Question

我有一个页面，我需要从会话中获取变量以使用变量执行sql查询。

（请原谅我使用mysql而不是mysqli，我将继续工作改变它）

我试过这个$_SESSION["user_name"] = $cnid;它不起作用。

所以我尝试将变量$cnid和$cnin添加到登录页面的网址中，并将其中任何一个添加到用户信息中心页面上，但它们似乎不会出现在url因此用户仪表板页面$_GET没有。如果我做错了什么，请有人告诉我！

以下是登录会话：

<?php
session_start();
include("server-side/ufunctions.php");
if(count($_POST)>0) {
$sqlses="SELECT * FROM consignments WHERE cn='" . mysql_real_escape_string($_POST['user_name']) . "'";
$resultses= mysql_query($sqlses);
$rwses= mysql_fetch_array($resultses);
$cnid = $rwses[1];    
$cnin = $rwses[0];    
$cnn = mysql_real_escape_string($_POST['user_name']);

    if( $cnn == $cnid ) {
        $_SESSION["user_id"] = 1001;
        $_SESSION["user_name"] = $cnid;
        $_SESSION['loggedin_time'] = time();  
    } else {
        //Login Error Msg
       $msge = "<i class=\"fa fa-exclamation-circle\"></i> Consignment Does Not Exist!";
       header("Location:?msge=$msge");
    }
}

if(isset($_SESSION["user_id"])) {
    if(!isLoginSessionExpired()) {
        //Login Success Msg
       $msg = "<i class=\"fa fa-check\"></i> Welcome $cnid! "; //This where i included the cnid variable to echo as a message for test to know if the link is getting the variables, yet no show!
       header("location:$url/server-side/consignment_detail?cnin=$cnin&msg=$msg"); //So included the cnin as a variable into the url still it didnt show!
    } else {
       header("Location:logout_user.php?session_expired=1");
    }
}

if(isset($_GET["session_expired"])) {
        //Login Error Msg
       $msge = "<i class=\"fa fa-exclamation-circle\"></i> You've Been Checked Out. Please Check Back In!";
       header("Location:?msge=$msge");
}
?>

以下是用户信息中心：

<?php 
session_start();
include '_inc/dbconn.php'; 
$sql="SELECT * FROM admin WHERE id='1'";
$result= mysql_query($sql);
$rws= mysql_fetch_array($result);
$url= $rws[7];

include("ufunctions.php");
if(isset($_SESSION["user_id"])) {
    if(isLoginSessionExpired()) {
        header("Location:logout_user?session_expired=1");
    }
}
?>

在“用户信息中心”页面中，不要先将会话值分配给变量，而只是直接使用它。

$_SESSION["user_name"] = $cnid;
$sql1="SELECT * FROM consignments WHERE id='$cnid'";

将其更改为：

$sql1="SELECT * FROM consignments WHERE id='". $_SESSION["user_name"]."'";

我希望现在这可以解决你的问题！：）
