【问题描述】:
尝试在我的服务器上进行文件上传。
文件上传不断失败。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 Web 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)。
提交表单后,我在 $_FILES 中看到了该文件,但该文件没有进入 /uploads 文件夹。
以下是文件夹的权限:
drwxr-xr-x 2 www-data forexamplejohn 4096 Dec 16 10:52 aptemp
这里是上传脚本:
<?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);
?>
这里是表格:
<!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
【问题讨论】:
-
stackoverflow.com/a/13841017/1415724 "临时文件;成功上传后PHP会自行清理"。如果临时文件不断堆积,则意味着上传失败。
-
好的,但是我应该在提交表单之前看不到临时文件吗?
-
这将很难跟踪。
-
我只是浏览到该文件夹并偷看不?
-
如果它是一个大文件并且你有时间在这段时间内偷看它,当然......我会说它可能是可见的。
