Filterable is a Laravel package designed to simplify dynamic filtering and searching across models and their relationships, eliminating the need for repetitive query code. It provides an easy-to-use trait and macros for building powerful, dynamic query filters.

1. Require the package via Composer:

   composer require kalimeromk/filterable

2. The package supports auto-discovery, so no manual registration of the service provider is needed. However, if you are using an older Laravel version, add the service provider to your config/app.php:

   'providers' => [
       Kalimeromk\Filterable\PackageServiceProvider::class,
   ];

The whereLike macro allows you to perform "LIKE" searches on multiple fields, including related model fields.

use App\Models\User;

$users = User::query()
    ->whereLike(['name', 'email'], 'John')
    ->get();

This will return all users where the name or email fields contain the string "John".

$users = User::query()
    ->whereLike(['posts.title', 'posts.content'], 'Laravel')
    ->with('posts')
    ->get();

This will return all users who have posts with a title or content containing the string "Laravel".

The Filterable trait allows you to dynamically filter a model based on specific criteria, including LIKE queries, boolean fields, and whereIn filters, as well as range filters like _min and _max.

Add the Filterable trait to your model:

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Kalimeromk\Filterable\Traits\Filterable;

class User extends Model
{
    use Filterable;

    protected $fillable = ['name', 'email', 'is_active'];

    // Define fields for specific filters
    protected $boolFields = ['is_active'];
    protected $likeFields = ['name', 'email'];
}

use App\Models\User;
use Illuminate\Http\Request;

class UserController extends Controller
{
    public function index(Request $request)
    {
        $filters = $request->only(['name', 'email', 'is_active', 'age_min', 'age_max']);

        $users = User::filter($filters)->get();

        return response()->json($users);
    }
}

• Request:

  GET /users?name=Jane&is_active=true&age_min=25&age_max=35
  

• Result: Returns all active users (is_active = true) whose name contains "Jane" and whose age is between 25 and 35.
