Hello everyone.
I am doing the 20-min-blog tutorial and I am stuck on url helper anchor function.
When I load the page with this

Code:
&lt;?php foreach ($query->result() as $row):?&gt;

<h3>&lt;?= $row->title ?&gt;</h3>

<p>&lt;?= $row->body ?&gt;</p>

<p>&lt;?= anchor('blog/comments', 'Comments'); ?&gt;</p>

<hr>

&lt;?php endforeach;?&gt;

it breaks at anchor. The html source is

Code:
&lt;html&gt;

&lt;head&gt;

&lt;title&gt;My Blog Title&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

<h1>My Blog Heading</h1>

<h3>My first entry</h3>

<p>haha aha a ha</p>

<p>

I go to php error logs and it sais.

PHP Fatal error: Call to undefined function anchor() in C:\Users\****\ZendServerCE\Apache2\htdocs\codeIgniter\Invent\system\application\views\blog_view.php on line 12

Im using ZendServerCE.

Anyone know what might be the problem here?

Are you loading the URL helper: http://ellislab.com/codeigniter/user-gui...elper.html

Yes, my blog.php looks like:

<?php
class Blog extends Controller{
function index(){

function Blog(){
parent::Controller();

$this->load->helper('url');
$this->load->helper('form');
}

$data['title'] = "My Blog Title";
$data['heading'] = "My Blog Heading";
$data['query'] = $this->db->get('entries');

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

You need to move your constructor outside of the index method:

Code:
&lt;?php

class Blog extends Controller{

  function Blog(){

      parent::Controller();

      $this->load->helper(‘url’);

      $this->load->helper(‘form’);

  }

  function index(){

      $data[‘title’] = “My Blog Title”;

      $data[‘heading’] = “My Blog Heading”;

      $data[‘query’] = $this->db->get(‘entries’);

      $this->load->view(‘blog_view’, $data);

  }

}

Your constructor shouldnt be inside your index function. Try this:

<?php
class Blog extends Controller{
  function index(){
   $this->load->helper(‘url’);
   $this->load->helper(‘form’);

   $data[‘title’] = “My Blog Title”;
   $data[‘heading’] = “My Blog Heading”;
   $data[‘query’] = $this->db->get(‘entries’);

   $this->load->view(‘blog_view’, $data);
  }
}
?>

You may want to consider adding the url and form helpers to your autoloader: http://ellislab.com/codeigniter/user-gui...oader.html

Thank you guys, it works now. That video tutorial is misleading, they should review it.

Glad we could help. I remember working off of those video tutorials almost a year ago, and then they were outdated. I'm sure by now (and with CI2 looming) they're way out of date. They're a good start. There's some other sites that have more recent video (and text) tutorials.
