The hint of zen coding is using css selectors to generate code which is pretty cool like access the dom elements.

For example

1

div#page>div.logo+ul#navigation>li*5>a

can be expanded into:

1
2
3
4
5
6
7
8
9
10

<div id="page">
  <div class="logo"></div>
  <ul id="navigation">
      <li><a href=""></a></li>
      <li><a href=""></a></li>
      <li><a href=""></a></li>
      <li><a href=""></a></li>
      <li><a href=""></a></li>
  </ul>
</div>

When i started to use PhpStorm IDE, i got notification over Performans Issue over Open JDK. Yes i also don’t believe it. PhpStorm offered me that Sun JDK instead of Open JDK. So i decided that switch Sun JDK. This short post is helped us how to install Sun JDK on Ubuntu.

First we need to check that Ubuntu Partners repository is enabled in our apt source list, open /etc/apt/sources.list and uncomment the following line: deb http://archive.canonical.com/ubuntu maverick partner

Of course this is over Ubuntu 10.10 Maverick Meerkat. You can find the correct line in your version.

Then in command line type

1
2

sudo apt-get update
sudo apt-get install sun-java6-jdk

Now we can switch Java provider in our system by typing the following in command line

1

sudo update-alternatives --config java

We will be presented with the screen similar to rhis one

1

There are 2 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                      Priority   Status
------------------------------------------------------------
* 0            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061     auto mode
   1            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061     manual mode
   2            /usr/ lib/jvm/java-6-sun/jre/bin/java        63        manual mode

Press enter to keep the current choice[*], or type selection number: 2

Select the option that has the path /usr/ lib/jvm/java-6-sun/jre/bin/java thats all. Now we check the java version with following command line code.

1

java -version

We should see a similar to the below

1
2
3

java version "1.6.0_24"
Java(TM) SE Runtime Environment (build 1.6.0_24-b07)
Java HotSpot(TM) Server VM (build 19.1-b02, mixed mode)

Installing and setting new kebab project and its vendors are become very boring. I decided to write a simple installer for this problem. If you want, you can also modified for your project. You can find the source code on Github. https://gist.github.com/1158767 . If the link is broken, please send me a comment.

How to use? Run the command at project folder. It will open the ‘www’ folder and install there.

Lets give an example of unique validation.

User:

      unique: true
    email:
      type: string(255)
      unique: true
      notnull: true
    password:
      type: string(255)

As you see userName and email fields are unique. So lets continue the example

<?php
class IndexController extends Kebab_Controller_Action
{
    /**
     * Front-end area index action
     * @return void
     */
    public function indexAction()
    {
        $this->_helper->layout->disableLayout();
        $this->_helper->viewRenderer->setNoRender();

        // This is a new user from sign up form
        $newUser = new Model_Entity_User();
        $newUser->email = 'admin@kebab-project.com';

        // This user is exist already on db with the same email address
        $existUser = Doctrine_Core::getTable('Model_Entity_User')->find(2);
        $exitsUser->email = 'admin@kebab-project.com';

        $validate = new Kebab_Validate_DoctrineTable($newUser);
        if ($validate->isValid()) {
            echo 'New user is valid.';
        } else {
            Zend_Debug::dump($validate->getErrors());
        }

        $validateExist = new Kebab_Validate_DoctrineTable($newUser);
        if ($validateExist->isValid()) {
            echo 'Exist user is valid.';
        } else {
            Zend_Debug::dump($validateExist->getErrors());
        }
    }
}
?>

In this example $validate->isValid() === false because there is a user with same email address on db but <$validateExist->isValid() === false because Kebab_Validate_DoctrineTable check the Doctrine_Record is the same with the row on Db. How it is possible? This is not magic, Kebab_Validate_DoctrineTable uses Kebab_Validate_Unique and in isValid method we check the record is not new with this code ! ($state == Doctrine_Record::STATE_TDIRTY || $state == Doctrine_Record::STATE_TCLEAN)

1

<?php

// Check primary key if the record is not new
$state = $this->_table->state();
if ( ! ($state == Doctrine_Record::STATE_TDIRTY || $state == Doctrine_Record::STATE_TCLEAN)) {
    foreach ((array) $this->_table->getIdentifierColumnNames() as $pk) {
        if (!is_null($this->_table->$pk)) {
            $query->andWhere("$pk != ?", $this->_table->$pk);
        }
    }
}

Then we get tables identifier columns name with $this->_table->getIdentifierColumnNames() and add an andWhere conditional check the primary key is not equal to data.

