I am using codeigniter 2 and I have my theme folder consist of js, img, css folders.

Inside js folder, file name is js_functions.php contains:

<?php header("Content-type: text/javascript"); ?>
/**
 * GLOBAL VARIABLES & PATHS
 *
 * path definitions for jquery inline usage
 *
 */     
var base_url         = '<?=base_url();?>';
// ------------------------------------------------------------------------

/**
 * jquery.message Global Implementation
 *
 * Shows message if any session flashdata named message is set
 *
 */

<?php if($this->session->flashdata('message')):?>
$(function() { $().message("<?=$this->session->flashdata('message');?>"); });
<?php endif; ?>

// ------------------------------------------------------------------------

and, calling in it view file

<script type="text/javascript" src="<?=base_url();?>themes/admin/js/js_functions.php"></script>

renders correctly. But it returns in the chrome's inspect screen: 

var base_url         = '<br />
Uncaught SyntaxError: Unexpected token ILLEGAL

and in the browser when you call the page from address bar:

var base_url         = '<br />
<b>Fatal error</b>:  Call to undefined function base_url() in <b>F:\xampp\htdocs\themes\js\js_functions.php</b> on line <b>11</b><br />

What's wrong? Isn't it the correct way of using php in external js/php file?

  • Is js_functions.php a standalone file, or does it include other files? If it's standalone, how does it know what base_url() is? Commented Apr 11, 2012 at 15:02
  • @TRiG it doesn't include any file. I think it is the question you mentioned: How can it make know that it is working in codeigniter? Commented Apr 11, 2012 at 15:05
  • Well, that's your problem, but I'm not familiar enough with CodeIgnitor to know how to fix it. What do you expect $this to be in the context of this script? Commented Apr 11, 2012 at 15:06

You need to make a controller to get the script. May be js. Inside your controller you set the content type headers and load the view which contains above javascript. Lets say you have a controller called js

class Js extends CI_Controller{
  public function js_functions(){
    $this->output->set_header('Content-type: text/javascript');
    $data = array( 'messages' => $this->session->flashdata('message'));
    $this->load->view('jsfunc',$data);
  }
}

And you can load the script in the main view like this

<script src="<?php echo base_url('js/js_functions'); ?>"></script>

If you want to generate dynamic js, css files. Use standart MVC method. Make a folder in view folder with name js or css. Create js or css files as php view file. For example : slider.js.php.

Make a controller themejs.php. Forward all js or css files to this controller which you need, by using routing. And inside this controller make dynamic action, pass varibles to js, css view files. And print them with header

base_url() is a function part of the CI url helper. If you want to make use of it in that file and you don't want to create an instance of the $CI object, you will have to implement your own version of that function.

helpmed to identify the real problem, thank you.
You can also have a look at embedding assetic(github.com/kriswallsmith/assetic) into your application. With that combined with the custom controller solution above, you'll manage assets in style.
