I'm getting an unable to locate model error.
$this->load->model('1/Gift_model');
My model file name is gift_model.php within /models/1/.
I declare the model the following way.
class Gift_model extends CI_Model {
According to CodeIgniter's documentation I'm doing it the correct way. Any suggestions? I have 5 other models named exactly the same way and they're all loading fine.
Make the model class name Uppercase My_model
Make the model php file name Lowercase my_model
Load the model using Lowercase (file name) $this->load->model('my_model');
$this->load->model('1/Gift_model'); should be $this->load->model('1/gift_model');. Lowercase on this load argument and the php filename, uppercase on the class name within the file (you had two of three correct).
http://www.codeigniter.com/userguide3/installation/upgrade_300.html
Starting with CodeIgniter 3.0, all class filenames (libraries, drivers, controllers and models) must be named in a Ucfirst-like manner or in other words - they must start with a capital letter.
Used to be the model files started with lower case, but they changed it.
Ensure that the the model name is Gift_model and the class name is also Gift_model
class Gift_model extends CI_Model
{
}
but loading the class is '1/gift_model' NOT 'Gift_model'
$this->load->model('1/gift_model');
hope this was helpful
The problem is that your file name is all lowercase (gift_model.php) while you are loading Gift_model within CodeIgniter. Either change the file name to Gift_model.php or update your code accordingly.
Are you calling the parent's constructor for the model?
class Gift_model extends CI_Model {
function __construct()
{
parent::__construct();
}
-> Model Class name must be Uppercase
-> Model PHP file name must be Lowercase
-> Load Model using Lowercase(filename): $this->load->model('gift_model', TRUE);
Starting with CodeIgniter 3.0, all class filenames (libraries, drivers, controllers and models) must be named in a Ucfirst-like manner or in other words - they must start with a capital letter.

`if using codeignitor 3.1.3
every thing same otherwise showing error
class name => My_model
file name => My_model.php
load model => $this->load->model('My_model');
call function => $this->My_model->function();`

After Hosting Php codeignitor website I Got a Error "Unable to locate the model you have specified: Common_model"
But Its Works in my local server
How I can solve this issue
I already change First letter of the model class name capitalized but no result
my model class
class Common_model extends CI_Model
{
}
and controller is
<?php
class Show extends CI_Controller
{ var $pageLimit = 6;
public function __construct()
{
parent::__construct();
$this->load->library('ion_auth');
$this->load->model('common/Common_model');
$this->load->helper('url');
$this->load->helper('form');
$this->load->helper('custom');
}
}
If you are are using Codeignitor 3 than make sure you file name also start with capital letter as:
Common_model.php
It's recommended to use your models inside the model folder not model/anyfolder
Codeignitor 3 Change Log User Manual
I hope Your model file structure is like
application
model
common
Common_model.php
File name should be Common_model.php.
Load in Controller should be
$this->load->model('common_model');
I always load it with the name only, this way
$this->load->model('Common_model');
Always the controller is on the same module (if you are using modules)
Everytime the controller tries to access home model, It displays
Unable to locate the model you have specified: HomeModel
error.
The controller has no problem in accessing view.
And it was able to access the model class after I changes the model name to lowercase. Can somebody explain why this happens?
When creating a model on codeigniter
classes and file names should have there first letter as upper case this also applies for controllers and libraries etc.
Home_model.php
class Home_model extends CI_Model {
public function __construct() {
parent::__construct();
}
public function some_function() {
}
}
How to load model on controller example only
class Welcome extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('home_model');
// Or In a subfolder application / models / subfoldername
$this->load->model('subfoldername/home_model');
}
public function index() {
$data['results'] = $this->home_model->some_function();
$this->load->view('welcome_message', $data)
}
}

