Paypal IPN: get Buyer address - paypal

Question

I have used the sandbox to get informations returned by Paypal IPN after a transaction.
The problem I have is that IPN doesn't send the buyer address information but I can still get his first name and his last name of the buyer for example.
I can get the transaction ID or item bought information without problem too. The only variables I can't get are all buyer address information like $_POST['address_name'] or $_POST['address_city'].
This is my HTML form:
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type='hidden' value="Montant_Achat" name="amount" />
<input name="currency_code" type="hidden" value="EUR" />
<input name="shipping" type="hidden" value="0.00" />
<input name="tax" type="hidden" value="0.00" />
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="XXXXXXX">
<p>
<input type="hidden" name="on0" value="Durée"><span id="texteDuree">Durée : </span><select id="duree" onchange="changeCustom()" name="os0">
<option value="1 mois" id="30">1 mois €0,01 EUR</option>
<option value="3 mois" id="90">3 mois €15,00 EUR</option>
<option value="6 mois" id="180">6 mois €30,00 EUR</option>
</select>
</p>
<input name="return" type="hidden" value="factures.php" />
<input name="cancel_return" type="hidden" value="paypal_pro.php" />
<input name="notify_url" type="hidden" value="paypal/paypal_notify.php" />
<input name="item_name" type="hidden" value="Nom de votre produit" />
<input name="no_note" type="hidden" value="1" />
<input name="lc" type="hidden" value="FR" />
<input name="bn" type="hidden" value="PP-BuyNowBF" />
<input id="custom" name="custom" type="hidden" value="<?php echo $_SESSION["numUser"]; ?>||30" />
<input type="hidden" name="currency_code" value="EUR">
<input type="hidden" name="no_shipping" value="2" />
<input type='hidden' name="address_override" value="1">

This is the beggining of my paypal notify file:
// lire le formulaire provenant du système PayPal et ajouter 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
// renvoyer au système PayPal pour validation
$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) {
$keyval = explode('=', $keyval);
if (count($keyval) == 2)
$myPost[$keyval[0]] = urldecode($keyval[1]);
}
$_req = 'cmd=_notify-validate';
foreach ($myPost as $key => $value) {
$value = urlencode(stripslashes($value));
$_req .= "&$key=$value";
}
// 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://ipnpb.paypal.com', 443, $errno, $errstr, 30);
// récupération des informations de paypal
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];
$custom = explode("||", $_POST['custom']);
$id_user = $custom[0];
$dureeContrat = $custom[1];
$first_name = $_POST["first_name"];
$last_name = $_POST["last_name"];
$address_city = $_POST["address_city"];
$address_country = $_POST["address_country"];
$address_country_code = $_POST["address_country_code"];
$address_name = $_POST["address_name"];
$address_state = $_POST["address_state"];
$address_street = $_POST["address_street"];
$address_zip = $_POST["address_zip"];
And this is the $POST variables returned by IPN:
Key: mc_gross
Key: protection_eligibility
Key: payer_id
Key: tax
Key: payment_date
Key: payment_status
Key: charset
Key: first_name
Key: option_selection1
Key: mc_fee
Key: notify_version
Key: custom
Key: payer_status
Key: business
Key: quantity
Key: verify_sign
Key: payer_email
Key: option_name1
Key: txn_id
Key: payment_type
Key: btn_id
Key: last_name
Key: receiver_email
Key: payment_fee
Key: shipping_discount
Key: insurance_amount
Key: receiver_id
Key: txn_type
Key: item_name
Key: discount
Key: mc_currency
Key: item_number
Key: residence_country
Key: handling_amount
Key: shipping_method
Key: transaction_subject
Key: payment_gross
Key: shipping
Key: ipn_track_id
Thank you in advance for your help.

Answer 1

PayPal will only send an address with the IPN notification if an address was included with the payment information. Otherwise, it leaves it out entirely.
If during the button creation process you specified that shipping was not required that would cause no shipping to be returned in IPN. Another possibility is that you don't have shipping required on the order so the buyer simply opts out of including their shipping address during checkout, in which case PayPal won't send it to you.
