Laravel Vouchers π
This package can associate vouchers with your Eloquent models. This might come in handy, if you need to associate voucher codes with content that is stored in your Eloquent models.
Here is an example of how you can create vouchers and redeem them:
$videoCourse = VideoCourse::find(1);
$voucher = $videoCourse->createVoucher();
auth()->user()->redeemVoucher($voucher);Installation
You can install the package via composer:
composer require beyondcode/laravel-vouchersThe package will automatically register itself.
You can publish the migration with:
php artisan vendor:publish --provider="BeyondCode\Vouchers\VouchersServiceProvider" --tag="migrations"After the migration has been published you can create the vouchers table by running the migrations:
php artisan migrateYou can publish the config-file with:
php artisan vendor:publish --provider=BeyondCode\Vouchers\VouchersServiceProvider --tag="config"This is the contents of the published config file:
<?php
return [
/*
* Database table name that will be used in migration
*/
'table' => 'vouchers',
/*
* Database pivot table name for vouchers and users relation
*/
'relation_table' => 'user_voucher',
/*
* List of characters that will be used for voucher code generation.
*/
'characters' => '23456789ABCDEFGHJKLMNPQRSTUVWXYZ',
/*
* Voucher code prefix.
*
* Example: foo
* Generated Code: foo-AGXF-1NH8
*/
'prefix' => null,
/*
* Voucher code suffix.
*
* Example: foo
* Generated Code: AGXF-1NH8-foo
*/
'suffix' => null,
/*
* Code mask.
* All asterisks will be removed by random characters.
*/
'mask' => '****-****',
/*
* Separator to be used between prefix, code and suffix.
*/
'separator' => '-',
/*
* The user model that belongs to vouchers.
*/
'user_model' => \App\User::class,
];Usage
The basic concept of this package is that you can create vouchers, that are associated with a specific model. For example, you could have an application that sells online video courses and a voucher would give a user access to one specific video course.
Add the BeyondCode\Vouchers\Traits\HasVouchers trait to all your Eloquent models, that you want to be associated with vouchers.
In addition, add the BeyondCode\Vouchers\Traits\CanRedeemVouchers trait to your user model. This way users can easily redeem voucher codes and the package takes care of storing the voucher/user association in the database.
Creating Vouchers
Using the facade
You can create one or multiple vouchers by using the Vouchers facade:
$videoCourse = VideoCourse::find(1);
// Create 5 vouchers associated to the videoCourse model.
$vouchers = Vouchers::create($videoCourse, 5);The return value is an array containing all generated Voucher models.
The Voucher model has a property code which contains the generated voucher code.
Using the Eloquent model
In addition, you can also create vouchers by using the createVouchers method on the associated model:
$videoCourse = VideoCourse::find(1);
// Returns an array of Vouchers
$vouchers = $videoCourse->createVouchers(2);
// Returns a single Voucher model instance
$vouchers = $videoCourse->createVoucher();Vouchers with additional data
It might be useful to associate arbitrary data to your vouchers - maybe a personal message from the person that created the voucher, etc. When creating the vouchers, you can pass an array as the second argument, which you can then retrieve later on the Voucher instance.
$videoCourse = VideoCourse::find(1);
$vouchers = $videoCourse->createVouchers(2, [
'from' => 'Marcel',
'message' => 'This one is for you. I hope you like it'
]);
$voucher = $user->redeem('ABC-DEF');
$from = $voucher->data->get('from');
$message = $voucher->data->get('message');Vouchers with expiry dates
You can also create vouchers that will only be available until a certain date. A user can not redeem this code afterwards.
The createVouchers method accept a Carbon instance as a third parameter.
$videoCourse = VideoCourse::find(1);
$videoCourse->createVouchers(2, [], today()->addDays(7));Redeeming Vouchers
The easiest way to let your users redeem voucher codes is by using the redeemCode method on your User model:
$voucher = $user->redeemCode('ABCD-EFGH');If the voucher is valid, the method will return the voucher model associated with this code.
In case you want to redeem an existing Voucher model, you can use the redeemVoucher method on your User model:
$user->redeemVoucher($voucher);After a user successfully redeemed a voucher, this package will fire a BeyondCode\Vouchers\Events\VoucherRedeemed event. The event contains the user instance and the voucher instance.
You should listen to this event in order to perform the business logic of your application, when a user redeems a voucher.
Accessing the vouchers associated model
The Voucher model has a model relation, that will point to the associated Eloquent model:
$voucher = $user->redeemCode('ABCD-EFGH');
$videoCourse = $voucher->model;Handling Errors
The redeemCode and redeemVoucher methods throw a couple of exceptions that you will want to catch and react to in your application:
Voucher invalid
If a user tries to redeem an invalid code, the package will throw the following exception: BeyondCode\Vouchers\Exceptions\VoucherIsInvalid.
Voucher already redeemed
All generated vouchers can only be redeemed once. If a user tries to redeem a voucher for a second time, or if another user already redeemed this voucher, the package will throw the following exception: BeyondCode\Vouchers\Exceptions\VoucherAlreadyRedeemed::class.
Voucher expired
If a user tries to redeem an expired voucher code, the package will throw the following exception: BeyondCode\Vouchers\Exceptions\VoucherExpired.
