I am using the CodeIgniter framework for PHP. I have created a view named "login.php". Once I

created the view, I then loaded the view inside of a function named "index" which is located

inside a class named "CCI" that extends the Controller but I keep receiving this error: Fatal

error: Call to undefined function site_url() in C:wampwwwFinalP_CCI_Clonesystem

applicationviewslogin.php on line 12. I don't understand the issue I an having because the

welcome page loads fine and my second function inside of the "CCI" class loads fine as well.

Here is some of the code:

Controller Files:

function CCI()

 parent::Controller();


function index()

 $this->load->view('login');


function test()

 echo "Testing Data";

}

/* End of file login.php /
/ Location: ./system/application/controllers/cci.php */

class Welcome extends Controller

function Welcome()

 parent::Controller(); 


function index()

 $this->load->view('welcome_message');


function test()

 echo "Testing Data";

/* End of file welcome.php /
/ Location: ./system/application/controllers/welcome.php */

You have to load the helper. The function site_url() is provided by the url helper, as described here.

$this->load->helper('url');

You can try this:

1. 
   

   First Load the URL Helper with:

   
   
   
   • 
     $this->load->helper('url'); or set the following value in application/config/autoload.php
     
   
   
   • $autoload['helper'] = array('url');
   
   


2. Then you can show the site url with:
   
   
   • 
     base_url() (result: http://example.com/) or
   
   
   • 
     site_url() (result: http://example.com/index.php/)
   
   

Note: Results depends on values stored in application/config/config.php
