Compatible with laravel >= 8.0

To install the package in your project you need to require it with composer.

$ composer require asciisd/referrals-laravel

First, you need to set the package configurations by publishing the config file to your project config directory.

To publish the referrals.php config file use the publish command:

$ php artisan vendor:publish

and from the providers list choose the ReferralsLaravelServiceProvider.

Next, inside your .env file, add the route you want the invited user to be redirected to.

referral_route='route_name'

By default, the invited user will be redirected to the registration page with route register.

If you plan to use cookies to save the referral token, by default, the cookie life-time is set to 24 hours. You can customize the cookie life-time by setting the referral_token_cookie_lifetime inside your .env file.

referral_token_cookie_lifetime=1440

To use the package in your project, simply use the Referrable trait in your users model.

class User extends Authenticatable implements MustVerifyEmail{
     /*...*/
     use \Asciisd\ReferralsLaravel\app\Traits\Referrerable;
     /*...*/
 
}

Next, use php artisan migrate to migrate the database file. This migration wll create new table referrals. A one-to-many relationship is created with the users table.

The referrer_id is the id of the user who sent the invitation link.

For further usage of the referral token, you can use ReferralsLaravel middleware inside your Kernel.php file.

You can set and alias to your middleware to use it with specific routes:

protected $middlewareAliases = [
    /*...*/
    'referrals' => \Asciisd\ReferralsLaravel\app\Http\Middleware\ReferralsLaravel::class,
];

Or you can set it to any of your middleware groups:

protected $middlewareGroups = [
        'web' => [
            /*...*/
            \Asciisd\ReferralsLaravel\app\Http\Middleware\ReferralsLaravel::class,
        ],
        /*...*/
]

To get all user referrals user referrer relationship property along with user object.

foreach ($user->referrals as $referral)
{
    $referral->referral_token;
}

To get user referral details from the referrals table use the property referrals.

// Get authenticated referral token
auth()->user()->referral->referral_token;

To check if the user is invited by another user, use the isReferred() method on the user object.

// Return true if the user is invited
// and false if the user was not invited by other user.
$user->isReferred();

To check of the user has referral token or not use the hasReferralToken() method.

// Return true if the user has referral token, or false if not.
$user->hasReferralToken();

To generate user referral token, use the generateReferalToken() method. The method checks if the user has referral token or not, then it generated the referrals token.

$user->generateReferralToken();

To get the referral link you can either add referral_link attribute to the $append array inside User model and use it as user attribute,

protected $append = ['referral_link'];

Or, you can use the getReferralLink() method with the user object.

// Get the referral link with the user redirect route
// ex: https://mydomain.com/register?ref=34532234
$user->getReferralLink();

To get user referral token you can either add referral_token attribute to the $append array inside the User model and use it as attribute,

protected $append = ['referral_token'];

Or, you can use the getReferralToken() method with the user object.

$user->getReferralToken();

Add nova resource Referral will be automatically published during publishing the service provider, to use the package with Nova just add the Referral resource to NovaServiceProvider file to register it inside your nova.
