CodeIgniter 1.7 Professional Development book review

Unfortunately it won't make you a CodeIgniter expert.

A couple weeks ago Packt publishing contacted me to review a book they had recently published, called CodeIgniter 1.7 Professional Development by Adam Griffiths.

The preface states the book will take you "beyond the ... user guide and into more advanced subjects". It's not obvious what advanced subjects are covered. I assume the chapters "User Auth", "User Auth 2", "Building Large Scale Apps", "Web services" are what is referred to here, as these seem to be the only chapters not covered by CodeIgniter's user guide. With the exception of "Deploying and…

Database driven routes in CodeIgniter with caching

A faster, simpler and easier solution to database driven routes in CodeIgniter.

Don't know what I'm on about? Read my previous article on database driven routes.

Prerequisites

Step 1

Define 3 new methods in your routes model (..system/application/models/route.php).

function save()
{
    parent::save();
    $this->cache();
}

function delete()
{
    parent::delete();
    $this->cache();
}

/**
 * Writes contents of database table to a cache file.
 *
 * @return void
 */
    function cache()
    {
        $data[] = "get()->all as $value) 
        {
        $data[] = '$route["' . $value->route .…

Django style comments module for Kohana 2.3









The comments module allows you to quickly attach comments to models without creating extra tables or columns in your database.

Download

comment.zip

Install

Unzip and copy the folder to the Kohana modules directory. Then edit the modules array in your configuration file (application/config/config.php) to include the path to the comments folder.

Your modules array should look similar to this.

$config['modules'] = array
( 
    // MODPATH.'auth',      // Authentication
    // MODPATH.'kodoc',     // Self-generating documentation
    // MODPATH.'gmaps',     // Google Maps integration
    // MODPATH.'archive',   // Archive utility
    // MODPATH.'payment',   // Online payments…

Database driven routes in CodeIgniter









Using a pre_system hook the routes array can be populated from your database.

A route is a CodeIgniter controller action alias. Used to build search engine friendly sites. eg posts/database-driven-routes-in-codeigniter is mapped to posts/get/2

Step 1

Define the hook by inserting the code below into the hooks.php file ( ..system/application/config/hooks.php ).

require_once BASEPATH."application/config/database.php";

$hook['pre_system'] = array(
                                'class'    => 'Router_Hook',
                                'function' => 'get_routes',
                                'filename' => 'Router_Hook.php',
                                'filepath' => 'hooks',
                                'params'   => array(
                                    $db['default']['hostname'],
                                    $db['default']['username'],
                                    $db['default']['password'],
                                    $db['default']['database'],
                                    $db['default']['dbprefix'],
                                    )
                                );


This is a pre system hook, which means it is called before any routing has occurred. This hook will call…

Configure CodeIgniter to run on two servers









Using a dynamicly defined constant in the index.php file, CodeIgniter can be set up to run on two servers.

I have found this really speeds up my development time, especially if used along with Bazaar Upload for Web. With this feature, the same CodeIgniter installation can run on two servers without the need to change configuration variables.

Step 1

To implement this feature into CodeIgniter, edit the index.php file, and include the following code at the top.

if ($_SERVER['SERVER_NAME'] == 'localhost')
{
 //Development enviroment.
 define('SITE_LIVE', FALSE);
}
else
{
 //Live enviroment.
 define('SITE_LIVE', TRUE);
}


The code determines…
