Question

i have written a small codeigniter test app that is currently running on my windows box.
i created a linux vm and have tried to install the app on this new virtual server.
some of my web app is running properly but other parts, no.
specifically, this works:

 http://123.123.123.123/myapp/controller1/

but this does not:

 http://123.123.123.123/myapp/controller2/mymethod/1/2/3

It fails with an error that it can’t load controller2_model.

Here’s the actual code for the controller that is failing (it’s really called xferLogger vs. controller2):

 class xferLogger extends CI_Controller { 
      public function __construct() { 
              parent::__construct();
              echo(2); 
              $this->load->model('xferLogger_model'); 
              $this->load->helper('date'); //this library is needed for the base_url() method that is being called in the view "result.php" 
              $this->load->helper('url'); 
      } 

and here’s the model:

class xferLogger_model extends CI_Model { 
    public function __construct() { 
              $this->load->database();
                } 

The full error message is: An error was encountered. Unable to locate the model you have specified: xferlogger_model.

Here’s something I noticed. in the error message, you’ll notice that the “L” in logger is lowercase. but in my code, it’s a capital L.
I’ve checked in my controller, the model itself, and also the routes.php file. I can’t seem to find any problems with my casing.

Answer 1

From the userguide: Class names must have the first letter capitalized with the rest of the name lowercase. So therefore:

class Xferlogger_model extends CI_Model // First letter capitalised

and your model load

$this->load->model('xferlogger_model');  // lower case

and your PHP filename

xferlogger_model.php    // lower case
