Laravel 6 Nestable

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:

id	parent_id	name	slug
1	0	T-shirts	t-shirts
2	1	Red T-shirts	red-t-shirts
3	1	Black T-shirts	black-t-shirts
4	0	Sweaters	sweaters
5	4	Red Sweaters	red-sweaters
6	4	Blue Sweaters	blue-sweaters

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])

    'id',
    'category_name',
    'category_slug'
]

html

Configuration for html output.

'html' => [
    'label' => 'name',
    'href'  => 'slug',

Example:

<?php

'dropdown' => [

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.

name	Parameters
isValidForArray	boolean
isValidForJson	boolean
isValidForHtml	boolean
isValidForDropdown	boolean
isValidForMultiple	boolean

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';
});