This means that you can use Kebab_Validate_DoctrineTable’s unique features when update the records.

Best Regards.

kebab.mail.config.from          = "onur.ozgur.ozkan@lab2023.com"
kebab.mail.config.password      = "your_password"

Secondly, we write our actions

<?php

class TestController extend Kebab_Controller_Action
{
    public function contactAction()
    {
        if ($this->getRequest()->isPost()) {
            $param = $this->_helper->param();
            // $param = array('name' => 'Visiter Name', 'email' => 'visiter@email.com', 'body' => 'Hi, This is a message body');
            $configParam = Zend_Registry::get('config')->kebab->mail;
            $smtpServer = $configParam->smtpServer;
            $config = $configParam->config->toArray();

            // Mail phtml
            $view = new Zend_View;
            $view->setScriptPath(APPLICATION_PATH . '/views/mails/'); // we create a contact.phtml for send email
            $view->assign('name', $param['name']);
            $view->assign('email', $param['email']);
            $view->assign('body', nl2br($param['body']));

            $transport = new Zend_Mail_Transport_Smtp($smtpServer, $config);
            $mail = new Zend_Mail('UTF-8');
            $mail->setFrom($configParam->from, 'Contact Form from - '. $param['name']);
            $mail->addTo($param['email'], $param['name']);
            $mail->setSubject('Contact Form from - '. $param['name']);
            $mail->setBodyHtml($view->render('contact.phtml'));
            $mail->send($transport);

            $this->_helper->response(true)->getResponse(); // send success response json format
        }

        // Show contact.form.phtml which user fill and send
    }
}

This is our /view/mails/contact.phtml

<h1><?php echo $this->translate('Contact Form'); ?></h1>
<h2><?php echo $this->translate('Sender'); ?> : <?php echo $this->name; ?> - <?php echo $this->email; ?></h2>
<p><?php echo $this->body; ?></p>

Now you need a view form send form.

Using quotation mark is only viable for a single line, but if you want to span multiple lines, you can do like that

text = %q{This text is
multi line capabilities}

You can use any delimiters of your choice.

]]> <![CDATA[List Management and Kebab_List Classes]]> 2011-07-03T22:59:00+03:00 http://onurozgurozkan.github.com/blog/2011/07/03/list-management-and-kebab-list-classes birekmek.com, our last project at company, was very strange and interest project. The aim of project is choice best supplier for customers. At this project we use a lot of list and flow cart. Lets give some example;

Member Status

  1. Pending: give email and username waiting activation email
  2. Activation: click the activation mail and actived profile
  3. Approved: admin approved the user
  4. Block: admin blocked the user

Order Status

  1. sms: waiting sms activation code
  2. create: when order starts
  3. preparation: when system decides the supplier
  4. shipping: when supplier starts shipping
  5. delivery: when delivery is finised
  6. noservice: If no supplier accepts the order
  7. norouting: ıf there isn’t any available supplier
  8. nothouse: customer isn’t at house
  9. notaccept: customer doesn’t accept the good or service
  10. cancel: order is canceled

At this project the main problem is our customer, owner of project, want to having right change each resource at admin panel. Normally system knows the flow charts but admin may be not know because system is computer but admin is human. So we need to check admin’s choices right options.

Lets give details examples;

  1. User want to sign up so he/she fills the form and waits mail. Now his/her statu is pending. He/she can pass activation, block not approved.
  2. User clicks the activation mail. Now his/her statu is activation. Status can pass approved, block not pending becaouse we check the email.

