So here's the story, im not very experienced with php, and recently moved to a new host and my website worked prefectly on the old host but on the new host there are errors with the code.
The error message says :
Warning: copy() [function.copy]: Unable to access http://i.imgur.com/USlH6p2.jpg in (directory)
Heres the code where it says there is an error
function upload_image_remote($image, $name) {
$upload_dir = APP_PATH . '/image.uploads';
//check for directory rights
if(!is_writable($upload_dir)) {
echo do_error(_('Folder image.uploads is not writeable'));
exit;
}
//check if there's a directory for today uploads
$today = date("d-m-Y");
if(!is_dir($upload_dir .'/' . $today)) {
if(!mkdir($upload_dir .'/' . $today, 0777)) {
echo do_error(_(sprintf('Folder <strong>image.uploads/%s</strong> could not be created. Please check permissions to be 0777.', $today)));
exit;
}
}
$upload_path = $upload_dir .'/' . $today;
(--> this is where) return copy($image, $upload_path .'/'. $name);
}
I think it may be a permissions problem since it worked perfectly on (old host) 000webhost, anyone have any ideas on what can be wrong with the code ?
Thanks
My guess would be that the copy function is trying to access the remote file and cannot due to the PHP settings.
I think most hosting companies, for security reasons, will have allow_url_fopen = 0. This means that you will not be able to read from the remote location (http://www.site.com/foo.gif). However, you will be able to read from the local file system.
From the PHP documentation:
This option enables the URL-aware fopen wrappers that enable accessing URL object like files. Default wrappers are provided for the access of remote files using the ftp or http protocol, some extensions like zlib may register additional wrappers.
To check this, view the current PHP settings on the server by creating a file with the following contents in your web root. Your looking for the allow_url_fopen setting.
<?php
echo phpinfo();
?>
Give folder permission 0755 Set correct path of temp folder for file
system.
I'm making a utility that provides a GUI to easy edit certain values in a csv file on a remote server. My boss wants the utility in php running on the private webserver. I'm new to php, but I was able to get the GUI file modifier working locally without issues. The final piece now is rather than the local test file I need to grab a copy of the requested file off of the remote server, edit it, and then replace the old file with the edited one. My issue is uploading and downloading the file.
When I searched for a solution I found the following:
(note in each of these I am just trying to move a test file)
$source = "http://<IP REMOTE SERVER>/index.html";
$dest = $_SERVER['DOCUMENT_ROOT']."index.html";
copy($source, $dest);
This solution ran into a permissions error.
$source ="http://<IP REMOTE SERVER>/index.html";
$destination = $_SERVER['DOCUMENT_ROOT']."newfile.html";
$data = file_get_contents($source);
$handle = fopen($destination, "w");
fwrite($handle, $data);
fclose($handle);
This also had a permissions error
$connection = ssh2_connect('<IP REMOTE SERVER>', 22);
ssh2_auth_password($connection, 'cahenk', '<PASSWORD>');
ssh2_scp_recv($connection, '/tmp/CHenk/CHenk.csv', 'Desktop/CHenk.csv');
This solution has the error Fatal error: Call to undefined function ssh2_connect() which I have learned is because the function is not a part of the default php installation.
In closing, is there any easy way to read/write files to the remote server through php either by changing permissions, having the php extension installed, or a different way entirely that will work. Basically I'm trying to find the solution that requires the least settings changes to the server because I am not the administrator and would have to go through a round about process of getting any changes done. If something does need to be changed instructions on doing so or a link to instructions would be greatly appreciated.
Did you set the enable-url-fopen-wrapper in your php.ini?(only if your php version is older)
Please look # php remote files storing in example 2
I've setup ActivePerl on my Windows machine and can run Perl scripts on WAMP. I am setting up Uber-Uploader and now it just telling me ERROR: Failed to find flength file.
I've set all the paths in uber.ini and in the Perl script. I guess there's something missing out there. :(
The errors you're getting are in the PHP scripts.
The name for the file that's missing is set like this:
$flength_file = $TEMP_DIR . $UPLOAD_ID . '.dir/' . $UPLOAD_ID . '.flength';
Try looking into that and please also edit your tags to include php instad of perl.
