How to Install Yii Framework in Windows Localhost



Not as I thought, Installing Yii Framework in Hosting is not easy as Installing Yii Framework in Windows because there are problems with that. You can read the problems at my article here : Problems When Installing Yii Framework via Softaculous cPanel. Now I will prove if installing Yii in Windows is very easy, just follow the tutorial below, and read the comparation between installing in local windows and hosting at the end of this tutorial.

To installing Yii Framework in Windows, many people say if you should check the requirement first. Well, for me that's not important, you just have to download the latest XAMPP to installing the latest Apache and MySQL. And to installing XAMPP, you can follow my tutorial here : Fast Way to Installing XAMPP in Windows (Trusted).
  • First, we really should to do is configuring Environment Variables, because to installing Yii we need to run Yiic.bat by Command Prompt. Go to Windows Explorer > My Computer and then right clict at the Properties.
Picture 1. My Computer Properties
  • Click Advanced System Settings > Advanced.
Picture 2. Environment Variables
  • click Environment Variables button.
  • At the System Variables group panel, click the Choose Path and click the Edit button. It will appears the window of Edit System Variable.
Picture 3. Environment Variables
  • At the Variable value field, put ;C:\xampp\php at the end of the value.
Picture 4. Edit System Variable
  • Now, it's time to installing Yii Framework.
  • Download Yii Installation Files at the official website.
  • Extract that file into C:\XAMPP\htdocs\foldername. Rename the folder with easy name like yii777 or etc.
Picture 5. Extract Yii
  • Open Command Prompt, type cd\xampp\htdocs\yii777\framework and then type Enter.
  • Type Yiic webapp C:\xampp\htdocs\yii777 and then type y + Enter.
Picture 6. Installing XAMPP using CMD
  • If your success, then it will show : "Your application has been created successfully".
Picture 7. Yii Installation Success
  • To access the web, run the XAMPP services and then click this link http://127.0.0.1/yii777.
Picture 8 . Yii Home Page
So, you have finished installing Yii in localhost Windows, easy right? But why it cannot installing in web hosting? Allright, it is because the system operation that used by web hosting is not windows, but Linux. Linux cannot run .bat file, that need to installing yii framework by commnad prompt. So, I want to find how to install Yii Framework without command prompt or that .bat file. I believe if I can install without that's all, I can install it in Hosting. So that's all.

Enjoy the coffea!

Fast Way to Install XAMPP in Windows (Trusted)



I have reason why I should write this mainstream tutorial, but this is not about SEO or technique one day one article. I write this tutorial because I want to being this tutorial to be reference for my next tutorial that need to install XAMPP. Well because this tutorial is not too important and too mainstream to read so just go to the point.
  • First, download XAMPP in the official website here : XAMPP Web Site or XAMPP in SourceForge.
  • After download that file, now run the installation as Administrator (recommended).
Picture 1. XAMPP Setup
  • Click Next.
  • Select all components that you need to install (select all recommended), and then type next.
Picture 2. Select Components
  • choose a folder to install XAMPP (C:\XAMPP).
  • Now, just click Next, Next and Next until the installation finish.
All you need is just click next from begining :D | ENJOY THE COFFEA!

Problems When Installing Yii Framework via Softaculous cPanel



I have just installed Yii via Softaculous in cPanel but unfortunately there are some problems. I have known if there are somethings wrong with this softaculous when provide yii installation because when I check the demo in softaculous, it says There is no demo for this script. Just like the picture below :

Picture 1. Yii Demo in Softaculous
So, when I install this framework via Softaculous using this tutorial it has no result when I try to access the web page in browser. I try to digg depper in hosting and then I found something if there is no index.php file in there. Well it is miracle yii framework without index.php file because it is bootstrap file that linked to all file (nobody newbie knows :p).
Picture 2. Yii installation file via softaculous
When you see that files, it looks familiar right? That's true because that's all are yii installation files. It means when you installing Yii Framework via Softaculous, it just copying Yii installation files into your hosting. So you have to install it again using that file. How to do that? Check my next tutorial, Okay :D

Encapsulation, Inheritance, and Polimorfism in OOP PHP



A. Encapsulation

Encapsulation has correlation with visibility or hiding information, it means we create data that cannot be accessed except via method or function that we create. Encapsulation implementation is use function setter and getter that I’ve ever told in the previous OOP article. In that article I’ve given the tutorial about encapsulation when property and method in class is protected by keyword “private or protected”.

