當用戶登錄時,我將用戶標識存儲到會話中,然後我想將該用戶標識傳遞給ajax以從數據庫中檢索其他信息。存儲在會話 用戶ID沒有被傳遞到allResult.php 我的登錄頁面的代碼段,其中i發出會話:如何使用存儲在會話中的用戶標識與ajax
$msg = '';
if (isset($_POST['login']) && !empty($_POST['username'])
&& !empty($_POST['password']))
{
$username1 = $_POST['username'];
$password1 = $_POST['password'];
$password2 = md5($password1);
$sql= "SELECT * FROM users WHERE userName='$username1' AND password='$password2'";
if($query_run = mysqli_query($conn, $sql))
{
$query_num_rows = mysqli_num_rows($query_run);
$stmt =mysqli_prepare($conn, $sql);
mysqli_stmt_execute($stmt);
mysqli_stmt_store_result($stmt);
if($query_num_rows==1)
{
$row = mysqli_fetch_assoc($query_run);
$user_id = $row['id'];
$name=$row['Name'];
//creating session
$_SESSION['loggedin_time'] = time();
$_SESSION['userid'] = $user_id;
$_SESSION['name'] = $name;
}
}
else {
$msg = '*Wrong username or password';
}
}
現在登錄後,用戶會被帶到儀表板:
<?php
session_start();
include("functions.php");
if(isset($_SESSION["userid"])) {
if(isLoginSessionExpired()) {
header("Location:loginPage.php");
}
}
if($_SESSION['userid']=="" && $_SESSION['name']==""){
header("location: loginPage.php");
}
require 'dbconnect.php';
$userId = $_SESSION['userid'];
echo "$userId";
?>
在儀表板我試圖訪問用戶的其他數據與AJAX
<script id="source" language="javascript" type="text/javascript">
$(function() {
$("#tabs").tabs({active:0});
$.ajax({
url: 'allResult.php',
method:"POST",
data: ({uid:'$userId'}),
dataType: 'json',
success: function(data)
{
var date= data[0]['date'];
var time= data[0]['time'];
var ip= data[0]['ip'];
var lux= data[0]['lux'];
var press= data[0]['press'];
var acc_x= data[0]['acc_x'];
var acc_y= data[0]['acc_y'];
var acc_z= data[0]['acc_z'];
$("#tabs-1").html("<b>date: </b>"+date+"<b> time: </b>"+time+"<b> ip: </b>"+ip+"<b> lux: </b>"+lux+"<b> press: </b>"+press+"<b> acc_x: </b>"+acc_x+"<b> acc_y: </b>"+acc_y+"<b> acc_z: </b>"+acc_z);
} ,
error : function(request,error)
{
alert (error);
alert("Request: "+JSON.stringify(request));
}
});
});
我需要獲得用戶ID爲了運行allResul t.php allResult.php
<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
require 'dbconnect.php';
$user_id = $_POST["uid"]
$sql_query = "SELECT * FROM data where id like '$user_id';";
$result = mysqli_query($conn,$sql_query);
if(mysqli_num_rows($result) >0)
{
$row = mysqli_fetch_assoc($result);
$output [] = $row ;
echo json_encode($output);
}
else
{
echo "Error finding data..";
}
?>
所以最新的問題? – 2016-04-03 19:57:50
不想讀取所有的代碼,但我認爲這可能有助於'<?php echo session_id();?>' –