I am right at the start of trying to write some PHP code to run on a Linux box on an EC2 server that will read files from my S3 bucket, zip them then write the zip file back to the bucket.
I have instantly run in to problems with even creating a simple zip archive from some images on the local disk of the EC2 instance, I am using a script to test out the idea from the PHP manual online and also have tried out a script from David Walsh - http://davidwalsh.name/create-zip-php which looks like it will be great. Neither result in an actual zip file and both give me different status results -
the first snippet from the php manual (to which i add the variable $thisdir)-
<?php
$zip = new ZipArchive();
$filename = "test112.zip";
$thisdir = "/uploads/";
if ($zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE) {
exit("cannot open <$filename>\n");
}
$zip->addFromString("testfilephp.txt" . time(), "#1 This is a test string added as testfilephp.txt.\n");
$zip->addFromString("testfilephp2.txt" . time(), "#2 This is a test string added as testfilephp2.txt.\n");
$zip->addFile($thisdir . "/too.php","/testfromfile.php");
echo "numfiles: " . $zip->numFiles . "\n";
echo "status:" . $zip->status . "\n";
$zip->close();
?>
output =
numfiles: 2 status:11
I dont see any zip file in my 'uploads' folder
The second bit of code i try ( i wont post the code here) - I pass real files and it returns
The zip archive contains 2 files with a status of 0
What are the status messages. I have checked to see if I have the correct libraries installed by looking at the output of phpinfo(); and under the ZIP heading I see -
Zip enabledExtension Version $Id: php_zip.c,v 1.1.2.43 2008/01/18 00:51:38 pajoye Exp $
Zip version 1.8.11
Libzip version 0.8.0-compatible
I have checked the permissions of the files PHP files with the code I am executing and they are set to 777 as is the folder I am trying to add the ziparchive to. I know that this should not remain at 777.
any ideas why I cannot see a zip file? what do the status values mean? Is there a good tutorial out there for using PHP to zip files on an Amazon S3 bucket? or a good utility to provide this functionality?
cheers
You can find it here:
http://www.php.net/manual/en/zip.constants.php
Error 11 is "Can't open file"
In my case i got error code 11 while opening a zip file for reading. The path and permissions are OK. I just changed the DIRECTORY SEPARATOR from back slash (\) to forward slash (/) and it worked. The strange thing is that forward slash (/) paths are in Linux where as I am working in windows server 2003.
I am writing a simple SFTP client in PHP because we have the need to programatically retrieve files via n remote servers. I am using the PECL SSH2 extension.
I have run up against a road block, though. The documentation on php.net suggests that you can do this:
$stream = fopen("ssh2.sftp://$sftp/path/to/file", 'r');
However, I have an ls method that attempts to something similar
public function ls($dir)
{
$rd = "ssh2.sftp://{$this->sftp}/$dir";
$handle = opendir($rd);
if (!is_resource($handle)) {
throw new SFTPException("Could not open directory.");
}
while (false !== ($file = readdir($handle))) {
if (substr($file, 0, 1) != '.'){
print $file . "\n";
}
}
closedir($handle);
}
I get the following error:
PHP Warning: opendir(): Unable to open ssh2.sftp://Resource id #5/outgoing on remote host
This makes perfect sense because that's what happens when you cast a resource to string. Is the documentation wrong? I tried replacing the resource with host, username, and host and that didn't work either. I know the path is correct because I can run SFTP from the command line and it works fine.
Has anyone else tried to use the SSH2 extenstion with SFTP? Am I missing something obvious here?
UPDATE:
I setup sftp on another machine in-house and it works just fine. So, there must be something about the server I am trying to connect to that isn't working.
When connecting to a SFTP server and you need to connect to the root folder (for instance for reading the content of the folder) you would still get the error when using just "/" as the path.
The solution that I found was to use the path "/./", that's a valid path that references to the root folder. This is useful when the user you are logging with has access only to its own root folder and no full path is available.
