Copying files from a shared folder network using PHP - php

I encounter an error when copying files inside a directory from another computer in a shared network using PHP. Basically here is the code i am using, the recursive function created by #authorAidan Lister to copy whole directories. It is working on my local machine if I use a local file directory, but when I change it to a directory from another computer it gives me an error concerning permissions.
I am sure that I took care of the permissions concerning folder access because I have gone as far as to allow "Everyone" to be able to have full access to the folder for testing purposes , but it still doesn't work. I am lost and have exhasuted all options I can think of.
PHP is the name of my local machine.
VMSTBOX is the name of the computer with the files i am trying to access.
Also, when I use " chmod("\\VMSTBOX\Users", 0777); "in my PHP code.It also gives me a "permission denied " error. I think this is related to my issue.
I have posted a chunk of my source code below along with the error message below. Thanks for any help
function xcopy($source, $dest, $permissions = 0777)
{
// Check for symlinks
if (is_link($source)) {
return symlink(readlink($source), $dest);
}
// Simple copy for a file
if (is_file($source)) {
return copy($source, $dest);
}
// Make destination directory
if (!is_dir($dest)) {
mkdir($dest, $permissions);
}
// Loop through the folder
$dir = dir($source);
while (false !== $entry = $dir->read()) {
// Skip pointers
if ($entry == '.' || $entry == '..') {
continue;
}
// Deep copy directories
xcopy("$source/$entry", "$dest/$entry", $permissions);
}
// Clean up
$dir->close();
return true;
$filelocation="\\\VMSTBOX\\Files";
$newfilelocation="\\\\PHP\\VarTemptoCopy";
$status = xcopy($filelocation, $newfilelocation);
CODE ENDS HERE
Here is the error message i keep getting.
"Warning: dir(\VMSTBOX\Files,\VMSTBOX\Files): Access is denied. (code: 5) in C:\xampp\htdocs...."

failed to open stream: Permission denied open server

My aim is to download multiple files into the folder on my localhost. I am uploading them using the HTML form.
Here is the code (really sorry that I can't give a link to the executable version of the code because it relies on too many other files and database if anyone knows the way then please let me know)
foreach ($_FILES as $value) {
$dir = '/';
$filename = $dir.basename($value['name']);
if (move_uploaded_file($value['tmp_name'],$filename)) {
echo "File was uploaded";
echo '<br>';
}
else {
echo "Upload failed";
echo '<br>';
}
}
So this little piece of code give me an error:
And here are the lines of code:
The problem is that the adress is correct, I tried enterring it into my file directory and it worked fine, I have seen some adviced on other people's related questions that // or \ should be used instead, but my version works just fine! Also I have checked what's inside the $_FILES and here it is if that's required for someone trying to help:
Thank you very much if anyone could help!!
You are trying to move the file to an invalid (or non-existent) path.
For the test you will write
$dir = 'c:/existing_dir/';
$filename = $dir.basename($value['name']);
If you want to move the file to a folder that is relative to the running file try
$dir = '../../directory/';// '../' -> one directory back
$filename = $dir.basename($value['name']);
By starting your file path with $dir = '/'; you are saying store the file on the root folder, I assume of C:
Apache if correctly configures should not allow you access to C:\
So either do
$dir = '../';
$filename = $dir.basename($value['name']);
to make it a relative path or leave the $dir = '/'; out completely

