How to Streamline Header and Footer Management in CodeIgniter?

Header and Footer Management in CodeIgniter

CodeIgniter, an MVC-based PHP framework, provides flexibility in managing page sections like headers and footers. It allows developers to customize these sections based on specific requirements. However, manually loading individual header and footer views in each controller can be repetitive and time-consuming.

Solution: Customizing the Loader

To streamline this process, CodeIgniter offers a mechanism for creating custom loaders. By extending the built-in CI_Loader class, developers can modify its functionality and avoid redundant code. This enables the automated inclusion of headers and footers in all pages where desired.

CodeIgniter 2.X:

Create a new file in the "/application/core" directory named "MY_Loader.php":

<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>

CodeIgniter 3.X:

For CodeIgniter 3.X, the same approach can be used with a slight modification:

<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>

Using the Custom Loader:

In a controller, loading the header and footer becomes as simple as:

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

This automatically includes the "header" and "footer" views in the main "body" view. Any changes made to these templates will be reflected in all pages that use the custom loader.
