PHP Login Script

noreply@blogger.com (Gunblade IV) — Sat, 19 Nov 2011 01:58:00 +0000

I would like to share my login script for a web based application that i code in PHP. For this script, I'm using session which is then stored in MySQL. This is just a simple script that I made to help one of my friends for his PHP learning process.

For this script, I doubt on the security on login process. I'm no expert in this field. Any suggestion are much appreciated as I'm still learning my way to be a better and DRY programmer. Thou this script does have repetition on certain things especially IP variables which already declare on Login class constructor, still I declare it on every page to check session authentication.

Ubuntu : Apache, PHP & Oracle with oci8 enable Installation

noreply@blogger.com (Gunblade IV) — Thu, 10 Nov 2011 17:14:00 +0000

It's been a while since I need to program PHP with connection to an Oracle database. Usually, I would prefer to design my system to use MySQL or postgreSQL to link up with PHP as a database. But I cannot exclude myself to have to code a PHP system which need to connect to an Oracle DB by a client specific request.

So, as I'm lurking around the Google street to have a good and working guide on how to setup PHP to be able to connect to Oracle - I did found out that there are not many tutorial available on blogs and forums on a working step-by-step Apache, PHP and Oracle installation guide with an oci8 extension enable.

Ubuntu : Extend Battery Life

noreply@blogger.com (Gunblade IV) — Tue, 08 Nov 2011 13:31:00 +0000

As lots of users nowadays are using linux on portable machine such as netbooks and notebooks, there are concerns on Ubuntu users on how they could maximize their battery life as they try to work with their machines as long as possible.

Today, Linux has evolved to suit more user needs such as user-friendly interface, more complicated application for scientific used and also lots of day-to-day applications for home use. Linux not a geek operating system anymore as beginner user can easily change from typical windows operating to linux (any distribution) without any hitch.

Ubuntu : Unity VS Gnome 3

noreply@blogger.com (Gunblade IV) — Sun, 25 Sep 2011 11:10:00 +0000

After a few weeks on an early released of Ubuntu Oneiric 11.10. I know there are a lot of Ubuntu lovers and fans are currently have a pair of itchy hands to try and have a personal experiences on the new version of Ubuntu which brings a lot of improvements on a lot of complains filed from previous version which is Natty Narthwal.

I have been a few of thousands or maybe millions of Ubuntu users who can't wait for the official release of Oneiric gave a development version of Oneiric a run on my laptop. So far, I can rate Oneiric is good-to-go for a testing machine but not for a daily used machine (but who knows if you will gamble your lifetime works with the early testing development version of Oneiric).

Ubuntu : Set Gnome 3 as Default in Oneiric Alpha 3

noreply@blogger.com (Gunblade IV) — Tue, 13 Sep 2011 23:35:00 +0000

This post should be a short post on how to change the default windows manager on the new but not yet official Ubuntu 11.10 Oneiric Ocelot. So far, Oneiric Alpha 3 has just been released a few weeks ago. Thus this released is not yet stable, but some hardcore users might be interested to be the early birds to try and have a peek on the new Ubuntu.

As far as we all already knew, Oneiric will be shipped with capabilities to run Gnome 3 along side with Unity which we might be missing on 11.04 Natty. So most of the anti-unity windows manager will be jumping and singing with joy once the developer team announced that the new version of Ubuntu will be able to run Gnome 3 which so far has been highly rated by most who have tried the gnome-shell.

Ubuntu : Disable 'Universal Access Settings' Panel Icon

noreply@blogger.com (Gunblade IV) — Sun, 11 Sep 2011 11:39:00 +0000

It seem like by default Gnome 3 will display the Universal Access Settings icon on the top panel just in case user is having any disabilities. This is a good decision since now all can install and use linux once they have it installed on their machine without the need to call somebody else just to enable the accessibility functions.

But for me, the icon on top panel of Gnome 3 is just a waste since I do not need it on the first place. So I need to remove it badly and luckily I manage to find a way to disable the icon from appearing on panel.

