detail page problem, does not exists - El Forum - 06-22-2011

Hi guys I have a little problem with controllers in my project. I am trying to learn Code Igniter as much as possible so I have decided to create a little cms.

However there is a problem in detail page when than it says it does not exists.

Here is my code:

This is my siteview (which is the mainpage view)
Code:
<?php if (isset($games)): foreach ($games as $row) : ?>

<H3> &lt;?php echo $row->title; ?&gt; </H3>

<p> &lt;?php echo $row->text; ?&gt; </p>

<p> &lt;?php echo anchor('detail/'.$row->id,'Read'); ?&gt;

&lt;?php endforeach; ?&gt;

&lt;?php endif; ?&gt;

Of course I have a controller created for this but there is no problem with that.

The problem is with the line

Code:
&lt;?php echo anchor('detail/'.$row->id,'Run'); ?&gt;

when I click on some I get for example:
Code:
http://127.0.0.1:8888/novy/index.php/detail/27
based on the id of each article of course.

So then I have a "detai" controller and inside of it:

Code:
class Detail extends Controller
    {
        function index()
            {
                $data=array();
                // get certain article
                if ($query=$this->detail_model->get_game_db())
                    {
                    $data['games']=$query;    
                    }
                $this->load->view('detail_view',$data);
            }
    }

And then I have a detail_view and inside:

Code:
&lt;?php if (isset($game)): foreach ($game as $row) : ?&gt;

<H3> &lt;?php echo $row->title; ?&gt; </H3>

<p> &lt;?php echo $row->text; ?&gt; </p>

&lt;?php endforeach; ?&gt;
&lt;?php endif; ?&gt;

However when I click on some anchor in site_view I get 404 Page Not Found

The page you requested was not found.

Why is that? it seems everything is right.

Thank you

Michael

The index() method is only called when the only parameter CI has is the controller (or it has no parameter, and determines the controller from the default_controller set in routes.php).

If you want to call the index() method and pass it parameters, you have to explicitly tell CI this:

Code:
&lt;?php echo anchor('detail/index/'.$row->id,'Run'); ?&gt;

Naturally, you probably don't want the /index/ in your URL, which is what routes are for. So, open up config/routes.php and add:

Code:
$route['detail/(:num)'] = 'detail/index/$1';

Voila Smile

Oh thank you it works now. But I still do not get why it has to be like that. Could you please explain it little bit more easier to me? I would like to understand it.

Because I tried to delete detail controller and instead of that I created a function "detail" in the site controller.

so it then was like:

Code:
class Site extends Controller
    {
        
    
        function index()
                {
                $data=array();
                if ($query=$this->site_model->get_games_db())
                {
                    $data['games']=$query;
                }    
                $this->load->view('site_view',$data);
                }

function detail()
            {
                $data=array();
                
                if ($query=$this->detail_model->get_game_db())
                    {
                    $data['games']=$query;    
                    }
                $this->load->view('detail_view',$data);
            }
    }

and then when I had in my site_view this:

Code:
&lt;?php echo anchor('detail/'.$row->id,'Run'); ?&gt;
it worked.


Thank you
