DataMapper (DM) is an Object-Relational Mapper that builds on ActiveRecord. Data is loaded from database tables into objects, and relationships can be managed through simple, easy-to-read functions.

DataMapper OverZealous Edition (DMZ) adds several important features to DM, enhancing it’s usage, usually without requiring any code changes.

To install DMZ over DataMapper, the (fairly simple) upgrade process is described here.

DMZ offers these features:
• Everything is an object!
• Easy to setup, easy to use.
• Custom Validation on object properties.
• Lazy Loading (related objects are only loaded upon access).
• Relations and their integrity are automatically managed for you.
• One to One, One to Many, and Many to Many relations fully supported.
• Select data in the style of Active Record (with or without Method Chaining).

You can learn much more from the manual.

Version 1.7.0:

This is a major update to DMZ!

Not only does it include these fantastic new features:
• Automatic Localization
• Amazingly easy Paged Queries
• New methods for streaming query results
• PHPDoc documentation has been added for almost every magic method, which can be used for code-hints in an IDE
• A brand-new extension for finding the row of a given object or id
• And a whole lot more features.

But this version includes a staggering number of small performance improvements than, when added up, can reduce page processing time by as much as 50% (even on simple pages!), and reduce memory overhead by nearly as much, especially when combined the new get_iterated method!

There also have been a variety of bug fixes, and tweaks throughout the code base.

Make sure to check out the changelog — you won’t want to skip this update!

PyroCMS v0.9.8-beta3

2009-12-21T11:55:39-06:00

PyroCMS v0.9.8-dev has finally reached v0.9.8-beta2 so I am looking for some avid fans to help test the system.

The new PyroCMS v0.9.8 will bring a brand new interface and several big performance and usability improvements.

Download
PyroCMS v0.9.8-dev
PyroCMS v0.9.8-beta3

Here is the full changelog so far:

* Added custom CSS area for pages.
* Added GUI editable “Page layouts” to control shared layouts for grouped pages.
* “Check all” boxes and CTRL + Click selecting added to all listing pages.
* Switched module system from Matchbox to Modular Separation (minor performance boost).
* Switched template system from HelpfulParser to Dwoo (dramaticallty improved syntax support, if/else, loops, etc).
* Removed Layout library and replaced with the much cleaner Template library.
* Removed all PHP short-tags.
* Full support for PHP 5.3
* Standardized much of the model code, and removed deprecated CodeIgniter ActiveRecord methods like getwhere().
* Settings library now loads all settings on instantiation, instead of one query-per-setting.
* Added “Preview” modal windows for pages and news, much more accurate than before.
* Draft/Live status added for pages, admins can see pages anyway.
* Swapped Facebox for Fancybox. Mainly iframe support, but it seems generally better.
* Re-enabled page slug editing
* 404 page editable through page manager
* 404 page actually sends 404 headers now!
* Variables module to set variables in admin settings, access via {$variable.variablename}

This is obviously a LOT for me to test by myself, so this will require some help from the community.

If you are Git users you could grab a copy right now and use “git checkout v0.9.8-beta3” or just use the branch “git checkout v0.9.8-dev”.

Layouts and actions in CI

2010-03-15T16:41:59-06:00

To include header, footer and/or sidebar in every view is a really boring practice.

To define a single layout with all the common parts once and then to define the singles action-specific views with just the code that changes sounds better

To do it in CI I’ve used this simple approach.

A) I define a “layout” with all the common parts:

view/site_layout.php:

<html>
<head>
<title>Welcome to CodeIgniter</title>

<style type="text/css">
/*...*/
</style>
</head>
<body>

<?php echo $action?>

<p><br />Page rendered in {elapsed_time} seconds</p>

</body>
</html> 

b) I define an “action” with the action-specific code.

views/welcome_message.php:

<h1>Welcome to CodeIgniter!</h1>

<p>The page you are looking at is being generated dynamically by CodeIgniter.</p>

<p>If you would like to edit this page you'll find it located at:</p>
<code>system/application/views/welcome_message.php</code>

<p>The corresponding controller for this page is found at:</p>
<code>system/application/controllers/welcome.php</code>

<p>If you are exploring CodeIgniter for the very first time, you should start by reading the <a href="user_guide/">User Guide</a>.</p> 

c) Then I load/set the layout in the constructor (or in any other place in the Controller):

controllers/welcome.php:

class Welcome extends Controller {

    function Welcome()
    {
        parent::Controller();
        $this->load->layout('site_layout');
    }
    
    function index()
    {
        $this->load->view('welcome_message');
    }
} 

d) And finally here we have the library that make the things happen:

libraries/my_loader.php:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Loader extends CI_Loader {
    
    var $_layout;

    function layout($layout) {

        $this->_layout = $layout;
        return $this;

