Php 正在从文件路径中删除图像

我有一个仪表板，用户可以登录并上传自己的个人资料图片，保存到个人资料中。这会将图像移动到正确的文件夹，并将其正确插入数据库

直到最近，当我注意到图像消失时，它一直工作正常。在inspect控制台中，我注意到图像上出现了

404notfound

错误，因此我检查了文件路径内部，图像不再在那里（因此是404）。用户根本没有删除图像的脚本，只能上传

profile.php:

<p><b>Profile Picture: </b>
<?php 
    $picture = $row['imagePath'];
    if (empty($picture)){
        echo "<img src='profiles/no-image.png' width='100' height='100' >";
    } else {
        echo "<img src='profiles/".$row['imagePath']."' width='100' height='100' >";    
    };
?>
<form action="scripts/edit-picture.php" method="POST" enctype="multipart/form-data">
    <input type="file" name="image"/>
    <input type="submit" name="edit-picture" value="Upload"/>
</p>
</form>

profiles
    image1.jpg
    image2.jpg
profile.php
scripts
    edit-image.php

是否有人在通过

move\u uploaded\u file

将图像移动到文件夹中后，遇到图像实际上从文件夹中消失的情况，如有任何帮助或指导，将不胜感激。

解决图像上传的条件，不要覆盖现有图像文件：

<?php
require 'db.php';
session_start();
$uploadDir = '../profiles/';

// if edit-picture has been clicked on, run this if statement
if (isset($_POST[ 'edit-picture' ])) {


    $studentID = $_SESSION[ 'studentID' ];

    // Creating 4 different variables using the $_FILES global variable to get data about the image that
    // you can view data about a file by doing: print_r($image);
    $fileName = $_FILES[ 'image' ][ 'name' ];
    $tmpName = $_FILES[ 'image' ][ 'tmp_name' ];
    $fileSize = $_FILES[ 'image' ][ 'size' ];
    $fileType = $_FILES[ 'image' ][ 'type' ];

    $filePath = $uploadDir . $fileName;
    // The below doesn't work as it assigns different value to folder and in db for image name
    // $filePath = md5($file_name . microtime()) . substr($fileName , -5, 5);

    if (file_exists($filePath)) {
        header("Location: ../profile.php?img=errorFileNameExists");
        exit();

    } // Checking file size - working
    else if ($_FILES[ "image" ][ "size" ] > 5000000) {
        header("Location: ../profile.php?img=errorFileSizeError");
        exit();
    }
    $info = getimagesize($tmpName);
    // empty $info - not known image
    if (empty($info)) {
        header("Location: ../profile.php?img=errorFileTypeError");
        exit();
    } // This is to show any errors that may occur if the connection fails, this helps with error checking.

    $result = move_uploaded_file($tmpName, $filePath);

    if (!$result) {
        header("Location: ../profile.php?img=errorFileRelocate");
        exit;
    }
    else if (mysqli_connect_errno()) {
        printf("Connect failed: %s\n", mysqli_connect_error());
        exit();
    } else {
        $stmt = $conn->prepare("INSERT INTO `profileImage` (`imagePath`, `studentID`)
            VALUES ( ?, ?) ON DUPLICATE KEY UPDATE `imagePath` = VALUES (`imagePath`) ");
        $stmt->bind_param("si", $fileName, $studentID);
        $stmt->execute() or die("Failed to insert image into the database");

        header("Location: ../profile.php?img=successImageUploaded");
        exit();
    }
}
?>

映像不能从文件系统中消失，我怀疑您是否会收到任何关于您的问题的反馈。但是，您是否有其他脚本可以让用户删除其图片？如果是这样的话，可能里面有错误，不应该删除的文件被删除了。这是一个ideaHi@Pierre我知道，我只是很困惑，没有一个脚本让他们删除他们的图像。你确定图像真的被上传和移动了吗？您是否能够重现该问题？@Pierre是的，图像被移动到文件夹路径中，即
$uploadDir='../profiles/'
并在表
profileImage
中显示为新行，如果您确定图像已上载（使用FTP浏览器检查），则问题不在代码中；也许你的主机的服务器出了大问题，不得不将你的文件恢复到以前的日期我确实尝试过，但是当我尝试上传一张不同的照片时，我收到了“FileNameExists”的消息（即使我尝试上传的新图像的文件名不同），可能是
的顺序，如果
位于错误的位置，则不确定。。。。
