SSL (HTTPS) URLs and CodeIgniter

ci logo flame SSL (HTTPS) URLs and CodeIgniterI am a fan of CodeIgniter for its ease of use. I have developed several ecommerce projects using this “beautiful” framework. While working on my first ecommerce project with CodeIgniter, I faced a problem with URLs. The site was suppose to use both “http” and “https”. But with CodeIgnitor we can define one base URL, which can be either “http” or “https”. Then I came up with an idea and now I am going to share that idea with you.

What I am going to do…

We will create secure version of some functions. For this we will make changes in CodeIgnitor’s URL helper(url_helper.php), Config library (Config.php) and Config (config.php)  files. We will be creating secure version of following functions:

  • site_url()
  • base_url()
  • anchor()
  • redirect()

Lets’ start…

First we will add the following config element in the config file:

$config['secure_base_url'] = 'https://examples.com';

Then, open the url_helper.php file (system/helpers/url_helper.php) and add the following codes. You may use a separate helper file if you do not want to alter the url_helper.php file.

if( ! function_exists('secure_site_url') )
{
    function secure_site_url($uri = '')
    {
        $CI =& get_instance();
        return $CI->config->secure_site_url($uri);
    }
}
 
if( ! function_exists('secure_base_url') )
{
    function secure_base_url()
    {
        $CI =& get_instance();
        return $CI->config->slash_item('secure_base_url');
    }
}
 
if ( ! function_exists('secure_anchor'))
{
    function secure_anchor($uri = '', $title = '', $attributes = '')
    {
        $title = (string) $title;
 
        if ( ! is_array($uri))
        {
            $secure_site_url = ( ! preg_match('!^\w+://! i', $uri)) ? secure_site_url($uri) : $uri;
        }
        else
        {
            $secure_site_url = secure_site_url($uri);
        }
 
        if ($title == '')
        {
            $title = $secure_site_url;
        }
 
        if ($attributes != '')
        {
            $attributes = _parse_attributes($attributes);
        }
 
        return '<a href="'.$secure_site_url.'" ' . $attributes . '>'.$title.'</a>';
    }
}
 
if ( ! function_exists('secure_redirect'))
{
    function secure_redirect($uri = '', $method = 'location', $http_response_code = 302)
    {
        switch($method)
        {
            case 'refresh'    : header("Refresh:0;url=".secure_site_url($uri));
                break;
            default            : header("Location: ".secure_site_url($uri), TRUE, $http_response_code);
                break;
        }
        exit;
    }
}

Now, add the following code in Config.php file (system/libraries/Config.php):

    function secure_site_url($uri = '')
    {
        if (is_array($uri))
        {
            $uri = implode('/', $uri);
        }
 
        if ($uri == '')
        {
            return $this->slash_item('secure_base_url').$this->item('index_page');
        }
        else
        {
            $suffix = ($this->item('url_suffix') == FALSE) ? '' : $this->item('url_suffix');
           return $this->slash_item('secure_base_url').$this->slash_item('index_page').preg_replace("|^/*(.+?)/*$|", "\\1", $uri).$suffix;
        }
    }

Now what we have…

Now what we have? We have secured versions of those function. You may now use them as their insecured version. Enjoy coding ;).

cPanel: Class for creating email account and mail forwarder

cpanel logo cPanel: Class for creating email account and mail forwarderThis class can be used to create email account and mail forwarders using PHP, without logging to cPanel. It is an extension of script made by www.zubrag.com. You can access the original link from here http://www.zubrag.com/scripts/cpanel-create-email-account.php.

  2. Unzip the file. This file contains the class file and an example file.
  3. Open the class file and change these variables -

}
else
{
     echo $cp->message;
}
 
// create mail forwarder
$cp->createForwarder('sadat', 'msh@example.com');
echo '' . $cp->message;
 
// delete mail forwarder
$cp->deleteForwarder('sadat', 'msh@example.com');
echo '' . $cp->message;

Paging Class using PHP and MySQL

Based on my last post on paging using PHP and MySQL, I have coded this class. It is very easy to implement and it will save your time. Here is a code snippet to show how simple to use it.

//include the class file
include('Pager.php');
 
//making connection to the database
mysql_connect('localhost', 'root', '');
mysql_select_db('test');
 
//prepare SQL
$sql = 'SELECT * FROM books';
 
//create an object of Pager passing the SQL
$pager = new Pager($sql);
 
//set the url. this is the current page
$pager->url = 'index.php';
 
//set number of rows. by default it is 10
$pager->rowPerPage = 5;
 
//build the pager
$pager->build();
 
//get paged data
$rows = $pager->getPagedData();

Click the download link given below for a copy of the class. It also includes an working example.
