所以我的 php 登录脚本有一个愚蠢的问题。我注意到,当我尝试使用它并登录时,它在 login.php 上设置了会话变量,但是当我尝试移动页面时,它会破坏它。因此,在 login.php 上,我检查用户名和密码是否与数据库行匹配,如果匹配,则设置一个变量,告诉站点用户已登录。然后我检查站点内的变量,如果设置好了,我让他们查看网站的内部,如果没有设置,我会踢他们。
所以这是我的 login.php
<?php
include 'functions/functions.php';
$db = mysqlconnect();?>
<?php
error_reporting(0);
session_start();
?><?php
if (isset($_POST["Submit"])) {
$password = mysql_real_escape_string($_POST['password']);
$password2 = strip_tags($password);
$md5password = md5($password2);
$statement = $db->prepare("SELECT * FROM users WHERE username = ? AND password = ? ");
$statement->execute(array($_POST['username'],$md5password));
$count = $statement->rowCount();
/// If usernam and password match we carry on
if ($count == "1")
{
$username23 = mysql_real_escape_string($_POST['username']);
$thereusername = strip_tags($username23);
$_SESSION['username'] = $thereusername ;
echo "You are now being logged in";
//Test if it is a shared client
if (!empty($_SERVER['HTTP_CLIENT_IP'])){
$ip=$_SERVER['HTTP_CLIENT_IP'];
//Is it a proxy address
}elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){
$ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
}else{
$ip=$_SERVER['REMOTE_ADDR'];
}
$result5534453465 = mysql_query("UPDATE users SET lastip='".$ip."' WHERE username='".$_SESSION['username']."'")
or die(mysql_error());
mysql_query("INSERT INTO user_log (username, ip)
VALUES ('".$_SESSION['username']."', '".$ip."')");
echo '<META HTTP-EQUIV="Refresh" Content="0; URL=home.php">';
exit;
}else{
echo "Password or username is wrong";
}
}
?>
<form name="input" action="" method="post">
<p>Username:</p>
<p>
<input type="text" name="username" id ="username">
</p>
<p>Password: </p>
<p>
<input type="password" name="password" id = "password">
</p>
<p>
<input type="submit" value="Submit" name = "Submit">
</p>
</form>
我已经尝试回显 $_SESSION['username'] 是因为用户被重定向到该站点并且它回显正确,因此它被设置正确....
所以然后在网站的内部我检查它是否正在设置 $_SESSION['username']
ini_set('session.cookie_httponly',true);
session_start();
if(isset($_SESSION['last_ip']) == false){
$_SESSION['last_ip'] = $_SERVER['REMOTE_ADDR'];
}
if ($_SESSION['last_ip'] !== $_SERVER['REMOTE_ADDR']){
session_unset();
session_destroy();
}
if(empty($_SESSION['username'])){
echo '<META HTTP-EQUIV="Refresh" Content="0; URL=login.php">';
exit;
}
出于某种原因,页面说用户名是空的......有趣的是,如果我注销破坏整个会话然后尝试登录它会起作用......
编辑:我刚刚编辑了这段代码
//Test if it is a shared client
if (!empty($_SERVER['HTTP_CLIENT_IP'])){
$ip=$_SERVER['HTTP_CLIENT_IP'];
//Is it a proxy address
}elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){
$ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
}else{
$ip=$_SERVER['REMOTE_ADDR'];
}
至
//Test if it is a shared client
if (!empty($_SERVER['HTTP_CLIENT_IP'])){
$_SESSION['last_ip']=$_SERVER['HTTP_CLIENT_IP'];
//Is it a proxy address
}elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){
$_SESSION['last_ip']=$_SERVER['HTTP_X_FORWARDED_FOR'];
}else{
$_SESSION['last_ip']=$_SERVER['REMOTE_ADDR'];
}
现在一切似乎都奏效了......我猜
if(isset($_SESSION['last_ip']) == false){
$_SESSION['last_ip'] = $_SERVER['REMOTE_ADDR'];
}
if ($_SESSION['last_ip'] !== $_SERVER['REMOTE_ADDR']){
session_unset();
session_destroy();
}
正在杀死会话?
另一个编辑:我刚刚注意到,在我检查了上面的编码之后,登录现在适用于 firefox,但不适用于 chrome,在登录后移动到不同的页面后,会话变量没有在 chrome 中设置。我想可能是主机问题?我正在使用 php 版本 5.2 我已经升级到 5.3 但仍然有问题...
