ExtJS: Passing Parameter in Function Handler
This is a very short post in my ExtJS posts, when we dealing with handler config in many component sometimes we want to passing the parameter inside the function, so here the simple code on how I do it
Ext.onReady(function() {
var myHandler = function (name){
Ext.Msg.alert('Notification', 'Hello ' + name);
};
var form = new Ext.FormPanel({
frame: true, border: false, buttonAlign: 'center',
url: 'test.php', method: 'POST',
buttons: [{
text: 'Submit Test',
handler: myHandler.createDelegate(this, ['Luffy'])
}]
});
var winLogin = new Ext.Window({
title: 'Function Handler Parameter',
layout: 'fit', width: 200,
height: 80, resizable: false,
border: false,
closable: false, items: [form]
});
winLogin.show();
});
Extjs: Simple Image Gallery Using DataView and PHP
Last week I tried some of the extjs dataview example, it really great, just my thought, why not creating simple image gallery with dataview? All that we need is provided in the example (the panel, fileinputfield, the xtemplate) and this is the page wire frame that I created using Pencil Firefox Plugins.
Cropping Image To Square Dimension With CodeIgniter
I’ve posted similar article before but this time I want to do it with codeigniter, codeigniter have a powerful image manipulation class, in this post I will use it to make thumbnail square from image, let get directly to the code. I make the function inside the controller, this code is cropping image that already located on the server so the image path (not URL) have to be defined.
Cropping Image to Square Dimension Using PHP
When I wrote my previous post about creating image gallery with codeigniter, I browse some popular image sharing service, and I spent most of my time in flickr, till now I think flickr is still the best photo sharing on the net, when we search on flickr, there are many result that displayed only the thumbnail photo, for example you can see on the screen that I captured
Creating user session checking with CodeIgniter library
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;
}
}
}
