Verify your users by call or SMS

PHPStan run-tests

It's a common practice: a user signs up, you send an SMS to their phone with a code, they enter that code in your application and they're off to the races.

This package makes it simple to add this capability to your Laravel application.

Installation

You can install the package via composer:

composer require worksome/verify-by-phone

You can publish the config file by running:

php artisan vendor:publish --tag="verify-by-phone-config"

Configuration

This package is built to support multiple verification services. The primary service is Twilio. You may configure the service in the config file at config/verify-by-phone.php under driver, or by using the dedicated .env variable: VERIFY_BY_PHONE_DRIVER.

twilio

To use our Twilio integration, you'll need to provide an account_sid, auth_token and verify_sid. All of these can be set in the config/verify-by-phone.php file under services.twilio.

Usage

To use this package, you'll want to inject the \Worksome\VerifyByPhone\Contracts\PhoneVerificationService contract into your application. Let's imagine that you want to send the verification code in a controller method:

public function sendVerificationCode(Request $request, PhoneVerificationService $verificationService)
{
    // Send a verification code to the given number
    $verificationService->send(new PhoneNumber($request->input('phone')));
    
    return redirect(route('home'))->with('message', 'Verification code sent!');
}

It's as simple as that! Note that we are using \Propaganistas\LaravelPhone\PhoneNumber to safely parse numbers in different formats.

Now, when a user receives their verification code, you'll want to check that it is valid. Use the verify method for this:

public function verifyCode(Request $request, PhoneVerificationService $verificationService)
{
    // Verify the verification code for the given phone number
    $valid = $verificationService->verify(
        new PhoneNumber($request->input('phone')), 
        $request->input('code')
    );
    
    if ($valid) {
        // Mark your user as valid
    }
}

The first parameter is the phone number (again using \Propaganistas\LaravelPhone\PhoneNumber), and the second is the verification code provided by the user.

Validation rule

We offer a rule to make it easy to verify a verification code during validation.

Be aware that this rule will call the verify method of the PhoneVerificationService contract, and likely will make an HTTP request.

Validator::validate($request->all(), [
    'phone_number' => ['required'],
    'verification_code' => ['required', Rule::verificationCodeIsValid('phone_number')],
]);

If your data doesn't include the phone number, you may instead pass it in manually:

Validator::validate($request->all(), [
    'verification_code' => ['required', Rule::verificationCodeIsValid('+441174960123')],
]);

We extend the Rule class for visual consistency with other rules, but you can also use the VerificationCodeIsValid rule directly for better IDE support:

Validator::validate($request->all(), [
    'verification_code' => ['required', new VerificationCodeIsValid('+441174960123')],
]);

This rule will also handle the case where the verification code has expired and return a suitable error message.

Artisan commands

This package ships with a couple of artisan commands that allow you to send and verify verification codes.

# Send a verication code to the given phone number
php artisan verify-by-phone:send "+441174960123"

# Check that a given verication code is valid for the given phone number
php artisan verify-by-phone:verify "+441174960123" 1234

The verify command will return a console failure if verification fails.

Testing

When writing tests, you likely do not want to make real requests to services such as Twilio. To support testing, we provide a FakeVerificationService that can be used to mock the verification service. To use it, you should set an env variable in your phpunit.xml with the following value:

<env name='VERIFY_BY_PHONE_DRIVER' value='null'/>

Alternatively, you may manually swap out the integration in your test via using the swap method. The fake implementation has some useful testing methods you can use:

it('tests something to do with SMS verification', function () {
    $service = new FakeVerificationService();
    $this->swap(PhoneVerificationService::class, $service);
   
    // Customise what happens when calling `send`
    $service->sendUsing(fn () => throw new Exception('Something went wrong'));
    
    // Customise what happens when calling `verify`
    $service->verifyUsing(fn () => throw new Exception('Something went wrong'));
    
    // Throw a VerificationCodeExpiredException
    $service->actAsThoughTheVerificationCodeExpired();
    
    // Assert that a verification was "sent" on the given number
    $service->assertSentVerification(new PhoneNumber('+441174960123'));
});

You may execute this project's tests by running:

composer test
