【问题描述】：
我就是无法在 php 中设置会话，也找不到原因。
希望你能给我一个线索，我可能做错了什么！
index.php
<?php
// Inialize session
session_start();
include_once("commons/config.php");
$authenticated = checkLoggedIn("yes", FALSE);
//flushMemberSession();
var_dump($authenticated);
echo "<pre>";
var_dump($_SESSION);
echo "</pre>";
?>
... followed by html and some php ifs
jquery ajax 调用返回 TRUE 或 FALSE，应该从 checkPass() 内部 actions.php
$('#login').click(function(){
var data = $('#login-form').serialize();
$.post('commons/actions.php', data, function(result){
if(result == true){
console.log(result);
//location.reload();
}else{
console.log('not authenthicated');
}
},'json');
return false;
});
actions.php
session_start();
if (!$_SERVER['SERVER_ADDR'] == $_SERVER['REMOTE_ADDR']){
header('HTTP/1.0 400 Unauthorized', true, 400);
exit;
} else {
include('config.php');
$user = mysql_real_escape_string(stripslashes($_POST['username']));
$pass = mysql_real_escape_string(stripslashes($_POST['password']));
$response = checkPass($user, $pass); // false or
$debug = array('user'=>$user, 'pass'=>$pass, 'response'=>$response);
print_r(json_encode($response));
}
功能：
function checkLoggedIn($status, $redirect=TRUE){
switch($status){
case "yes":
if(!isset($_SESSION["loggedIn"])){
if($redirect) {
header("Location: login.php");
exit;
} else {
$authenticated = false;
return $authenticated;
}
} else {
checkLoggedIn("no");
}
break;
case "no":
if(isset($_SESSION["loggedIn"]) && $_SESSION["loggedIn"] === true ){
//header("Location: members.php");
$authenticated = true;
return $authenticated;
}
break;
}
return true;
}
function checkPass($username, $password) {
$query="SELECT username, password FROM users WHERE username='$username' and password='$password'";
$result=mysql_query($query, $link) or die("checkPass fatal error: ".mysql_error());
// Check exactly one row is found:
if(mysql_num_rows($result)==1) {
cleanMemberSession($username);
return true;
/*$row=mysql_fetch_array($result);
return $row;*/
}
//Bad username:
return false;
}
function cleanMemberSession($username) {
session_regenerate_id();
$_SESSION["username"]=$username;
$_SESSION["loggedIn"]=true;
session_write_close();
}

更新2
顺便说一句，var_dump($_SESSION); 的回复是array(0) { }
更新3
我刚刚在index.php中session_start();之后添加了$_SESSION['test'] = 'alex';，并且会话变量已经设置......所以它必须是设置变量的函数......或者谁知道还有什么
【问题讨论】：
-
您忘记描述您的预期和得到的结果（错误消息、错误结果等）
-
我希望它设置 SESSION 变量，但什么也没有
-
请发布 ajax
POST标头和数据以及 ajax 响应。 -
@Quassnoi，我刚刚用标题更新了我的问题，它接缝没问题，不是吗？
-
顺便说一句，ajax 响应标头是在我使用正确的凭据单击登录之后
