Laravel Query Filter

A minimal approach to filtering eloquent models through query params

Installation

composer require baraveli/laravel-query-filters

Usage

Create custom filter class in your laravel application

In this case I have a filter for the user model. Every filter should extends the baraveli QueryFilter class. And the method name in each filter class correspond to the url param name so in this case when you call ?search="ssd" it is actually calling the search() method

<?php

namespace App\Filters;

use Illuminate\Database\Eloquent\Builder;
use Baraveli\QueryFilters\QueryFilter;

class UsersFilters extends QueryFilter
{        
    /**
     * per_Page
     *
     * @param  mixed $number
     * @return void
     */
    public function per_Page($number = 5)
    {
        return $this->builder->paginate($number);
    }

    /**
     * search
     *
     * @param  mixed $search
     * @return Builder
     */
    public function search($search) : Builder
    {
        return $this->builder->where('name','like', '%' . $search .'%');
    }

    
}

Add filterable trait to your eloquent model

Adding this trait will give you a filter() scope with in your laravel model that you can use to apply the previous query filter

<?php

namespace App\Models;

use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Baraveli\QueryFilters\Filterable;

class User extends Authenticatable
{
    use HasFactory, Notifiable, Filterable;
}

Response

Now with in your controller or route return and apply the filters

Route::get('users', function(UsersFilters $usersfilter){
    return User::filter($usersfilter)->get();
});

Now you will be able to use the query filters like so

• /api/users?search=Ms : Search all the users names
• /api/users?search=Ms&per_page=5 : Search all the users names and paginate the results