Look at the script below that I’ve told in the previous article. In that script I’ve implementing an encapsulation just like the picture below :
Figure 1 Implementing Encapsulation

B. Inheritance

Inheritance means, we can create a new class use existed class, exist class is called parent class and new class that created via parent class is called child class. The purpose from inheritance is to reuse the code we have created with adding new property and method. 

To create a new class that inherit characteristic from another class you must using keyword extends. Here is the formula to creating child class using keyword extends.

child_class extends parent_class

First type the name of child_class and then following by keyword extends and the name of parent_class. Now, let’s create 2 simple class, they are class Parent and Child. Look at the picture below :

Script 1. Implementing Inheritance
<?php
class Parents {
public function helloParent() {
echo "This is parent class ...<br />";
}
}
class Child extends Parents {
public function helloChild() {
echo "This is child class ...<br />";
}
}

$objectChild = new Child();
$objectChild->helloParent();
$objectChild->helloChild();
?>

 If that script run, then this is looks like in browser :
Figure 2 Implementing Inheritance
There are two class appears in browser even we just create one class that’s because class Child inheritance from class Parent. Now we will continue about visibility protected in the previous tutorial, let’s modify class Parent and Child in the script above by adding one protected property in class Parent with name $name and one method in class child with name printParentName(). So this is the script :

Script 2. Implementing Inheritance with Protected Visibility
<?php
class Parents {
protected $name = 'Leonardo Da Vinci';
public function helloParent() {
echo "This is parent class ...<br />";
}
}
class Child extends Parents {
public function helloChild() {
echo "This is child class ...<br />";
}
public function printParentName() {
echo "Parent Name : $this->name <br />";
}
}

$objectChild = new Child();
$objectChild->helloParent();
$objectChild->printParentName();
$objectChild->helloChild();
?>

Property $name in parent class that using protected will run by method printParentName() in child class. When the script run then the name of parent class “Leonardo Da Vinci” will appear even the method run by child class. Look at the picture below :
Figure 3 Implementing Inheritance using Protected Visibility
It is proving that protected visibility can accessed via child class.

C. Polimorfism

Polimorfism is simple, in the previous tutorial you have used polimorfism. Polimorfism is a process creating one or more new object at some class. Let’s we reopen the script in previous tutorial, look at the script below :

Script 3. Implementing Polimorfism
<?php
class people {
private $name;
function __construct($name) {
$this->name=$name;
echo "Constructor : $this->name created <br>";
}
function speaking() {
echo "Hallo, my name is ".$this->name." <br />";
}
function __destruct() {
echo "Destructor : $this->name deleted <br/ >";
}
}
$people1 = new People("People 1");
$people1->speaking();
$people2 = new People("People 2");
$people2->speaking();

?>

Well, the text I colouring is polimorfism ....

Constructor and Destructor in OOP (PHP)



In OOP, you will never separate from constructor and destructor. What is constructor and destructor in OOP? Constructor is special statement (also called special method) that created when an object created (instance of class). If you didn't create the constructor or destructor in a class then constructor and destructor automatically created. When you create $objPeople in the previous OOP tutorial, then constructor and destructor automatically created

Normally, the constructor is created to provide an initial operation to be performed when an object created (inilization object). This is the writting format how to create a constructor

function __constructor(parameter) {
    code
}

Keyword construct should started with double underscore and then give the parentheses (). Among the parentheses, you can give the parameter if you think you need to add parameter. Then you can build your code in constructor.

Eg you create class product, in that class include property of quantity that the initialize value shuld be 0, then the code will look like below :
class barang {
    private name;
    private price;
    private quantity;

    function __construct() {
        $this->quantity = 0;
    }
}

If the constructor created and used when the object created, then destructor is the reverse of constructor. Destructor created and used when the object deleted. In PHP programming, destructor automatically called in your final PHP scripting.

