README

This package makes it easy to sort and filter Eloquent queries via an associative array of options, usually from a FormRequest class.

Installation

Install the package via Composer:

composer require joggapp/laravel-query-filters

Usage

Defining a QueryFilter

Consider a Product model with category, name, and price fields.

We can apply sorting and filtering on these fields by defining a QueryFilter class. To create one, use the following command:

php artisan make:query-filter ProductQueryFilter

This command will create a new QueryFilter class in the App\QueryFilters directory.

Within this class, you can define the fields that can be sorted in ascending or descending order:

protected array $sortableFields = [
    'name',
    'price',
];

Specify the default sort and filtering options:

protected array $defaultFilters = [
    'sort_by' => 'price:asc,name:asc'
];

And define how a filter will be applied:

public function category(string|array $value)
{
    if (is_array($value)) {
        $query->whereIn('category', $value);
    } else {
        $query->where('category', $category);
    }
}

Using QueryFilter Methods

After defining the QueryFilter, it can be used to apply filter and sorting options:

use App\Model\Product;
use App\QueryFilters\ProductQueryFilter;

$filters = [
    'category' => 'Apparel',
    'sort_by' => 'price:asc,name:asc',
];

(new ProductQueryFilter())
    ->set($filters)
    ->apply(Product::query())
    ->get();

In this example, we are getting all products in the Apparel category sorted by price from low to high, then alphabetically by name.

SortBy Validation Rule

Included in this package is a SortBy validation rule that can be used to help validate sort-by parameters:

use App\Models\Product;
use App\QueryFilters\ProductQueryFilter;
use Illuminate\Support\Facades\Validator;
use JoggApp\LaravelQueryFilters\Rules\SortBy;

$data = [
    'sort_by' => 'price:asc,name:asc',
];

$validator = Validator::make($data, [
    'sort_by' => ['sometimes', new SortBy()],
]);

$validated = $validator->validated();

$products = (new ProductQueryFilter())
    ->set($validated)
    ->apply(Product::query())
    ->get();
