Installation

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

composer require junaidnasir/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 --provider="Junaidnasir\Larainvite\LaraInviteServiceProvider"

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');
//or
//Invite::invite(EMAIL, REFERRAL_ID, EXPIRATION, BEFORE_SAVE_CALLBACK); 
$refCode = Invite::invite($to, Auth::user()->id, Carbon::now()->addYear(1),
                      function(/* InvitationModel, see Configurations */ $invitation) use ($someValue) {
      $invitation->someParam = $someValue;
});

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\Events\Invited
• Junaidnasir\Larainvite\Events\InvitationConsumed
• Junaidnasir\Larainvite\Events\InvitedCanceled
• Junaidnasir\Larainvite\Events\Expired

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

use Junaidnasir\Larainvite\Events\Invited;
use App\Listeners\SendUserInvitationNotification;

protected $listen = [
    Invited::class => [
        SendUserInvitationNotification::class,
    ],
];

userInvite.php

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);
        });
}
