$this->load->model() not working in CodeIgniter

Question

I'm using CodeIgniter 2.1.2 and here's my situation right now. I have a model named math.php in C:\wamp\www\cr8v\application\models. I am trying to load this in my controller from C:\wamp\www\cr8v\application\controllers\site.php yet I am getting this error:

Unable to locate the model you have specified: math_model

Here's the content of math.php:

 <?php
    class Math_model extends CI_Model(){
        public function add(){
            return 1+1;
        }
    }
 ?>

And here's the content of my site.php:

<?php
    class Site extends CI_Controller{
        public function index(){
            $this->addstuff();
        }

        public function addstuff(){
            $this->load->model("math_model");
            echo $this->math->add();
        }
    }  
?>

I followed this in a tutorial in YouTube. Yet, it doesn't give me my desired output. I've tried Googling about it and read other related questions with this, however those information are not enough.

I have read this just a while ago.

Now I have the following error:

( ! ) Parse error: syntax error, unexpected '(', expecting '{' in C:\wamp\www\cr8v\application\models\math_model.php on line 2

The name needs to be the same in all places:

Here:

class Math_model extends CI_Model {
   // your model
}

Here:

$this->load->model("math_model");

When using it:

$this->math_model->add();

And: in your file system. So rename math.php to math_model.php and it will work.

The name of the file should be math_model.php and you should call it like this:

echo $this->math_model->add();

File name and model name should be same try this instead

class Math_model extends CI_Model {
   // your code
}

and the file name should be Math_model.php

This was my issue, specifically I used _Model instead of _model. Thanks. – Thomas Mar 02 '22 at 13:43

The question has been answered really and the problem was this:

 <?php
    class Math_model extends CI_Model(){
        //so on
        } 
 ?>

..it's the open and close parethesis after declaring the class.. it should be:

 <?php
    class Math_model extends CI_Model{
        //so on
        } 
 ?>

thank you so much for those who responded

Well, it should always be noted that function name should not be replicated with controller or model name such as below;

<?php
  class Abc extends CI_Controller{

public function abc(){} // this confused CI in loading   

}

this may be helpful for developers new to CI,
