i have same problem with paypal adaptive payments in my current project. i have given my
notify_url as http://mysite.com/payment-success. In this page, i simply coded
$request = $_POST;
mail('myid@myaccount', $request);
and then i sent the transaction result to my mail to view.
Note, here in my mail i can able to see the transaction results and if i insert into database, it is inserting but i cant see the transaction results in my page. Try sending to your mail the transaction results.

Create paypal_ipn.php file and place php code in it.
// Response from Paypal
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$value = preg_replace('/(.*[^%^0^D])(%0A)(.*)/i','${1}%0D%0A${3}',$value);// IPN fix
$req .= "&$key=$value";
}
// assign posted variables to local variables
$data['item_name'] = $_POST['item_name'];
$data['item_number'] = $_POST['item_number'];
$data['payment_status'] = $_POST['payment_status'];
$data['payment_amount'] = $_POST['mc_gross'];
$data['payment_currency'] = $_POST['mc_currency'];
$data['txn_id'] = $_POST['txn_id'];
$data['receiver_email'] = $_POST['receiver_email'];
$data['payer_email'] = $_POST['payer_email'];
$data['custom'] = $_POST['custom'];
$data['invoice'] = $_POST['invoice'];
$data['paypallog'] = $req;
// post back to PayPal system to validate
$header = "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
////mail('atiftariq80@gmail.com','Step 9','Step 9');
$res = fgets ($fp, 1024);
if (true || strcmp($res, "VERIFIED") == 0) {
////mail('atiftariq80@gmail.com','PAYMENT VALID','PAYMENT VALID');
// Validate payment (Check unique txnid & correct price)
$valid_txnid = check_txnid($data['txn_id']);
$valid_price = check_price($data['payment_amount'], $data['item_number']);
// PAYMENT VALIDATED & VERIFIED!
if($valid_txnid && $valid_price){
//----------------- INSERT RECORDS TO DATABASE-------------------------------------
if ($data['invoice']=='basic') {
$price = 39;
} else {
$price = 159;
}
$this->user_model->update_user(
array(
'id' => $data['custom'],

$data2 = array('id' => '',

'mode ' => $data['payment_status'],
'paypal_log' => $data['paypallog'],
'user_id' => $data['custom'],
'created_at' => date('Y-m-d H:i:s',time())
);
$this->db->insert('tbl_paypal_log', $data2);
//----------------- INSERT RECORDS TO DATABASE-------------------------------------
}else{
// Payment made but data has been changed
// E-mail admin or alert user
}
} elseif ($res=='INVALID') {
// PAYMENT INVALID & INVESTIGATE MANUALY!
// E-mail admin or alert user
////mail('atiftariq80@gmail.com','PAYMENT INVALID AND INVESTIGATE MANUALY','PAYMENT INVALID AND INVESTIGATE MANUALY');
}
}
fclose ($fp);

There is a really good guide to Instant Payment Notifications (IPN) and understanding how they work. This guide provides you the steps you need to have your notify_url working properly.
There are good code samples provided by Paypal that do the validation response for you, which is really nice. You can use these are the starting point for your own.
