Certainly! If you want to handle a sales funnel as an "asynchronous pipeline" in Laravel, where some steps require user interaction (e.g., payment) and others should run automatically after a trigger, you’ll typically want to combine pipelines with event-driven, queued, and/or state-machine approaches. Here’s how you can approach this:
1. Use jobs for asynchronicity
Each pipeline step can be represented as a queued job. After each important action, you dispatch the next job or wait for a user action.
Step 1: Reserve Stock (User Action)
This is triggered by the user clicking a button. In your controller:
public function reserveStock(Request $request)
{
$cart = $request->user()->cart;
// Reserve stock (could also be a job)
app(ReserveStock::class)->handle($cart);
// Automatically create order
CreateOrder::dispatch($cart);
return response()->json(['message' => 'Stock reserved, order created']);
}
Step 2: Create Order (Automatic, Queued Job)
class CreateOrder implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
public $cart;
public function __construct($cart)
{
$this->cart = $cart;
}
public function handle()
{
// Create order logic
$order = ...;
// Next: wait for user action to pay
// (No auto-dispatch here)
}
}
Step 3: PayOrder (Wait for User Action)
User is redirected to payment. Once payment succeeds (via webhook, controller callback, etc):
public function handlePaymentSuccess(Order $order)
{
// Payment succeeded.
CommitStock::dispatch($order);
return response()->json(['message' => 'Payment successful, order processing']);
}
Step 4: Commit Stock, Clear Cart, Notify (Chained Queued Jobs)
CommitStock
class CommitStock implements ShouldQueue
{
public $order;
public function __construct($order) { $this->order = $order; }
public function handle()
{
// Commit stock logic...
// Next: clear cart
ClearCart::dispatch($this->order);
}
}
ClearCart
class ClearCart implements ShouldQueue
{
public $order;
public function __construct($order) { $this->order = $order; }
public function handle()
{
// Clear cart logic...
// Next: notify customer
NotifyOrderConfirmation::dispatch($this->order);
}
}
NotifyOrderConfirmation
class NotifyOrderConfirmation implements ShouldQueue
{
public $order;
public function __construct($order) { $this->order = $order; }
public function handle()
{
// Send order confirmation email, etc.
}
}
2. (Optional) Use State Machine or Status Columns
Track order/cart status (status field: reserved, ordered, pending_payment, paid, committed, etc). Logic can branch based on status.
3. Short summary
Don't try to run all pipeline stages in a sequence if some depend on user actions. Instead, break the process into these steps, chaining them with jobs and invoking each stage as its prerequisites are met (either by user or via job completion).
4. Resources
Key Takeaway
By breaking up your pipeline into individual queued jobs, dispatched in response to system events or user actions, you create an asynchronous pipeline that fits your requirements.
If you'd like a "formal pipeline" implementation, consider an orchestrator class to manage the step-by-step execution and state.
Let me know if you want an example using events instead of jobs, or a more advanced workflow!
