Fatal error: Call to undefined function anchor() in C:\xampp\htdocs\CI202-CRUD\application\controllers\welcome.php on line 13

controllers/welcome.php

PHP Code:

class Welcome extends CI_Controller {
    function __construct()
    {
    //    parent::__construct();
    //    $this->load->helper(array('html','form', 'url'));
    }
    public function index()
    {
        $data = array(
            'title' => 'Welcome Profile Edit',
            'body' => anchor(base_url().'member_area/', 'Member area')
        );
        $this->load->view('_output_html', $data);
    } 


I already autoload the helper:

autoload.php

PHP Code:

$autoload['helper'] = array('html','url','form'); 


I wonder how to fix the error?

Why do you generate url inside the Controller instead inside the View?

[InsiteFX]

If you must do it from code you can do it like below. But sv3tli0 is correct it should be done in your html.

Code:

$out = '<li>' . anchor($categories[$i]['link'], $categories[$i]['title']) . '</li>';

$data = array(
    'body' => $out,
);

You cannot place php code inside php code like that, that's why the error.

@Narf: I meant inside an associated array, it just does not like it! But works fine this way.

Yes you can.

i have had the same experience as InsiteFX

going :

$data = array(
'body' => anchor($categories[$i]['link'], $categories[$i]['title'])
);

always seems to not work at all or throws an error. but putting it like InsiteFX stated works just fine

Nonsense.

@davy_yg's issue is that he's overriding CI_Controller::__construct(), but not calling parent::__construct() in the override. The constructor is what triggers the autoloader.

If using base_url(), I find it much easier to place the additional URL path inside the () or the function.

base_url('path/to/item')

rather than spread it out, makes the code easier too.

In full agreement, you must uncomment the call to the controllers parent.

[sv3tli0]

Small question, why you use HTML helper inside the Controller ?
This is HTML building task and should be done inside your view..

[Hobbes]

i was just sayin' that when I use any of the html helper functions, I half to put them in a variable before putting them into an array or else like I said, it either does not work or throws an error.