So the request to the server when trying to read the contents of the root folder should be something like this:
$rd = "ssh2.sftp://{$this->sftp}/./";
For php versions > 5.6.27 use intval()
$sftpConnection = ssh2_connect($host);
$sftp = ssh2_sftp($sftpConnection);
$fp = fopen("ssh2.sftp://" . intval($sftp) . $remoteFile, "r");
https://bugs.php.net/bug.php?id=73597
I'm having a similar issue. I assume you are doing something similar to this:
$dir = "ssh2.sftp://{$sftp}{$remote_dir}";
$handle = opendir($dir);
When $remote_dir is the full path from root then open_dir works. If $remote_dir is just '/' or '', then I get the 'unable to open' error as you did.
In my case, it seems ssh connects at the root folder instead of the 'home' directory as ftp does. You mentioned that it worked on a different server, so I wonder if it is just a config issue.
the most easiest way to get SFTP working within PHP (even on windows) without installing any extension etc is PHPSECLIB: http://phpseclib.sourceforge.net/ . The SSH stuff is completely implemented in a PHP class.
You use is like this:
<?php
include('Net/SFTP.php');
$sftp = new Net_SFTP('www.domain.tld');
if (!$sftp->login('username', 'password')) {
exit('Login Failed');
}
echo $sftp->pwd();
?>
The documentation on that page contains an error. Take a look at the example here instead: http://php.net/ssh2_sftp - what you actually need to do is to open a special SFTP resource using ssh2_sftp() prior to using it with fopen(). And yes, it looks just like that, e.g. "Resource #24" when converted to string... a bit weird but apparently it works.
Another caveat is that SFTP starts in the root directory rather than the home directory of the remote user, so your remote path in the URI should always be an absolute one.
I just had the same issue, but I could figure out the problem.
On my case, when connecting to the server, I was going to the root of the account, and due to server configs I wasn't able to write there.
I have connected to the account using a fireFTP, and so I could see where the root of the account was...it was the root of the server.
I had to include the whole path until the folder where I am allowed to write, and so I could solve the issue.
So, my advice is to get the path using a graphic interface (I have used fireFTP), and add the whole path to your code.
$pathFromAccountRootFolderToMyDestinationFolder = '/Account/Root/Folder/To/My/Folder';
$stream = fopen("ssh2.sftp://".$sftp."/".$pathFromAccountRootFolderToMyDestinationFolder."/myFile.ext", 'r');
Hope this will help you and other people with the same issue!
Cheers!
I recently tried to get SFTP on PHP working and found that phpseclib was a lot easier to use:
http://phpseclib.sourceforge.net/
If you have the luxury of not being on a shared host and can install whatever extensions you want to maybe the PECL extension would be better but not all of us are so lucky. Plus, phpseclib's API looks a bit more intuitive, being OOP and all.
My issue was, that I was connecting in function and returning string URL with resource inside. Unfortunatelly resource is than created in function context and garbage collector is disconnecting resource on function end. Solution: return resource by reference and unset it manually in more complex context.
Solved my issue by enabling sftp support on the (Powershell) server
This is a bug in the ssh2 package that I found years ago and posted a patch to php.net. It fixes this issue but requires a rebuild of the ssh2 pecl package. You can read more here: https://bugs.php.net/bug.php?id=69981. I included a patch there to the ssh2_fopen_wrappers.c file in the package to fix the issue. Here is a comment I included:
Here is a line of code from ssh2_fopen_wrappers.c that causes this bug: (comment included)
/*
Find resource->path in the path string, then copy the entire string from the original path.
This includes ?query#fragment in the path string
*/
resource->path = estrdup(strstr(path, resource->path));
This line of code -- and therefore this bug -- was introduced as a fix for bug #59794. That line of code is attempting to get a string containing the part, query and fragment from the path variable.
Consider this value for the path variable:
ssh2.sftp://Resource id #5/topdir?a=something#heading1
When resource->path is "/topdir", the result is that "/topdir?a=something#heading1" gets assigned to resource->path just like the comment says.
Now consider the case when resource->path is "/". After the line of code is executed, resource->path becomes "//Resource id#5/topdir#heading1". This is clearly not what you want. Here's a line of code that does:
resource->path = estrdup( strstr( strstr( path, "//" ) + 2, "/" ) );
You may also need to apply the patch for bug # 73597 which removes "Resource id #" from the path string before calling php_url_parse().
