我正在使用Micha的IPN。 error_log中没有任何内容，也没有数据库连接错误。 ipn返回无效。我使用了$ _REQUEST ['tid']所以我可以从URL中提取tid以匹配$ price与mc_gross。这段代码现在可以使用了！
表单代码
$pid = $_REQUEST['pid'];
$tid = $_REQUEST['tid'];
$choice = @mysql_query("SELECT *
FROM tourneys
WHERE tid = '". $_REQUEST['tid']."'");
if (!$choice) {
die('<p>Error retrieving tourney from database!<br />'.
'Error: ' . mysql_error(). '</p>');
}
while ($Tourney = mysql_fetch_array($choice)) {
$price = $Tourney['price'];
$tourney_name = $Tourney['tourney_name'];
}
echo $price; //dbg checking if it elevates
