How to Integrate Mollie Payment Gateway in Laravel 10 - Part 2

Category: Laravel
Updated on: 08 Nov, 2024
First, you have to install a fresh version of Laravel 10. You can go to the official documentation of Laravel:
You will see a section there: "Creating A Laravel Project". Here you will get your codes to install Laravel 10. I am going to write the commands you will need to install laravel. First, open your terminal where you want to install laravel on your computer. Then use these commands:
composer create-project laravel/laravel example-app
cd example-app
php artisan serve
You can run your application now using this url into your browser: http://127.0.0.1:8000
Now go to this location: resources > views > welcome.blade.php.

Change the codes of this page like this:
welcome.blade.php
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Laravel - Mollie Integration</title>
</head>
<body>

    <h2>Product: Laptop</h2>
    <h3>Price: $10</h3>
    <form action="{{ route('mollie') }}" method="post">
        @csrf
        <input type="hidden" name="product_name" value="Laptop">
        <input type="hidden" name="quantity" value="1">
        <input type="hidden" name="price" value="10.00">
        <button type="submit">Pay with Mollie</button>
    </form>
</body>
</html>
Create a migration file using this command:
php artisan make:migration create_payments_table
A migration file will be created in this location: "database > migrations > 2023_11_29_065611_create_payments_table.php"

Now write the following code here:
2023_11_29_065611_create_payments_table.php
<?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('payments', function (Blueprint $table) {
            $table->id();
            $table->string('payment_id');
            $table->string('product_name');
            $table->string('quantity');
            $table->string('amount');
            $table->string('currency');
            $table->string('payment_status');
            $table->string('payment_method');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        Schema::dropIfExists('payments');
    }
};
Write this command to create the "payments" table.
php artisan migrate
You have to create a model now. The model name will be the singular form of the table name. So it will be "Payment". Run this command in the terminal to create this model:
php artisan make:model Payment
I am going to create a controller now. So run this command in terminal:
php artisan make:controller MollieController
Modify the "route > web.php" file as this:
web.php
<?php

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

Route::get('/', function () {
    return view('welcome');
});

Route::post('mollie', [MollieController::class, 'mollie'])->name('mollie');
Route::get('success', [MollieController::class, 'success'])->name('success');
Route::get('cancel', [MollieController::class, 'cancel'])->name('cancel');
Install the laravel mollie package from here:
According to their instruction, now add this line in the .env file:
MOLLIE_KEY=test_VcfHCEkSxbstsDut6qJqTmsyAQr45T
MollieController.php
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Payment;
use Mollie\Laravel\Facades\Mollie;

class MollieController extends Controller
{
    public function mollie(Request $request)
    {
        $payment = Mollie::api()->payments->create([
            "amount" => [
                "currency" => "USD",
                "value" => $request->price // You must send the correct number of decimals, thus we enforce the use of strings
            ],
            "description" => $request->product_name,
            "redirectUrl" => route('success'),
            //"webhookUrl" => route('webhooks.mollie'),
            "metadata" => [
                "order_id" => time(),
            ],
        ]);

        //dd($payment);

        session()->put('paymentId', $payment->id);
        session()->put('quantity', $request->quantity);
    
        // redirect customer to Mollie checkout page
        return redirect($payment->getCheckoutUrl(), 303);
    }

    public function success(Request $request)
    {
        $paymentId = session()->get('paymentId');
        //dd($paymentId);
        $payment = Mollie::api()->payments->get($paymentId);
        //dd($payment);
        if($payment->isPaid())
        {
            $obj = new Payment();
            $obj->payment_id = $paymentId;
            $obj->product_name = $payment->description;
            $obj->quantity = session()->get('quantity');
            $obj->amount = $payment->amount->value;
            $obj->currency = $payment->amount->currency;
            $obj->payment_status = "Completed";
            $obj->payment_method = "Mollie";
            $obj->save();

            session()->forget('paymentId');
            session()->forget('quantity');

            echo 'Payment is successfull.';
        } else {
            return redirect()->route('cancel');
        }
    }

    public function cancel()
    {
        echo "Payment is cancelled.";
    }
}
