How to Simplify Header and Footer Inclusion in CodeIgniter?

Simplifying Header and Footer Inclusion in CodeIgniter

Programmers often find it tedious to manually load header and footer views in every controller. This becomes even more problematic when changes need to be made to these common elements across the application. Here's a solution that automates this process:

In CodeIgniter's core/MY_Loader.php file, create an extension of the CI_Loader class:

<code class="php">class MY_Loader extends CI_Loader {
    public function template($template_name, $vars = array(), $return = FALSE)
    {
        $content  = $this->view('templates/header', $vars, $return);
        $content .= $this->view($template_name, $vars, $return);
        $content .= $this->view('templates/footer', $vars, $return);

        if ($return) {
            return $content;
        }
    }
}</code>
Copy after login

Alternatively, for CodeIgniter 3.x, the following code can be used:

<code class="php">class MY_Loader extends CI_Loader {
    public function template($template_name, $vars = array(), $return = FALSE)
    {
        if ($return):
        $content  = $this->view('templates/header', $vars, $return);
        $content .= $this->view($template_name, $vars, $return);
        $content .= $this->view('templates/footer', $vars, $return);

        return $content;
    else:
        $this->view('templates/header', $vars);
        $this->view($template_name, $vars);
        $this->view('templates/footer', $vars);
    endif;
    }
}</code>
Copy after login

In your controller, you can now use the template() function like this:

<code class="php">$this->load->template('body');</code>
Copy after login

This method automates the inclusion of the header and footer views, making it much easier to update and maintain your application's layout.
