This package allows you to easily handle database filtering through query strings. The idea is taken from one of the Jeffrey's videos (behind the paywall). One quick example might look like this: /users?filter-username=~joe
will result in SQL query select * from users where "username" like '%joe%'
.
You can install the package via composer:
composer require kyslik/laravel-filterable
Laravel will discover the package by itself. If you feel old-school, disable auto-discovery and add Kyslik\LaravelFilterable\FilterableServiceProvider::class
to the providers array in your config/app.php
.
You may continue by publishing configuration by issuing following artisan command php artisan vendor:publish
.
Package lets you to create && apply two kinds of filters custom and generic.
Custom filters are just like in Jeffrey's video. You define a logic on a builder instance and package applies it via local scope.
Let's say a product requires displaying recently created records. You create a method recent($minutes = null)
inside a filter class, which returns Builder instance:
public function recent($minutes = null): \Illuminate\Database\Eloquent\Builder
{
$minutes = (is_numeric($minutes)) ? $minutes : 30;
return $this->builder->where('created_at', '>=', Carbon\Carbon::now()->subMinutes($minutes));
}
Note: full example is shown later on
Generic filters are those defined in config file. By default, the package supports filtering timestamps
, ranges
, ins
, booleans
and strings
.
/?filter-created_at=t>=1510952444
/?filter-id=><1,19
/?filter-id=i=1,5,10,12
/?filter-admin=b=yes
/?filter-username=joe
/?filter-username=~joe
/?filter-username=~joe&filter-admin=b=yes&filter-created_at=t=1510952444

While using both custom or generic filters you must:
- have local scope on model with the signature
scopeFilter(Builder $query, FILTERNAME $filters)
- have particular (
FILTERNAME
) filter class that extends one of:Kyslik\LaravelFilterable\Generic\Filter
class - allows usage of both custom & generic filtersKyslik\LaravelFilterable\Filter
class - allows usage of only custom filters
- call a scope within a controller
You can use the following command to create a new filter.
php artisan make:filter SomeFilter
This will create a new Custom filter in the app/Filters directory. To create a Generic filter just add the --generic
(-g
) flag to the command:
php artisan make:filter SomeGenericFilter -g
Lastly, you can override the default namespace by changing the namespace config value e.g.
config/filterable.php
return [
'namespace' => 'Http\Filters',
...
];
Let's say you want to use filterable on User
model. You will have to create the filter class App/Filters/UserFilter.php
(php artisan make:filter UserFilter
), specify filterMap()
and filter method (recent(...)
) with the custom logic.
<?php
namespace App\Filters;
use Kyslik\LaravelFilterable\Filter;
class UserFilter extends Filter
{
public function filterMap(): array
{
return ['recent' => ['recently', 'recent']];
}
public function recent($minutes = null)
{
$minutes = (is_numeric($minutes)) ? $minutes : 30;
return $this->builder->where('created_at', '>=', \Carbon\Carbon::now()->subMinutes($minutes)->toDateTimeString());
}
}
Note:
filterMap()
shall return an associative array where key is a method name and value is either alias or array of aliases
Now add a local scope to the User
model via Filterable:
use Kyslik\LaravelFilterable\Filterable;
...
class User extends Model
{
use Filterable;
...
}
Finally, call the scope in a controller like so:
use App\Filters\UserFilter;
...
public function index(User $user, UserFilter $filters)
{
return $user->filter($filters)->paginate();
}
Now end-user can visit users?recent
or users?recently
or users?recent=25
and results will be filtered by recent()
method defined in UserFilter
class.
Let's say you want to use generic filters on User
model. You will have to create filter class App/Filters/UserFilter.php
(php artisan make:filter UserFilter -g
) and specify $filterables
just like below:
<?php
namespace App\Filters;
use Kyslik\LaravelFilterable\Generic\Filter;
class UserFilter extends Filter
{
protected $filterables = ['id', 'username', 'email', 'created_at', 'updated_at'];
}
Next, you will have to add a local scope to the User
model via Filterable:
use Kyslik\LaravelFilterable\Filterable;
...
class User extends Model
{
use Filterable;
...
}
Finally, call the scope in a controller like so:
use App\Filters\UserFilter;
...
public function index(User $user, UserFilter $filters)
{
return $user->filter($filters)->paginate();
}
Now you are ready to filter User
model.
Note: behind the scenes
...\Generic\Filter
class extendsFilter
class, therefore using...\Generic\Filter
also enables you to apply custom filters defined within the filter class
While using generic filters you may define which generics should be allowed. Define settings()
method in a filter class, see below:
use Kyslik\LaravelFilterable\Generic\Filter
...
class UserFilter extends Filter
{
protected $filterables = ['id', 'username', 'email', 'created_at', 'updated_at'];
protected function settings()
{
// global settings for this filter, pick either "except" or "only" logic
$this->only(['=', '~', '!~']);
// $this->except(['!=']);
// settings applied only to some columns, these settings ignore the "global" settings above
$this->for(['username', 'id'])->only(['!=', '>=', '=', '~']);
$this->for(['id'])->only(['=', '!=', '~']); // settings for "id" will be re-written
}
}
In case you need to apply a filter when no filter is applied yet (determined by what query-string contains at the given request), you can use the following code in the controller:
public function index(User $user, UserFilter $filter)
{
// will redirect and "apply" the `recent` and `filter-id` filters
// if not a single filter from UserFilter is applied
$filter->default(['recent' => now()->toDateTimeString(), 'filter-id' => '!=5']);
return $user->filter($filter)->paginate();
}
End-user is going be redirected from http://filters.test/users
to http://filters.test/users?recent=2018-10-01 13:52:40&filter-id=!=5
.
In case the filter that you specify as default does not exist Kyslik\LaravelFilterable\Exceptions\InvalidArgumentException
is thrown.
Caution: be careful of infinite redirects