Simple we can say that status can pass all other. There is a rule.

  1. Customer wanna give order. If his/her first order, we sent SMS. Now order statu is sms. After sms status, order’s statu can pass create or cancel
  2. After preparation status, order can’t cancel because system make a deal with between customer and supplier at that moment.

So if system’s admin wanna change order status from preparation to create or cancel. System couldn’t be calculate statistics right. This is the main problem! What is the solution?

I have wrote classes, Kebab_List overs this problem. The solution is simple we write a rules array and manage the passing between status. First how to use?

    'A' => array('B', 'C'),
    'B' => array('C', 'D'),
    'C' => array('A', 'D'),
    'D' => array()
);

// Create instance
$list = new Kebab_List();

// Set Rules
$list->setRules($rules);

Get all rules

$list->getRules();
/* return  array(
    'A' => array('B', 'C'),
    'B' => array('C', 'D'),
    'C' => array('A', 'D'),
    'D' => array()
); */

Check rights

1

3

$list->canPass('A', 'B'); //true
$list->canPass('B', 'E'); //false
$list->canPass('D', 'B'); //false

Check the items exist

1

$list->hasItem('A') // true
$list->hasItem('X'); //false

Set item

1
2
3

$list->canPass('D', 'B'); //false
$list->setItem('D', array('B', 'C'));
$list->canPass('D', 'B'); //true

Get item

1
2

$list->getItem('A'); // return array('B', 'C');
$list->getItem('D'); // return array('B', 'C');

In the future i want to integrate this classes with Kebab_Translate helper and Doctrine enum data type.

Best Regards.

First of all i want to say that i changed some codes because i was writing the code when i was writing the post in the same time. This morning i coded review and improve the codes. First of all i want to say that you can improve the codes, you can add new repository from git. But these codes are for trial not for products. If you want to use them at products, please first test them. We will start a project for Kebab Installer. You can find more codes and examples there.

First i created a final Helper Class and add getLine and showMenu static methods.

1

3
4
5

9
10
11
12

final class Helper
{
    public static function getLine()
    {
        $handle = fopen ("php://stdin","r");
        return trim(fgets($handle));
    }

    public static function showMenu()
    {
        echo "What do you install?\n"
          . "1. Kebab \n";
    }
}

Developer can use the methods like above because they are static methods.

1
2

$input = Helper::getLine();
Helper::showMenu();

Then i try to write a simple factory design pattern for GitHub Repository Installer. First i write a interface for Repository classes. Every repository class has to install() function.

1
2
3
4

interface IInstaller
{
    public function install();
}

Of course we should define the what is repository. So i write a abstract class Repository whose properties are name, path, url and branch.

1
2
3
4
5
6
7

abstract class Repository
{
    protected $name;
    protected $path;
    protected $url;
    protected $branch;
}

After that i extend KebabProject Class from Repository Abstract Class and implement IInstaller interface.

class KebabProject extends Repository implements IInstaller
{
    protected $name = 'KebabProject';
    protected $path;
    protected $url = 'https://github.com/lab2023/kebab-project.git';
    protected $branch = 'origin/HEAD';

    public function __construct()
    {
        if (!is_dir($this->path = dirname(__FILE__) . '/www')) {
            mkdir($this->path, 0777, true);
        }
    }

    public function install()
    {
        echo "> Installing $this->name\n";

        if (!is_dir($this->path . '/.git')) {
           system(sprintf('git clone %s %s', escapeshellarg($this->url), escapeshellarg($this->path)));
        }

        system(sprintf('cd %s && git fetch origin && git reset --hard %s', escapeshellarg($this->path), escapeshellarg($this->branch)));
    }
}

In this class $name is class name, $path is install directory, $url is git’s url from github, $branch is revision. At __construct method we check the $path and give value, if there isn’t directory, make a directory with mkdir method.

