README

This service provides a flexible and reusable way to dynamically filter Eloquent queries in Laravel based on structured input. It supports filtering on direct model fields, nested relationships, date conditions, and more.

✨ Features

• Dynamic filters using field/operator/value structure
• Supports:
  • where
  • whereIn
  • whereDate
  • whereRelation
  • whereHas (with nested filters)
• Deep relationship filtering (e.g., author.owner.name)
• Extendable and clean structure

🤔 How to Use

Controller Example

use App\Models\Post;
use QueryFilter;
use Illuminate\Http\Request;

public function index(Request $request)
{
    $filters = $request->input('filters', []);

    $query = Post::query()->with(['author', 'author.owner']);

    $posts = (new QueryFilter())->apply($query, $filters)->paginate();

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

📂 Example Request Payload or you can set this from controller

{
  "filters": [
    { "field": "title", "operator": "like", "value": "laravel" },
    { "field": "category_id", "operator": "=", "value": 2 },
    { "field": "author.name", "operator": "like", "value": "john" },

🔧 Extending Support

You can enhance the logic further to include:

• != (not equal)
• not in
• Null checks
• Between queries

Just modify the applyCondition() method to suit your use case.
