First letter of file name and class name must be in Uppercase.

Your model class will be

class Logon_model extends CI_Model

and the file name will be Logon_model.php

Access it from your contoller like

$this->load->model('Logon_model');

You can give whatever name you want   Styles guides are recommendations and not musts   But you have to care to use everywhere the same name   For example for Test Model you have to   Class Name          class Test Model extends CI Model   File Name          Test Model php   Load Model           this- gt load- gt model  Test Model      Use Model           this- gt Test Model   To avoid using hard coding strings you can load model like this            this- gt load- gt model Test Model  class

In CodeIgniter 3 0-dev  get it from github  this is not working because the CI is search as first letter uppercase   You can find the code on system core Loader php line 282 or bellow    model   ucfirst strtolower  model     foreach   this- gt  ci model paths as  mod path        if     file exists  mod path  models    path  model   php                  continue             require once  mod path  models    path  model   php          CI- gt  name   new  model         this- gt  ci models      name      return  this      This mean that we need to create the file with the following name on application models Logon mode php

Here is what a model should look like  Make sure yours is like this        lt  php     class Logon model extends CI Model        function   construct                  parent    construct               function myFunc                  do something           note the upper-case class name   To load it use    this- gt load- gt model  logon model      note all lower case

Changing the name of model name starting with Uppercase works   Example   Login model php instead of login model php

If you are on Linux then make sure your File name must match with the string passed in the load model methods the first argument    this- gt load- gt model  Order Model   order model      You can use the second argument using that you can call methods from your model and it will work on Linux and windows as well   result    this- gt order model- gt get order details  orderID

When creating models  you need to place the file in application models  and name the file in all lowercase - like logon model php  The logon model php should contain the following    lt  php  if     defined  BASEPATH    exit  No direct script access allowed      class Logon model extends CI Model       public function   construct                 parent    construct                    Now  what you can do  to test if your application model is reachable  is to try opening it in the browser - like so  http   example org application models logon model php  If you see the text No direct script access allowed it means you hit the right file  if you are in doubt  try writing something else in the exit   in the first line    Secondly  for loading the model in your controllers  you should be able to do like this   public function index           this- gt load- gt model  logon model                 If everything above checks out as expected I would begin looking at file permissions and or possibly symlinks if you are using any

I experienced the same problem  but I fixed it by altering my application config routes php file   I made some restructuring to my controller directories and forget to effect it on the routes file   Earlier    route  application apply      ex application account create     and now    route  application apply      application account create

Models must be named and called with the first letter of the model name capitalized and the rest in lowercase    For example   this- gt load- gt model  Logon model     and   class  Logon model  extends  CI Model          But you are correct about the file name

I use codeigniter 3   I had the same problem and in my case I changed model file name starting from uppser case   Logon model php

User · Answer

Change your model file name   start with upper case letter like this  Logon model php  This happens when we migrate our project from windows server to LINUX server because linux is case sensitive while windows is not    So  on windows even if don t write file name with upper case then also it will work fine but not on linux