Same like constructor, writing format of destructor begin by double underscore. Here it is :

function __destructor(parameter) {
    code
}

And this another example of constroctor and destructor :

<?php
class people {
    private $name;

    function __construct($name) {
        $this->name=$name;
        echo "Constructor : $this->name created <br>";
    }


    function speaking() {
        echo "Hallo, my name is ".$this->name." <br />";
    }

    function __destruct() {
        echo "Destructor : $this->name deleted <br/ >";
    }

}

$people1 = new People("People 1");
$people1->speaking();
$people2 = new People("People 2");
$people2->speaking();
?>

And this is the result in browser :


In the picture above, there are six teks, the result from calling the constructor, calling method speaking(), and calling destructor. Though you don't put code call method __construct() & method __destruct(). This happen because when you create an object, it's automatically creating constructor for the object. Then when it has used, it will removed from memory. It's automatically the destructor from that object will be called.

Here is the example of the use constructor, destructor, method, object, and property for calculating the student's grade.


<?php
class Score {
    private $task;
    private $middleTest;
    private $finalTest;
    // constructor set first score with 0
    function __construct() {
        $this->task=0;
        $this->middleTest=0;
        $this->finalTest=0;
        echo “Constructor : Task, Middle Test and Final Test Score set to 0.<br /><br />”;
    }
    //function to set task score, set from 0 until 100
    function settask($score) {
        if (($score<=100) && ($score>=0))
            $this->task=$score;
    }
    //function to set value of middle test, set from 0 until 100
    function setmiddleTest($score) {
        if (($score<=100) && ($score>=0))
            $this->middleTest=$score;
    }
    //function to set final test score, set from 0 until 100
    function setfinalTest($score) {
        if (($score<=100) && ($score>=0))
            $this->finalTest=$score;
    }
    //function to get value of task property
    function gettask() {
        return $this->task;
    }
    //function to get value of middle test property
    function getmiddleTest() {
        return $this->middleTest;
    }
    //function to get value of final test property
    function getfinalTest() {
        return $this->finalTest;
    }
    //function to count the last scores
    function getLS() {
        $lastscores=0.2*$this->task+0.3*$this->middleTest+0.5*$this->finalTest;
        return $lastscores;
    }
    //function to view value of task, middle test final test and last scores
    function view() {
        echo    “Task Score : “.$this->task.
            “, Middle Test Score : “.$this->middleTest.
            “, Final Test Score : ”.$this->finaTest.
            “, Last Scores : ”.$this->getLS().“<br />”;
    }
    //destructor to deleting object from memory
    Function __destruct() {
        echo    “<br /><br />Destructor : Task Score,
            Middle Test and Final Test deleted from Memory<br />”;
    }
}
// e.g implementing class Score
$score = new Score();
$score->settask(80); //set task score
echo “Latest Task Score : “.$score->gettask().”<br />”;
$score->setmiddleTest(60); //set middle test score
$score->setfinalTest(80); //set final test score
$score->view();
// final test score has not change, new score is not valid (> 100)
$score->setfinalTest(110);
$score->view();
echo “Last Scores : ”.$score->getLS();
?>

And the looks like in browser is :

Public, Private, and Protected (Member Visibility) in OOP PHP



In OOP we will always find keywords Public, Private, and Protected. These three things are used to determine the visibility of members (properties and functions) that are characteristic of object-oriented programming. Are members globally accessible (public) or accessed by its class (private) or accessed by the class and subclasses. Meanwhile, if the procedural programming members can only be accessed globally.

A. Public

In public visibility, a method or property can be accessed globally. That means it can be accessed on the inside and outside of class or in other words the properties and functions are known globally. In OOP PHP tutorial for Beginers previously, we have made $objPeople which the visibility of properties and function are public.

This is another example of class with public visibility :

Script 1.
<?php
class student {
    public $sid;
    public $name;
    public $point;

    public function processPoint () {
    echo "Students with sid $this->sid <br />";
    echo "name $this->name <br />";
    echo "get point $this->point";
    }
}
$objStudent = new student();
$objStudent->sid = '3310901051';
$objStudent->name = 'Hermanto';
$objStudent->point = 90;
$objStudent->processPoint();
?>

And this is the result looks like in browser
Picture 1. Public member visibility

B. Private

If public can accessed by global  then private visiblity means that the member (method or property) in a class are accessible only within its own class.

Let's modify the script at class student by changing the property visibility to be private.

