Question

我有一个session.php和一个welcome.php页面。我有我的userprofile。

我正在尝试更新电子邮件字段。

当我更改我的电子邮件地址并按下更新按钮时，我得到echo Update Successful，但它没有更新。我认为它仍然具有会话的旧价值，我需要清除它。

session.php文件：

<?php
include('connection.php');
session_start();

$user_check = $_SESSION['login_user'];


$ses_sql = mysqli_query($db,"select * from clients where email = '$user_check'");

$row = mysqli_fetch_array($ses_sql,MYSQLI_ASSOC);

$_SESSION['email']= $row['email'];
$_SESSION['username']= $row['username'];
$_SESSION['firstname']= $row['firstname'];
$_SESSION['lastname']= $row['lastname'];
$_SESSION['birthdate']= $row['birthdate'];
$_SESSION['street']= $row['street'];
$_SESSION['streetnr']= $row['streetnr'];
$_SESSION['city']= $row['city'];
$_SESSION['plzz']= $row['plzz'];
if(!isset($_SESSION['login_user'])){
  header("

location:http://localhost:81/Left_over_youth_website/pages/login.php");
    }
?>

的welcome.php：

    <?php
     include("../php/session.php");
    ?>

                    <div class="col-md-9">

Answer 1

在更新查询中回显'更新成功'。请尝试以下方法。

在welcome.php中：

<?php     
    if(isset($_POST['btupdate'])){ 
        $email = $_REQUEST['email'];             
        $sql = "UPDATE clients SET emaill = '$email' WHERE email = '$email_session'";

        $update = mysqli_query($db, $sql);
if($update)
{
     echo("update successful");
}

?>

Answer 2

您对此代码有致命错误：

<?php                                 
$email = "SELECT * From Clients";
$sql = "UPDATE clients". "SET emaill = $email". "WHERE email = $email_session";
if(isset($_POST['btupdate'])){
    $update = mysqli_query($db, $sql);
    echo("update sucessful");
}
?>

此部分（“UPDATE clients”。“SET emaill = $ email”。“WHERE email = $ email_session”）返回此字符串“UPDATE clientsSET emaill = example@example.comWHERE email = example2@example.com

试试这个：

$sql="UPDATE clients SET emaill = $email WHERE email = $email_session"

使用concatin时要小心，不会为你增加任何空间。

更改后，您不会更改$ _SESSION [“email”]。你必须添加$ _SESSION [“email”] = $ email;

 <?php                                 
$email = "SELECT * From Clients";
$sql = "UPDATE clients SET emaill = $email WHERE email = $email_session";
$update = mysqli_query($db, $sql);
if($update){
    echo("update sucessful");
}
?>
