How to redirect http to https in codeigniter

Please Check this may help

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

$config['enable_hooks'] = TRUE;

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'                                );

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());    }}

I tried above all ones but they did not work properly in my case. I found below solution, it works in my case. I hope it will be helpful for you as well.

RewriteEngine onRewriteCond %{HTTPS} offRewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]RewriteCond $1 !^(index\.php|resources|robots\.txt|public)RewriteCond %{REQUEST_FILENAME} !-fRewriteCond %{REQUEST_FILENAME} !-dRewriteRule ^(.*)$ index.php?/$1 [QSA,L]

Now I got a solution,I updated my htaccess file.--

RewriteEngine OnRewriteCond %{HTTPS} off [OR]RewriteCond %{HTTP_HOST} !^www\. [OR]RewriteCond %{HTTP_HOST} ^myhost\.com$ [NC]RewriteRule ^ https://www.myhost.com%{REQUEST_URI} [R=301,L,NE]RewriteCond %{THE_REQUEST} ^[A-Z]+\ /index\.php(/[^\ ]*)?\ HTTP/ RewriteRule ^index\.php(/(.*))?$ myhost.com/$2 [R=301,L]RewriteCond %{REQUEST_FILENAME} !-fRewriteCond %{REQUEST_FILENAME} !-dRewriteRule ^(.*)$ index.php/$1 [L]

Now, It worked for me smoothly.. :)