Script 2
<?php
class student {
    private $sid;
   
private $name;
   
private $point;

    public function processPoint () {
    echo "Students with sid $this->sid <br />";
    echo "name $this->name <br />";
    echo "get point $this->point";
    }
}
$objStudent = new student();
$objStudent->sid = '3310901051';
$objStudent->name = 'Hermanto';
$objStudent->point = 90;
$objStudent->processPoint();
?>

If we run the script 2, it will display an error message because the property sid, name and points have private visibility, so that the data accessed by outside of class can not be done. So how do the private property that is accessible outside of class so that it can be used by objects that need it? The solution is to use the function setter and getter.

Setter is used to create a (set of) value for a property. This function is generally used for properties that have private and protected visibility. Setter is often used to validate incoming data before the data is loaded on a property. While the getter is used to generate (get) a value of the member public, private, or protected from the result.

How to access private member with that function?

Script 3
<?php
class student {
    private $sid;
    private $name;
    private $point;

    function setSid($x) {
        $this->sid=$x;
    }
    function setName($x) {
        $this->name=$x;
    }
    function setPoint($x) {
        $this->point=$x;
    }
    function getSid() {
        return $this->sid;
    }
    function getName() {
        return $this->name;
    }
    function getPoint() {
        return $this->point;
    }

    function Point () {
    echo "Students with sid $this->sid <br />";
    echo "name $this->name <br />";
    echo "get point $this->point";
    }
}
$objStudent = new student();
$objStudent->setSid('3310901051');
$objStudent->setName('Hermanto');
$objStudent->setPoint(90);
$objStudent->point();
?>

In the script above, we use function setters and getters for each property that has a private visibility. Making the value of the function by taking the value setter and getter done by function. In the getter is used "return" value because the getter will return the value of the property taken by the data.

Note how to calling the property after instancing $objStudent, calling the property is done by calling the names function with ($objStudent-> setSid()). Although become longer code lines, but more OOP recommend this method for accessing a Member.

If the script is run in the browser then the result will be the same as the picture below :
Picture 2. Calling private visibility with setter & getter function

C. Protected

Protected almost SAME to the private that can only be accessed by its class and protected can also be accessed by its subclasses. Let's try changing the script 1 and we will change the visibility of the member be protected like the script below :

Script 4
<?php
class student {
    protected $sid;
   
protected $name;
   
protected $point;

    public function processPoint () {
    echo "Students with sid $this->sid <br />";
    echo "name $this->name <br />";
    echo "get point $this->point";
    }
}
$objStudent = new student();
$objStudent->sid = '3310901051';
$objStudent->name = 'Hermanto';
$objStudent->point = 90;
$objStudent->processPoint();
?>

If the script is run in browser then the result will error : cannot access protected property.

The error occurred because the protected class can only be accessed by its class and subclasses. For more detailed discussion of inheritance protected in subclasses will be explained on the nexy tutorials on The Inheritance.

What is AJAX and How to Use it With jQuery



Are you questioning What is AJAX, and How to Use it With jQuery? To answer the long question, we need to start it from the meaning of AJAX. No, it is not football club from Holland but AJAX is asynchronous JavaScript and XML. People use AJAX to load data from a server and then display it on the webpage without the need to reload the page. With AJAX, you will see only part of the website is changed while the other remain the same because the page is not refreshed. If you still confuse, you can open your Gmail and switch from “inbox” to “sent mail”. You will see the content is different but the page is the same. AJAX call is something you do behind the scene.

So, what is the benefit of AJAX?  
Minimize Bandwidth Usage
AJAX can work without reloading page, so you don't need to refresh and excedded your bandwidth usage.
Faster
Facebook is one from many website that using AJAX. When new notifications coming, it will show you the alarm or notification info in right top position of your facebook page, that's work by AJAX. You can imagine how it works without AJAX, you don't know if there are new notifications coming, you should refresh your facebook page to know that.
- User Friendly
You don't need to refresh the page if you want to see the changes.

Now that you know what AJAX is, we are half way. To complete the answer for What is AJAX, and How to Use it With jQuery we need to continue with it application with jQuery. If you wonder why jQuery, people love it because jQuery supports AJAX in fantastic way. Even more, you will find the implementation is very easy. One important thing is to tell the browser whether to catche AJAX or not, especially since different browsers will behave in different ways.