Ubuntu : Solving Alt+F2 Problem on Gnome 3

noreply@blogger.com (Gunblade IV) — Sun, 11 Sep 2011 10:41:00 +0000

After a distribution upgrade from Natty 11.04 to Oneiric 11.10(currently on development branch), the first things I do is to install the gnome-shell which is being the best fix from 11.04 version. Yes! It is a Gnome 3 shell which able to work side by side with Unity(the default desktop for Ubuntu).

The most important, bad and pain in the ass things i found out that Gnome 3 on Ubuntu 11.10 not working is the Run Shorcut Keyboard Key. By default, the Alt+F2 will bring this run window up, but somehow in 11.10, it did not do anything.

PHP : Why it still the best ?

noreply@blogger.com (Gunblade IV) — Wed, 13 Jul 2011 14:38:00 +0000

I've been doing a poll in Negative Zero Facebook page to survey on 'What programming language currently being demand by Malaysia corporate sector?'. I've listed a few option which is currently being used rapidly by developer around the globe.

The point of having this discussion is to clarify which language are widely used and demanded by corporate sector on hiring a programmer. Surprisingly, I don't include JAVA on the list. I'm wondering why I did not list JAVA on the poll since JAVA is still the best programming language in my opinion. I'm sorry for the unlisted JAVA programming language on the list goes to all JAVA lover out there.

Honestly, I was expecting .NET and Ruby to dominate the poll since this two programming language are currently the most hits on Google keywords. But then PHP come out of no where voted as the most demanded programming language.

Negative Zero Goes Facebook User Friendly

noreply@blogger.com (Gunblade IV) — Sun, 10 Jul 2011 07:27:00 +0000

Negative Zero's blog now move forward and become more user friendly with Facebook user by integrating comments with facebook comments button. This is another step for Negative Zero to support readers interaction with us since lots of internet user nowadays have Facebook accounts.

Well since Google+ is just around the corner on final release, I might take a look on integrating both Facebook and Google+ on comment section but still waiting for announcement from Google+ API to be available on public.

Until then, please enjoy reading and don't forget to LIKE Negative Zero on Facebook by clicking on Like Box on left column of the blog.

PHP Object Oriented Programming

noreply@blogger.com (Gunblade IV) — Wed, 06 Jul 2011 19:15:00 +0000

PHP stand for Hypertext Preprocessor is widely used, generally use as web development. PHP code usually embedded into HTML code and interpreted by a web server with PHP processor module.

PHP can be programmed as Procedural and Object Oriented(OOP). Most likely, tutorial on the internet will teach by using the procedural programming. Most probably, both method will produce the same result if coded in a correct way.

Why OOP? Some might be asking - Why should I start to code in OOP while procedural can do the things without any hiccup? Well I 'll answer it as "Suit yourself, it's your code not mine" if you asked me personally. But if you asked me reason on why I write mostly in OOP approach. The answer then is "I just want to keep myself DRY". DRY in programming world mean Don't Repeat Yourself. If you do read tutorials of tips on programming, you will probably heard this term DRY. Class and Object will make yourself DRY, so does procedural will make yourself WET?

Simple PHP Script to Generate TreeGrid View

noreply@blogger.com (Gunblade IV) — Sun, 03 Jul 2011 00:19:00 +0000

I've been working on PHP which need to generate TreeGrid view. I've tried to find a free script on TreeGrid View but seem like it's hard to find one. Most of the script are shareware. By shareware I mean the cost is more than 10 bucks. I'm not going to waste my money so I decided to write my own script.

The script was written in PHP. Thanks to Apogee for the guide and advise on using recursive function a few years ago. The script cover only basic function to generate Tree Grid view. Feel free to modified, delete, or add codes as long as you the script stay free.

MVC 3 : Create A Simple Blog Application Pt. 3

noreply@blogger.com (Gunblade IV) — Sat, 02 Jul 2011 18:41:00 +0000

For those who missed my last tutorial on MVC on how to create simple blog application can try to review those by links listed below:

Part 1 – Create Simple Blog Application
Part 2 – Create Simple Blog Application
Part 3 - You are reading the tutorial at this moment
Part 4 - Create Simple Blog Application

On previous tutorial, I've cover much on how we develop our blog models using LightSpeed ORM and directly create the database to SQL. So in this tutorial I'll assume that we should have our models working. Previous tutorial did not mention on how we need to set the KeyTable for our database to allow LightSpeed to add new data on the same time add plus one to our Identity Table.

