README

Sooner or later you will have to implement sorting of your entities. For example categories, products on main page and so on. And why you should do this by yourself when everything you have to do is to copy & paste?

Installation

The best way to install librette/doctrine-sortable is using Composer:

$ composer require librette/doctrine-sortable

and enable librette extension in your `config.neon

extensions:
	# add this line at the end of your extensions list
	librette.doctrine.sortable: Librette\Doctrine\Sortable\DI\SortableExtension
```

Simplest entity
---------------


```php
namespace App;

use Kdyby\Doctrine\Entities\BaseEntity;
use Librette\Doctrine\Sortable\ISortable;
use Librette\Doctrine\Sortable\TSortable;

/**
 * @ORM\Entity
 */
class Category extends BaseEntity implements ISortable
{
	use TSortable;
	/**
	 * @ORM\Id
	 * @ORM\Column(type="integer")
	 * @ORM\GeneratedValue
	 */
	protected $id;
}
```

Trait TSortable
---------------

There is trait `TSortable` that implements basic sorting methods to your entity.
Everything you need is to call those methods in your service / presenter.

```php
// you can move your entity up or down
$entity->moveUp();
$entity->moveDown();
// or you can put it before / after another one
$entity->moveBefore($anotherEntity);
$entity->moveAfter($anotherEntity);
// also you can set position directly
$entity->setPosition(21);
```

**Don't forget to persist and flush after you finish with sorting!**

```php
$this->em->persist($entity);
$this->em->flush();
```
