Allow Uploads From Different IP?

Mar 8, 2010

I have two sites with the same content on the same server but under two different IP addresses (which I suspect may be the problem) On user photo uploads, they fail on the new site that's under a different IP though the database and ever ything else is fine. They use the same photos with a symbolic link and the upload path is for the original site. So I suspect that its a php or Unix permissions issue with uploading from a different IP address.


File Uploads Over 40 MB Cause 500 Error - Smaller Uploads Work Just Fine

Jun 8, 2011

I use this PHP upload script that uses Ajax: [URL] Really great script. However, when people upload a file over 40 MB (or maybe after a specific amount of minutes) the upload fails at 100%, when I check the Ajax-response I see a "500 Error". I checked the global error_log and per-site error_log, couldn't find any error there. php.ini max filesize is 300M, post max size is also 300M. php.ini max execution time is 0. All of these values are in the global php.ini.

Uploads Folder Outside Of 'public_html' Enough To Keep Application Secure From Malicious Uploads?

Jun 3, 2010

Although I realise there are different approaches to securing upload process, I'm still confused when it comes to basic principles. I want to allow users to upload any kind of file they want, but keep my app secure. So my question is: Is it sufficient to store the files with their original names in 'uploads' folder outside 'webroot' and fetching them via some download.php script?

If it't not secure enough, please point me in the right direction, or suggest what additional steps I should take to make it safe.

Post - File Uploads Being "hijacked" By Partial Uploads?

Mar 4, 2009

I have a site that is receiving 30-40k photo uploads a day and I've been seeing an issue pop up with more frequency now. This issue is this:

Our upload script receives (via $_FILES['name']['tmp_name']) a file (photo) that was NOT uploaded by the user & the majority of the time the file received is a "partial" upload.

Of course at first I thought it was my PHP code making a simple mistake and I've spent days looking over it to make sure, but after placing checks in the code I've found that the file received via a HTTP POST upload to PHP is actually the wrong file. So the issue is happening before it reaches my code. The tmp file (phpxxxx) received by the script is sometimes incorrect, as if it was somehow being overwritten by another process and its usually overwritten by a file that was partially uploaded.

Has anyone every seen an issue like this? Any help is greatly appreciated. I'm turning to this as a last resort after days of searching/asking other PHP devs

So to recap:

User uploads a photo PHP script receives a file that was not uploaded by the user (pre code, via $_FILES in /var/tmp) Usually the incorrect file received is a partial upload or a broken upload It seems to happen randomly and not all the time

FTP Uploads

Dec 16, 2004

I have written an ftp script. When I execute it, the file is recognized by the script, the remote server is connected, and the ftp user is able to log in. However, I have only been able to upload one particular file and no others. I know this is weird, but the only file that it will accept is the source code of the script itself. It transfers this file with no problems.

This is a weird problem. At the risk of spamming my code and iritating people, in order to save time, I will go ahead an post the code for this script.

<input type=file name=target_file>
<input type=submit name=submit_file>


$filename = $_FILES['UPLOADED_FILE']['name'];
$filesize = $_FILES['UPLOADED_FILE']['size'];

$ftp_server = "server";
$ftp_login = "user";
$ftp_pass = "pass";
$remote_path = "remote_path/ftp_uploads";

echo "<font color="#D20000">ERROR:</font> Please select a valid file to upload.<br>";
{ $ftp_connection_handle = ftp_connect($ftp_server, 21);

echo "<font color="#D20000">ERROR:</font> Could not establish an ftp connection.<br>";
$ftp_login_handle = ftp_login($ftp_connection_handle, $ftp_login, $ftp_pass);

echo "<font color="#D20000">ERROR:</font> Could not successfully login to ftp server.<br>";

ftp_pasv($ftp_connection_handle, true);

if(ftp_put($ftp_connection_handle, $remote_path.$filename, $filename, FTP_BINARY))
echo "File <b>$filename</b> uploaded successfully in BINARY format.<br>";
else if(ftp_put($ftp_connection_handle, $remote_path.$filename, $filename, FTP_ASCII))
echo "File <b>$filename</b> uploaded successfully in ASCII format.<br>";
echo "<font color="#D20000">ERROR:</font> File <b>$filename</b> was not uploaded.<br>";

$server_OS = ftp_systype($ftp_connection_handle);

echo "<br><br><u>File info</u><br>File: $filename<br>Size: $filesize";
echo "<br><br><u>Server info</u><br>Server OS: $server_OS";

Max Uploads

Mar 22, 2006

I know this question has probably been asked before but i cant find any definitive answers anywhere.. Performance wise what is the maximum file size that can be uploaded by php? I know that you set it in php.ini file and i have full control of the server so i can change these settings when needed.

The program i am going to make is like a drop box for files between 50mb and 200mb, would this be a problem doing it with PHP upload? would any other applications be put at risk of shutting down if the user is uploading files? are there any modules / applets that would help the running of the upload system (animation to show how much has been uploaded?). Plus any other problems that i may come accross.

File Uploads With PHP

Jul 17, 2005

I'm writing an uploading page for a website I'm working on. This
website will hopefully allow users to upload files of up to 100MB in
size. The web administrator has increased all the limiting variablies
in php.ini such as:

post_max_size = 150M
upload_max_filesize = 150M
max_execution_time = 600

MAX_FILE_SIZE within the uploading form is also set to 150MB.

