README

Invites provides a way to limit access to your Laravel applications by using invite codes.

Invite Codes:

• Can be available to anyone (great for sharing on social media).
• Can have a limited number of uses or unlimited.
• Can have an expiry date, or never expire.

Installation

You can pull in the package using composer:

$ composer require abstem/invites

Next, register the service provider with Laravel (no need on version 5.5):

// config/app.php
'providers' => [
    ...
    Abstem\Invites\InvitesServiceProvider::class,
];

And, register the facade:

// config/app.php
'aliases' => [
    ...
    'Invites'   =>  Abstem\Invites\Facades\Invites::class,
];

Finally, migrate the database:

$ php artisan migrate

Usage

Generate Invites

Make a single generic invite code with 1 redemption, and no expiry.

Invites::generate()->make();

Make 5 generic invite codes with 1 redemption each, and no expiry.

Invites::generate()->times(5)->make();

Make an invite with 10 redemptions and no expiry.

Invites::generate()->uses(10)->make();

Make an invite that expires on a specific date.

$date = Carbon::now('UTC')->addDays(7);
Invites::generate()->expiresOn($date)->make();

Make an invite that expires in 14 days.

Invites::generate()->expiresIn(14)->make();

Redeem Invites

You can redeem an invite by calling the redeem method. Providing the invite code and optionally an email address.

Invites::redeem('ABCDE');

If invites is able to redeem the invite code it will increment the number of redemptions by 1, otherwise it will throw an exception.

• InvalidInviteCode is thrown if the code does not exist in the database.
• ExpiredInviteCode is thrown if an expiry date is set and it is in the past.
• MaxUsesReached is thrown if the invite code has already been used the maximum number of times.

All of the above exceptions extend InvitesException so you can catch that exception if your application does not need to do anything specific for the above exceptions.

try {
    Invites::redeem(request()->get('code'), request()->get('email'));
} catch (InvitesException $e) {
    return response()->json(['error' => $e->getMessage()], 422);
}

Check Invites without redeeming them

You can check an invite by calling the check method. Providing the invite code and optionally an email address. (It has the same signature as the redeem method except it will return true or false instead of throwing an exception.

Invites::check('ABCDE');

Change Error Messages (and translation support)

In order to change the error message returned from invites, we need to publish the language files like so:

$ php artisan vendor:publish --tag=translations

The language files will then be in /resources/lang/vendor/invites/en where you can edit the messages.php file, and these messages will be used by invites. You can create support for other languages by creating extra folders with a messages.php file in the /resources/lang/vendor/invites directory such as de where you could place your German translations. Read the localisation docs for more info.

Config - change table name

First publish the package configuration:

$ php artisan vendor:publish --tag=config

In config/invites.php you will see:

return [
    'invite_table_name' => 'invites',
];

If you change the table name and then run your migrations Invites will then use the new table name.

Console

To remove used and expired invites you can use the cleanup command:

$ php artisan invites:cleanup
