Build Ussd (Unstructured Supplementary Service Data) applications with laravel without breaking a sweat.
You can install the package via composer:
composer require sparors/laravel-ussd:^3.0-betaFor older version use
composer require sparors/laravel-ussd:^2.0Laravel Ussd provides zero configuration out of the box. To publish the config, run the vendor publish command:
php artisan vendor:publish --provider="Sparors\Ussd\UssdServiceProvider" --tag=ussd-configFor older version look here: V2 README
<?php
namespace App\Ussd\States;
use App\Ussd\Actions\TransferAccountAction;
use Sparors\Ussd\Attributes\Paginate;
use Sparors\Ussd\Attributes\Transition;
use Sparors\Ussd\Context;
use Sparors\Ussd\Contracts\State;
use Sparors\Ussd\Decisions\Equal;
use Sparors\Ussd\Decisions\Fallback;
use Sparors\Ussd\Decisions\In;
use Sparors\Ussd\Menu;
use Sparors\Ussd\Record;
use Sparors\Ussd\Traits\WithPagination;
#[Transition(to: TransferAccountAction::class, match: new Equal(1))]
#[Transition(to: TransferAmountState::class, match: new In(2, 3), callback: [self::class, 'setTransferType'])]
#[Transition(to: NewAccountNameState::class, match: new Equal(4))]
#[Transition(to: HelplineState::class, match: new Equal(5))]
#[Transition(to: InvalidInputState::class, match: new Fallback())]
#[Paginate(next: new Equal('#'), previous: new Equal('0'))]
class CustomerMenuState implements State
{
use WithPagination;
public function render(): Menu
{
return Menu::build()
->line('Banc')
->listing($this->getItems(), page: $this->currentPage(), perPage: $this->perPage())
->when($this->hasPreviousPage(), fn (Menu $menu) => $menu->line('0. Previous'))
->when($this->hasNextPage(), fn (Menu $menu) => $menu->line('#. Next'))
->text('Powered by Sparors');
}
public function setTransferType(Context $context, Record $record)
{
$transferType = '2' === $context->input() ? 'deposit' : 'withdraw';
$record->set('transfer_type', $transferType);
}
public function getItems(): array
{
return [
'Transfer',
'Deposit',
'Withdraw',
'New Account',
'Helpline',
];
}
public function perPage(): int
{
return 3;
}
}An example of a final state
<?php
namespace App\Ussd\States;
use Sparors\Ussd\Attributes\Terminate;
use Sparors\Ussd\Contracts\State;
use Sparors\Ussd\Menu;
use Sparors\Ussd\Record;
#[Terminate]
class GoodByeState implements State
{
public function render(Record $record): Menu
{
return Menu::build()->text('Bye bye ' . $record->get('name'));
}
}Due to some limitation with PHP 8.0, you can not pass class instance to attributes. So to overcome this limitation, you can pass an array with the full class path as the first element and the rest should be argument required. eg.
<?php
namespace App\Ussd\States;
use Sparors\Ussd\Attributes\Transition;
use Sparors\Ussd\Contracts\State;
use Sparors\Ussd\Menu;
#[Transition(MakePaymentAction::class, [Equal::class, 1])]
#[Transition(InvalidInputState::class, Fallback::class)]
class WelcomeState implements State
{
public function render(): Menu
{
return Menu::build()->text('Welcome');
}
}<?php
namespace App\Http\Controllers;
use App\Ussd\Actions\MenuAction;
use App\Ussd\Responses\AfricasTalkingResponse;
use App\Ussd\States\WouldYouLikeToContinueState;
use Illuminate\Http\Request;
use Sparors\Ussd\Context;
use Sparors\Ussd\ContinuingMode;
use Sparors\Ussd\Ussd;
class UssdController extends Controller
{
public function __invoke(Request $request)
{
$lastText = $request->input('text') ?? '';
if (strlen($lastText) > 0) {
$lastText = explode('*', $lastText);
$lastText = end($lastText);
}
return Ussd::build(
Context::create(
$request->input('sessionId'),
$request->input('phoneNumber'),
$lastText
)
->with(['phone_number' => $request->input('phoneNumber')])
)
->useInitialState(MenuAction::class)
->useContinuingState(ContinuingMode::CONFIRM, now()->addMinute(), WouldYouLikeToContinueState::class)
->useResponse(AfricasTalkingResponse::class)
->run();
}
}Use USSD action to conditional decide which state should be the next.
<?php
namespace App\Http\Ussd\Actions;
use Sparors\Ussd\Contracts\Action;
use App\Http\Ussd\States\PaymentSuccessState;
use App\Http\Ussd\States\PaymentErrorState;
class MakePayment extends Action
{
public function execute(Record $record): string
{
$response = Http::post('/payment', [
'phone_number' => $record->phoneNumber
]);
if ($response->ok()) {
return PaymentSuccessState::class;
}
return PaymentErrorState::class;
}
}You can use configurator to simplify repetitive parts of your application so they can be shared easily.
<?php
namespace App\Http\Ussd\Configurators;
use Sparors\Ussd\Contracts\Configurator;
class Nsano implements Configurator
{
public function configure(Ussd $ussd): void
{
$ussd->setResponse(function (string $message, int $terminating) {
return [
'USSDResp' => [
'action' => $termination ? 'prompt': 'input',
'menus' => '',
'title' => $message
]
];
});
}
}
?>You can easily test how your ussd application with our testing utilities
<?php
namespace App\Tests\Feature;
use Sparors\Ussd\Ussd;
final class UssdTest extends TestCase
{
public function test_ussd_runs()
{
Ussd::test(WelcomeState::class)
->additional(['network' => 'MTN', 'phone_number' => '123123123'])
->actingAs('isaac')
->start()
->assertSee('Welcome...')
->assertContextHas('network', 'MTN')
->assertContextHas('phone_number')
->assertContextMissing('name')
->input('1')
->assertSee('Now see the magic...')
->assertRecordHas('choice');
}
