chmod到777但仍然获得图片上传权限 [英] chmod to 777 but still get permission denied on image upload
问题描述
我一直在使用以下功能（是的，它不够优雅，我说的很多，我说的很久以前就写过了）上传图片。它至少有一年的时间没有问题，而且我不记得最近在任何时候将它更改为b $ b。然而，剧本突然在这个
行上死了：
if（copy（$ uploadedFile，$ pathToImageFolder））{
这是我得到的错误：
警告：无法访问
/home/www/krubner/atp/mcIncludes/mcImages.php在线199
我的第一个想法是检查权限 - 它们被设置为755，但是
来测试它们是否是问题我将它们更改为777.再次尝试
并遇到同样的问题。所以我加入了这行，你会看到下面的
，我试图回应这些值。这就是我得到的：
这里是文件名，这里是文件夹
/ home / krubner / www / atp / mcImages /
没有文件名。我认为这是问题所在，但为什么还有
突然没有文件名？ （我正在运行PHP的4.2.3版本，如果你要求b $ b请求）。
函数uploadImage（）{

图片或文件已上传。如果你想参考它
这是地址：< br>< br>
< a href =''$ imagesFolder''>
$ imagesFolder
< / a>
< BR>< BR>
链接代码这个图像看起来像这样：< br>< br>
& lt; img src =''$ imagesFolder''& gt;
< ; br>< br>
将此代码放在您希望显示此图像的任何页面上：
< br>< br>
< img src =''$ imagesFolder''>
< br>< br>
ALT标签控制鼠标时出现的文字光标在图像上悬停
。如果你输入& lt; img src =''myImage.jpg''
ALT =''在夏洛茨维尔市中心拍摄的照片''& gt;然后单词
''在夏洛茨维尔市中心拍摄的照片'出现了。

另请注意，如果您希望图像浮动在
列的中间，只需将标记& lt; center& gt;在它之前和标签
& lt; / center& gt;在它之后。 （希望所有这些代码编写都将在此软件的未来版本中自动生成;现在，
对不起朋友们，但是你必须亲自编辑这些标签。你想要

I''ve been using the following function (yes, it is inelegant, what can
I say, I wrote it a long time ago) to upload images. Haven''t had a
problem with it for at least a year, and I don''t recall changing it
anytime recently. Nevertheless, the script is suddenly dying on this
line:
if (copy($uploadedFile, $pathToImageFolder)){
This is the error I get:
Warning: Unable to access in
/home/www/krubner/atp/mcIncludes/mcImages.php on line 199
My first thought was to check permissions - they were set to 755, but
to test if they were the problem I changed them to 777. Tried again
and got the same problem. So then I added in the line, you''ll see it
below, where I try to echo out the values. This is what I get:
here''s the file name and here''s the folder
/home/krubner/www/atp/mcImages/
There is no file name. I assume that is the problem, but why is there
suddenly no file name? (I''m running version 4.2.3 of PHP, if you''re
asking).
function uploadImage() {
extract($config = getConfig());
global $forms, $io, $users, $links, $sql, $uploadedFile,
$uploadedFile_size, $uploadedFile_name, $overRide;
$uploadedFile_name = processFileName($uploadedFile_name);
$uploadedFile_name = htmlspecialchars($uploadedFile_name);
if ($uploadedFile_size > 10000000 && $overRide != "true") {
startPage("This image is very large, over 10 megabyte. Are you sure
you want to proceed?");
echo "
<div class=''dvclMcWholeForm''>
<form method=''post'' action=''$self'' enctype=''multipart/form-data''
class=''mcForm''>
Upload this image: <br>
<input type=''file'' name=''uploadedFile''><br><br>
<input type=''hidden'' name=''choiceMade'' value=''uploadImage''>
<input type=''hidden'' name=''overRide'' value=''true''>
<input type=''submit'' value=''Upload File''>
</form>
</div>
";
endPage();
} else {
$pathToImageFolder .= $uploadedFile_name;
$imagesFolder .= $uploadedFile_name;
echo "<br><br><br><br> here''s the file name $uploadedFile_name and
here''s the folder $pathToImageFolder ";
if (copy($uploadedFile, $pathToImageFolder)) {
startPage();
echo "
<div class=''mcForm''>
The image or file has been uploaded. If you wish to reference it
this is the address:<br><br>
<a href=''$imagesFolder''>
$imagesFolder
</a>
<BR><BR>
The code for a link to this image would look like this:<br><br>
<img src=''$imagesFolder''>
<br><br>
Put this code on any page where you want this image to appear:
<br><br>
<img src=''$imagesFolder''>
<br><br>
The ALT tag controls what text appears when the mouse cursor hovers
over an image. If you type <img src=''myImage.jpg''
ALT=''Photo taken in downtown Charlottesville''> then the words
''Photo taken in downtown Charlottesville'' are what appear.
<a href=''http://www.htmlhelp.com/reference/wilbur/syntax.html''>You
can read more about IMG tag syntax on htmlHelp.com</a>
<br><br>
Also note that if you want an image to float in the middle of a
column, just put the tag <center> before it and the tag
</center> after it. (Hopefully all this code writing will be
automated in future versions of this software; for now,
sorry folks, but you''ve got to hand edit these tags if you want
them any different than how they are listed below.)

For some reason the upload failed. This problem might be temporary
or permanent. Try again.

endPage();

function printFormForImageUpload() {
extract($config = getConfig());
// We need to print the form
startPage("Note: certain image types don''t work on the web. Upload
images that have ''jpe'' or ''jpg'' or ''jpeg'' or ''gif'' or ''png'' as their
endings.");
echo "
