尝试在我的服务器上运行文件上传。
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,因此Web服务器可以写入它。我也在php.ini中设置它并在phpinfo()中检查它。到目前为止一切都很好(我认为)。
我在表单提交后在$ _FILES中看到该文件,但该文件没有进入/ uploads文件夹。
以下是文件夹的权限:
<?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);
?>
这是上传脚本:
<!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>
这是表格:
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
这是尝试失败后的输出:
{{1}}
答案 0 :(得分:1)
move_uploaded_file()
将返回false:
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是最可能的罪魁祸首。在这种情况下,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,并确认已配置SELinux / AppArmor以允许Web服务器写入目录。
