undefined function anchor() - davy_yg - 11-04-2014
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?
RE: undefined function anchor() - sv3tli0 - 11-04-2014
Why do you generate url inside the Controller instead inside the View?
RE: undefined function anchor() - InsiteFX - 11-04-2014
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.
RE: undefined function anchor() - Chroma - 11-08-2014
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.
RE: undefined function anchor() - sv3tli0 - 11-08-2014
Small question, why you use HTML helper inside the Controller ?
This is HTML building task and should be done inside your view..
RE: undefined function anchor() - Hobbes - 11-08-2014
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.
