致命错误：在codeigniter中找不到类

Question

I have created a model Admin_Model under Application\core directory of code igniter. I put all basic database operations under it. When I try to extend my models who are under Application\model directory, it throws error.

Fatal error: Class 'Admin_Model' not found in <path to root>/application/models/new_model.php on line 3

Should I miss any configuration?

Answer 1

Thanks all for your efforts. I find a solution.

By default CodeIgniter have a setting in its config file.

$config['subclass_prefix'] = 'MY_';

I just replace 'MY_' with 'Admin_' everything works fine.

$config['subclass_prefix'] = 'Admin_';

More appropriate solution is

1. Put class file in libraries folder

2. Add following code to config.php

   function __autoload($classname)
   {
   if(strpos($classname,'CI_') == 0)
   {
       $file = APPPATH.'libraries/'.$classname.'.php';
       if(file_exists($file))
       {
           @include_once($file);
       }
   }
   }
   

That's All
