captcha in php codeigniter showing fatal error

i am completely new to codeigniter, i have created a captcha using an online tutorial for my login form in codeigniter. i get the following error while loading my login page:

> Fatal error: Call to undefined function base_url() in

    $config = array(
        'img_path'      => 'captcha_images/',
        'img_url'       => base_url().'captcha_images/',
        'img_width'     => '150',
        'img_height'    => 50,
        'word_length'   => 8,
        'font_size'     => 16
    );
    $captcha = create_captcha($config);

i dont have any folder named 'captcha_images', all i have is a controller for captcha,config and the view in login. As am new to this, is it because i dont have a folder or i didnt call any library? please help me with this. thanks in advance

Go to application/config/autoload.php Write this line below (You will find codeigniter nice documentation at line 90) $autoload['helper'] = array('url');

This will autoload url helper. base_url() function is defined in url helper

You can manually load this for a particular controller

Wrire this line $this->load->helper('url'); Within controller constructor or

Controller action function

For more information about base_url click
