subscriber (Digest)', $user->roles)) { $authorized = TRUE; } else { $authorized = FALSE;}
					break;
				}
			if ($authorized==FALSE) {
				/* They are logged in, but do not subscribe to this particular feed, let them know */
				echo "<h2>You are logged in, but do not subscribe to this feed. Please contact us to become subscribed to this feed.<h2>";
			} else {
				/* Finally, all is good, show the page content */
				print $pagecontent;
			}
		}
	}
