Redirect to ssl in codeigniter

Redirect to ssl in codeigniter :-

HTTPS :- Full name is (hyper text transfer protocol secure). It’s a extended or you can say secure version of the HTTP(hyper text transfer protocol). If you have https enabled on your server you will get a lock icon in address bar of browser.
For encryption of data it’s used SSL(secure sockets layer) certificates to install on your server. Most uses of https to securely transmit data with ssl.
So most of sites need ssl or https url. we can easily manage redirection to https url in codeigniter using hooks. it’s a one more good feature of CI. We need to create some lines of code to get ssl url or redirect to https url in codeigniter. Default codeigniter not have this type of functionality so we need to force redirect to ssl url. below we will see how to use ssl redirect with codeigniter.

1. Config changes :- Go to “application/config/config.php” and enable or set hooks to true.

	
$config['enable_hooks'] = TRUE;

2. create a new file named hooks.php in “application/config/hooks.php” and add below code in hooks.php:-

$hook['post_controller_constructor'][] = array(
                                'function' => 'redirect_ssl',
                                'filename' => 'ssl.php',
                                'filepath' => 'hooks'
                                );

3. Now create a new directory with named “hooks” under application directory and then create new file named “ssl.php” in “application/hooks/ssl.php”
and add below code to “ssl.php” :-

function redirect_ssl() {
    $CI =& get_instance();
    $class = $CI->router->fetch_class();
    $exclude =  array('client');  // add more controller name to exclude ssl.
    if(!in_array($class,$exclude)) {
      // redirecting to ssl.
      $CI->config->config['base_url'] = str_replace('http://', 'https://', $CI->config->config['base_url']);
      if ($_SERVER['SERVER_PORT'] != 443) redirect($CI->uri->uri_string());
    }
    else {
      // redirecting with no ssl.
      $CI->config->config['base_url'] = str_replace('https://', 'http://', $CI->config->config['base_url']);
      if ($_SERVER['SERVER_PORT'] == 443) redirect($CI->uri->uri_string());
    }
}

Now check your site you will get https in url. redirect to https url in codeigniter using hooks is a good method rather than htaccess.
