Laravel Query Filter

Laravel query filter provides an elegant way to filter resources via request query string. You can specify conditions in query string to filter eloquent models and resources.

Installation & Usage

Install via composer:

composer require omalizadeh/laravel-query-filter

Make a filter class:

php artisan make:filter FilterClassName

Add trait in model:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\HasMany;
use Illuminate\Database\Eloquent\Relations\HasOne;
use Omalizadeh\QueryFilter\Traits\HasFilter;

class User extends Model
{
    use HasFilter;

    public function profile(): HasOne
    {
        return $this->hasOne(Profile::class);
    }

    public function posts(): HasMany
    {
        return $this->hasMany(Post::class);
    }
}

Set filterable attributes, relations and other options in filter class:

<?php

namespace App\Filters;

use Omalizadeh\QueryFilter\ModelFilter;

class UserFilter extends ModelFilter
{
    protected function selectableAttributes(): array
    {
        return [
            'id',
            'phone'
        ];
    }

    protected function sortableAttributes(): array
    {
        return [
            'id',
            'created_at',
            'updated_at'
        ];
    }

    protected function summableAttributes(): array
    {
        return [
            'views'
        ];
    }

    protected function filterableAttributes(): array
    {
        return [
            'id',
            'phone',
            'is_active'
        ];
    }

    protected function filterableRelations(): array
    {
        return [
            'profile' => [
                'gender',
                'first_name'
            ],
            'posts' => [
                'post_body' => 'body'
            ]
        ];
    }

    protected function loadableRelations(): array
    {
        return [
            'profile'
        ];
    }
}

Filtering resources via json formatted filter parameter with pagination & sort sent as q in query string:

api/users?q={
    "page": {
        "limit": 20,
        "offset": 0
    },
    "sorts": [
        {
            "field": "id",
            "dir": "desc"
        }
    ],
    "filters": [
        [
            {
                "field": "is_active",
                "op": "=",
                "value": true
            }
        ]
    ],
    "sums": ["views"],
    "withs": ["profile"]
}

In Controller:

public function index(UserFilter $userFilter)
{
    $userFilterResult = User::filter($userFilter);
    
    // total resources count based on filters
    $count = $userFilterResult->count();
    
    // total sum of given attributes in filter if there is any
    $sums = $userFilterResult->sums();
    
    // Get query results as collection (paginated if there is pagination in filters)
    $users = $userFilterResult->data();
    
    // do stuff and return response
}

Available Operators

Operators	Value	Description
=	string/numeric/bool	Field is equal to value
!=	string/numeric/bool	Field is not equal to value
<>	string/numeric/bool	Field is not equal to value
>	string/numeric	Field is greater than value
>=	string/numeric	Field is greater than or equal to value
<	string/numeric	Field is lower than value
<=	string/numeric	Field is lower than or equal to value
like	string	Field is like string value
not like	string	Field is not like string
in	array	Field value is in given array
not	null/array	Field is not null (for null value)/ Not in given array
is	null	Field is null

Query String Format

Example conditions:

(`is_active` = 1 OR `phone` like "%912%") AND (`first_name` like "%omid%")

Then json filter will be:

{
    "page": {
        "limit": 20,
        "offset": 0
    },
    "sorts": [
        {
            "field": "id",
            "dir": "desc"
        }
    ],
    "filters": [
        [
            {
                "field": "is_active",
                "op": "=",
                "value": 1
            },
            {
                "field": "phone",
                "op": "like",
                "value": "912"
            }
        ],
        [
            {
                "field": "first_name",
                "op": "like",
                "value": "omid",
                "has": true
            }
        ]
    ]
}
