I am using PHP and using the PHP example from clickbank;
I am finding that the cverify variable never matches. Can any one help?
I am using PHP and using the PHP example from clickbank;
PHP Code:
function ipnVerification() {
$secretKey="YOUR SECRET KEY";
$pop = "";
$ipnFields = array();
foreach ($_POST as $key => $value) {
if ($key == "cverify") {
continue;
}
$ipnFields[] = $key;
}
sort($ipnFields);
foreach ($ipnFields as $field) {
// if Magic Quotes are enabled $_POST[$field] will need to be
// un-escaped before being appended to $pop
$pop = $pop . $_POST[$field] . "|";
}
$pop = $pop . $secretKey;
$calcedVerify = sha1(mb_convert_encoding($pop, "UTF-8"));
$calcedVerify = strtoupper(substr($calcedVerify,0,8));
return $calcedVerify == $_POST["cverify"];
}
