Only afterward did I got a chance to test out CodeIgniter Database Library or ActiveRecord Library on project using MySQL. At this point, the simplicity of ActiveRecord really caught my attention but how would it be enough compared to ADOdb when using Oracle Database?

Introduction

Bare in mind, while CodeIgniter have the advantage with ActiveRecord, ADOdb Database Abstraction Layer also equipped with it’s own ActiveRecord or Object Relation Mapping but in this article I would only made comparison between CodeIgniter Database Library, CodeIgniter ActiveRecord Library and ADOdb Database Abstraction Layer (without the ActiveRecord).

ADOdb as CodeIgniter Library

You can get the ADOdb Database Abstraction Layer for CodeIgniter Library from CodeIgniter Wiki. However I personally have modify the code to make it more integrated with CodeIgniter available at Ext.CI GoogleCode page.

$today_date = date('Y-m-d');
$tmrw_date = date('Y-m-d', strtotime("+1 day"));
$sql = "SELECT * FROM my_table
    WHERE my_datetime BETWEEN '" . $today_date . "' AND '" . $tmrw_date . "'";

However this method might return false positive result if the web server and database server doesn’t have it date and time synchronized. From my point of view, it best to let the database server have the full control to insert, update or compare the dates. So what the alternative? You can check the full specification from MySQL Date and Time Functions but I would opt for DATEDIFF if you specifically want to compare with today date.

SELECT * FROM my_table
    WHERE DATEDIFF(my_datetime, SYSDATE())=0

setcookie("sevisitor", 1, time()+3600,
    SITECOOKIEPATH, COOKIE_DOMAIN, false, true);

There are multiple alternative but for it work perfectly on multiple installation.

There are alternative with the use of “callback” to by creating an additional method inside your Controller. The solution is good if you have a complex filtering but why bother when all you need to do is a simple RegExp verification. Based on my Twitter status:

Based from a reply to the status.

I took the challenge of extending Form Validation Library to add support for Regular Expression test. As a result here MY_Form_validation.php. The changes was minimal but since I need to tweak some of the existing method to allow the special character such as | and [ ] to be use in our Regular Expression the LOC for this modify is quite big.

Now you can add rule such as:

$this->form_validation->set_rules(
    'username',
    'Username',
    'trim|required|expression:/^([a-zA-Z0-9\.\-\_\|]{1,50})$/|xss_clean'
);

As you can see, an additional rule has been set with expression:/^([a-zA-Z0-9\.\-\_\|]{1,50})$/. With this new rule you can safely reject request such as below (with proper error message).

Here’s my first (and currently only) daughter Nura Aesha Safia binti Mior Muhammad Zaki.

To make the learning process much easier to understand I would actually try to convert CodeIgniter From Scratch: Day 5 – CRUD from Nettuts+ from using available libraries to Ext.CodeIgniter CRUD Library.

Requirements and Basic Informations

• is based and developed on CodeIgniter 1.7.1, it might work with previous version but please do test it out first.
• requires Table, Pagination, Form (Ext.CodeIgniter Library), Form Validation libraries and Form helper.
• callback can be optimized with Template Library for Ext.CodeIgniter.
• your model code can be minimized with ActiveRecord, you may require more works if using raw SQL.

Disclaimer

This library is not as simple as implementing using Scaffolding Library for CodeIgniter but more to minimizing your development time to write code in CodeIgniter.

Getting Started

To use the Template library, you have to checkout a copy of latest Ext.CodeIgniter or grab the following files:

• http://myci.googlecode.com/svn/trunk/system/application/libraries/CRUD.php
• http://myci.googlecode.com/svn/trunk/system/application/libraries/Form.php

<title><?php wp_title('--',true,'right'); ?> <?php bloginfo('name');?></title>

I prefer a more informative title display to improve SEO for your blog/website.

<?php
function seo_title()
{
    $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
    wp_title('&laquo;', true, 'right');

    if ($paged > 1)
    {
        echo ' Page ' . $paged . ' &mdash;';
    }

    echo ' ';
    bloginfo('name');

    if (is_home() && $paged === 1)
    {
        echo ' &mdash; ';
        bloginfo('description');
    }
}
?>
<title><?php seo_title(); ?></title>

The Rounding Mechanism is a method whereby the total bill amount (including goods and services subject to tax) is rounded upwards or downwards to the nearest multiple of 5 sen. In this regard, total bill amount that ends in 1, 2, 6 and 7 sen will be rounded down while 3, 4, 8 and 9 sen will be rounded up to the nearest multiple of 5 sen.

For example, a total bill amounting to RM82.01 will be rounded down to RM82.00. If it amounts to RM82.04, it will be rounded up to RM82.05.

Here’s two different version if you ever need it:

PHP

Credit Resipi PHP

function nearest_5cent($val) {
    return round($val*20)/20;
}

JavaScript

var nearest_5cent = function(val) {
	return (Math.round(val*20)/20);
}

Google Chrome Frame is an early-stage open source plug-in that seamlessly brings Google Chrome’s open web technologies and speedy JavaScript engine to Internet Explorer. With Google Chrome Frame, you can:

• Start using open web technologies – like the HTML5 canvas tag – right away, even technologies that aren’t yet supported in Internet Explorer 6, 7, or 8.
• Take advantage of JavaScript performance improvements to make your apps faster and more responsive.

With only 1KB+ It would cut-down development time to debug and make things work in Internet Explorer, no more CSS hack or JavaScript hack to recreate the same feature we would be able to gain from other modern browser. But before I jump into the Google Chrome Frame bandwagon I would like to see some questions answered:

• Does it carry Internet Explorer original User Agent string or does it have it’s own?
  
