Installing

There is 3 ways to install this component. You can use Composer, Phar or just include the code directly in your application.

Using phar

Theres is a ready to use phar achive in build/peytz-wizard.phar which includes its own small autoloader that automatically registers with php when included.

<?php

require 'phar://build/peytz-wizard.phar';

var_dump(class_exists('Peytz\Wizard\Wizard'));

Using Composer

You can also install it via composer by using something like the following require.

{
    "require" : {
        "peytz/wizard" : "master-dev"
    }
}

Running tests

$ phpunit

Usage

The api is very simple. You create a Report which properly should be an Doctrine Entity. The Report holds your data and must implement ReportInterface

A Report is required as a contructor argument for a Wizard. A Wizard should be subclassed to add custom steps or use a DependencyInjection framework to inject them into a Wizard object.

A Wizard holds a n number of Steps that implements the StepInterface. There is a basic Step implementation of StepInterface availible.

<?php

namespace Vendor\Wizard;

use Peytz\Wizard\Step;
use Vendor\Wizard\Form\CustomFormType;

class CustomStep extends Step
{
    public function getFormType()
    {
        return new CustomFormType();
    }
}

<?php

namespace Vendor\Wizard;

use Peytz\Wizard\Wizard;
use Peytz\Wizard\ReportInterface;
use Vendor\Wizard\CustomStep;

class CustomWizard extends Wizard
{
    public function __construct(ReportInterface $report)
    {
        parent::__construct($report);
        $this->add(new CustomStep());
    }
}

<?php

namespace Vendor\Wizard;

use Peytz\Wizard\ReportInterface;

class Report implements ReportInterface
{
}

Controller action implementation using Symfony Validator component for validation. Validation Groups are extremely useful for this.

<?php

namespace Vendor\Wizard;

class Controller
{
    protected $validator;

    protected $wizard;

    public function myAction($stepIdentifier)
    {
        $step = $this->wizard->get($stepIdentifier);
        $form = $this->createForm($step->getFormType(), $this->wizard->getReport(), array(
            'validation_groups' => array($step->getName()),
        ));

        if ($_POST) {
            $form->bind($_POST);
            if ($form->isValid()) {
                $this->wizard->process($step);

                // You should proberly save some stuff here? And redirect
            }
        }

        return array(
            'form' => $form,
        );
    }
}

Sample Symfony2 DIC definition

I you want to use DependencyInjection with Symfony2 this is another way of having a Wizard and its steps associated.

The power of using a DIC is that each StepInterface implementation can have optional dependencies. Like building forms programmatically instead of having a FormType.

<container>
    <services>
        <service id="vendor.wizard.custom" class="Peytz\Wizard\Wizard">
            <argument type="service" id="vendor.wizard.custom.report" />
            <call method="add">
                <argument type="service" id="vendor.wizard.custom.my_step" />
            </call>
        </service>
    </services>
</container>