PHP is_dir defective

Strange behaviour, exentially:
(the name of the folder depends on the date - the purpose is a hit counter of the website, broken down by day)
if (!is_dir($folder)) { // first access in the day
mkdir($folder);
}
Well: on the server in internet all works well.
But when i try in local, with the server simulator of Easy PHP, happens that:
(a) The first time, no problem. The folder doesn't exists and it is created.
(b) subsequently, for example to a page refresh, the program flow again goes in the IF (!!!) generating the error (at line of mkdir) of kind: "Warning: mkdir(): No such file or directory in [...]".
All parent part of the directory $folder exists.
Thanks
.
Try using a recursive directory creation function:
function mkdir_r($dirName, $rights = 0777)
{
$dirs = explode(DIRECTORY_SEPARATOR , $dirName);
$dir = '';
if (strpos($dirs[count($dirs) - 1], '.')) {
array_pop($dirs);
}
foreach ($dirs as $part) {
$dir .= $part . DIRECTORY_SEPARATOR ;
if (!is_dir($dir) && strlen($dir) > 0) {
mkdir($dir, $rights);
}
}
}
This way all directories up to the directry you wanted to create are created if they don't exist.
mkdir doesn't work recursively unfortunately.
If anyone faces the issue; Use the native clearstatcache() function after you delete the file.
I'm quoting the interesting part of the original documentation
You should also note that PHP doesn't cache information about non-existent files. So, if you call file_exists() on a file that doesn't exist, it will return false until you create the file. If you create the file, it will return true even if you then delete the file. However unlink() clears the cache automatically.
For further information here is the documentation page: https://www.php.net/manual/en/function.clearstatcache.php

Copying folder to other folder with PHP

I'm trying to move folder to other folder, with all it's files. Both folders are in root directory. Tried a lot of ways, and always get no result.
Here is my latest atempt:
$source = "template/"
$dest = "projects/"
function copyr($source, $dest){
if (is_link($source)) {
return symlink(readlink($source), $dest);
}
if (is_file($source)) {
return copy($source, $dest);
}
if (!is_dir($dest)) {
mkdir($dest);
}
$dir = dir($source);
while (false !== $entry = $dir->read()) {
// Skip pointers
if ($entry == '.' || $entry == '..') {
continue;
}
copyr("$source/$entry", "$dest/$entry");
}
$dir->close();
return true;
}
Need professional glance to tell me, where I'm getting it wrong?
EDIT:
Sorry for wrong tags.
Problem is - nothing is happening. Nothing is being copied. No error messages. Simply nothing happens.
File structure:
I suggest to try and do the following
How do you run the scrips? Do you open page in browser or run script in command line? If you open page in browser this might be an issue with permissions, paths (relative and not absolute) and errors not shown but logged.
Use absolute folder paths instead of relative paths. For example /var/www/project/template.
Apply realpath() function to all paths and check (output) the result. If path is wrong (folder does not exist, separators are wrong etc) you will get empty result from the function.
Make sure to use DIRECTORY_SEPARATOR instead of / if you run your script on Windows. I can not check if / works on Windows now but potentially this might be an issue. For example
copyr($source.DIRECTORY_SEPARATOR.$entry", $dest.DIRECTORY_SEPARATOR.$entry);
Check warnings and errors. If you do not have permission you should get warning like this
PHP Warning: mkdir(): Permission denied
You may need to enable warnings and errors if they are disabled. Try for example to make an obvious mistake with name and check if you get any error message.
Try to use tested solution from one of the answers. For example xcopy function.
Try to add debug messages or run your script in debugger step by step. Check what is happening, what is executed etc. You can add debug output near any operator like (just an idea):
echo 'Creating directory '.$name.' ... ';
mkdir($name);
echo (is_dir($name) ? 'created' : 'failed').PHP_EOL;

