Question

我有php上传问题，我有以下代码：

define('GW_UPLOADPATH', '/var/www/train/ch5/images/');
$name = $_POST['name'];
$score = $_POST['score'];
$screenshot = $_FILES['screenshot']['name'];

$target = GW_UPLOADPATH.$screenshot;
echo $_FILES['screenshot']['tmp_name'].'<br/>';
move_uploaded_file($_FILES['screenshot']['tmp_name'], $targe)
or die("Upload Error!");

我收到上传错误！上传文件的临时文件是：

的/ tmp / php9Khayp

但在/ tmp我找不到这个文件。我正在研究Ubuntu 10.10。有谁能说我问题出在哪里？

apache error.log：[Wed Aug 10 20:54:17 2011] [error] [client ::1] PHP Warning: move_uploaded_file(/var/www/train/ch5/images/phizsscore.gif): failed to open stream: Permission denied in /var/www/train/ch5/addscore.php on line 22, referer: http://localhost/train/ch5/addscore.php [Wed Aug 10 20:54:17 2011] [error] [client ::1] PHP Warning: move_uploaded_file(): Unable to move '/tmp/phpmkZEr3' to '/var/www/train/ch5/images/phizsscore.gif' in /var/www/train/ch5/addscore.php on line 22, referer: http://localhost/train/ch5/addscore.php [Wed Aug 10 20:54:18 2011] [error] [client ::1] File does not exist: /var/www/favicon.ico

Answer 1

你有一个错字。 $targe应为$target。

move_uploaded_file($_FILES['screenshot']['tmp_name'], $targe)
                ---------------------------------------^^^^^^

否则，您永远无法在/tmp中看到该文件，因为它只会在PHP脚本的生命周期内持续存在。脚本执行完成后，文件将被清除。在脚本终止后，您无法在磁盘上访问它，除非成功调用move_uploaded_file()。

<强>更新

如果$target变量不是问题，请确保Apache Web服务器用户（www-data，httpd，apache是possibilites）具有对目标/var/www/train/ch5/images/的写访问权限：

# assuming the Apache user is apache...
sudo chown root:apache /var/www/train/ch5/images/
sudo chmod g+rwx /var/www/train/ch5/images/

Answer 2

您的代码是否有权将文件写入/ tmp？

apache错误日志会说什么吗？