    }

    function view($view, $vars = array(), $return = FALSE)
    {
        if (isset($this->_layout)) {
            $this->_ci_cached_vars['action'] = $this->_ci_load(array('_ci_view' => $view, '_ci_vars' => $this->_ci_object_to_array($vars), '_ci_return' => true));
            return $this->_ci_load(array('_ci_view' => $this->_layout, '_ci_vars' => array(), '_ci_return' => $return));

        } else {
            return $this->_ci_load(array('_ci_view' => $view, '_ci_vars' => $this->_ci_object_to_array($vars), '_ci_return' => $return));

        }
    }

} 

With this library you can load your views in the classic CI way, but you can also define a layout for your views.

This is my first contribute to CI. What do you think about it?

DataMapper OverZealous Edition (DMZ) adds several important features to DM, enhancing it’s usage, usually without requiring any code changes.

To install DMZ over DataMapper, the (fairly simple) upgrade process is described here.

DMZ offers these features and more over the original DataMapper:
• In-table foreign keys
• Multiple relationships to the same model
• Better self references
• Add fields from a related model into one query
• Update, view, and query extra columns on join tables
• The ability to generate and use subqueries
• A shareable extension mechanism, including:
• Easy creation of HTML forms,
• Processing posted input,
• Converting to-and-from JSON, CSV, and arrays, and
• Query caching

—————

Version 1.6.2:
NOTE: 1.6.2 includes a minor bugfixes. There are no changes to the core DMZ library.

If you are upgrading from 1.5.x or earlier, this is a major change. There is a good chance DMZ 1.6 could break existing code.

The major changes in this version revolve around the db object. Previously, a single DataBase object was created for the entire application. Changes to any $object->db would affect all other objects, widgets, and whatevers.

DMZ 1.6 introduces a dynamically created DB object. A new one is created every time a query is needed. There are several important reasons for this:

1. Multiple queries can be built simultaneously. If one large query is being built, and needs the results of a different query, it is safe to build, run, and process a second query, without affecting the original.
2. The multiple query functionality makes it possible to create subqueries using the existing Active Record methods. This is very powerful, as you can build the query on the other object, then easily include it in your main query.
3. Subqueries allow DMZ to calculate and include the number of related objects along-side the main object being queried.
4. While not tested, it should be easier that ever to work with multiple databases simultaneously. (You won’t be able to query across them, but no more hacking to get a different DB for different objects!) See db_params on this page.

The dynamic DB can be disabled, but all of the above will no longer work.

Besides this, DMZ 1.6 includes several other new features:
• SQL Functions and expressions can be built using AR-like methods, as well as used in SELECT and query statements.
• You can get the text of a query without running it using get_sql.
• There is a new virtual validation rule, always_validate, that can be used to override the default behavior of ignoring non-required empty fields.

BackendPro 0.6.1

2008-04-06T17:22:37-06:00

Title: BackendPro
Version: 0.6.1
Homepage: BackendPro Project at Kaydoo.co.uk
Download From: Assembla

Well its finished (well up to a point I am happy to release it). BackendPro is finally ready for its first initial public trials. Now some of you I know have been waiting for me to release it while others don’t have a clue what I am talking about. So lets have a look at it shall we?

What is it?
BackendPro is a control panel for developers written in PHP for the CodeIgniter framework. Its not like a CMS where it provides you with a full working system but it does provide you with part of a system. What I mean by this is it provides you with functionality to do all the simple repetitive tasks like authentication, permissions and a basic look and feel for your websites control panel. So using your current PHP and CodeIgniter knowledge you can use BackendPro to built a fully working website quickly since you can concentrate on your application instead of the bits to manage the system.

What can it do then?
It can do lots, not everything I have planned, there is still a lot I want to add like language detection, better error logging (with viewing features) but its been quite a while and I wanted to release something so people can try it. At the moment it has all the following features.

* User Authentication with registration and account activation
* User Permissions by using Access Control Lists (Has Access Control area to manage your websites access permissions)
* Site Preferences (Stored in a database with simple to use UI to update and change preferences)
* Improved Asset Library (Means loading assets onto pages is quick and simple, also has asset caching to speed up the loading of asset files)
* PHP to javascript variable conversion (Easy way to pass PHP variables into your javascript scripts)
* ReCAPTCHA
* Status messages (Can display info/success/warning/error messages to the user)
* Breadcrumb trail creation

For screenshots visit my blog post on BackendPro

Where do I get it?
You can currently get it off my project page and also there are screenshots on my blog if anyone wants.

