PHP 上传权限被拒绝

Question

我制作了一个上传 PHP 脚本，该脚本运行了 5-6 次...现在，当我将它移动到另一个文件时，它无法运行。我收到这条消息

File is an image - image/png. Warning: move_uploaded_file(Viruss.png): failed to open stream: Permission denied in /var/www/html/WEB Dictionary/profile.php on line 57

Warning: move_uploaded_file(): Unable to move '/tmp/phpySH8hY' to 'Viruss.png' in /var/www/html/WEB Dictionary/profile.php on line 57 Sorry, there was an error uploading your file.

HTML代码：

<form action="profile.php" method="post" enctype="multipart/form-data">
       <input type="file" name="ChangeAvatarInput" id="ChangeAvatarInput"><br/>
       <input type="submit" name="ChangeAvatar" value="{$AvatarUpload}">
</form>

PHP代码：

if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST['ChangeAvatar'])) {
 $target_dir = "uploads/";
 $target_file = $target_dir . basename($_FILES["ChangeAvatarInput"]["name"]);
 $uploadOk = 1;
 $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
 $check = getimagesize($_FILES["ChangeAvatarInput"]["tmp_name"]);
 if($check !== false) {
     echo "File is an image - " . $check["mime"] . ".";
     $uploadOk = 1;
 } else {
     echo "File is not an image.";
     $uploadOk = 0;
 }
 if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
 }
 if ($_FILES["ChangeAvatarInput"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
 }
 if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" && $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
 }
 if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
 } else {
 if (move_uploaded_file($_FILES["ChangeAvatarInput"]["tmp_name"], $Username.".".$imageFileType)) {
    echo "The file ". basename( $_FILES["ChangeAvatarInput"]["name"]). " has been uploaded.";
 } else {
    echo "Sorry, there was an error uploading your file.";
 }
 }
}

"uploads" 目录的权限是读写，我使用的是 W3Schools 的示例。

Answer 1

您需要对要复制到的目录进行 chmod 或 chown。所以 chmod/chown 'upload' 所以你有权写入它

Answer 2

在终端中：

如果您位于 project/upload 目录中。

sudo chmod-R 0755 *

这将递归地设置文件夹和子文件夹中所有文件的权限。

如果您不在您的项目中，则：

sudo chmod -R 0755 path_to_your_project

Answer 3

更改此行

move_uploaded_file($_FILES["ChangeAvatarInput"]["tmp_name"], $Username.".".$imageFileType)

至

move_uploaded_file($_FILES["ChangeAvatarInput"]["tmp_name"], '/'.$target_dir.$Username.".".$imageFileType)
