我正在構建會員區，並且使用avangate.com作爲付款系統。如何使用Avangate設置定期訂閱
我只想在發生週期性支付時更新數據庫中的訂戶日期和新的到期日期。
我得到這個IPN代碼從他們的出發點：
<?php
/* Internet Payment Notification */
$pass = "AABBCCDDEEFF"; /* pass to compute HASH */
$result = ""; /* string for compute HASH for received data */
$return = ""; /* string to compute HASH for return result */
$signature = $_POST["HASH"]; /* HASH received */
$body = "";
/* read info received */
ob_start();
while(list($key, $val) = each($_POST)){
$$key=$val;
/* get values */
if($key != "HASH"){
if(is_array($val)) $result .= ArrayExpand($val);
else{
$size = strlen(StripSlashes($val));
$result .= $size.StripSlashes($val);
}
}
}
$body = ob_get_contents();
ob_end_flush();
$date_return = date("YmdGis");
$return = strlen($_POST["IPN_PID"][0]).$_POST["IPN_PID"][0].strlen($_POST["IPN_PNAME"][0]).$_POST["IPN_PNAME"][0];
$return .= strlen($_POST["IPN_DATE"]).$_POST["IPN_DATE"].strlen($date_return).$date_return;
function ArrayExpand($array){
$retval = "";
for($i = 0; $i < sizeof($array); $i++){
$size = strlen(StripSlashes($array[$i]));
$retval .= $size.StripSlashes($array[$i]);
}
return $retval;
}
function hmac ($key, $data){
$b = 64; // byte length for md5
if (strlen($key) > $b) {
$key = pack("H*",md5($key));
}
$key = str_pad($key, $b, chr(0x00));
$ipad = str_pad('', $b, chr(0x36));
$opad = str_pad('', $b, chr(0x5c));
$k_ipad = $key^$ipad ;
$k_opad = $key^$opad;
return md5($k_opad . pack("H*",md5($k_ipad . $data)));
}
$hash = hmac($pass, $result); /* HASH for data received */
$body .= $result."\r\n\r\nHash: ".$hash."\r\n\r\nSignature: ".$signature."\r\n\r\nReturnSTR: ".$return;
if($hash == $signature){
echo "Verified OK!";
/* ePayment response */
$result_hash = hmac($pass, $return);
echo "<EPAYMENT>".$date_return."|".$result_hash."</EPAYMENT>";
/* Begin automated procedures (START YOUR CODE)*/
}else{

mail("[email protected]","BAD IPN Signature", $body,"");
