Load Content Scroll Using EXT Core and PHP

June 22nd, 2010 by aditia rahman / No Comments  

     

Extcore is one the Extjs product, but the company name now called sencha, read this why extjs changes their name. If you using full stack Extjs source the Extcore must be included in the source, in this post I want to show how to load content while window scroll from the server using Extcore, this feature maybe useful when users want to see more data than visible on the screen maybe like facebook wall, actually this post is similar to another post i found, but using jquery (they are in 9lessons.info and webresourcesdepot.com), in this example i’m just using one file and the data is hardcoded from array

So lets start, here’s the php code

<?php

$data = array(
    0 => array('post' => 'Post Number 0')
);

for ($i=1; $i<=50; $i++) {
    $tmp_data = array(
        $i => array('post' => 'Post Number ' . $i)
    );
    $data = array_merge($data, $tmp_data);
}

// get next 10 row data,
if (isset($_GET['act'])) {
    $start = ($_GET['page'] * 10) + 1;
    $finish = $start + 10;
    if ($finish <= count($data)) {
        echo '<div class="data newhead">Loaded Data &darr;</div>';
        for ($i=$start; $i<$finish; $i++) {
            echo '<div class="data">'.$data[$i]['post'].'</div>';
        }
    } else {
        echo 'stop';
    }
    exit;
}

?>

Creating Register and Login Form Using EXTJS and CodeIgniter

June 2nd, 2010 by aditia rahman / 86 Comments  

     

Like another tutorial this post will create the basic form login and register using Extjs and Codeigniter, and I want to mix my previous post about Codeigniter Session Library, Extjs Unique Field Validation and using Statusbar in Extjs Window.

1. Setting up the database

Using phpmyadmin in XAMPP I create the database named “ci_extjs_login”, and create simple “users” table, here below is the sql code that I generated from phpmyadmin, for more advance database modelling you can use mysql workbench.

CREATE TABLE  `ci_extjs_login`.`users` (
`id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`username` VARCHAR( 100 ) NOT NULL ,
`password` VARCHAR( 100 ) NOT NULL ,
`email` VARCHAR( 100 ) NOT NULL
) ENGINE = MYISAM ;

When I write this post, a friend of mine asking me how to get the value from all the row in EXTJS grid, she use EditorGridPanel to make the grid editable by it’s user, and submit all edited value in each row to the server  i’m using php to take all the server side process). Actually the idea is very simple, the grid need to have sm config options it is a shorthand for selModel and this config that make the grid can be selected per row, and you can added the checkboxselection model to choose the row that you desired, so trid to make it simple tutorial, and at the of the post you can download the source from this post.

1. Setting the main page
Include the EXTJS file (javascript and css) in html header file, then create single div with an id to where the grid to put on, and i’m using inline css style to centering the div the on the page

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<link rel="stylesheet" type="text/css" href="extjs/resources/css/ext-all.css"/>
<script type="text/javascript" src="extjs/adapter/ext/ext-base.js"; ?>"></script>
<script type="text/javascript" src="extjs/ext-all.js"; ?>"></script>
</head>

/* This should be fill with the EXTJS script code
 * It explain on the next step
 */

// on the body section
<body>
<div id="grid-example1" style="height: 200px;width:600px;margin:0 auto;padding:20px;"></div>

May 7th, 2010 by aditia rahman / 16 Comments  

     

In this post I try to share my code about form validation in EXTJS, so why another EXTJS form validation tutorial? well, the EXTJS default form validation is quite great, but most sample that I’ve found it just using client side validation and the only server side validation is when the user press submit button. So in this post the I modified a bit code about custom form validation in EXTJS, and here I’m not using database. The expected result should be like this

Creating user session checking with CodeIgniter library

April 17th, 2010 by aditia rahman / 15 Comments  

     

When we build web application with user authentification, the application must have user login/logout or signin/signout or whatever you called it, then the system must have user logged feature to check whether the user is logged in or logged out. Session is the most common way to checking it. In Codeigniter, using Session Class you can use simple function inside controller, it’s something like this:

class User extends Controller {

	// constructor class
	function __construct()
	{
		parent::Controller();
		$this->load->library('session');
	}

	function index()
	{
		$this->load->view('user/index');
	}

	function login()
	{
		// if user already logged in, redirect to user index
		if ($this->_is_logged_in())
		{
			redirect('user/index');
		}
		else
		{
			$this->load->view('user/login');
		}
	}

	function register()
	{
		// if user already logged in, redirect to user index
		if ($this->_is_logged_in())
		{
			redirect('user/index');
		}
		else
		{
			$this->load->view('user/register');
		}
	}

	// checking user logged user by registered session
	function _is_logged_in()
	{
		$logged = $this->session->userdata('user_id');
		if ($logged)
		{
			return TRUE;
		}
		else
		{
			return FALSE;
		}
	}
