我坚持可能是文件权限问题。我已经花了10个小时直接在这上面,我就放弃了,因为我根本不知道如何解决它。我的脚本也适用于localhost。
我在CodeIgniter应用程序的控制器中有以下代码作为文件上传脚本的一部分:
$this->load->library('image_lib');
$config['upload_path'] = '/tmp/';
$this->load->library('upload', $config);
$this->upload->do_upload("selected_file");
// Variables used later when resizing an image
$originalPostImageFileUploadPath = $this->upload->data()['full_path'];
$originalPostImageFileUploadFilePath = $this->upload->data()['file_path'];
$originalPostImageFileRawName = $this->upload->data()['raw_name'];
$originalPostImageFileExt = $this->upload->data()['file_ext'];
$originalPostImageFileUniqId = uniqid();
print_r($this->upload->data());
echo file_get_contents($originalPostImageFileUploadPath);
这是我上传文件时得到的输出:
Array
(
[file_name] => fosters.jpg
[file_type] => image/jpeg
[file_path] => /tmp/
[full_path] => /tmp/fosters.jpg
[raw_name] => fosters
[orig_name] =>
[client_name] => fosters.jpg
[file_ext] => .jpg
[file_size] => 49408
[is_image] => 1
[image_width] =>
[image_height] =>
[image_type] =>
[image_size_str] =>
)
<div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">
<h4>A PHP Error was encountered</h4>
<p>Severity: Warning</p>
<p>Message: file_get_contents(/private/tmp/fosters.jpg): failed to open stream: No such file or directory</p>
<p>Filename: ajax/product.php</p>
<p>Line Number: 45</p>
如您所见,脚本似乎正确上传文件,但file_get_contents()失败,因为它无法找到该文件。
我尝试过的事情:
使用以下代码创建脚本以查看www-data是否具有足够的权限:
echo (is_writable('/tmp/') ? "yes" : "no");
echo (is_readable('/tmp/') ? "yes" : "no");
上述两个输出都返回&#39;是&#39; (真)
更改/ tmp /目录的chmod:
chmod 777 /private/tmp/
(就像这一样糟糕)
将upload_max_filesize
更改为128M
(文件远未达到此大小)
我甚至尝试运行以下命令来查看文件是否上传到/ tmp /目录。它似乎确实如此,但它会立即被删除(在不到0.1秒的时间内)。
watch --interval=0.1 ls
我还能尝试什么? whoami
返回www-data
,我是否正确地说chown wwww-data /tmp/
之类的内容应该解决问题?帮助
答案 0 :(得分:0)
通常通过PHP发送的文件上传发送到临时/文件夹/文件并删除如果你不使用推荐的功能,包括:move_uploaded_file()
例如我的POSTed数组有:
name
size
type
tmp_name
我使用这样的东西:
$fileName=$_FILES["resume"]["name"];
$fileSize=$_FILES["resume"]["size"];
$fileType=$_FILES["resume"]["type"];
$fileTmpName=$_FILES["resume"]["tmp_name"];
$targetFile="/srv/www/uploads/".$fileName; // Where-ever you want your file to be, you can delete manually later on in the script
/* various checking of size and type etc */
if(!is_uploaded_file($fileTmpName)) {
echo "Couldn't upload file";
die(0);
}
if(!move_uploaded_file($fileTmpName,$targetFile)) {
echo "Couldn't move file";
die(0);
}
/* now target file exists and stays put */
