Awesome!
Worked perfectly, thank you so much.

Looks like the CI User Guide needs updating. Big Grin

[quote author="LuckyFella73" date="1252182196"]I didn't test this, but maybe this works

Code:
<?php

class Welcome extends Controller {

    function Welcome()
    {
        parent::Controller();    
    }
    
    function index()
    {        
        $data['meta'] = array(
                array('name' => 'robots', 'content' => 'no-cache'),
                array('name' => 'description', 'content' => 'My Great Site'),
                array('name' => 'keywords', 'content' => 'love, passion, intrigue, deception'),
                array('name' => 'robots', 'content' => 'no-cache'),
                array('name' => 'Content-type', 'content' => 'text/html; charset=utf-8', 'type' => 'equiv')
        );
        
        $data['link'] = array(
                  'href' => 'css/printer.css',
                  'rel' => 'stylesheet',
                  'type' => 'text/css',
                  'media' => 'print'
        );
        
        $this->load->view('welcome_message', $data);
    }
}

I can't believe I missed that he was loading the view before assigning the arrays and not even passing the data over....how embarrassing...

Heh, we won't tell anyone. Big Grin

Thank you very much for your help guys. I'm now on the search for a script helper so that I can add script references in the head, but the html helper doesn't seem to offer this. Sad

If you need a solution to load javascripts depending
on the page that is loaded I can tell you what I do
(there may be better ways of course)

I have a config file where I define all needed javascripts - for example:
Code:
$this->js_formscript_news ='<scri+pt type="text/java+scri+pt" src="'.base_url().'js/formscripts_news.js"></scri+pt>';
$this->js_formscript_press ='<scri+pt type="text/java+scri+pt" src="'.base_url().'js/formscripts_press.js"></scri+pt>';
// and so on

In the contructor of my controller I load the config file
Code:
$this->load->file('system/application/config/config_admin.php', true); // for example

In the different functions (before calling the view files I
set the needed js in case I need one or more like this:
Code:
$data['js_import'] = array ($this->js_formscript_news,$this->js_formscript_press);

And at last in view file (header part of course) I have this:
Code:
&lt;?php
if ( isset( $js_import ) AND count( $js_import ) > 0 )
{
    foreach ($js_import AS $js_data)
    {
        echo $js_data;
    }
}
?&gt;

If somebody has a better solution I would be really interested in!
