Hi
Need help please. Have sat two days trying to get this seemingly simple code to run but not happening. Will post my model, controller and view; if you can see an error in the code please let me know. Thank you very much.

url =
Code:
http://localhost/CodeIgniter1.7.2/topic

model
Code:
<?php
    class Mtopic extends Model {

    function Mtopic() {
        parent::Model();
    }

    function get_records() {
        $q = this->db->get('tbltopic');
        return $q->result();
        }
    }
?>


controller
Code:
<?php
    class Topic extends Controller {

    function index()
    {
        $this->load->model('mtopic');
        $data['result'] = $this->mtopic->get_records();
        $this->load->view('topic_view', $data);
    }
}
?>


view
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    &lt;html &gt;

&lt;head&gt;
  &lt;title&gt;Topics&lt;/title&gt;
&lt;/head&gt;

&lt;body&gt;


&lt;?php
    foreach($result() as $row)
    {
      echo $row->Topic  . "<br />";
    }
?&gt;

&lt;/body&gt;
&lt;/html&gt;

I'm unfamiliar with the error 'not happening' - perhaps you could use more words to describe what happens.

Controllers like a constructor, too.

Unrelated to your problem - the manual indicates you should load models using their ucfirst() name (not just lower case as you've done here) and subsequently refer to them with their ucfirst() name too.

Enable error reporting in your php.ini or use ini_set() to show errors while you're in development. I believe stormlead already answered your question however Wink

There is two mistaken you have done.
1. In model function, you forget to use $ sign.

here is ur code
Code:
function get_records() {
        $q = this->db->get('tbltopic');
        return $q->result();
        }
    }

--&gt; Correct it like this
Code:
function get_records() {
        $q = $this->db->get('tbltopic');
        return $q->result();
        }
    }

2. In the view file, the argument in foreach loop.
here is ur code
Code:
&lt;?php
    foreach($result() as $row) // should not be $result()
    {
      echo $row->Topic  . "<br />";
    }
?&gt;

--&gt; It should be like this
Code:
&lt;?php
    foreach($result as $row)
    {
      echo $row->Topic  . "<br />";
    }
?&gt;

Yes that's it, two errors. I just could not see them.
About the result() error I guess I turned it into function, instead of a key from the $data array. Think I'm getting it slowly. Thanks very much for all the feedback.
