PHP + MySQLi - 尝试使用 enctype="multipart/form-data" 将图像上传到本地主机数据库中的用户行

Question

我正在为登录的用户创建一个用户个人资料更新页面，以编辑他们的姓名、电子邮件和个人资料图片。我已成功更新文本，但无法使图片更新正常工作。没有产生错误，但数据库中的字段从空变为“”（空白）。我已经在下面粘贴了我的更新帐户页面代码，如果您能帮助我找出问题所在，我们将不胜感激！

<?php require 'Assets/Connections/Connections.php'; ?>
<?php session_start(); 
    if(isset($_SESSION["UserID"])){
    }else{
        header('Location: LogIn.php');
        die();
        }
?>
<?php

    $User = $_SESSION["UserID"];

    $result = $con->query("SELECT * FROM user WHERE UserID ='$User'");

    $row = $result->fetch_array(MYSQLI_BOTH);

    $_SESSION["FirstName"] = $row['Fname'];
    $_SESSION["LastName"] = $row['Lname'];
    $_SESSION["Email"] = $row['Email'];
    $_SESSION["PW"] = $row['Password'];
    #$_SESSION["Picture"] = $row['ProfilePicture'];
?>
<?php

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

            $UpdateFName = $_POST['FirstName'];
            $UpdateLName = $_POST['LastName'];
            $UpdateEmail = $_POST['Email'];
            $UpdatePassword = $_POST['Password'];
            $StorePassword = password_hash($UpdatePassword, PASSWORD_BCRYPT, array('cost' => 10));

            move_uploaded_file($_FILES['file']['tmp_name'], 'Assests/Images/'.$_FILES['file']['name']);
                    #move_uploaded_file($_FILES['file']['tmp_name'],"Assets/Images/".$_FILES['file']['name']);


            $sql = $con->query("UPDATE user SET Fname = '{$UpdateFName}', Lname = '{$UpdateLName}', Email = '{$UpdateEmail}', Password = '{$StorePassword}', ProfileImage = '".$_FILES['file']['name']."' WHERE UserID = $User");

            header('Location: Account.php');
            die();
                                }
?>

Answer 1

您的表单元素需要 enctype="multipart/form-data" 才能上传文件

您的表单标签将是

 <form id="form1" name="form1" method="post" enctype="multipart/form-data">

从你的 div

中删除 action="" method="post" enctype="multipart/form-data"

 <div class="FormElement" action="" method="post" enctype="multipart/form-data">
                <input type="file" name="file">
                <br><br>
            </div>

这些是表单元素。你在你的表格中提到这些东西

<div class="FormElement">
                <input type="file" name="file">
                <br><br>
            </div>

阅读form

Answer 2

旅游表格标签有问题，按此更新

<form action="" method="post" enctype="multipart/form-data">
