How can I have CodeIgniter load specific pages using SSL?

Question

How can I have CodeIgniter load specific pages using SSL? I have an apache2/mode_ssl server. mod_ssl uses a different document root than non-secure

Answer 1

I would maintain two sets of the code and handle a forced redirect to HTTPS pages with a post_controller_constructor hook. The hook will be called before each page is rendered to check if the visitor should be redirected to HTTPS based on their current location on your site.

STEP 1

Create file: system/application/hooks/SecureAccount.php

<?php

class SecureAccount
{
    var $obj;

    //--------------------------------------------------
    //SecureAccount constructor
    function SecureAccount()
    {
        $this->obj =& get_instance();
    }

    //--------------------------------------------------
    //Redirect to https if in the account area without it
    function index()
    {
        if(empty($_SERVER["HTTPS"]) || $_SERVER["HTTPS"] !== 'on')
        {
            $this->obj =& get_instance();
            $this->obj->load->helper(array('url', 'http'));

            $current = current_url();
            $current = parse_url($current);

            if((stripos($current['path'], "/account/") !== false))
            {
                $current['scheme'] = 'https';

                redirect(http_build_url('', $current), 'refresh');
            }
        }
    }
}
?>

STEP 2

Customize the path in the function for which areas of your site should be forced to use HTTPS.

STEP 3

Add the following to system/application/config/hooks.php

/* Force HTTPS for account area */
$hook['post_controller_constructor'] = array(
                                'class'    => 'SecureAccount',
                                'function' => 'index',
                                'filename' => 'SecureAccount.php',
                                'filepath' => 'hooks',
                                'params'   => array()
                                );

Answer 2

I put following lines in ./application/config/config.php file and it works perfectly:

$protocol = ( isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on' ) ? 'https' : 'http';
$config['base_url'] = $protocol.'://www.yoursite.com';

Answer 3

There are few ways to tackle this.

Option 1:

I would probably have the code deployed to both folders, then in the file: /system/application/config/config.php, set your page to:

$config['base_url'] = "http://www.yoursite.com/"; 

or

$config['base_url'] = "https://www.yoursite.com/";

Then in your non-ssl VirtualHost folder, set your config to redirect protected pages by folder to the SSL site:

RedirectPermanent /sslfolder https://www.yoursite.com/sslfolder

Option 2:

Send everything to SSL and keep all your code in one folder

/system/application/config/config.php, set your page to:

$config['base_url'] = "https://www.yoursite.com/";

Other Options

There are some more hacky ways to do this with header() redirects, etc. but I don't think you want to maintain different code bases for this option. I don't recommend this but you could do something like:

$config['base_url'] = “http://” . $_SERVER['http_host'] . “/”;

Answer 4

I can easily, I only define:

$config['base_url'] = '';

CI get base_url automaticaly =D

Answer 5

I solved the problem with in config.php

$config['ssl_active'] = false;
if (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) {
    $config['ssl_active'] = true;
}

$config['base_url'] = ($config['ssl_active'] === true )?"https":"http" . $_SERVER['HTTP_HOST'];

The directory trouble, you can use a simple simbolic link ln -s

Answer 6

another question is similar to this

you can use a protocol-relative url which will keep persistence in the linking in CI.

in your config.php instead of:

$config['base_url'] = 'http://example.com/';

put;

$config['base_url'] = '//example.com/';