In install methed, first we check $this->path is a directory, if not, we run git clone $url $path method. If $this->path is a directory we do nothing and pass other line. Then we change directory to $this->path and git fetch and git reset.

Of course we need a factory class and method for run this classes.

4
5
6
7

class Installer
{
    public static function factory($type)
    {
        return new $type();
    }
}

This Installer class return the Repository classes. It use like that

// Start here
Helper::showMenu();

switch (Helper::getLine()) {
    case "1":
        echo "You wanna install Kebab Project\n";
        $installer = Installer::factory('KebabProject');
        $installer->install();
        break;
    default:
        echo "\033[31mWrong choice\033[37m\r\n";
}

exit;

If we concat all the codes, we’ll get

Above codes and informations are trials and i am writing them right now. So don’t use them in really life. :) First of all we should understand PHP CLI. So it is a good idea to quick look

  1. http://php.net/manual/en/features.commandline.php
  2. http://www.php-cli.com/php-cli-tutorial.shtml

Now we create a menu because developer want to choices what to install. showMenu function echo a menu with 4 choice.

      . "1. Kebab \n"
      . "2. Doctrine \n"
      . "3. Zend Framework \n"
      . "4. ExtJs \n";
}

Now we need to access the user input all we need to do is read from stdin. getLine function is accessed the input and trimed.

3

5

function getLine()
{
    $handle = fopen ("php://stdin","r");
    return trim(fgets($handle));
}

Now we do action here. I mean get the user choice and install what they want to. But this is an other post issue thats why i just wanna echo a sentence what they wanna install.

switch (getLine()) {

        break;
    case "2":
        echo "You wanna install Doctrine\n";
        break;
    case "3":
        echo "You wanna install Zend Framework\n";
        break;
    case "4":
        echo "You wanna install ExtJS\n";
        break;
    default:
        echo "\033[31mWrong choice\033[37m\r\n";
}

exit;

If we concat the all code, it will be like that…

}

exit;

function getLine()
{
    $handle = fopen ("php://stdin","r");
    return trim(fgets($handle));
}

function showMenu()
{
    echo "What do you install?\n"
      . "1. Kebab \n"
      . "2. Doctrine \n"
      . "3. Zend Framework \n"
      . "4. ExtJs \n";
}

Next post i will explain how we install Kebab Project from git with this install. :) I wish i will be finished until next post :)

It was really suprised me. So how can php access the incoming data. I searched on internet and i found php://input is the solution.

1

file_get_contents("php://input");

The above line provided us with a query string. It is similar to GET Request on the URL. If you parse this query string, you can access the incoming params.

1
2

parse_str(file_get_contents("php://input"),$params);
var_dump($params);

You can find more information at LornaJane blogs over this issue.

But usually we use php framework and we wanna the general solutions over this issue. We use Zend Framework at Kebab Project. All Kebab Project Services are RestFull so we need a good solutions over this issue. I found good article on the weblog and site of Matthew Weier O’Phinney. His helper is very neat and very usefull. Then i wrote our helper which only support JSON response type.

<?php

class Kebab_Controller_Helper_Param extends Zend_Controller_Action_Helper_Abstract {
/**
 * @var array Parameters detected in raw content body
 */
 protected $_bodyParams = array();
 protected $_decodeJsonFieldTypeArray = true;
 //true is array, false is object

 /**
  * Do detection of content type, and retrieve parameters from raw body if present
  *
  * @return void
  */
  public function init()     {
        $request = $this->getRequest();
        $rawBody = $request->getRawBody();

        if (!$rawBody) {
            return;
        }

        if ($request->isPut() || $request->isDelete()) {
            parse_str($rawBody, $params);
            $this->setBodyParams($params);
        }
    }

When you look the init function you can understand the tips. How you can use the Param Helpers at and Controller. You set a variable with this helper.

        $fullName = $params['fullName'];
        $email = $params['email'];
        $language = $params['language'];

// continues

}

I wish this little article help the people who use Kebab Project and develop restfull software with Php.
