Laravel Categorizable Package

This Package is an implementation of a Nested-set hierarchy structure, which enables you to categorize your Eloquent models in a polymorphic way. just use the trait in the model, and you're good to go. There is also a Category model which you can use directly or extend it in your model of choosing.

Requirements

• PHP 8+
• Laravel 8+

Installation

composer require alibayat/laravel-categorizable

Publish and Run the migrations

Laravel Categorizable package will be auto-discovered by Laravel. and if not: register the package in config/app.php providers array manually.

Setup models - just use the Trait in the Model.

Usage

first we need to create some categories to work with. this package relies on another package called laravel-nestedset that is responsible for creating, updating, removing and retrieving single or nested structured categories. Here I demonstrate how to create categories and assign one as the other's child. but you can always check out the tests or refer to package's repository for full documentation. https://github.com/lazychaser/laravel-nestedset

Multiple category structure

there are times that you may wish to have different category structures for different models. in that's the case you can also pass in a type parameter while creating a category. by default, type is set to default. while having a type you can also leverage Eloquent model scopes to filter categories with ease.

Create a Tree while creating new categories

it's also possible to pass a nested structure as the children property to the create method:

Attach the post to category

Detach the post from a category

Attach the post to list of categories

Detach the post from all categories

Sync the categories attached to a post

Check if post is attached to given categories (boolean)

List of categories attached to the post (array [1 => 'BackEnd'])

List of categories IDs attached to the post (array [1, 2, 3])

Get all posts attached to given category (MorphToMany)

Get all posts attached to given category and it's children (Builder)

Methods

On the Base Category Model (or any other model that extends this class), you'll have access to various methods:

full documentation for these methods is available at laravel-nestedset package's readme.
