Get notified on stock unavailability

Enabling Guest Notification for Stock Unavailability

As a developer, I understand that you want to allow users (even guests) to sign up for notifications when an out-of-stock product becomes available again. Currently, your system requires visitors to log in or create an account before they can receive these alerts.

To implement this feature, we’ll modify the existing flow and introduce a new overlay form for guest users who want to subscribe to stock updates without logging in. Here’s how you can achieve this:

Step 1: Create a Guest Subscription Model

First, let’s create a separate model to store guest email addresses interested in receiving stock alerts.

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class GuestSubscription extends Model
{
    protected $table = 'guest_subscriptions';
    protected $fillable = ['product_id', 'email'];
}

We’re using the fillable property to specify that only product_id and email should be mass-assignable.

Step 2: Modify the Controller Method

Next, we need to update your stockAction() method in the ProductAlertController. Instead of redirecting to a login page when a guest tries to subscribe, we’ll display an overlay form. Here’s how you can modify the code:

public function stockAction(Request $request)
{
    if ($request->has('uenc')) {
        $actual_link = urldecode(base64_decode(strtr($request->input('uenc'), '-_,', '+/=')));
        $url_parts = parse_url($actual_link);
        parse_str($url_parts['query'], $params);
        $product_id = $params['product_id'];

        // Check if the user is logged in
        if (!auth()->check()) {
            return view('guest-subscribe')->with(['productId' => $product_id]);
        }

        // If logged in, save to database using the usual method here...
    }
}

In this updated version, when a guest visits /efk/productalert/add/stock, the system checks if they are already authenticated. If not, it returns a view called guest-subscribe and passes the product ID as a variable.

Step 3: Create the Guest Subscription View

Go ahead and create a new Blade template named guest-subscribe.blade.php. This will be the overlay that appears to guests:

<!-- resources/views/guest-subscribe.blade.php -->
<div class="overlay">
    <div class="modal-content">
        <h2>Subscribe for Stock Alerts</h2>
        <form action="{{ route('add.guest.subscribe', $productId) }}" method="post">
            @csrf
            <input type="email" name="email" placeholder="Enter your email address" required>
            <button type="submit">Subscribe</button>
        </form>
    </div>
</div>

This view contains a simple form with an email input field and a submit button. The form is posting to the add-guest-subscribe route, which we haven’t created yet.

Step 4: Create the Guest Subscription Route

In your routes file (typically routes/web.php), add this new route:

use App\Http\Controllers\ProductAlertController;
use Illuminate\Support\Facades\Route;

Route::post('guest-subscribe/{productId}', [ProductAlertController::class, 'addGuestSubscribe'])->name('add.guest.subscribe');

Step 5: Implement the Guest Subscription Method

Finally, add a new method to your ProductAlertController called addGuestSubscribe:

public function addGuestSubscribe(Request $request, int $productId)
{
    // Validate the form data (you can use Laravel's built-in validation or custom rules)
    $validatedData = $request->validate([
        'email' => 'required|email',
        'product_id' => 'required|integer'
    ]);

    // Ensure the product ID matches
    if ($validatedData['product_id'] != $productId) {
        return redirect()->back()->withErrors(['message' => 'Invalid product subscription.']);
    }

    // Create a new guest subscription record
    GuestSubscription::create($validatedData);

    return redirect()->back()->with('success', 'You have been subscribed to stock alerts for this product.');
}

This method validates the form data, checks if the provided product ID matches the expected one, and then creates a new GuestSubscription record in the database.

Conclusion

By following these steps, you’ll implement a “Notify me” feature that allows guests to subscribe to out-of-stock products without requiring them to log in or create an account. This change should significantly improve the user experience for your e-commerce platform while still allowing you to manage stock alerts effectively.

Remember that this is just one approach; depending on your specific requirements, you might need to add additional features like confirmation emails or a way for users to unsubscribe from these notifications. Always ensure that you’re handling user data responsibly and following best practices in security and privacy.
