In the previous post, I introduced a package that allowed you to filter for your Eloquent models in Laravel.As you can see here.

The latest version of this package is available in Github repository: v1.0.1

As I explained earlier,you may need to filter a model in your project like User model.For example, filtering users based on gender, age, online / offline status and etc... .

Now, you may check if the authenticated user actually has the authority to apply a given filter. For example, you may determine if a user has a premium account or is admin, can apply the StatusFilter to get listing the online or offline people.

Let's have a practical example below for a better understanding.

Setup EloquentBuilder package

In the first, if you have not Laravel,run below command:

$ composer create-project --prefer-dist laravel/laravel authorize-filter

Now go to root of the your application and install EloquentBuilder:

$ cd authorize-filter
$ composer require mohammad-fouladgar/eloquent-builder

Now, you should create a new directory in the ‍‍app directory as EloquentFilters.This directory is the storage place of the model filters.

Create Route and Controller

In this step, we need to create a Route for users listing.So open your routes/web.php file and add following route:

Route::get('users', 'UserController@index');

Then,you should create a controller named UserController:

Now you can open bellow url on your browser:


If you running this URL, users listing will be returned.
In the next step, we will implement the gender and status filters.

Gender Filter

At this point, we want to filter users based on gender.
First of all, you should create a new directory as User inside EloquentFilters.This directory contains user model filters.
Next, create a new file named GenderFilter.php:


after creating above filter, open your browser and run this url for apply filter on your query:


By running this url,users are listed who have the gender as male.


This filter has a authorize method.within method we want to check if a user has a premium account, can apply the StatusFilter to get listing the online or offline people.

Take a look at the following filter:


For apply the above filter,in browser open the below url:
