Phase: 4 Make Order table.

Make a migration, modal, and Controller for an order using this command.

php artisan make:model Order -mcr

Adding the required models for this implementation.

app/Order.php



Phase: 5 Update migration table 


We already generated a new migration table for order, now add some columns.


increments('id');
            $table->integer('member_id');
            $table->integer('service_id');
            $table->string('money_history_id')->nullable();
            $table->float('amount')->unsigned()->nullable();
            $table->integer('payment_status')->unsigned()->default(0);
            $table->timestamps();
            $table->softDeletes();
        });
    }

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



Phase:8 Make new Migration table Service


Using this flowing command.


php artisan make:model Service -mcr



Now, add some columns in Service table.


increments('id');
            $table->string('name');
            $table->string('amount');
            $table->timestamps();
        });
    }

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



then use this flowing command to migrate this service table.


php artisan migrate



Phase: 9 Add helper 


Adding a new helper class for generating gateway object as well as routes to interact with PayPal API.


app/PayPal.php


setUsername(config('services.paypal.username'));
        $gateway->setPassword(config('services.paypal.password'));
        $gateway->setSignature(config('services.paypal.signature'));
        $gateway->setTestMode(config('services.paypal.sandbox'));

        return $gateway;
    }

    /**
     * @param array $arguments
     * @return mixed
     */
    public function purchase(array $arguments)
    {
        $response = $this->gateway()
            ->purchase($arguments)
            ->send();

        return $response;
    }

    /**
     * @param array $arguments
     */
    public function complete(array $arguments)
    {
        $response = $this->gateway()
            ->completePurchase($arguments)
            ->send();

        return $response;
    }

    /**
     * @param $amount
     */
    public function formatAmount($amount)
    {
        return number_format($amount, 2, '.', '');
    }

    /**
     * @param $supply
     */
    public function getCancelUrl($supply)
    {
        return route('paypal.checkout.cancelled', $supply->id);
    }

    /**
     * @param $supply
     */
    public function getReturnUrl($supply)
    {
        return route('paypal.checkout.completed', $supply->id);
    }

    /**
     * @param $supply
     */
    public function getNotifyUrl($supply)
    {
        $env = config('services.paypal.sandbox') ? "sandbox" : "live";

        return route('webhook.paypal.ipn', [$supply->id, $env]);
    }
}



Phase: 10 updates config/service.php


Laravel comes with a config file  config/service.php to be used with third-party API services. For this implementation add following credentials under the same file as below.


config/service.php


'paypal' => [
        'username' => env('PAYPAL_USERNAME'),
        'password' => env('PAYPAL_PASSWORD'),
        'signature' => env('PAYPAL_SIGNATURE'),
        'sandbox' => env('PAYPAL_SANDBOX'),
    ],



Phase:11 Make a new controller 


To Make a new controller use this flowing command.


php artisan make:controller PaymentGatewayController



update PaymentGatewayController.php 


member_id = 1 ;  //member id
        $supply->money_history_id = $money_history_id;
        $supply->service_id    = $service->id;
        $supply->amount    = $service->amount;
        $supply->save();

        // the above supply is just for example.
        return view('form', compact('service','money_history_id'));
    }

    /**
     * @param $supply_id
     * @param Request $request
     */
    public function checkout($money_history_id, Request $request)
    {
            $supply = Order::where('money_history_id', decrypt($money_history_id))->first();

            $paypal = new PayPal;

            $response = $paypal->purchase([
                'amount' => $paypal->formatAmount($supply->amount),
                'transactionId' => $supply->money_history_id,
                'currency' => 'USD',
                'cancelUrl' => $paypal->getCancelUrl($supply),
                'returnUrl' => $paypal->getReturnUrl($supply),
            ]);

            if ($response->isRedirect()) {
                $response->redirect();
            }

            return redirect()->back()->with([
                 'message' => $response->getMessage(),
                
            ]);
    }

    /**
     * @param $supply_id
     * @param Request $request
     * @return mixed
     */
    public function completed($supply_id, Request $request)
    {

        $supply = Order::findOrFail($supply_id);

        $paypal = new PayPal;

        $response = $paypal->complete([
            'amount' => $paypal->formatAmount($supply->amount),
            'transactionId' => $supply->money_history_id,
            'currency' => 'USD',
            'cancelUrl' => $paypal->getCancelUrl($supply),
            'returnUrl' => $paypal->getReturnUrl($supply),
            'notifyUrl' => $paypal->getNotifyUrl($supply),
        ]);

        if ($response->isSuccessful()) {
            $supply->update([
                'money_history_id' => $response->getTransactionReference(),
                'payment_status' => Order::PAYMENT_COMPLETED,
            ]);

            return redirect()->route('paymentCompleted', encrypt($supply_id))->with([
                'message' => 'You recent payment is sucessful with reference code ' . $response->getTransactionReference(),
            ]);
        }

        return redirect()->back()->with([
            'message' => $response->getMessage(),
        ]);

    }
    public function paymentCompleted($supply)
    {
        # code...
        return "Thanks! payment completed";
    }

    /**
     * @param $supply_id
     */
    public function cancelled($supply_id)
    {
        $supply = Order::findOrFail($supply_id);

        return redirect()->route('supply.paypal', encrypt($supply_id))->with([
            'message' => 'You have cancelled your recent PayPal payment !',
        ]);
    }

        /**
     * @param $supply_id
     * @param $env
     * @param Request $request
     */
    public function webhook($supply_id, $env, Request $request)
    {
        // to do with new release of sudiptpa/paypal-ipn v3.0 (under development)
    }
    
}



Phase:12 Make the view


An Last we Make two views one for send amount to Paypal as well as one for land after payment

@extends('layouts.app')

@section('content')
    

        

            

                @if(session()->has('message'))
                    

                        {{ session('message') }}
                    

                @endif
                

                    

                        laravel paypal integration
                    

                    

                        laravel paypal integration

                    {{ csrf_field() }}
