Laravel Eloquent Filter

This simple package helps you filter Eloquent data using query filters.

Installation

Run the following command:

$ composer require nahidulhasan/eloquent-filter

Getting started

Use the trait NahidulHasan\EloquentFilter\Filterable in your eloquent model.

Create a new class by extending the class NahidulHasan\EloquentFilter\QueryFilters and define your custom filters as methods with one argument. Where function names are the filter argument name and the arguments are the value.

Let’s assume you want to allow to filter articles data. Please see the following code.

<?php  
namespace App\Models;
use Illuminate\Database\Eloquent\Model;  
use NahidulHasan\EloquentFilter\Filterable;  
class Article extends Model  
{  
    use Filterable; 
    /*
    * The attributes that are mass assignable. 
    *  @var array 
    */ 
    protected $fillable = ['title', 'body'];
}

Create ArticleFilter class extending QueryFilters.

<?php
namespace App\Filters;  
use Illuminate\Database\Eloquent\Builder;  
use NahidulHasan\EloquentFilter\QueryFilters;  
class ArticleFilters extends QueryFilters  
{  
      /*  
    * Filter by Title. 
    * @param $title 
    * @return Builder 
    * @internal param $name 
    * @internal param string $level 
    */ 
    public function title($title) { 
        return $this->builder->where('title', 'like', '%' .$title.'%'); 
    }
}

With this class we can use the http query string : title=article_name or any combination of these filters. It is up to you to define if you will use AND wheres or OR.

Now in the controller you can apply these filters like as described in below :

<?php
namespace App\Http\Controllers;  
use App\Filters\ArticleFilters;  
use App\Models\Article;  
use Illuminate\Http\Request;  
/**  
* Class ArticleController 
* @package App\Http\Controllers 
*/
class ArticleController extends Controller  
{  
    /* 
    * Display a listing of the resource. 
    *  @param ArticleFilters $filters 
    *  @return \Illuminate\Http\Response 
    *  @internal param Request $request 
    */ 
    public function index(ArticleFilters $filters) 
    {  
        $articles = Article::filter($filters)->paginate(5);  
        return view('articles.index', compact('articles'))->with('i', (request()->input('page', 1) - 1) * 5); 
    }
}
