I looked up the topics around, but I didn't see something for my case.
So, I have controller filled up with methods, and a construcor which loads the models that i commonly use in this specific controller. Everything works fine. I needed to set an array in the constructor like

$data["content"]["something"] = "bla bla";

Thats all. So I pass the $data["content"] to the view loader, and I'm expecting to have access to 

$something

, but no. It takes it as undefined variable, but why? When I put it in the specific method everything works fine, but when it is in the constructor it says undefined. Any ideas? Thank you! :)

You cannot access constructor variables in View. You need to pass it to controller's method and pass it to view. For example,

In Constructor :

$data["content"]["something"] = "bla bla";

In Controller's Method :

$data['something'] = $this->$data["content"]["something"];

Now you can pass $data to view and access like echo $something;

So. i missed that. but still learning ^^ i hope Paul has something about this. –  Kees Sonnema Apr 5 '13 at 8:12
    
Hmm, nope, but thanks. :) public function __construct(){ parent::__construct(); $section = "bla bla"; } public function index(){ $data["content"]["section"] = $this->$section; $this->load->view("view", $data["content"]); } Now it says that the variable is empty, strange. –  Paul Reed Apr 5 '13 at 8:27
    
@PaulReed How you are displaying in View? –  Edwin Alex Apr 5 '13 at 8:30
    
I'm passing on $data["content"], so in the view I access $section. But the error is here $data["content"]["section"] = $this->$section; CodeIgniter says that $this->$section is empty property. –  Paul Reed Apr 5 '13 at 8:33
    
Solved. I made it object. $this->section = "bla bla" and in the controller $data["content"]["section"] = $this->section. –  Paul Reed Apr 5 '13 at 8:56

It seems as though you are not understanding variable scope on this issue. Instead of creatnig a local variable $data try using $this->data which will be available to the entire object (controller)

function __construct() {
    ...
    $this->data['content'] = array('test' => 'test');
    ...
}

You can then also pass it to the view using the variable $this->data too, and append/modify it at any time during execution.

$this->load->view('path/to/view', $this->data);

You have to do:

$data["content"] = "bla bla";
$data["something"] = "bla bla";

$this->load->view('path/to/view', $data);

that way you have all the data strings in your views.

<?php echo $something; ?>

<?php echo $content; ?>

it's not a good idea to pass 2 variables in one $data string.

Sure, but I want to pass all the $data["content"] to the view. This is the reason that I use multi-dimentional arrays. In the current case I actually set $data["content"]["section"], $data["content"]["manufacturers"]. So I send $data["content"] the view and I can access $section and $manufacturers. –  Paul Reed Apr 5 '13 at 8:06
    
i think the best way is to call all the functions a part. and just put $this->load->view('path/to/view', $data); so you jsut have all the data strings in your views. –  Kees Sonnema Apr 5 '13 at 8:09
    
The situation is this: I have two almost identical controllers, but I use them with different models, and they use different data. Since they are almost identical I use same views for both controllers, I have some forms in there, and to specify the form url I want to pass a variable which defines it. –  Paul Reed Apr 5 '13 at 8:17
    
I'm already passing data to the view, this isnt the case. The idea is that I don't want to write $data["content"]["section"] in every method, I just want to set it in the constructor and every method to get it automaticly. –  Paul Reed Apr 5 '13 at 8:20
    
see the other answer from Edwin. i think that's worth a try. –  Kees Sonnema Apr 5 '13 at 8:20
