use Illuminate\Http\Request;
use Validator;
use URL;
use Session;
use Redirect;
use Input;
use DB;

//All Paypal Details class
use PayPal\Rest\ApiContext;
use PayPal\Auth\OAuthTokenCredential;
use PayPal\Api\Amount;
use PayPal\Api\Details;
use PayPal\Api\Item;
use PayPal\Api\ItemList;
use PayPal\Api\Payer;
use PayPal\Api\Payment;
use PayPal\Api\RedirectUrls;
use PayPal\Api\ExecutePayment;
use PayPal\Api\PaymentExecution;
use PayPal\Api\Transaction;

class PaymentController extends Controller
    private $_api_context;
    public function __construct()
        //setup PayPal api context
        $paypal_conf = \Config::get('paypal');
        $this->_api_context = new ApiContext(new OAuthTokenCredential($paypal_conf['client_id'], $paypal_conf['secret']));

    public function addPayment()
        return view('addPayment');

    public function postPaymentWithpaypal(Request $request)
        $payer = new Payer();

    	$item_1 = new Item();

        $item_1->setName('Item 1') //item name
            ->setPrice($request->get('amount')); //unit price

        $item_list = new ItemList();

        $amount = new Amount();

        $transaction = new Transaction();
            ->setDescription('Your transaction description');

        $redirect_urls = new RedirectUrls();
        $redirect_urls->setReturnUrl(URL::route('status')) //Specify return URL

        $payment = new Payment();

        catch (\PayPal\Exception\PPConnectionException $ex) 
            if (\Config::get('app.debug')) 
                \Session::put('error','Connection timeout');
                return Redirect::route('paywithpaypal');
                \Session::put('error','Some error occur, sorry for inconvenient');
                return Redirect::route('paywithpaypal');

        foreach($payment->getLinks() as $link) 
            if($link->getRel() == 'approval_url') 
                $redirect_url = $link->getHref();

        // add payment ID to session
        Session::put('paypal_payment_id', $payment->getId());

            // redirect to paypal
            return Redirect::away($redirect_url);

        \Session::put('error','Unknown error occurred');
    	return Redirect::route('paywithpaypal');

    public function getPaymentStatus()
        // Get the payment ID before session clear
        $payment_id = Session::get('paypal_payment_id');

        // clear the session payment ID
        if (empty(Input::get('PayerID')) || empty(Input::get('token'))) 
            \Session::put('error','Payment failed');
            return Redirect::route('paywithpaypal');
        $payment = Payment::get($payment_id, $this->_api_context);

        $execution = new PaymentExecution();

        //---Execute the payment ---//
        $result = $payment->execute($execution, $this->_api_context);

        if ($result->getState() == 'approved') { 
            // Here Write your database logic like that insert record or value in database if you want 

            \Session::put('success','Payment success');
            return Redirect::route('paywithpaypal');
        \Session::put('error','Payment failed');

		return Redirect::route('paywithpaypal');

                <?php Session::forget('success');?>
                @if ($message = Session::get('error'))
                <div class="custom-alerts alert alert-danger fade in">
                    <button type="button" class="close" data-dismiss="alert" aria-hidden="true"></button>
                    {!! $message !!}
                <?php Session::forget('error');?>
                <div class="panel-heading text-center"><h2>paypal payment gateway in laravel 5</h2></div>
                <div class="panel-body">

                        {{ csrf_field() }}
                        <div class="form-group{{ $errors->has('amount') ? ' has-error' : '' }}">
                            <label for="amount" class="col-md-4 control-label">Enter Amount</label>
                            <div class="col-md-6">
                                <input id="amount" type="text" class="form-control" name="amount" value="{{ old('amount') }}" autofocus>
                                @if ($errors->has('amount'))
                                    <span class="help-block">
                                        <strong>{{ $errors->first('amount') }}</strong>
                        <div class="form-group">
                            <div class="col-md-6 col-md-offset-4">
                                <button type="submit" class="btn btn-primary">
