passing multiple queries to view with codeigniter - codeigniter

Question

I am trying to build a forum with Codeigniter.
So far i have the forums themselves displayed and the threads displayed, based on the creating dynamic news tutorial.
But that is 2 different pages, i need to obviously display them into one page, like this:
Forum 1
- thread 1
- thread 2
- thread 3
Forum 2
- thread 1
- thread 2
etc.
And then the next step is obviously to display all the posts in a thread. Most likely with some pagination going on. But that is for later.
For now i have the forum controller (slimmed version):
<?php
class Forum extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('forum_model');
$this->lang->load('forum');
$this->lang->load('dutch');
}
public function index()
{
$data['forums'] = $this->forum_model->get_forums();
$data['title'] = $this->lang->line('title');
$data['view'] = $this->lang->line('view');
$this->load->view('templates/header', $data);
$this->load->view('forum/index', $data);
$this->load->view('templates/footer');
}
public function view($slug)
{
$data['forum_item'] = $this->forum_model->get_forums($slug);
if (empty($data['forum_item']))
{
show_404();
}
$data['title'] = $data['forum_item']['title'];
$this->load->view('templates/header', $data);
$this->load->view('forum/view', $data);
$this->load->view('templates/footer');
}
}
?>
And the forum_model (also slimmed down)
<?php
class Forum_model extends CI_Model {
public function __construct()
{
$this->load->database();
}
public function get_forums($slug = FALSE)
{
if ($slug === FALSE)
{
$query= $this->db->get('forum');
return $query->result_array();
}
$query = $this->db->get_where('forum', array('slug' => $slug));
return $query->row_array();
}
public function get_threads($forumid, $limit, $offset)
{
$query = $this->db->get_where('thread', array('forumid', $forumid), $limit, $offset);
return $query->result_array();
}
}
?>
And the view file
<?php foreach ($forums as $forum_item): ?>
<h2><?=$forum_item['title']?></h2>
<div id="main">
<?=$forum_item['description']?>
</div>
<p><?=$view?></p>
<?php endforeach ?>
Now that last one, i would like to have something like this:
<?php foreach ($forums as $forum_item): ?>
<h2><?=$forum_item['title']?></h2>
<div id="main">
<?=$forum_item['description']?>
</div>
<?php foreach ($threads as $thread_item): ?>
<h2><?php echo $thread_item['title'] ?></h2>
<p><?=$view?></p>
<?php endforeach ?>
<?php endforeach ?>
But the question is, how do i get the model to return like a double query to the view, so that it contains both the forums and the threads within each forum.
I tried to make a foreach loop in the get_forum function, but when i do this:
public function get_forums($slug = FALSE)
{
if ($slug === FALSE)
{
$query= $this->db->get('forum');
foreach ($query->row_array() as $forum_item)
{
$thread_query=$this->get_threads($forum_item->forumid, 50, 0);
}
return $query->result_array();
}
$query = $this->db->get_where('forum', array('slug' => $slug));
return $query->row_array();
}
i get the error
A PHP Error was encountered
Severity: Notice
Message: Trying to get property of non-object
Filename: models/forum_model.php
Line Number: 16
I hope anyone has some good tips, thanks!

*EDIT***
Thanks for the feedback.
I have been puzzling and this seems to work now :)
$query= $this->db->get('forum');
foreach ($query->result() as $forum_item)
{
$forum[$forum_item->forumid]['title']=$forum_item->title;
$thread_query=$this->db->get_where('thread', array('forumid' => $forum_item->forumid), 20, 0);
foreach ($thread_query->result() as $thread_item)
{
$forum[$forum_item->forumid]['thread'][]=$thread_item->title;
}
}
return $forum;
}
What is now next, is how to display this multidimensional array in the view, with foreach statements....
Any suggestions ?
Thanks

Answer 1

You are using row_array() hence your error, change your get_forums() to:
$thread_query=$this->get_threads($forum_item['forumid'], 50, 0);
But I believe you should actually be using result_array() since you want a list of all forums.
