在您假设我没有建立数据库连接之前,我做到了。唯一不更新的代码部分是 if empty 语句。
所有值都可以正确回显,只是查询不起作用。
这是在目录配置中并命名为 stuff.php
$user = $mysqli->real_escape_string($_SESSION['username']);
$user_query = "SELECT * FROM users WHERE username = '$user'";
$result = $mysqli->query($user_query);
$row = $result->fetch_assoc();
$referrer = $row['ref'];
$refearn = $row['refearn'];
验证.php
include('config/stuff.php');
if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) { // Get Real IP
$IP = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
$IP = $_SERVER['REMOTE_ADDR'];
}
if ($IP=="external server ip here") {
if (!empty($referrer)){
$mysqli->query("UPDATE users SET points=points+10, refearn = refearn+10 WHERE username='".$referrer."'") or die(mysqli_error($mysqli));
}
$mysqli->query("UPDATE users SET points=points+".$earnings.", completed = completed+1 WHERE username='".$subid."'") or die(mysqli_error($mysqli));
}
