README

Filter Eloquent models using URL query parameters or HTTP QUERY request bodies.

Installation

Requires PHP 8.2+ and Laravel 11, 12 or 13.

composer require goodcat/laravel-eloquent-querystring

Quick Start

Add UseQueryString to your model and define a public filter method:

use Goodcat\QueryString\Attributes\QueryString;
use Goodcat\QueryString\Traits\UseQueryString;
use Illuminate\Database\Eloquent\Builder;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use UseQueryString;

    #[QueryString('email')]
    public function filterByEmail(Builder $query, string $email): void
    {
        $query->where('email', $email);
    }
}

Register a route in routes/api.php:

use App\Models\User;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;

Route::get('/users', function (Request $request) {
    return User::query()->queryString($request)->get();
});

Request /api/users?email=john%40doe.com to find users with that email. Parameters without a matching filter are ignored.

Filter Methods

Filters receive the builder, the value and, optionally, the parameter name. Use multiple names to share a filter:

#[QueryString('name', 'email')]
public function filterByText(Builder $query, string $value, string $name): void
{
    $query->where($name, 'like', $value.'%');
}

You can also repeat the attribute on a method. Validate input in your application before filtering.

Passing an Array

Pass an array to choose the filter values directly:

$users = User::query()->queryString(['email' => '[e-mail]'])->get();

Array values are passed as provided, without trimming or converting empty strings to null.

HTTP QUERY Requests

For QUERY, filters come only from the JSON or URL-encoded form body. URL parameters are ignored, even when the body is empty. Other methods, including POST, use only URL parameters.

Using the same imports as the Quick Start, register a route in routes/api.php:

Route::match(['QUERY'], '/users', function (Request $request) {
    return User::query()->queryString($request)->get();
});

Send a JSON body:

curl -X QUERY https://example.com/api/users \
    -H 'Content-Type: application/json' \
    -d '{"email":"[e-mail]"}'

Or a URL-encoded form body:

curl -X QUERY https://example.com/api/users \
    --data-urlencode 'email=[e-mail]'

Filter Objects

To keep filters in a separate class, override this public method on your model:

public function getQueryStringObject(): object
{
    return new UserFilters;
}

Define public methods on UserFilters with the same attributes and signatures as model filters.

Null Values

null values are ignored by default. To pass them to your filters, publish the configuration:

php artisan vendor:publish --provider="Goodcat\QueryString\QueryStringServiceProvider"

Set 'allows_null' => true in config/querystring.php and allow null in the relevant filter parameters.

Caching

Cache filters during deployment and regenerate the cache after changing models or filters:

php artisan querystring:cache

Clear it with php artisan querystring:clear. Laravel's optimize and optimize:clear commands also create and clear this cache.
