您好我有一个奇怪的范围问题
require 'connect.php';
$name = $_GET['R'];
echo $name;
if(isset($_POST['prev_password']) && isset($_POST['new_password']) && isset($_POST['rep_password'])) {
echo $name;
if(!empty($_POST['prev_password']) && !empty($_POST['new_password']) && !empty($_POST['rep_password'])) {
$user_password = $_POST['prev_password'];
$user_new_password = $_POST['new_password'];
$user_rep_password = $_POST['rep_password'];
if($user_new_password == $user_rep_password) {
$mysql_query = sprintf("SELECT username, password FROM users WHERE username='$name'", $name);
$query_run = mysql_query($mysql_query, $mysql_link) or die('COULD NOT PERFORM QUERY');
while($row = mysql_fetch_array($query_run)) {
$qUser_name = $row['username'];
$qUser_pass = $row['password'];
}
if($qUser_name == $name) {
echo 'Match';
if($qUser_pass == $user_password) {
$mysql_query = sprintf("UPDATE users SET password='$user_new_password' WHERE username='$name'", $name);
$query_run = mysql_query($mysql_query, $mysql_link) or die('COULD NOT PERFORM QUERY');
echo header('Location: main.php?C=1');
}else {
header('Location: main.php?C=4');
}
}
}else {
header('Location: main.php?C=3');
}
}else {
header('Location: main.php?C=2');
}
}
无论如何,问题在于第一个变量$ name,当我'echo'$ name ok,正确显示内容,但在(如果是sss)ITS EMPTY内,idk为什么,我尝试过使用global, GLOBALS数组,它仍然是空的......所以...查询用空参数执行。
请帮助,如果有人能看到可能出现的错误。
PD:这是一个Changepassword.php $ _GET ['R']来自用户Main.php网站,我知道,我不是哈希密码,这不是真正的问题
