Laravel Morph Category

A Laravel package to add polymorphic category support to any model. Easily attach, detach, sync, and query categories using elegant Eloquent relationships.

🚀 Installation

composer require veiliglanceren/laravel-morph-categories

📦 Usage

1. Add Trait to Your Model

use VeiligLanceren\LaravelMorphCategories\Traits\HasCategory;

class Post extends Model
{
    use HasCategory;
}

2. Attach, Detach & Sync Categories

$post = Post::find(1);
$category = MorphCategory::create(['name' => 'News']);

$post->attachCategory($category);
$post->detachCategory($category);
$post->syncCategories([$category->id]);

You can also use slugs or IDs:

$post->hasCategory('news'); // by slug
$post->hasCategory($category); // by model
$post->hasCategory($category->id); // by ID

✅ Use Cases

• Rename tables if you already use categories for something else.
• Replace the model class with your own Category or Categoryable implementation.

⚙️ Configuration

You can publish and customize the config file:

php artisan vendor:publish --tag=category-config

This will create a file at config/category.php with the following structure:

return [

    'tables' => [
        'categories' => 'categories',
        'categoryables' => 'categoryables',
    ],

    'models' => [
        'category' => \VeiligLanceren\LaravelMorphCategories\Models\MorphCategory::class,
        'categoryable' => \VeiligLanceren\LaravelMorphCategories\Models\MorphCategoryable::class,
    ],
];

🔁 Relationships

$post->morphCategories; // Collection of MorphCategory models

$category->morphCategoryables; // MorphToMany to all related models

🔍 Query Scoping

You can query models with specific categories:

Post::withCategory('news')->get();
Post::withCategory($category)->get();