Is there a Demo?
Yes there is, you can access it here online. Follow the instructions on the login page to get full access. It is reset at 3am (GMT) every day so if it doesn’t work one day check back the next (someone may have been playing about with it).

So there we go, download it and give it a go. Do read the installation instructions first, since its a developer control panel it doesn’t have protective features on everything, so without knowing what your doing you could corrupt the system (The reason for this is otherwise it takes away your ability to make the system how you want). You have been warned.

Flexigrid - Lightweight but rich data grid

2008-03-28T08:13:24-06:00

Hi guys,

This is not really PHP but its one of my open source projects, and you might be able to use it on one of your projects.

Its a data grid similar in concept with the Ext Grid only its pure jQuery love, which makes it light weight and follows the jQuery mantra of running with the least amount of configuration.

Its still in beta until I iron out the kinks.

here’s the link http://webplicity.net/flexigrid

Updated: 6 September 2008
Although I love CI, I’ve decided to move this thread to http://groups.google.com/group/flexigrid/

Updated: 23 April 2008

Seems like Flexigrid has now become a better option for people looking for js data grids as Ext recently announce that it was moving to GPL 3.0

Updated:

Thanks to this guys for creating examples so other people can use Flexigrid, and made my life a little easier:

A3M - Account Authentication & Authorization Module

2010-02-06T04:48:54-06:00

Key Features
1. Sign Up, Sign In (with remember me) and Sign Out
2. Verification email & Reset Password email
3. reCAPTCHA support (optional)
4. SSL support (optional)
5. Language file support
6. Sign In “Fail Attempt Offset” before user has to always solve the captcha (this is google style. Basically you can keep trying over and over… at human speed.)
8. Semantic XHTML views (nearly… lol)
9. Actively supported by developer

Design Goals
1. User Experience (See demo here)
2. Create code that is easily re-purposed - loosely coupled and follows CI PHP Style Guide
3. Adhere to security best practices - takes salt hash, sql injection, xss, etc in to consider
4. Proper MVC separation (working with and without Modular extensions… all credit to wiredesignz)
5. Reduce code bloat - by reused CI Core code as far as possible, form_validation, sessions, etc
6. Optimal performance - Minimal autoloading, don’t xss_clean for no good reason, etc
7. Configurable via config file - if it’s not in there it’s was likely a design decision, feel free to question
8. Everything is built layer by layer first - CSS and JS optional because it can be stripped away and everything work the same. Degrades gracefully.

Development Roadmap
1. AJAX validation on client side - Will be built using JQuery but since the code is well separated you can throw it away easily if you don’t want this
2. Signin/Signup with Facebook, Twitter and OpenID (google, yahoo, etc)
3. Flexible Authorization access control based on roles and permissions
3. Change password, email and username - these actions requires currently password

Caveat: This module uses query strings. This might be controversial but I really honestly think not using GET totally is quite inflexible. I always settle for a mixture of segment based and GET. With that said, if you’re a segment based purist the code should be easily modified to remove GET. The other one is that I’m using CI Sessions, I love it! I did modify its certain short comings but it’s does the Session job well (and secure) imo.

Much work went into this and you free to use it as you please. All I ask is that you contribute back any bugs fixes, improvements and other thoughts you have so that we can keep improving this module. This is still unfinished work and i’m just upload it early to get feedback from the community.

Download Package

Installation Steps
1. Download, extract, upload the ‘a3m’ folder
2. Run sql script a3m/a3m.sql
3. Config your database connect
4. In module config, turn on reCAPTCHA (optional)
5. In module config, turn on SSL (optional)

Change Log

v0.3
1. Uses phpass to hash passwords
2. Signin with Google, Yahoo, AOL, MySpace and OpenID
- with support for SREG, AX and PAPE

v0.4
1. Total ‘refactor’ of codes. Reorganization of codes
2. Sign in with Google, Yahoo!, AOL, Twitter, MySpace, Facebook and any OpenID Provider
3. Not yet done: forget password, verify email, account management. (to do in v0.5)

Modular Separation - PHP5 (Modules)

2009-07-01T22:38:33-06:00

I have attached a set of module library extensions which provide the modular separation part of the Modular Extensions HMVC libraries, without the HMVC component.

This could be considered as an alternative to using Zach’s Matchbox libraries for using modules in an application.

Feel free to test drive this as you wish. Thanks.

The most recent version is 1.11
