Hi Guys,
i'm a newbie and i've got a problem with the anchor function that doesn't work

here is my code

The controller

Code:
&lt;?php

class Blog extends CI_Controller {

 public function __Blog(){

  parent::__Blog();

  $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);

 }

}

?&gt;

The view

Code:
&lt;html&gt;

&lt;head&gt;

&lt;title&gt;&lt;?=$title?&gt;&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

<h1>&lt;?=$heading?&gt;</h1>

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

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

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

&lt;?php echo anchor('blog/comments','Comments','title="Nuovo commento"');?&gt;

<hr>

&lt;?php endforeach; ?&gt;

&lt;/body&gt;

&lt;/html&gt;

do you find any errors?

Thank you

Lorenzo

Looks like you've loaded the helper, good!

Code:
$this->load->helper('url');

I've just copied the anchor code line in one view I'm working on and the link is created properly.

Strange...

In which folder do you have the helpers?

10-26-2012, 06:19 AM

[eluser]jojo777[/eluser]
Autoload.php

Code:
$autoload['helper'] = array('url');

It seems that the system didn't find the helpers. I've copied them in both application/helpers and system/helpers folders. I've to set a path?

I've never copied helpers in other folder, they are always in system/helpers/

Dis you try a small example? loading a view with a simple anchor!?

Just tried...the browser give me the same error.

Fatal error: Call to undefined function anchor() in C:\xampp\htdocs\codeigniter\application\views\blog_view.php on line 14

I solved replacing

Code:
public function __Blog(){

  parent::__Blog();

  $this->load->helper('form');

  $this->load->helper('url');

 }

with

Code:
public function __construct(){

  parent::__construct();

  $this->load->helper('form');

  $this->load->helper('url');

 }

Someone can explain me the why?

Sorry i didnt realize about the constructor.

Thats the correct way. Is not like Java. Is a built in function.
