Sortable Trait

Adds sortable behavior to Eloquent (Laravel) models

Usage

Your model must have position field:

// schema builder example
public function up()
{
    Schema::create('articles', function (Blueprint $table) {
        // ... other fields ...
        $table->integer('position'); // Your model must have position field:
    });
}

Add \Rutorika\Sortable\SortableTrait to your Eloquent model.

class Article extends Model {

    use \Rutorika\Sortable\SortableTrait;
}

Now you can move your entities with methods moveBefore($entity) and moveAfter($entity) (you dont need to save model after that, it has saved already):

$entity = Article::find(1);

$positionEntity = Article::find(10)

$entity->moveAfter($positionEntity);

// if $positionEntity->position is 14, then $entity->position is 15 now

Also this trait automatically defines entity position on the create event, so you do not need to add position manually, just create entities as usual:

$article = new Article();
$article->title = $faker->sentence(2);
$article->description = $faker->paragraph();
$article->save();

This entity will be at position entitiesMaximumPosition + 1

To get ordered entities use the sorted scope:

$articles = Article::sorted()->get();

Sortable groups

if you want group entity ordering by field, add to your model

protected static $sortableGroupField = 'fieldName';

now moving and ordering will be encapsulated by this field.

Sortable many to many

Let's assume your database structure is

posts
    id
    title

tags
    id
    title

post_tag
    post_id
    tag_id

and you want to order tags for each post

Add position column to the pivot table (you can use any name you want, but position is used by default)

post_tag
    post_id
    tag_id
    position

Add \Rutorika\Sortable\BelongsToSortedManyTrait to your Post model and define belongsToSortedMany relation provided by this trait:

class Post extends Model {

    use BelongsToSortedManyTrait;

    public function tags()
    {
        return $this->belongsToSortedMany('\App\Tag');
    }
}

Note: $this->belongsToSortedMany has different signature then $this->belongsToMany -- the second argument for this method is $orderColumn ('position' by default), next arguments are the same

Attaching tags to post with save/sync/attach methods will set proper position

    $post->tags()->save($tag) // or
    $post->tags()->attach($tag->id) // or
    $post->tags()->sync([$tagId1, $tagId2, /* ...tagIds */])

Getting related model is sorted by position

$post->tags; // ordered by position by default

You can reorder tags for given post

    $post->tags()->moveBefore($entityToMove, $whereToMoveEntity); // or
    $post->tags()->moveAfter($entityToMove, $whereToMoveEntity);

Sortable Controller

Also this package provides \Rutorika\Sortable\SortableController, which handle requests to sort entities

Usage

Add the service provider to config/app.php

'providers' => array(
    // providers...

    'Rutorika\Sortable\SortableServiceProvider',
)

publish the config:

php artisan vendor:publish

Add models you need to sort in the config config/sortable.php:

'entities' => array(
     'articles' => '\App\Article', // entityNameForUseInRequest => ModelName
     // or
     'articles' => ['entity' => '\App\Article'],
     // or for many to many
     'posts' => [
        'entity' => '\App\Post',
        'relation' => 'tags' // relation name (method name which returns $this->belongsToSortedMany)
     ]
),

Add route to the sort method of the controller:

Route::post('sort', '\Rutorika\Sortable\SortableController@sort'); 

Now if you post to this route valid data:

$validator = \Validator::make(\Input::all(), array(
    'type' => array('required', 'in:moveAfter,moveBefore'), // type of move, moveAfter or moveBefore
    'entityName' => array('required', 'in:' . implode(',', array_keys($sortableEntities))), // entity name, 'articles' in this example
    'positionEntityId' => 'required|numeric', // id of relative entity
    'id' => 'required|numeric', // entity id
));

// or for many to many

$validator = \Validator::make(\Input::all(), array(
    'type' => array('required', 'in:moveAfter,moveBefore'), // type of move, moveAfter or moveBefore
    'entityName' => array('required', 'in:' . implode(',', array_keys($sortableEntities))), // entity name, 'articles' in this example
    'positionEntityId' => 'required|numeric', // id of relative entity
    'id' => 'required|numeric', // entity id
    'parentId' => 'required|numeric', // parent entity id
));

Then entity with \Input::get('id') id will be moved relative by entity with \Input::get('positionEntityId') id.

For example, if request data is:

type:moveAfter
entityName:articles
id:3
positionEntityId:14

then the article with id 3 will be moved after the article with id 14.

jQuery UI sortable example

Note: Laravel 5 has csrf middleware enabled by default, so you should setup ajax requests: http://laravel.com/docs/5.0/routing#csrf-protection

Template

<table class="table table-striped table-hover">
    <tbody class="sortable" data-entityname="articles">
    @foreach ($articles as $article)
    <tr data-itemId="{{{ $article->id }}}">
        <td class="sortable-handle"><span class="glyphicon glyphicon-sort"></span></td>
        <td class="id-column">{{{ $article->id }}}</td>
        <td>{{{ $article->title }}}</td>
    </tr>
    @endforeach
    </tbody>
</table>

Template for many to many ordering

<table class="table table-striped table-hover">
    <tbody class="sortable" data-entityname="posts">
    @foreach ($post->tags as $tag)
    <tr data-itemId="{{ $tag->id }}" data-parentId="{{ $post->id }}">
        <td class="sortable-handle"><span class="glyphicon glyphicon-sort"></span></td>
        <td class="id-column">{{ $tag->id }}</td>
        <td>{{ $tag->title }}</td>
    </tr>
    @endforeach
    </tbody>
</table>
