Not receive response from paypal on success - php

Question

I have integrate paypal with my Laravel application. I'm able to make payment successfully from Paypal, but after successful payment I'm not able to receive any type of response in my site.
My code is as below:
public function aCoolFunction(CreateDistrictRequest $request)
{
$data = $request->only('city_id', 'name', 'latitude', 'longitude');
$district = $this->districtRepository->create($data);
$payment = 'sandbox';
$values = [
'charest' => 'utf-8',
'lc' => 'US',
'cmd' => '_xclick',
'amount' => $product->price, // PRICE
'business' => 'test-facilitator#gmail.com', // PAYPAL EMAIL
'item_name' => $product->name, // NAME
'item_number' => $product->id, // ITEM ID
'currency_code' => 'USD',
'no_note' => '0',
'tax_rate' => 0, // 0- TO NOT ADD ANY FEES
'no_shipping' => 1, // NO ADDRESS
'rm' => '1',
'page_style' => 'paypal',
'custom' => '1', // ANY VALUES TO RETURN IT AFTER PAYMENT SUCCESS
'return' => url('payment-status'), // RETURN - MUST BE A VALID URL
'cancel_return' => url('payment-cancel'),
'notify_url' => url('payment-ipn') // IPN PAYPAL - CHECK IF IS PAID
];
$pay_url = "https://www.paypal.com/cgi-bin/webscr";
// CREATE $payment TO CHECK IF IS SANDBOX or LIVE - FROM CONFIG FILE FOR EXAMPLE
if ($payment == 'sandbox') :
$pay_url = "https://www.sandbox.paypal.com/cgi-bin/webscr";
endif;
return view('paypalpayment', ['pay_url' => $pay_url, 'values' => $values]);
}
public function paymentInfo(Request $request)
{
$myfile = fopen("paypalog.txt", "w") or die('Cannot open file: ' . $my_file);
$data = 'Transaction id = ' . $request;
fwrite($myfile, $data);
if ($request->tx)
{
if ($payment = Payment::where('transaction_id', $request->tx)->first())
{
$payment_id = $payment->id;
}
else
{
$payment = new Payment;
$payment->item_number = $request->item_number;
$payment->transaction_id = $request->tx;
$payment->currency_code = $request->cc;
$payment->payment_status = $request->st;
$payment->save();
$payment_id = $payment->id;
}
return 'Pyament has been done and your payment id is : ' . $payment_id;
}
else
{
return 'Payment has failed';
}
}
public function payment_success(Request $req)
{
$myfile = fopen("paypalog1.txt", "w") or die('Cannot open file: ' . $my_file);
$data = 'Transaction id = ' . $request->tx;
fwrite($myfile, $data);
}
from above code paymentinfo() is call in success or failure of payment from paypal. but here I'am not able to get any type of response from Paypal regarding payment.
This are my routes
Route::get('payment-status',array('as'=>'payment.status','uses'=>'PaymentController#paymentInfo'));
Route::get('payment',array('as'=>'payment','uses'=>'PaymentController#payment'));
Route::get('payment-cancel', function () {
return 'Payment has been canceled';
});
Route::get('payment-success' , 'PaymentController#payment_success');
Can anyone help me to solve this issue?

While dealing with PayPal you have to implement the IPN (Instant payment Notification) to get the status of the payment whether it is successful or failed.
For that you have to activate the IPN under the setting in your PayPal account and provide an url of your system to receive the IPN data, and that url must be of post type.
If I am not wrong, you have created this url for the same:
Route::get('payment-success' , 'PaymentController#payment_success');
but the issue is, it is of get type, so change it to 'post' and try again. If this url is not for the same purpose then create a url for the same.
P.S.: for testing purpose, PayPal provides an IPN simulator to test the same process, use that one it will be very helpful.