URLs
Your URLs should typically be all lowercase letters. If you expect capital letters, there's a chance you could accidentally exclude their lowercase counterparts, even though they're the same URL. Example: www.example.com/controller/method/param
Controllers
Controller class names should be all lowercase, except the first letter.
If your URL is www.example.com/gallery, the controller name is Gallery.
If your URL is www.example.com/admin_folder, the controller name is Admin_folder.
Controller file names should match the class name, but be all lowercase.
Gallery :: gallery.php
Admin_folder :: admin_folder.php
Controller methods should be all lowercase as well. There is some flexibility with uppercase, but similar to URLs, there are opportunities where it can goof something up (here's an example where capital letters interfered with a form validation callback method).
Models
Models follow most of the same conventions as controllers. The only difference is with model method names, which can use your preference of capitalization. Since these methods are not tied to URLs, and are called using normal PHP OOP, you can name them as you please.
It is recommended to load models using the all lowercase version. While it is not required by CI, it can confuse some users if they load it with a capital letter, but then attempt to access it as all lowercase (this is due to native PHP being case sensitive with class properties [and variables in general], not CodeIgniter).
Model class name: Users_model (the _model suffix is also not required, but some people may use it as a personal preference, or to prevent naming conflicts with a Users controller).
Model file name: users_model.php
Model loading: $this->load->model('users_model')
Model method names (all okay): $this->users->getAll(), $this->users->find_by_name($name), etc.
Libraries
Libraries follow the same conventions except for the file name. In their case, file names should match the class name.
Similar to models, it's recommended to load libraries using the lowercase name.
These rules are the same for CI's libraries (located in application/core and application/libraries, as well as custom or third-party libraries.
Special note: when extending default CI libraries, the prefix as defined in application/config.php comes into play. This prefix typically should be all uppercase, followed by an underscore. The default is MY_.
Library class name: Photos
Library file name: Photos.php,
Library load: $this->load->library('photos')
Helpers
Helper names and loading are all lowercase. The filename consists of the helper name with _helper appended after.
Helper name: url
Helper file name: url_helper.php
Helper load: $this->load->helper('url')
Notes
CodeIgniter is somewhat inconsistent in their naming conventions, but there really aren't too many rules, so they are easy to get used to and memorize. I very rarely have issues with naming and loading in CI, and when I do, it's usually because I was just working on a Composer-related project so I got into a different habit.
The rules in this answer are for CodeIgniter 2.1.x as of this writing. There is discussion on Github for 3.0 to better and add more consistency to naming conventions, which you can read about and contribute to if you'd like.
In my CI 2.2 project I want to make my parent controll with app's common functionality for use in all app and for this I create file :
application/libraries/N_Controller.php :
<?php
class N_Controller extends Controller
{
public function __construct()
{
parent::__construct();
}
But on first attempt to use it in file
application/controllers/admin/admin.php
<?php
class Admin extends N_Controller
{
public function __construct()
{
parent::__construct();
I got error:
PHP Fatal error: Class 'N_Controller' not found in /controllers/admin/admin.php on line 3, referer: http://local-ci22.com/admin/hostel/edit/15
I tried to add in application/config/autoload.php file :
$autoload['libraries'] = array( 'AppSmarty', 'AppUtils', 'N_Controller');
But it did not help. Which is the correct way ?
if you want to extend the functionality of a system class. you need to follow this recomendations.
place your extended class in /application/core, be sure that you name it exactly like the name and casing of the class created.
your class should extend from CI_Model or CI_Controller, depending on your needs.
wherever you implement your new class, be sure that you honor the same name casing from your extended class.
you should have configured the $config['subclass_prefix'] on /application/config/config.php. let's say in your case with the value 'N_'
what i can see from your code, you are not extending from CI_Controller and your path seems wrong.
Informative note: the /application/library is used to place classes and libraries from 3rd parties that won't fit into CI schemas.
Very frustrating -
When I'm developing locally everything works perfect . I then started testing on my host (GoDaddy) for the first time and I get the error
Fatal error: Class 'MY_Model' not found in /home/content/49/12220009/html/application/models/user_model.php on line 3
The code is very basic -
User_model.php
class User_model extends MY_Model {
protected $_table;
public function __construct() {
parent::__construct();
$this->_table = "user";
}
MY_Model.php (application/core/My_Model.php)
class MY_Model extends CI_Model
{
public function __construct() {
echo "in my model ctor";
parent::__construct();
}
And it all starts with a controller loading User_model as expected -
$this->load->model('user_model');
Any thoughts on why this would work locally but not on my host , or how to solve it in other words?
it is definitely a case-sensitivity issue; what you should do is follow these two steps
1.follow these conventions and you are good to go
class Model_name extends CI_Model
Model_name is the name of your class... Class names must have the first letter capitalized with the rest of the name lowercase
and then the file name should be in lower case like this
application/models/model_name.php
This also happened to me:
on Linux system ,it show the error you specify while on window it was fine.
this is because Linux is case sensitivity .
what i did?;
I rename the file from /core/MY_model to /core/MY_Model.
and ,then it solved my problem .
CodeIgniter 3 solution
The class name and the class filename must have an uppercase first character.
Starting with CodeIgniter 3.0, all class filenames (libraries,
drivers, controllers and models) must be named in a Ucfirst-like
manner or in other words - they must start with a capital letter.
For example, if you have the following library file:
application/libraries/mylibrary.php
… then you’ll have to rename it to:
application/libraries/Mylibrary.php
I'm trying to call a library from model in codeigniter but doesn't want to fire and I don't really know how to debug it, I have been trying to use codeigniters default logging method but doesn't show anything. My code looks as it follows.
class Model_products extends CI_Model{
function __construct(){
parent::__construct();
$this->load->library('ApiClient');
log_message('error', $this->load->library('ApiClient'));
}
}
/application/libraries/ApiClient.php
libary final class ApiClient
{}
You cannot name a library ApiClient - class names should follow the CI naming convention (which is identical to ucfirst()) and when loading anything in CI you need to load it with lowercase naming.
Naming is the key.
Your file should be named Apiclient.php (libraries has the first letter in uppercase in the filenames, models, views and controller are all lowercase filenaming).
Your class definition should reflect this also:
class Apiclient
{
...
}
And when using the CI instance to load the library, you need to load it with lowercase naming:
$this->load->library('apiclient');
You miss a semicolon at the end of your line $this->load->library('ApiClient'). Could this be it?
