Here’s my model:

   <?php

   class Dbtest extends CI_Model {

    function __construct()
    {
        // Call the Model constructor
        parent::__construct();
    }


    function getAll() {
        parent::Model();
        $this->db->select('title, content');
        $this->db->from('posts');
        $this->db->where('post_id', 1);

        $q = $this->db->get();

        if($q->num_rows() > 0) {
            foreach ($q->result() as $row) {
                $data[] = $row;
            }
            return $data;
        }
    }
   }

Here’s my controller:

    <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

    class Dbtest extends CI_Controller {

    function index() {
        $this->load->model('dbtest');
        $data['rows'] = $this->dbtest->getAll();

        $this->load->view('dbtest', $data); 
    }
   }

And here’s my view

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

   <html>
      <head>
      <title></title>
       <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    </head>

     <body>
    <div id="container">
        <p>My view has been loaded</p>
        <?php foreach($rows as $r) : ?>

        <h1><?php echo $r->title; ?></h1>
        <div><?php echo $r->content; ?></div>

        <?php endforeach; ?>
        </div>
     </body>
   </html>

I keep getting a 500 server error. What could I possibly be doing wrong. I have autoloaded the database library. Please help a codeigniter newbie trying to learn this great framework.

    function getAll() {
    parent::Model();   //<-------------------Remove this line
    $this->db->select('title, content');
    $this->db->from('posts');

    After taking a quick look, why is this line there?

    It is a php4 constructor call to the old version of the Model base class that no longer exists..

    remove and try again.

    EDIT

    Also, you cannot name a model AND Controller the same name, they have namespace conflicts.

    call the model Dbtest_model or something and use it that way.

    Also, this is unnecessary

        if($q->num_rows() > 0) {
        foreach ($q->result() as $row) {
            $data[] = $row;
        }
        return $data;
    }

    $q->result() returns an array, no need to loop through and rebuild… Just do this…

        if($q->num_rows() > 0) {
        return $q->result();
    }
