I need to create a few dynamic javascript files that contains information from the db. What would be the correct way to do this with codeigniter. Normally I would create a javascript.php file with javascript headers and grab the information directly from the database.

You can do the same with Codeigniter. Just create a function inside a controller and link to it as you would a .php file.

Alternatively, you can create a function which actually writes the javascript to a .js file and reference that.

Code:
&lt;head&gt;

 <s-c-ri-p-t>

  //These variables will be available in external files (including functions)

  var SITE_BASE_URL = "&lt;?php echo base_url()?&gt;";

  var SITE_TIME = &lt;?php echo time()>;

 </s-c-ri-p-t>

 <s-c-r-i-pt s-rc="external-file-process-time.js" ></s-cr-i-p-t>

&lt;/head&gt;

I'm trying to do this and Actually works but I get the following error "Cannot modify header information - headers already sent by ...system/core/Output.php 276".

What could be wrong in the following code in the controller function (/site/lang_js)?

[code]
function lang_js() {

$this->output->set_header('Cache-Control: no-cache, must-revalidate');
$this->output->set_header('Exprires: Mon, 4 April 1994 04:44:44 GMT');
$this->output->set_header('Content-type: application/x-javascript');

$this->lang->load('messages',$this->session->userdata('language'));
$this->lang->load('user',$this->session->userdata('language'));

echo "var lang = " . json_encode($this->lang->language);

}
[code]

Thanks!

don't echo
do

Code:
$this->output->set_output("var lang = " . json_encode($this->lang->language));

Although when I want to serve a js file I usually do

Code:
header('Content-Type: text/javascript; charset=UTF-8'); 

echo $output;
