return View::make('home')->with(array('posts' => $posts));
The above is working for me, so I think I know how to pass more than one variable.
What I'm interested in doing is both passing a dataset of all posts to my view, but I also want to pass a count on how many comments are related to each post.
$posts = Post::orderBy('id', 'desc')->paginate(5);
And then something to extract from the db a number representing how many comments are marked in the table with each id.
I'm interested in displaying the text: "Comments (x)" under each post, with X being the number of comments that post has recieved.
Providing you have your relationship between posts and comments set up correctly, you can simply pass the posts.
If you are then looping through the posts using say,
foreach ($posts as $post)
then each post contains a post object and post->comments will contain a collection of comments for that post.
As collections have a count() method, you can round this off by adding
Comments ({{ $post->comments->count() }})
to your view.

That is exactly what I'm looking for. But how do I make sure I have the correct setup?
Building the db from migrations I was unable to use foreign keys. It gave me an error I was unable to resolve.
Am I correct in assuming I need to fix my db setup to include foreign keys?
You would setup your Comments table to have a post_id column. That would be your key. Then you would setup the relationship:
// Posts model
$this->hasMany('Comment');
// Comments model
$this->belongsTo('Post');
It maybe your database doesn't support foreign keys as an index, but setting a column name with an id from the other table will be similar.
Where in the above do you point to the column post_id as being the fk we're interested in? How would it know?
protected $table = 'posts';
protected $primaryKey = 'id';
$this->hasMany('Comment');
The above gives me an error: syntax error, unexpected '$this' (T_VARIABLE), expecting function (T_FUNCTION)
It seems I just got the structure wrong. I found my answer here: http://laravel.com/docs/eloquent#one-to-many
Thank you for the help!
