Question

I’m a complete beginner in CodeIgniter. I’m trying to understand the MVC pattern,which is getting a bit trickier as I’m going ahead with CodeIgniter.
This is what my Controller looks like i.e hello.php :

<?php
    class hello extends CI_Controller
    {
        var $name;
        var $color; 
        function hello()
        {
            parent::Controller();
            $this->name  ='Leroy';
            $this->color ='red';
        }

        function show()
        {   
            $data['name'] =$this->name;
            $data['color']=$this->color;    
            $this->load->view('show_message',$data);
        }
    }
?>

the view i.e show_message.php

<p align="center">Hello <font color="<?=$color?>"><?=$name?></font>..!!!!.</p>

when I run this script it gives this error

Fatal error: Call to undefined method CI_Controller::Controller() in C:\xampp\htdocs\CodeIgniter\application\controllers\hello.php on line 8

P.S I’m using CodeIgniter version 2.0 so I changed the class name to CI_Controller

Answer 1

function hello()
    {
        parent::Controller();
        $this->name  ='Leroy';
        $this->color ='red';
    }

Replace your constructor code with this

    function __construct()
    {
        parent::__construct();
        $this->name  ='Leroy';
        $this->color ='red';
    }
