README

Automatic slug generation for Eloquent models with scoped uniqueness, history, and transliteration.

Requirements

• PHP 8.2+
• Laravel 11 or 12

The PHP intl extension is recommended for best transliteration results (falls back to iconv then a simple strip).

Installation

composer require philiprehberger/laravel-slug-generator

The service provider is auto-discovered via Laravel's package discovery. No manual registration is required.

Publish configuration

php artisan vendor:publish --tag=slug-generator-config

This creates config/slug-generator.php in your application.

Publish and run the slug history migration (optional)

Only required if you intend to use the HasSlugHistory trait.

php artisan vendor:publish --tag=slug-generator-migrations
php artisan migrate

Usage

Basic Usage

Add the HasSlug trait to any Eloquent model:

use Illuminate\Database\Eloquent\Model;
use PhilipRehberger\SlugGenerator\Concerns\HasSlug;

class Post extends Model
{
    use HasSlug;
}

The trait reads from the title column by default and writes to slug:

$post = Post::create(['title' => 'Hello World']);
echo $post->slug; // 'hello-world'

Duplicate slugs automatically receive a numeric suffix:

Post::create(['title' => 'Hello World']); // slug: 'hello-world'
Post::create(['title' => 'Hello World']); // slug: 'hello-world-2'

Per-Model Overrides

class Article extends Model
{
    use HasSlug;

    public function slugSource(): string|array  { return 'title'; }
    public function slugField(): string          { return 'slug'; }
    public function slugSeparator(): string      { return '-'; }
    public function slugMaxLength(): ?int        { return null; }
    public function slugShouldBeUnique(): bool   { return true; }
    public function slugUniqueScope(): ?string   { return null; }
    public function slugOnUpdate(): bool         { return false; }
}

Scoped Uniqueness

class Post extends Model
{
    use HasSlug;

    public function slugUniqueScope(): ?string
    {
        return 'category_id';
    }
}

Slug Template

Use a template pattern to control how attributes are combined in the slug:

class Author extends Model
{
    use HasSlug;

    public function slugTemplate(): ?string
    {
        return '{last_name}-{first_name}';
    }
}

$author = Author::create(['first_name' => 'John', 'last_name' => 'Doe']);
echo $author->slug; // 'doe-john'

Placeholders use the {attribute} syntax and are resolved from model attributes before slugification. Missing or null attributes are omitted from the result.

Slug History and Redirects

use PhilipRehberger\SlugGenerator\Concerns\HasSlug;
use PhilipRehberger\SlugGenerator\Concerns\HasSlugHistory;

class Post extends Model
{
    use HasSlug;
    use HasSlugHistory;

    public function slugOnUpdate(): bool { return true; }
}

Use findBySlugOrRedirect() in controllers to handle current and old slugs transparently:

public function show(string $slug): Response
{
    $result = Post::findBySlugOrRedirect($slug);

    if ($result === null) { abort(404); }

    if (is_array($result) && $result['redirect']) {
        return redirect(route('posts.show', $result['slug']), 301);
    }

    return view('posts.show', ['post' => $result]);
}
