【问题描述】：

您好，我希望登录后的用户能够更新他们的帐户信息。当我填写 for 并点击提交按钮时，我收到了成功消息，但是当我检查我的数据库时，实际上没有任何更新。

我是从这段代码开始的

<?php
    if(!isset($_SESSION['name'])){
    header("location: signin.php");
}


$name=$_SESSION['name'];
$submitted = '';

$sql = "SELECT `name`, `lastname`, `email`, `phone`, `address`, `apt`, `city`, `state`, `zip` FROM `Users` WHERE name = '$name'";
$result = mysqli_query($con,$sql); 
$row = mysqli_fetch_assoc($result);
$acc_name = $row['name'];
$acc_lastname = $row['lastname'];
$acc_email = $row['email'];
$acc_phone = $row['phone'];
$acc_address = $row['address'];
$acc_apt = $row['apt'];
$acc_city = $row['city'];
$acc_state = $row['state'];
$acc_zip = $row['zip'];

?>

<?php

 //UPDATE FORM
if(isset($_POST['save'])){ 

    $name=$_POST['name'];
    $name = mysqli_real_escape_string($con,$name);
    $lastname=$_POST['lastname'];
    $lastname = mysqli_real_escape_string($con,$lastname);
    $email=$_POST['email'];
    $email = mysqli_real_escape_string($con,$email);
    $phone=$_POST['phone'];
    $phone = mysqli_real_escape_string($con,$phone);
    $address=$_POST['address'];
    $address = mysqli_real_escape_string($con,$address);
    $apt=$_POST['apt'];
    $apt = mysqli_real_escape_string($con,$apt);
    $city=$_POST['city'];
    $city = mysqli_real_escape_string($con,$city);
    $state=$_POST['state'];
    $state = mysqli_real_escape_string($con,$state);
    $zip = $_POST['zip'];
    $zip = mysqli_real_escape_string($con,$zip);
    $password= $_POST['password'];
    $hash = password_hash($password, PASSWORD_BCRYPT);

$updateQuery = "UPDATE Users SET name = '$name', lastname = '$lastname', email = '$email', phone = '$phone', address = '$address', apt = '$apt', city = '$city', state = '$state', zip = '$zip', password = '$hash' WHERE name = '$name'";
$updateResult = mysqli_query($con, $updateQuery);
if(!$updateResult){
die('there was an error running query [' . $con->error . ']');

}else{
$submitted = 'Your account has been updated.';
}
}
?>

              </div>
           </div>
      </div>
    </form>

使用上面的这段代码，我不断收到$submitted = 'Your account has been updated.'

但我的数据库中没有更新，我检查了错误日志，没有错误显示。

然后我尝试分离代码并将php放入edit_acc.php

所以我的表单标签操作将是：action="edit_acc.php

编辑-acc.php：

    <?php
    error_reporting(E_ALL);
    ini_set('display_errors', '1');
    session_start();

    if(isset($_SESSION['name'])){
    $name=$_SESSION['name'];
    $submitted = '';
    }



    if(isset($_POST['save'])){ 

    $name=$_POST['name'];
    $name = mysqli_real_escape_string($con,$name);
    $lastname=$_POST['lastname'];
    $lastname = mysqli_real_escape_string($con,$lastname);
    $email=$_POST['email'];
    $email = mysqli_real_escape_string($con,$email);
    $phone=$_POST['phone'];
    $phone = mysqli_real_escape_string($con,$phone);
    $address=$_POST['address'];
    $address = mysqli_real_escape_string($con,$address);
    $apt=$_POST['apt'];
    $apt = mysqli_real_escape_string($con,$apt);
    $city=$_POST['city'];
    $city = mysqli_real_escape_string($con,$city);
    $state=$_POST['state'];
    $state = mysqli_real_escape_string($con,$state);
    $zip = $_POST['zip'];
    $zip = mysqli_real_escape_string($con,$zip);
    $password= $_POST['password'];
    $hash = password_hash($password, PASSWORD_BCRYPT);

    $updateQuery = "UPDATE Users SET name = '$name', lastname = '$lastname', email = '$email', phone = '$phone', address = '$address', apt = '$apt', city = '$city', state = '$state', zip = '$zip', password = '$hash' WHERE name = '$name'";
    $updateResult = mysqli_query($con, $updateQuery);
    if(!$updateResult){
    die('there was an error running query [' . $con->error . ']');

    }else{
    $submitted = 'Your account has been updated.';
    }
    }
    ?>

当我分离代码时，提交edit_acc.php后会显示一个空白页面。表格仍然没有更新，错误日志中仍然没有任何内容。

谁能帮忙？

编辑

我需要更改我的查询：

$updateQuery = "UPDATE Users SET name = '$name', lastname = '$lastname', email = '$email', phone = '$phone', address = '$address', apt = '$apt', city = '$city', state = '$state', zip = '$zip', password = '$hash' WHERE name = '$name'";

到：

感谢 Asisito 推荐使用 id 而不是 name。

【问题讨论】：

尝试 var_dump 你的 $updateResult 变量
当我在 edit_acc.php 中执行 var_dump($updateResult) 时，整个页面都是白色的并打印了“bool(true)”，但它仍然没有在我的数据库中更新。

标签： php html mysqli

【解决方案1】：

我在你的代码中看不到任何初始化 mysqli 数据库连接的部分，比如

$con = mysqli_connect("my_host","my_user","my_password","my_db");

我建议把这段代码放在edit-acc.php之后

if(isset($_SESSION['name'])){
$name=$_SESSION['name'];
$submitted = '';
}

因为那时你开始使用 $con。

编辑：我认为使用唯一 ID 比使用 $name 更好，因为可以多次使用相同的名称。因此，您可以将用户 ID 存储在 Session 中，并根据数据库的需要在某些点获取您需要的所有数据。

【讨论】：

会话开始后，我确实在两个页面上都有数据库连接。我的问题中没有包含那段代码。我会更新它。尽管即使连接了数据库，它也不起作用。我知道它已提交，但在我的数据库中没有更新。
是的，不久前我意识到使用 id 会更好。一切正常后，我会回去更改它。
@Asisito 感谢您将我的更新查询从 WHERE name = '$name' 更改为 WHERE id='23' 它开始工作。我想使用名称的问题是我也在尝试更新名称。所以我肯定会回去并将 id 存储在我的会话中。
