mysql_query 会话期间未更新数据库

Question

我目前使用会话登录，我希望用户能够更新他们的信息。但是在提交时没有任何反应。该会话有效，因为当我检查 iduser 电子邮件和密码时回显。我想我可能写错了查询或者我使用的会话不正确。有人可以解释为什么数据库中没有更新吗？

    <?php
session_start();
include "connect.php";
include "header.php";
$iduser=$_SESSION['logged_in']['iduser'];
$sql = mysql_query("SELECT * FROM `profile` WHERE `iduser` = '$iduser' ");      
while($row = mysql_fetch_array($sql)){
    $iduser = $row['iduser'];
    $password = $row['password'];   
    $email = $row['email'];                     
    $fnlname = $row['fnlname'];     
    $username = $row['username'];
    $joineddate = $row['joineddate'];                       
    $gender = $row['gender'];   
    $age = $row['age'];
    $location = $row['location'];
    $website = $row['website'];                         
}                       
echo "$iduser $password $email";

Answer 1

您的查询应该是这样的

UPDATE profile SET fnlname='$fnlname', joineddate='$joineddate', gender='$gender', age='$age' ,location='$location', website='$website' WHERE iduser='$iduser'

你错过了逗号 如果$iduser 是一个字符串你必须用单引号封装

mysql_query 会话期间未更新数据库

mysql_query not updating database during session
