The ShippableInterface
======================

   We're sorry but **this documentation section is outdated**. Please have that in mind when trying to use it.
   You can help us making documentation up to date via Sylius Github. Thank you!

In order to handle your merchandise through the Sylius shipping engine, your models need to implement **ShippableInterface**.

Implementing the interface
--------------------------

Let's assume that you have a **Book** entity in your application.

First step is to implement the simple interface, which contains few simple methods.

.. code-block:: php

    namespace Acme\Bundle\ShopBundle\Entity;

    use Sylius\Component\Shipping\Model\ShippableInterface;
    use Sylius\Component\Shipping\Model\ShippingCategoryInterface;

    class Book implements ShippableInterface
    {
        private $shippingCategory;

        public function getShippingCategory()
        {
            return $this->shippingCategory;
        }

        public function setShippingCategory(ShippingCategoryInterface $shippingCategory) // This method is not required.
        {
            $this->shippingCategory = $shippingCategory;

            return $this;
        }

        public function getShippingWeight()
        {
            // return integer representing the object weight.
        }

        public function getShippingWidth()
        {
            // return integer representing the book width.
        }

        public function getShippingHeight()
        {
            // return integer representing the book height.
        }

        public function getShippingDepth()
        {
            // return integer representing the book depth.
        }
    }

Second and last task is to define the relation inside ``Resources/config/doctrine/Book.orm.xml`` of your bundle.

.. code-block:: xml

    <?xml version="1.0" encoding="UTF-8"?>

    <doctrine-mapping xmlns="https://doctrine-project.org/schemas/orm/doctrine-mapping"
                      xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance"
                      xsi:schemaLocation="https://doctrine-project.org/schemas/orm/doctrine-mapping
                                          https://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">

        <entity name="Acme\ShopBundle\Entity\Book" table="acme_book">
            <!-- your mappings... -->

            <many-to-one field="shippingCategory" target-entity="Sylius\Bundle\ShippingBundle\Model\ShippingCategoryInterface">
                <join-column name="shipping_category_id" referenced-column-name="id" nullable="false" />
            </many-to-one>
        </entity>

    </doctrine-mapping>

Done! Now your **Book** model can be used in Sylius shippingation engine.

Forms
-----

If you want to add a shipping category selection field to your model form, simply use the ``sylius_shipping_category_choice`` type.

.. code-block:: php

    namespace Acme\ShopBundle\Form\Type;

    use Symfony\Component\Form\FormBuilderInterface;
    use Symfony\Component\Form\AbstractType;

    class BookType extends AbstractType
    {
        public function buildForm(FormBuilderInterface $builder, array $options)
        {
            $builder
                ->add('title', 'text')
                ->add('shippingCategory', 'sylius_shipping_category_choice')
            ;
        }
    }