Uploading files in PHP - Unzipping and Moving

I have a very basic, very straightforward function that takes a file (after checking it to make sure its a zip among other things) and uploads it, unpacks it and such:
public function theme(array $file){
global $wp_filesystem;
if(is_dir($wp_filesystem->wp_content_dir() . "/themes/Aisis-Framework/custom/theme/")){
$target_path = $wp_filesystem->wp_content_dir() . "/themes/Aisis-Framework/custom/theme/";
if(move_uploaded_file($file['tmp_name'], $target_path . '/' . $file['name'])) {
$zip = new ZipArchive();
$x = $zip->open($target_path);
if ($x === true) {
$zip->extractTo($target_path); // change this to the correct site path
$zip->close();
//unlink($target_path);
}
$this->success('We have uplaoded your new theme! Activate it bellow!');
} else {
$this->error('Oops!', 'Either your zip is corrupted, could not be unpacked or failed to be uploaded.
Please try again.');
}
}else{
$this->error('Missing Directory', 'The Directory theme under custom in Aisis Theme does not exist.');
}
if(count(self::$_errors) > 0){
update_option('show_errors', 'true');
}
if(count(self::$_messages) > 0){
update_option('show_success', 'true');
}
}
Extremely basic, yes I have used my target path as both the path to upload too and unpack (should I use a different path, by default it seems to use /tmp/tmp_name)
Note: $file is the array of $_FILES['some_file'];
My question is I get:
Warning: move_uploaded_file(/var/www/wordpress/wp-content//themes/Aisis-Framework/custom/theme//newtheme.zip): failed to open stream: Permission denied in /var/www/wordpress/wp-content/themes/Aisis-Framework/CoreTheme/FileHandling/Upload/Upload.php on line 82
Warning: move_uploaded_file(): Unable to move '/tmp/phpfwechz' to '/var/www/wordpress/wp-content//themes/Aisis-Framework/custom/theme//newtheme.zip' in /var/www/wordpress/wp-content/themes/Aisis-Framework/CoreTheme/FileHandling/Upload/Upload.php on line 82
Which basically means that "oh the folder your trying to move from is owned by root, no you cannot do that." the folder I am moving too is owned by apache, www-data. - I have full read/write/execute (it's localhost).
So question time:
Should my upload to and move to folder be different?
How, in a live environment, because this is a WordPress theme, will users who have the ability to upload files be able to get around this "you dont have permission"?
You should try to do it the wordpress way. Uploading all user content to wp-content/uploads, and doing it with the native functions.
As you mention, uploading to a custom directory, may be an issue to non tech savvy users. /uploads already have the special permissions.
Check out wp_handle_upload. You just have to limit the mime type of the file.
The path you are trying to upload is some where wrong here
wp-content//themes
try removing one slash

exception in creating directory

Am a beginner in php. My problem is, i use the following code to create a directory and copy some files into it(I used a code get from so itself). The code works fine directory is created and files are copied. But I am getting a warning like this.
function copyr($source, $dest)
{
// Simple copy for a file
if (is_file($source)) {
chmod($dest, 0777);
return copy($source, $dest);
}
// Make destination directory
if (!is_dir($dest)) {
mkdir($dest);
}
chmod($dest, 0777);
// Loop through the folder
$dir = dir($source);
while (false !== $entry = $dir->read()) {
// Skip pointers
if ($entry == '.' || $entry == '..') {
continue;
}
// Deep copy directories
if ($dest !== "$source/$entry") {
copyr("$source/$entry", "$dest/$entry");
}
}
// Clean up
$dir->close();
return true;
}
copyr("agentSourcefolder", "testTemp5");
.
Warning: chmod() [function.chmod]: No such file or directory in /home/websiteName/public_html/php_file_upload2.php on line 9
I have to get the response from server after this, what should i do? I used
header("Location: http://www.websiteName.com/");
But it shows the following error
Warning: Cannot modify header information - headers already sent by (output started at /home/websiteName/public_html/php_file_upload2.php:9) in /home/websiteName/public_html/php_file_upload2.php on line 41
And if the directory is already created this code works fine
This one:
Warning: Cannot modify header information - headers already sent by (output started at /home/websiteName/public_html/php_file_upload2.php:9) in /home/websiteName/public_html/php_file_upload2.php on line 41
is because you are passing the header('location:') call after anything has been written to the screen. All of this processing should be done before anything is written to the page, like echo, breaking out of php, etc. Also make sure there's NO white space before the opening <?php line.
The other error is likely because a file you're trying to chmod doesn't exist or exist yet. Or that you may need to provide an absolute path to mkdir. like $_SERVER['DOCUMENT_ROOT']."/path-to-new-dir/"
