Laravel Query Filter

Easily add dedicated filters based on request parameters. Originally came from a great tutorial on Laracasts. After copying it from project to project a few times I've now put it into a little package and added a generator for ease of use.

Installation

You can install the package via composer:

composer require ralphmorris/laravel-query-filter

Usage

To allow a model to be filterable, first add the FilterableTrait to your model.

use Illuminate\Database\Eloquent\Model;
use RalphMorris\LaravelQueryFilter\FilterableTrait;

class Post extends Model
{
    use FilterableTrait;
}

Then to create your filter class run the command below.

php artisan make:filter PostFilters

This will place the filter class under an App\Filters namespace if you are using the default namespace/directory structure. It should look like this.

namespace App\Filters;

use RalphMorris\LaravelQueryFilter\QueryFilter;

class PostFilters extends QueryFilter
{
    /**
     * Example
     * 
     * The request parameter key as the method name.
     * Passes the parameters value to the method 
     * so we can apply a filter to the query.
     * 
     * @param  mixed $param Value of the request parameter
     */
    public function example_request_param($param)
    {
        $this->builder->where('example_request_param', $param);
    }
}

If you wanted to add a filter on the title and author ID, you might do something like this.

namespace App\Filters;

use RalphMorris\LaravelQueryFilter\QueryFilter;

class PostFilters extends QueryFilter
{
    public function title($title)
    {
        $this->builder->where('title', 'like', "%{$title}%");
    }

    public function author($authorId)
    {
        $this->builder->where('author_id', $authorId);
    }
}

Finally to add the filters to your query apply filter() query scope in the FilterableTrait to your query and pass the PostFilters class through.

public function index(PostFilters $filters)
{
    $posts = Post::filter($filters)->get();
}