Update : New Clean Look

noreply@blogger.com (Gunblade IV) — Fri, 24 Jun 2011 15:02:00 +0000

Today I manage to find 30 minutes of free time slot to make a tiny adjustment on Negative Zero blog's theme. I did a minor changes on the how readers can easily read my post. Instead of using Allerta as my default fonts, I now change to Calibri for much better clear fonts for my visitor to read.

This should be 4th times Negative Zero themes being edited by me during the whole 4 years of Negative Zero existence. This new theme focus on improving text visibility since my main purpose of writing post is for readers to read. So the new theme will reflex on more white and text rather than box shadow and fancy fonts.

To be honest, this new theme was inspired from Mypapit blogs look and feel. I like the cleaniness and overall feelings when visiting mypapit blog. This should be my permanent themes for a while.

For those who reading this blog by using Internet Explorer(all version) will not be viewing my latest blog themes update since IE doesn't support certain adjustment that I've made. Should I mention anywhere on my blog that this blog is best view with other browser than Internet Explorer? :-P

I hope my precious readers will enjoy this new look and could make full use of my post. Please leave comments and like my blogs on Facebook.

Using NetBeans 7 as PHP IDE

noreply@blogger.com (Gunblade IV) — Mon, 20 Jun 2011 01:58:00 +0000

For few days I've been working on a PHP system for my new company to develop a web based application. I've been spending about 3 – 4 days searching the best PHP IDE that could provide intellisense and code completion that could replace my favorite .NET IDE which is Microsoft Visual Studio(VS).

There are a lot of blogs and reviews on great IDE for PHP programming that could provide intellisense and code completion for PHP but none could replace VS on the first hand. Kudos to Microsoft for the most impressive invention on IDE for C# programming language.

MVC 3 : Create A Simple Blog Application Pt. 2

noreply@blogger.com (Gunblade IV) — Sun, 19 Jun 2011 17:04:00 +0000

We will continue from what we left out on previous tutorial Pt 1. Some recaps on previous tutorial, we have create a new project that we called NegativeZero on our Microsoft Visual Studio(or some might be using Microsoft Web Developer). Since we do not yet touch any code on previous tutorial, so by default the project will be compiled as Default MVC 3 Web Application Internet.

So on this part 2 tutorial, we will be creating our Model for this project. Since we are developing simple but working Blog Application, we should bear in mind that one must has entity in our model. The entity is POST which will keep our record on every post that we will post. And basically, Post entity should have this attributes:

author
date
title
post(which will be the post body)
tags
categories

MVC 3 : Create a Simple Blog Application Pt. 1

noreply@blogger.com (Gunblade IV) — Thu, 16 Jun 2011 18:06:00 +0000

In Part 4, I have covered on how we could create custom dynamic partial view on MVC 3 by using simple javascript. So on this next tutorial, I'll post on something a bit different from partial view. This post will cover on how we could create a MVC 3 web application. At the end of this series of tutorial, we will have a fully working Blog System, which will have login, Posting, Editing, and all basic function of a blog.

This tutorial will be focusing on basic function of Modeling(I'll be using Lightspeed as ORM), Controllers and lastly Razor view engine. I'll also cover on Repositories pattern, use Ajax and many more. Subscribe to this blog in order to follow all the tutorial that will be post in near future.

Repository also generally known to MVC 3 programmer as Repository patterns is a technique to manipulate data from our Models. For example, when we have Models that have several type of attributes (id,name,location) we might need to build a repository that will list all data, list single data, list all data but with only one or some attribute(s) and etc.

When we codes this class, it's is known as Repositories Pattern in MVC term. In this tutorial, I'll explain on how we could use Repositories to simplify our code and reuse it many times without needing to write it every time.

Part 4 : Dynamic Partial View Using Java Script

noreply@blogger.com (Gunblade IV) — Thu, 16 Jun 2011 10:55:00 +0000

Previously on Part 3, I have explain on how we could code on loading partials when needed. Part 3 method is best used on partials that deals with forms and require model parse on loading the view. On this Part 4 tutorial, I'll explain on how we could code dynamic partials that do not require loading delay.

