User (signup) invitation package for laravel

larainvite is a laravel package, to allow existing users to invite others by email.

It generates referral code and keep track of status.

Installation

Begin by installing the package through Composer. Run the following command in your terminal:

composer require raymondwilkinson/larainvite

add the package service provider in the providers array in config/app.php:

Junaidnasir\Larainvite\LaraInviteServiceProvider::class

you may add the facade access in the aliases array:

'Invite'  => Junaidnasir\Larainvite\Facades\Invite::class

publish the migration and config file:

php artisan vendor:publish"

migrate to create user_invitation table

php artisan migrate

edit your User model to include larainviteTrait

use Junaidnasir\Larainvite\InviteTrait;
class user ... {
    use InviteTrait;
}

Usage

You can use facade accessor to retrieve the package controller. Examples:

$user = Auth::user();
//Invite::invite(EMAIL, REFERRAL_ID); 
$refCode = Invite::invite('email@address.com', $user->id);
//or 
//Invite::invite(EMAIL, REFERRAL_ID, EXPIRATION); 
$refCode = Invite::invite('email@address.com', $user->id, '2016-12-31 10:00:00');

now create routes with refCode, when user access that route you can use following methods

// Get route
$code = Request::input('code');
if( Invite::isValid($code))
{
    $invitation = Invite::get($code); //retrieve invitation modal
    $invited_email = $invitation->email;
    $referral_user = $invitation->user;

    // show signup form
} else {
    $status = Invite::status($code);
    // show error or show simple signup form
}

// Post route
$code = Request::input('code');
$email = Request::input('signup_email');
if( Invite::isAllowed($code,$email) ){
    // Register this user
    Invite::consume($code);
} else {
    // either refCode is inavalid, or provided email was not invited against this refCode
}

with help of new trait you have access to invitations sent by user

$user= User::find(1);
$invitations = $user->invitations;
$count = $user->invitations()->count();

Events

larainvite fires several events

• 'junaidnasir.larainvite.invited'
• 'junaidnasir.larainvite.consumed'
• 'junaidnasir.larainvite.canceled'
• 'junaidnasir.larainvite.expired'

all of these events incloses invitation modal so you can listen to these events. include listener in EventServiceProvider.php

protected $listen = [
    'junaidnasir.larainvite.invited' => [
        'App\Listeners\userInvite',
    ],
];

public function handle($invitation)
{
    \Mail::queue('invitations.emailBody', $invitation, function ($m) use ($invitation) {
            $m->from('From Address', 'Your App Name');
            $m->to($invitation->email);
            $m->subject("You have been invited by ". $invitation->user->name);
