Introduction

In the ever-evolving landscape of web development, integrating secure and efficient payment gateways is crucial for any application, especially when it comes to e-commerce websites. Laravel, a powerful PHP framework, provides an excellent foundation for building robust web applications, and integrating the Stripe payment gateway into a Laravel project can significantly enhance the user experience. In this comprehensive guide, we'll walk you through the process of seamlessly integrating Stripe into your Laravel application.

Setup your stripe payment gateway

Before diving into the integration process, ensure you have a valid Stripe account. Head over to the Stripe website and sign up or log in to your existing account. Once logged in, navigate to the dashboard, where you'll find essential information such as your API keys, which we'll use in the integration process.

Step1: First install laravel 

composer create-project --prefer-dist laravel/laravel your-project-name

Step2: Create the blade file in the resource/views

        </div>
    </section>

</html>

This is the blade code to book the appointment on two options first on cash on delivery and second on the stripe

Step3: Create and set up model and migration and controller to store the data of the appointment

php artisan make:model Booking -mcr

This command will create the model Booking and along with model it will create migration, controller and resource

now let set up migration

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     */
    public function up(): void
    {
        Schema::create('appointments', function (Blueprint $table) {
            $table->id();
            $table->string('name')->nullable();
            $table->string('email')->nullable();
            $table->string('phone')->nullable();
            $table->string('payment_method')->nullable();
            $table->json('payment')->nullable();
            $table->enum('payment_status')->default(0);
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        Schema::dropIfExists('appointments');
    }
};

Now let set up model and controller

App\Models\Booking.php

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Booking extends Model
{
    use HasFactory, SoftDeletes;

    protected $fillable = [
        'phone',
        'email',
        'payment',
        'amount',
        'payment_method',
        'payment_status',
        'order_id',
        'price'
    ];

    protected $casts = [
        'payment' => 'json'
    ];
}

Now controller 

App\Http\Controllers\BookingController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Carbon\Carbon;
use App\Models\Booking;



class BookingController extends Controller
{ 
public function createAppointment(Request $request)
    {

        $data = $this->validate($request ,[
            'name' => 'required|string|max:45',
            'order_id' => 'nullable|string|max:6',
            'email' => 'required|email:rfc,dns|max:45',
            'phone' => 'required|string|max:20',
            'payment' => 'nullable|json',
            'payment_status' => 'nullable|boolean',
            'payment_method' => 'nullable|string|max:50',
            'price'  => 'required|string|max:50'
        ]);

        $appointment = Appointment::create($data);

        Session::put('appointment',$appointment);

        if($appointment->payment_method == 'Stripe')
        {
            return redirect()->route('stripe');

        }else{
            Session::put('data',$appointment);

            return redirect()->route('thanks');
        }
    }
}

Step4: Now to work with razorpay payment gateway install the razorpay package

composer require stripe/stripe-php

Step5: Add the secret and site key in the .env file

STRIPE_KEY=pk_test_xxxxxx
STRIPE_SECRET=sk_test_xxxxxx

config/services.php

'stripe' => [
     'secret' => env('STRIPE_SECRET'),
],

Step6: Create a blade to send the user to the payment page after successfully creating of the appointment stripe.blade.php

    });
</script>

now when the user will click on the pay now button payment of the amount will be visible and user can proceed to payment

Now after the payment has been done we have to save the response like the transaction id methods and many details which stripe send us as a response so to save that thing in the table we have to update the table by matching the order_id as it is unique in the table you can use id too but using order_id is better and proffectional so use it.

Step7:  Now make controller StripePaymentController

php artisan make:controller StripePaymentController

Now add this code in the controller

<?php

namespace App\Http\Controllers\payment;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Stripe;
use Session;
use App\Models\Setting;
use App\Models\Appointment;

class StripeController extends Controller
{
    public function index()
    {
        $appointment = Session::get('appointment');

        Session::put('appointment',$appointment);

        return view('stripe',compact('appointment'));
    }

    public function store(Request $request, Appointment $appointment)
    {
        $app = Session::get('appointment');
        $sett = Setting::first();

        Stripe\Stripe::setApiKey(env('STRIPE_SECRET'));
        try {
            $charge = Stripe\Charge::create([
                "amount" => $app->amount * 100,
                "currency" => $sett->payment_gateway['currency'],
                "source" => $request->stripeToken,
                "description" => "This payment is testing purpose of astrology",
            ]);

            $chargeJson = $charge->jsonSerialize();

            $orderId = $app->order_id;
            $data = Appointment::where('order_id',$orderId)->firstOrFail();

            $data->payment_status = 1;
            $data->payment = $chargeJson;

            $data->save();

            // return response()->json(['message' => 'Payment successful', 'charge' => $chargeJson]);
        } catch (\Exception $e) {
            // Handle any exceptions, log errors, and return an error response
            return response()->json(['error' => $e->getMessage()], 500);
        }

        Session::put('data', $data);
        return redirect()->route('thanks');
    }
}

Now create a route

Route::get('stripe', [StripeController::class, 'index'])->name('stripe');
Route::post('stripe', [StripeController::class, 'store'])->name('stripe.post');

Here in the index method we are getting the appointment details after creating the appointment through session and pass that details in the strip.blade.php

In store method we are getting the appointment details throught session form the index method 
now in the try there is $charge where we are passing the required details and after passing the details we are jsonSerialize() function to convert the response in the json format and after  that we are matching the order id with the session order id if the condition is true we are updating the appointment table like updating the payment status to 1 after the successfull payment and storing the response in the payment column in the table  $jsonCharges contain the response so we are saving the response in the payment column
