Laravel Query filter package

A simple package for adding your query filter files to project.

Introduction

Install the package with composer using the following command:

composer require milito/query-filter

Usage

For create new query filter you can run this command in your terminal:

php artisan make:query-filter {your-query-filter-name}

Example:

php artisan make:query-filter ProductsFilter

This command will create a ProductsFilter.php file in app/Filters/ path.

This ProductsFilter class, is extended from QueryFilter class, and it used for controller functions. And because of that, constructor of this class requires a request object.

But if you want to create a filter class with a simple array input, you need to use -a|--array option after your class name.

php artisan make:query-filter ProductsFilter -a

This ProductsFilter class, is extended from ArrayQueryFilter.

Namespace

You can add namespace to your file:

php artisan make:query-filter Products/ProductsFilter

The above will create a Products directory inside the app/Filters directory.

How to use!

After file generated you should add your functions.
Example:

<?php

namespace App\Filters;

use Milito\QueryFilter;

class ProductsFilter extends QueryFilter
{
   public function name($name = null)
   {
      if (!$name)
        return $this->builder;
      return $this->builder->where('name' , 'LIKE' , $name);
   }
}

HINT: If your function parameters don't have default values, you need to fill with value every time you want to use it.

Then you need to add QueryFilterScope to your model.
Example :

<?php
namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Milito\QueryFilterScope;

class Product extends Model{
    use QueryFilterScope;
}

Now you can use in your controller :

<?php

namespace App\Controllers;

use App\Filters\ProductsFilter;
use App\Models\Product;
class ProductsController extends Controller
{
    public function index(ProductsFilter $filter)
    {
       $products = Product::filter($filter)->paginate(20);

       return $products;
    }
}

or :

<?php

namespace App\Controllers;

use App\Filters\ProductsFilter;
use App\Models\Product;
use Illuminate\Http\Request;

class ProductsController extends Controller
{
    public function index(Request $request)
    {
       $filter = new ProductsFilter($request);

       $products = Product::filter($filter)->paginate(20);

       return $products;
    }
}

You can use request() function to get request from filter if you need request.
Example:

//...

  public function index(ProductsFilter $filter)
  {
     $request = $filter->request();

     $products = Product::filter($filter)->paginate($request->per_page??20);

     return $products;
  }

//...

To use a class that inherits from ArrayQueryFilter:

//...

  public function index(Request $request)
  {
     $filter = new ProductsFilter(["name" => $request->query("your_name_field")]);

     $products = Product::filter($filter)->paginate(20);

     return $products;
  }

//...
