This package should be used for a code-based verification of actions (typically routes).
Currently packages supports two channels for sending verification codes:
- sms
but it's easy to extend the package to support custom channels.
Packages ships also with a simple frontend (screen where user can input the code + default email/sms template) that could be easily overridden to meet your UX.
Package can help you also with a special case of a verification - the Two-factor authentication.
-
composer require brackets/verifications -
php artisan verifications:install
First of all, you need to have an authenticated user (i.e. User model) that implements Verifiable interface and use VerifiableTrait. You need to either define attribute/s email and/or phone on the model or implement accessor methods getPhoneAttribute()/getEmailAttribute().
Note: If you need to insert phone_number/email attributes to your user table, you can use artisan commands verifications:add-email {table-name} and/or verifications:add-phone {table-name}.
Then you need to define an action that would require verification.
This can be achieved in the configuration file /config/verifications.php.
'enabled' => env('VERIFICATION_ENABLED', true), // you can enable/disable globally (i.e. disabled for tests/dev env)
'actions' => [
'my-action' => [
'enabled' => true, // you can enable/disable single action
'channel' => 'sms', // currently: sms, email
'form_template' => 'brackets/verifications::verification', // blade name with namespace used for verification code form
'expires_in' => 15, // specifies how many minutes does it take to require another code verification for the same action
'expires_from' => 'verification', // one of: 'last-activity' or 'verification', specifies what triggers the expiration (see expires_in)
'code' => [
'type' => 'numeric', // specifies the type of verification code, can be one of: 'numeric' or 'string'
'length' => 6, // specifies the verification code length, defaults to 6
'expires_in' => 10, // specifies how many minutes is the code valid
]
]
]Typically you use this package to protect the entrance to some specific area of the application. This can be done by protecting all the routes using VerificationMiddleware middleware:
Route::middleware('verifications.verify:{my-action}')Example:
Let's say we want to verify the secret money-balance screen.
Define the action in your config:
'enabled' => env('VERIFICATION_ENABLED', true),
'actions' => [
'money-balance' => [
'enabled' => true,
'channel' => 'sms',
'form_template' => 'brackets/verifications::verification',
'expires_in' => 15,
'expires_from' => 'verification',
'code' => [
'type' => 'numeric',
'length' => 6,
'expires_in' => 10,
]
]
]And protect the route:
Route::get('/{account}/money-balance', 'MoneyController@moneyBalance')
->name('money-balance')
->middleware('verifications.verify:money-balance');When User tries to go to the /{account}/money-balance URL, he will be redirected to the verification screen where he is required to provide a code that was sent to him.
Verifying POST actions is a bit more tricky because user cannot be redirected back to the POST request (this is technically impossible).
Of course you can block the access to some POST action until user verifies it. Once he does verify it, everything works for him smoothly.
You should always create a GET route displaying a screen where User can perform the action and protect this GET route too (meaning protecting the entrance into the area, where he can perform the POST action). In that case, User never experience weird behaviour of needing to click to the same action twice.
You have two options here:
- either make sure User is always verified on some GET route before he performs the POST action (so limit the entrance to some area, where he can perform the POST actions),
- or crete a pseudo-screen with with some handy JavaScript, that will auto-run the POST request on User's behalf on load, so he doesn't have to click twice
Which option to use depends on your exact use case. But typically, if the action requires User to input some data to the form, the showForm GET route should be always protected, etc.
Example:
Let's continue with our MoneyApp example, but now we want to protect the money-withdraw action.
The protection of a POST route is very similar:
Route::post('/{account}/money-withdraw', 'MoneyController@moneyWithdraw')
->name('money-withdraw')
->middleware('verifications.verify:money-withdraw');This will definitely prevent withdrawing the money for the unverified user. But it doesn't solve the redirect problem. Let's do it.
If we think about it, we actually want to protect the GET route for money withdraw feature, not only the final submit button.
So let's add a GET route:
Route::get('/{account}/money-withdraw', 'MoneyController@moneyWithdrawForm')
->name('money-withdraw-form')
->middleware('verifications.verify:money-withdraw');
Route::post('/{account}/money-withdraw', 'MoneyController@moneyWithdraw')
->name('money-withdraw')
->middleware('verifications.verify:money-withdraw');Method moneyWithdrawForm will display the blade view with the form that will perform the POST to /{account}/money-withdraw on submit. But User is verified ahead, in the GET route, so his UX will be smooth.
Tip: you can of course add middleware to the whole group of routes:
Route::middleware(['verifications.verify:money-balance'])->group(static function () {
Route::get('/{account}/money-balance', 'MoneyController@moneyBalance')
->name('money-balance');
Route::get('/{account}/money-withdraw', 'MoneyController@moneyWithdrawAutoConfirmator')
->name('money-withdraw-auto-confirmator');
Route::post('/{account}/money-withdraw', 'MoneyController@moneyWithdraw')
->name('money-withdraw');
// ...
});In some scenarios you may want to use the verification on some action and needs further customization (i.e. only verify if some other conditions are met or provide a custom redirectTo method for POST actions verifications). You may use the Verification facade to manually run the verification in your controller providing the closure that will be run only after successful verification:
public function postDownloadInvoice(Invoice $invoice)
{
// this code will run on the attempt before the verification and then again, after the successful verification
if (!$invoice->isPublished()) {
throw new InvoiceNotPublishedException();
}
return Verification::verify('download-invoice', // name of the action
'/invoices', // URL user will be redirect after verification (he must click to download the invoice again manually :(
function () use ($invoice) {
// on the other hand this code will run only once, after the verification
return $invoice->download();
});
}Note, that even in this scenario, you need to protect the GET route before the POST, otherwise User won't be able to be redirected to the verification prompt screen, he will not be able to proceed.
To customized the default blade views you just need to publish them using:
php artisan vendor:publish --provider="Brackets\Verifications\VerificationServiceProvider" --tag="views"In some cases, you may want to provide an option for your users to choose if they should verify some specific action. Or maybe you want to allow users with some specific role/permission to skip the verification for some specific action. In these cases you just need to define the strictly named method isVerificationRequired(string $action).
Example:
class User extends Authenticatable implements Verifiable
{
use VerifiableTrait;
// ...
public function isVerificationRequired($action) {
// allow super admin to all actions
if ($this->hasRole('Admin') {
return false;
}
if ($action == 'withdraw-money') {
// allow withdraw-money action to be optional (i.e. user can set it in their profile)
if (!$this->withdraw_monoey_requires_verification) {
return false;
}
}
return true;
}Special case for the use of this package is Two-Factor Authentication.
Imagine simple scenario when 2FA is required for all users.
First, add new 2FA action to the config:
'actions' => [
'2FA' => [
'enabled' => true,
'channel' => 'sms',
'expires_in' => 15,
'expires_from' => 'last_activity',
'code' => [
// ...
],
],
]And then protect all your routes:
Route::middleware([‘verifications.verify:2FA’])->group(function() {
// all your routes goes here
})The packages ships with two default channels - email and sms.
The package uses the default Laravel's Mail. facade to send emails, so be sure to configure it properly.
The package ships with the one SMS provider - Twilio.
To use Twilio, you just need to provide these variables in your .env file:
TWILIO_SID="INSERT YOUR TWILIO SID HERE"
TWILIO_AUTH_TOKEN="INSERT YOUR TWILIO TOKEN HERE"
TWILIO_NUMBER="INSERT YOUR TWILIO NUMBER IN [E.164] FORMAT"
Check out this blogpost to find out more info about the Twilio integration.
