PHP: PayPal payment API not returning result?

Question

I use the following code:

$enableSandbox = true;
$paypalConfig = [   'email' => 'test-facilitator@gmail.com',
                    'return_url' => 'http://test.com/paypal/?back',
                    'cancel_url' => 'http://test.com/paypal/?cancel',
                    'notify_url' => 'http://test.com/paypal/?notify'];

$paypalUrl = $enableSandbox ? 'https://www.sandbox.paypal.com/cgi-bin/webscr' : 'https://www.paypal.com/cgi-bin/webscr';
$itemName = 'Call';
$itemAmount = 5.00;

$data = [];
foreach ($_POST as $key => $value) {
    $data[$key] = stripslashes($value);
}

$data['business'] = $paypalConfig['email'];

$data['return'] = stripslashes($paypalConfig['return_url']);
$data['cancel_return'] = stripslashes($paypalConfig['cancel_url']);
$data['notify_url'] = stripslashes($paypalConfig['notify_url']);

$data['item_name'] = $itemName;
$data['amount'] = $itemAmount;
$data['currency_code'] = 'GBP';

$queryString = http_build_query($data);

header('location:' . $paypalUrl . '?' . $queryString);
exit();

But after use, I am redirected to paypal.com home, and I am not receiving any error messages:

I also tested test-buyer@gmail.com , but it does not work.

How can I solve this problem?

Please update your code

$paypalConfig = [   'email' => 'test-facilitator@gmail.com',
                    'return_url' => 'http://test.com/paypal/?back',
                    'cancel_url' => 'http://test.com/paypal/?cancel',
    // Added new line
                    'cmd' => '_xclick',
                    'notify_url' => 'http://test.com/paypal/?notify'];

After foreach loop add

Added new line

$data['cmd'] = $paypalConfig['cmd'];

Then try hope it will work.

Because you are missing : Buy Now buttons — <INPUT TYPE="hidden" name="cmd" value="_xclick">

Please manage this and send cmd in your form-builder, it should work. Please let me know if not work.