This tutorial will load partial on page load but will set the partial on hidden(but if you would like to display a default partial to being viewed, I'll explain on this later). Some would ask why should I use Partial view instead dump all the codes on one .cshtml files? My answer is simple, to structured and organized my view. This way, I wont have trouble when I need to debug my view codes in future.

MVC 3 : Select Record Which Has Maximum Value In A Column Using LINQ

noreply@blogger.com (Gunblade IV) — Mon, 13 Jun 2011 09:12:00 +0000

Modern programming usually does not use direct query to access data from database. For those who familiar with C# and VB programming will definitely know about LINQ. Basically, LINQ is a set of extensions to the .NET Framework that encompass language-integrated query, set, and transform operations. It extends C# and Visual Basic with native language syntax for queries and provides class libraries to take advantage of these capabilities.

For those who core in PHP programming, you might like to read about PHINQ that based on googlecode projects. I’m not sure which projects does have latest update since most of the project stop around 2009.

Part 3: Create Dynamic Partial View on MVC 3

noreply@blogger.com (Gunblade IV) — Wed, 08 Jun 2011 00:03:00 +0000

Partial view in MVC 3 basically used as a reusable view. For PHP programmer, partial view is like an include that can be reused when needed. Partial view could served one purpose or multi purpose depending on your skills.

For example, the picture below show that a form to add new company(based on Part 2 tutorial) popup once user click on Add button. It's like the form being called once user clicked the button, but the truth is the form already loaded along with the Index.cshtml. When user click the button, an onClick function trigger and display the form as popup. That's the magic of AJAX which can easily implemented with MVC 3.

Ajax call form and display as popup on MVC

In this tutorial, I will write on dynamic partial view. My tutorial will create two partial view, but will only be visible on user request. This tutorial will be using a bit of Ajax. So, let's begin our MVC adventures..

During Part 2, I have covered on how you could make a new Models to manipulate objects which is also known as Data Transfer Object. In this tutorial, I will not cover on models, so I'll just proceed with this tutorial goals.

Part 2: MVC 3 and DataTables with Inline Editor (Selection List)

noreply@blogger.com (Gunblade IV) — Sat, 04 Jun 2011 13:48:00 +0000

THIS TUTORIAL HAD ACTUALLY BEING POSTED EARLIER THIS WEEK. BUT DUE TO SENSITIVITY TO DATA AN PICTURE BEING USED I HAVE TO CHANGE AND USE ANOTHER CODE FOR THIS TUTORIAL. I HOPE THIS VERSION IS BETTER THAN BEFORE. HAVE FUN!

Tonight I would like to share on how we could manipulate data using object into Json in MVC 3 easily. On the same time, we will see how to create and customize JEditable to use Drop Down list with dynamic data we fetch from set of information that we stash in Models.

First of all, this tutorial require a bit knowledge on C#, ASP.NET and JS to clearly understand the example given in this tutorial. Level of skill would be novice(or atleast if you have completed the tutorial given on the microsoft MVC, then you should understand this tutorial)

So let's begin...

To use JEditable with Datatables on MVC, please read this tutorial first before we implement the inline edit with dynamic selection. That's the best tutorial available on the net discussing on how to use DataTables in MVC 3 with Razor view. So I assume in this tutorial, all my readers already have a working DataTables with JEditables working in all columns and rows.

Local Support Ubuntu Malaysia

noreply@blogger.com (Gunblade IV) — Wed, 01 Jun 2011 18:35:00 +0000

It's been a while since I browse around my Ubuntu Loco website. Suddenly tonight, while I was cleaning trash and outdated backup(s) via SSH(Secure Shell), I notice that there is a Local Support section in main Ubuntu-MY website.

Mainly Ubuntu-MY webteam create this section to serve local Ubuntu user with support and help on Ubuntu bugs and guide. But then, it's not being used wisely and now - some of us even forgot the existence of embedded IRC for local support.

Let's us - the Malaysian Ubuntu user start making noise, have a great chat, arguing on silly things and together we solve users problem regarding Ubuntu operating system. Let's bring back the true color and bright spirit to make our so-called-small community bigger and merrier than now.

For those who apply for Official Ubuntu membership, I wish you all the best. And may the board approve your application with joy.
