上传未到达目标文件夹

Question

正在尝试让文件上传在我的服务器上运行。文件上传一直失败。到目前为止我做了什么：
我指定了临时目录 (/var/tmp/aptemp.) 我将所有权分配给 www-data 以便网络服务器可以写入它。我还在 php.ini 中设置了它并在 phpinfo() 中检查了它。到目前为止一切顺利（我认为）。

我在提交表单后在 $_FILES 中看到了文件，但文件没有进入 /uploads 文件夹。

文件夹的权限如下：

drwxr-xr-x  2 www-data       forexamplejohn 4096 Dec 16 10:52 aptemp

这是上传脚本：

    <?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo " Sorry, there was an error uploading your file.";
    }
}
var_dump($_FILES); 
?>

这是表格：

    <!DOCTYPE html>
<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload Image" name="submit">
</form>

</body>
</html>

这是尝试失败后的输出：

    File is an image - image/png. Sorry, there was an error uploading your file.
array (size=1)
  'fileToUpload' => 
    array (size=5)
      'name' => string '1ERJFa2kBsjhxssQb6gdhu9AtwYQwA7Xhd.png' (length=38)
      'type' => string 'image/png' (length=9)
      'tmp_name' => string '/var/tmp/aptemp/phpf2NewO' (length=25)
      'error' => int 0
      'size' => int 11063

Answer 1

move_uploaded_file() 将 return false 当：

a) 文件名尚未通过 POST

上传

b) 无法将文件复制到目标目录

看起来 b 最有可能是这里的罪魁祸首。在那种情况下，还应该有一个警告 in your server logs 来解释问题。检查目标目录的权限，并确认您已配置 SELinux/AppArmor 以允许 Web 服务器写入目录。