Here is how to do it :
$.ajaxSetup ({
cache: false
});
This is the example :
$.ajaxSetup ({
cache: false
});
var ajax_load = "<img src='img/load.gif' alt='loading...' />";
//  load() functions
var loadUrl = "ajax/load.php";
$("#load_basic").click(function(){
$("#result").html(ajax_load).load(loadUrl);
});
Example of $.ajax with success is:
$.ajax({url:'/'}).done(function(data){});
Now you have the answer for What is AJAX, and How to Use it With jQuery. This is the time to apply it and see what happen.

HTML Basic Part 2



Meet Again ! as Usual This is R1O as the guest Author. I will continue explain the part from the first tutorial in this HTML Series. If you have not yet read the first tutorial i suggest you to read the first one otherwise you will get lost. Trust me ...
So far we have write this code in our text editor
<!doctype>
<html>
</html>
And the last discussion we talk about tag. So now just add the <head> tag opening and closing in the <html> area in your text editor. Like the example below.
<!doctype>
<html>
<head>
</head>
</html>
Now, What is the tag <head> is use for ?
The tag <head> is use for processing advance programming stuff like javascript, PHP, and etc..
Just remember this “ all the cool stuff that you look at the website is processing at here “ the <head> tag “ “.
Allright now we gonna add <title> tag. write this code below on your text editor. And save it. Remember the format of the save file is .html
<!doctype>
<html>
<head>
<title>

</title>

</head>
</html>
<title> tag what’s that?
The <title> tag is use for make title or description on the browser tab.
So now try add the title or description. Type this code on your text editor and save it.
<!doctype>
<html>
<head>
<title>
                My site
</title>

</head>
</html>
It should look like this in your web browser , in this case i use internet explorer:

TITLE TAG

Now your website has a title ! yeah ...
you can change the name as you like this is only the example.


Now let’s jump to the <body> tag. Write the code as seen on below:
<!doctype>
<html>
<head>
<title>
                My site
</title>
<body>
</body>

</head>
</html>

<body> tag ?
<body> tag is use for make the appereance in the web. If you see the website paragraph or picture it’s written this section the <body> tag. I show you the picture so you can get the clearer picture:

BODY TAG

You see the white space is called the <body> area. Where the upper left is starting point to positioning things in the website. Is like the cartesius diagram that we learn from school in mathematic subject. The difference is the starting point instead from the middle in website is start from the upper left.

BODY TAG
That’s for today. We gonna cover how to add somes stuff in  the <body> tag in the next tutorial. So stay tune !

HTML Basic Part 1



HTML BASIC
 Yo folks back again this time with me as a guest writer R1O. Today i’m Gonna Share about how to design a website From the very basic. Do you ever wonder what website is consist of? Well no need to wonder again cause i’m gonna tell ya. Website Is consist of HTML, CSS, JAVASCRIPT, PHP or even you want to make more dynamic you can add Flash and HTML5 Element. This time I’m just want to share about HTML because that i’ve learn so far.

What the heck is HTML ?

HTML Stand for Hyper Text Markup Language. This is the language that computer understand and this is also the backbone of a website.

How Do i Start writing the HTML ?

You can code it on text editor for example : notepad++, Sublime, or the very basic and stunningly beautiful is the notepad from Windows. (belum di link)
Download It first Just click on the example i suggest using notepad++ and install in your damn PC

Ok, what’s next?

Type exactly same as below. .  .
<!doctype>
<html>
</html>
Just Type like that i explain later... and save as .html for example: index.html (you can add the as you like, index html is the common one.

Ok, now what the heck is <!doctype> and <html> </html> ?

The code <!doctype> is the declaration Tag statement and it must be at the top of the HTML File. It means you tell the browser that this is for code in HTML or HTML5. The <html> is the opening tag and the </html> is closing tag. This is the rule of making HTML you must type that two things first.

What is tag?

In HTML language Tag is the code and it wrap the word in <> for example <head> and tag <head> is the opening tag and it have closing tag to it looks like this </head>. The closing tag has the / before the word. Note not all the tag have closing tag for example the <br /> it close on just one line. I explain the tag that i just wrote later in the next tutorial.
