README
Info:
This repository is a clone of Laravel Nestable which is "Archived" by the developer. We'll try to maintain it as much as possible for future releases of Laravel.
Laravel Nestable to work with recursive logic. Category level there is no limit but this may vary depending on your server performance. Allow the 100000 recursion process execution since PHP 5.2. More info
Install
composer require webreinvent/laravel-nestable
Then
Add to app.php the Service Provider file.
Nestable\NestableServiceProvider::class
Then add app.php Facade file again.
'Nestable' => Nestable\Facades\NestableService::class
Finally run the artisan command:
php artisan vendor:publish --provider="Nestable\NestableServiceProvider"
That's it!
Basic Usage with Eloquent
Suppose that the data came from a database as follows.
Category table:
Example 1:
<?php use Nestable\NestableTrait; class Category extends \Eloquent { use NestableTrait; protected $parent = 'parent_id'; }
Note: $parent variable refers to the parent category (Default parent_id)
<?php $categories = Category::nested()->get();
Query result:
<?php array:6 [ 0 => array:5 [ "id" => 1 "name" => "T-shirts" "slug" => "t-shirts" "child" => array:2 [ 0 => array:5 [ "id" => 2 "name" => "Red T-shirts" "slug" => "red-t-shirts" "child" => [] "parent_id" => 1 ] 1 => array:5 [ "id" => 3 "name" => "Black T-shirts" "slug" => "black-t-shirts" "child" => [] "parent_id" => 1 ] ] "parent_id" => 0 ] 1 => array:5 [ "id" => 4 "name" => "Sweaters" "slug" => "sweaters" "child" => array:2 [ 0 => array:5 [ "id" => 5 "name" => "Red Sweaters" "slug" => "red-sweaters" "child" => [] "parent_id" => 4 ] 1 => array:5 [ "id" => 6 "name" => "Blue Sweaters" "slug" => "blue-sweaters" "child" => [] "parent_id" => 4 ] ] "parent_id" => 0 ] ]
For html tree output:
<?php Category::renderAsHtml();
Output:
<ul> <li><a href="">T-shirts <ul> <li><a href="red-t-shirt">Red T-shirt</a></li> <li><a href="black-t-shirts">Black T-shirts</a></li> </ul> </li> <li><a href="">Sweaters <ul> <li><a href="red-sweaters">Red Sweaters</a></li> <li><a href="blue-sweaters">Blue Sweaters</a></li> </ul> </li> </ul>
For dropdown output:
<?php Category::attr(['name' => 'categories']) ->selected(2) ->renderAsDropdown();
Output:
<select name="categories"> <option value="1">T-shirts</option> <option value="2" selected="selected"> Red T-shirts</option> <option value="3"> Black T-shirts</option> <option value="4">Sweaters</option> <option value="5"> Red Sweaters</option> <option value="6"> Blue Sweaters</option> </select>
Selected for multiple list box:
->selected([1,2,3])

Configuration
The above examples were performed with default settings. Config variables in config/nestable.php file.
body
The body variable should be an array and absolutely customizable.
Example:
<?php 'body' => [ 'id', 'category_name', 'category_slug' ]
html
Configuration for html output.
Example:
<?php 'html' => [ 'label' => 'name', 'href' => 'slug', ]
dropdown
Configuration for dropdown/listbox output.
Example:
<?php 'dropdown' => [ 'prefix' => '-', 'label' => 'name', 'value' => 'id' ]
Using Independent Models
Include the Nestable facade.
<?php use Nestable; $result = Nestable::make([ [ 'id' => 1, 'parent_id' => 0, 'name' => 'T-shirts', 'slug' => 't-shirts' ], [ 'id' => 2, 'parent_id' => 1, 'name' => 'Red T-shirts', 'slug' => 'red-t-shirts' ], [ 'id' => 3, 'parent_id' => 1, 'name' => 'Black T-shirts', 'slug' => 'black-t-shirts' ] // and more... ]);
For array output:
$result->renderAsArray();
Validators
It controls the structure of the data. They also made the rendering process with a second parameter control after they.
Example 1:
<?php Menu::make($categories)->isValidForHtml(); // return true or false
Example 2:
<?php Menu::make($categories)->isValidForHtml(true); // return html string if data valid
Macros
<?php Nestable::macro('helloWorld', function($nest, $categories) { return $nest->make($categories)->active('sweater')->route(['tests' => 'slug'])->renderAsHtml(); });
Call the above macro:
<?php $categories = [ [ 'id' => 1, 'parent_id' => 0, 'name' => 'T-shirt', 'slug' => 'T-shirt' ], [ 'id' => 2, 'parent_id' => 0, 'name' => 'Sweater', 'slug' => 'sweater' ] ]; Nestable::helloWorld($categories);
Helper
<?php nestable($data)->renderAsHtml();
<?php nestable()->make($data)->renderAsHtml();
<?php nestable()->macro('helloWorld', function() { return 'Hello Laravel'; }); // run nestable()->helloWorld();
