Trying to show a single blog post - El Forum - 05-20-2010

For some reason this brings up a blank page. That's weird because it should at least load my header and footer.
I'm assuming it's passing false for some reason because $blod_id does not have a value? My read more links look like this:
Code:
echo anchor('blog/view/'.$row->blogId, 'Read on');Trying to show a single blog post - El Forum - 05-20-2010

Well $row->blogId should contain the id right? Ofcourse it doesnt work if theres no id
Does it work if you just use url http://www.yourdomain.com/blog/view/12 (or any other id that exists).

The link points to the correct ID. I'm really not sure what's going on here. The database returns results correctly if I just do a simple get('blogposts') active record query.

Just add this to the view method:
Code:
$this->output->enable_profiler(TRUE);That will tell you the queries run + much more.

Weird. No URI data, no queries. Nothing seems to be happening at all. Any ideas?

That is weird. Does that profiler give you anything in other controllers?

Nope. Under class/method it says blog/view
Everything else is either benchmarks/memory usage or is empty.

Do you use routes? Thats the only thing that I can think of.. Maybe you should paste the whole controller here so we can have a looksee.

Here's the controller blog.php
Code:
<?php
// Blog controller
class Blog extends Controller
{
function __construct(){
parent::Controller();
$this->load->model('blogmodel');
$this->load->helper('text');
}
function index(){
$data['posts'] = $this->blogmodel->get_recent_entries(); // Get blog posts
$data['content'] = 'blogview';
$this->load->view('includes/template', $data);
}
function view($blog_id = FALSE) {
$this->output->enable_profiler(TRUE);
if (!$blog_id)
{
return FALSE;
}
$data['post'] = $this->blogmodel->get_view($blog_id);
if (!$data['post'])
{
// Maybe check the $data['post'] here and load a error view for non existing blogid
$this->load->view('error_404');
return FALSE;
}
$data['content'] = 'postview';
$this->load->view('includes/template', $data);
}
}
?>And this is the entire model file at blogmodel.php
Code:
<?php
// Blog model
class BlogModel extends Model{
function Blogmodel() {
parent::Model();
}
function get_recent_entries()
{
$query = $this->db->get('blogposts', 10);
return $query->result();
}
function get_view($blog_id)
{
$this->db->where('blogId', $blog_id);
$query = $this->db->get('blogposts');
if ($query->num_rows() == 1) {
return $query->result();
}
return FALSE;
}
}

Only thing I see here that could cause problems(but I doubt) is the BlogModel's constructor:
Code:
function Blogmodel() {
parent::Model();
}You can set the constructor with __construct() in every controller and model:
Code:
function __construct()
{
parent::__construct();
}But as I said, I doubt this causes the error. The error is in uri right now as you dont seem to get any vars passed to your method and is not actually related to the model itself. Do you use any kind of routes(you forgot to say that)?
You said earlier that its not an htaccess issue. You sure?
What does profiler say without it(remember to set the index.php as index page in the config while testing)?If this problem wont solve, you better do an clean CI install and make a test controller to see that uri works as it should.