• Does it still check for CSS Conditional Comments?

This is a random post… visit my flickr photostream for more pictures.

For someone who spent 3 years maintaining my own PHP Framework I find it hard to understand why CodeIgniter bundle in a Template Library. There are actually a few good 3rd party Template Engine which you can find for CodeIgniter but let me share with you a port over Template Library for my so call own PHP Framework.

Requirements and Basic Informations

• is based and developed on CodeIgniter 1.7.1, it might work with previous version but please do test it out first.
• the library is build on top of Loader and Output Library allowing you to fully utilize caching, profiler output etc.
• support Parser Library.

Getting Started

To use the Template library, you have to checkout a copy of latest Ext.CodeIgniter or grab the following files:

• http://myci.googlecode.com/svn/trunk/system/application/libraries/Template.php
• http://myci.googlecode.com/svn/trunk/system/application/config/application.php

Setup Template Folder

You will need to create a folder ./public/styles/default/ at the root folder of your CodeIgniter installation. A terminal command equivalent to this is:

> mkdir -p public/styles/default

Setup Template File

For this example let just make a simple template, by default the Template Class will look for “index.html”.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
        <title>{{PAGE-TITLE}}</title>
        <link href="{{STYLE-URI}}css/all.css" media="all" rel="stylesheet" type="text/css" />
    </head>
    <body>
        <div id="header">
            <h1>{{TITLE}}</h1>
            <div id="navigation">{{NAVIGATION}}</div>
        </div>
        <div id="content">
            {{CONTENT}}
        </div>
        <div id="footer">
            <p>{{FOOTER}}</p>
        </div>
    </body>
</html>

Initializing the Template Class

he following code loads and initializes the template class based on your configuration settings

$this->load->library('Template');

Configuration

Open system/application/config/application.php and go to line 13 and 24.

/*
|--------------------------------------------------------------------------
| Base Site Name
|--------------------------------------------------------------------------
|
| Name of your site/application, e.g:
|
|    My First Website
|
*/
$config['site_name'] = 'AdsMalaya';

/*
|--------------------------------------------------------------------------
| Template Option
|--------------------------------------------------------------------------
|
| Enable you to configure template option
| Default template: <your-site>/public/styles/<theme>/<filename>.html
*/
$config['template']['theme'] = 'default';
$config['template']['filename'] = 'index.html';

Here you can modify the title of your application or site and the folder and filename of the default template.

$this->ui->set_output()

There are 3 possible output type: html (default), text or json (require json_encode to be enabled)

$this->ui->set_output('json');

Only html output will load the template file.

$this->ui->set_title()

$this->ui->set_title('Example Page');

The function will only set page title, while application/site title is only editable through the configuration file.

$this->ui->set_template()

$this->ui->set_template('feedmalaya');

The template engine will use folder ./public/styles/feedmalaya/ instead of the one specified in the configuration file.

$this->ui->set_file()

$this->ui->set_file('site.html');

There are time when you need to have different set of layout but using the in the same theme.

$this->ui->data()

Set output for text or json. Here an example how to use it.

$data = array (
    'success' => TRUE,
    'text' => 'Some text'
);
$this->ui->set_output('json');
$this->ui->data($data);
$this->ui->render();

$this->ui->view(‘filename’, $data, $group)

The method is almost identical to $this->load->view with the exception of the third parameter.

$data = array (
'success' => TRUE,
'text' => 'Some text'
);
$this->ui->view('myfile', $data, 'sidebar');
// will render to sidebar
$this->ui->render();

You can embed the view to any of the following group:

• header
• navigation
• content (default)
• sidebar
• footer

$this->ui->append(’some text’, $group);

Append existing template group with some text.

$heading = heading('Hello world', 2);
$this->ui->append($heading);

$this->ui->prepend(’some text’, $group);

Prepend existing template group with some text.

$heading = heading('© CodeIgniter', 2);
$this->ui->prepend($heading, 'footer');

Conclusion

How you can make use of it as I made in my project. If you manage to fine any bug please report it to us, Thank you.

|    ['dbprefix'] You can add an optional prefix, which will be added
|                 to the table name when using the  Active Record class
$db['default']['dbprefix'] = "feed_";

For example: TABLE feed_item

$this->db->get('item');

Many might not know that you can also use it with normal database query using 'swap_pre'. In ./system/application/config/database.php

|    ['dbprefix'] You can add an optional prefix, which will be added
|                 to the table name when using the  Active Record class
$db['default']['dbprefix'] = "feed_";
$db['default']['swap_pre'] = "{PRE}";

So now you can actually use.

$sql = "SELECT * FROM {PRE}item";
$query = $this->db->query($sql);

$sql = "SELECT * FROM item";
$query = $this->db->query($sql);
foreach( $query->result_array() as $row ) :
    $this->db->query("UPDATE relationship
        SET rel_date=?
        WHERE (rel_value=? AND rel_type=1)", array(
        $row['item_datetime'],
        $row['item_id']
    ));
endforeach;

This actually can be simplify using only MySQL query such as:

UPDATE relationship r, item i
    SET r.rel_date=i.item_datetime
    WHERE (r.rel_value=i.item_id AND r.rel_type=1)

function roundNextNearest(num, acc) {
    if ( acc < 0 ) {
        return Math.round(num*acc)/acc;
    } else {
        var value = Math.round(num/acc)*acc;
        if (value < num) {
            value += acc;
        }
    }
    return value;
}
