$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

Answer 1

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,

Answer 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.

Answer 3

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

Answer 4

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

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

Answer 5

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