However if I try to upload a file greater then 20MB from a PC within
my companys office i get an error message saying that the request is
too large for our web cache. I'm also told that if other users have a
web cache between them and their internet connection they could
experience the same problem.

Does anyone know a way round this problem? Is it possible to bypass
the web cache somehow so that this dosent happen?

Image Uploads

Jan 4, 2006

I am building a community website. It will have a Content Management System that I am building myself. I will be building an Admin Control Panel dat will allow admin to "approve" members so that certain ones can become authors and submit articles through the CMS. Now here is my dilema. Once they are approved, I want a directory to be created (which will reflect the users screenname) so that all the images that they load related to their articles can be loaded there.

1. What is the best way to create these directories? (FTP or MKDIR)
2. What is the best way to upload the files? (securely)
3. Any suggestions or pointers on how to allow users to include these images in their articles?

PHP And File Uploads

Jul 17, 2005

Here's one thing that I don't know much about - file uploading. As part of my project, I will have to build a file manager of sorts - perhaps a document manager. Anyhow, this involves allowing my user to upload files to a location. I know PHP can do it - I know this because it sure does everything else. but I don't know this from any authoritative source. can you tell me if PHP can handle files uploads, and if so, what are the drawbacks that you might have learned of in your experience? For instance, in the ASP world, using a COM object for the upload works, but apparently has significant impact on performance.

NON-image Uploads

Nov 3, 2005

I know that you can get the actual mime type of a valid image file in the getImageSize() array's 3rd element since the mime type header in the $_FILES array can be spoofed, but what if I want to handle uploading of mp3 files (or anything else, for that matter)? Is there a way to arbitrarily get the mime type of an uploaded file? I know that I could probably find documentation for the structure of each file type that I want to handle and then parse the binary data to grab the file type, but I'm not experienced in that type of programming, and I'd like to find a more elegant solution.

Splitting Uploads Up

Sep 24, 2005

I am currently trying to write a simple PHP script that will split an uploading file up into 500kb "chunks", then read and concatenate them back together when accessed for download. I can't seem to be able to find a way to split the file purely in PHP while it is in the middle of uploading using the move_uploaded_file function. I am trying to get it to store the file like so:

MySong.mp3 3mb
gets uploaded to my server in this format:

/uploads/MySong/1 500kb
/uploads/MySong/2 500kb
/uploads/MySong/3 500kb
/uploads/MySong/4 500kb
/uploads/MySong/5 500kb
/uploads/MySong/6 500kb.

How To Do Secure File Uploads?

Oct 15, 2007

How to do secure file uploads with php? Or, more correctly, how to upload to a secured dir? Many apps and posts I have seen on the web advise that the target dir must be writable. Now, this is ok if I am the owner of the dir, but what about if I want my users to be able to e.g. upload an image? Unless I authenticate them as an ftp user on the system, with access to the folder, the folder must be chmod 777, which is highly insecure. If I am using a shared host, which many of us are, it is not feasible for me to create an ftp login for all my users. I use session based security, and require sessions for all uploads, but if the folder is 777, anyone can just come along and browse it, and more importantly, bypass the session and write to it.

htaccess is not really suitable in my situation either, as it will use the browser popup for auth, rather than my login system and this is not consistent with the rest of the site. Once someone has logged into my site (i.e. authenticated against my db, and got a session/cookie), they should be logged in to all the areas they require access too. And how to maintain password resets etc between the db AND the htpasswd file?

Is there a way for me to use something like ftp_connect, or cURL to open a connection, possibly as a ftp user who only has access to this folder, and do some stuff like fopen(); fwrite(): or imagejpeg(); whilst the connection is open, and then close that connection?

Uploads Multiple Images

Oct 17, 2006

On my PHP form i have 5 upload fields each with a unique name. This is my first attempt at creating a form which uploads multiple images so all I would like is some advice on if this approach is way off what it should be and if it is, maybe a short explanation of how it should be done? For each upload field i have this PHP code: PHP Code:

$imgA = $_FILES['uploadimageA']['tmp_name'];

        if (!empty($_FILES['uploadimageA']['tmp_name'])) {
            if (move_uploaded_file($imgA, $targetpath . basename( $_FILES['uploadimageA']['name']))) {
                $chmodpath = $targetpath . basename( $_FILES['uploadimageA']['name']);
                chmod ("$chmodpath",0644);
                $imageisuploaded = true;
            } else {
                // error message would be here...

Where the 'uploadimageA' references the letter A, I would change to be 'uploadimageB', 'uploadimageC' and so on. Therefore the same code is duplicated down my page 5 times but each field has a different letter making the name unique. Is this ridiculously poor? By the way, it uploads the images fine.

Multiple File Uploads?

Jul 9, 2005

For a small website which will be used mainly to store images during a long trip, I am looking for an easy to use method to upload many (100+) images onto a webserver. Obviously, multiple file form elements is not realistic.

The next option I found, was the use of a java applet called jupload. This however requires a java runtime to be installed., Since this person will be travelling south/central america, and may not have the option to install anything on the computers, that's not ideal either.

Is there really no good alternative for multiple file uploads? It need to be able to select several (again 100+) image files in one go, and upload them all. Can the PhP FTP tools be used for this? I could not figure out how to create the client side for it. Is also seems to be able to use only one file box.
