Basically when I have more than about 25 file uploads in one form, the PHP $_FILES array is cropped to the first 25 entries (0-24), which is incorrect. It should have all 31.
This only happens on one particular server. Apache with PHP. I’ve tried it on two other servers and they seem to allow all 31.
Could this be caused by some configuration option in Apache? Or is it more likely a configuration issue in PHP?
The only thing I can think of is possibly the LimitRequestFields apache directive, but this should throw an error rather than just crop it to the first 25. Right?
I know that having so many File fields in one form is bad practice, however this is a necessity due to the functionality required for this particular page. I can't work around this.
Any help with this problem would be greatly appreciated.
The below HTML demonstrates the problem I am having.

That "25 max files" and "happens only on a specific server" seems to indicate some configuration/security measures on that server.
And "25 max uploads" is the default configuration of the suhosin PHP extension -- see the suhosin.upload.max_uploads configuration directive.
That extension is installed by default (for security reasons) on some Linux distributions -- Ubuntu provides it by default, for example, if I remember correctly ; you can check if it's installed/enabled in the output of phpinfo().
Check out the File Uploads section of the ini file directives.
There is a max_file_uploads limit setting available since PHP 5.2.12 which you might want to look into adjusting if you are using that version or above.
As well, the upload_max_filesize is a total maximum for all uploaded files combined, so it's possible that you could be hitting a limit there, although from the description it sounds more likely that a max_file_uploads limiter is the problem.
PHP puts uploaded files into a temporary directory. So you can confirm if the issue is with PHP or with Apache by checking to see if the extra 6 files are in that temporary directory.
What I would do is get the location of the first file, and then run a loop to echo out all of the files in that directory. If it is 31, it's PHP, if it's 25, it's Apache.
If looking at the Suhosin configuration settings doesn't work. Try checking the upload_max_filesize and post_max_size options in the php.ini.
Have a look at the LimitRequest* directives:
http://httpd.apache.org/docs/2.2/en/mod/core.html#limitrequestbody
why not use move_uploaded_file it's work just try and add path in array and execute in this function if not work? copy move_uploaded_file (number of files) this is not good but its work
just try
$file1 = $_POST['file1'];
$file2 = $_POST['file2'];
$file3 = $_POST['file3'];
$file4 = $_POST['file4'];
$file5 = $_POST['file5'];
$file6 = $_POST['file6'];
$array = array($file1,$file2,$file3,$file4,$file5,$file6);
if(isset($_POST['submit']))
{
for($i=0;$i<count($array);$i++)
{
$dir = $array[$i];
$uploaddir = "dirfiles/";
$uploadfile = $uploaddir.$_FILES['file1']['name'];
move_uploaded_file($_FILES['file21']['tmp_name'],$uploadfile);
$uploaddir = "dirfiles/";
$uploadfile = $uploaddir.$_FILES['file2']['name'];
move_uploaded_file($_FILES['file2']['tmp_name'],$uploadfile);

How can I select a file on my local machine using an html file on my lighttpn webserver and start a shell script with the selected file as input? Lets say i have a script for unpacking an archive with unrar. First I visit the website on my webserver and choose the file. The "unpacking-script" should be started with the path to the file as input. Lets say the output is always the same. This is a very simple html file with file selection. But I don't know how to start the script with the file as input.
<html>
<body>
<form action="upload_file.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>
</body>

My source code is to print upload SWF file tmp_name ?
<?php
echo json_encode($_FILES);
?>
<form method="POST" action="#" enctype="multipart/form-data" novalidate>
<input type="file" id="image" name="image" />
<input id="send" type="submit" name="data" value="Submit" />
</form>
But result i'm getting
{"image":{"name":"file.swf","type":"","tmp_name":"","error":1,"size":0}}
I have tried image uploading method no use on that !
{"image":{"name":"file.swf","type":"","tmp_name":"","error":1,"size":0}}
^^^^^^^^^
This error isn't specific to Flash at all. You'd run into the same issue with other formats as well.
Error 1 is UPLOAD_ERR_INI_SIZE. It means that the file you tried to upload was larger than your server's maximum upload size (upload_max_filesize), so the server didn't accept it.
Change this configuration value, or upload a smaller file.
<form action="uploads.php" enctype="multipart/form-data" method="post">
<?php
if(!empty($message)){
echo "<p>{$message}</p>";
}
?>
<input type="hidden" name="MAX_FILE_SIZE" value="1048576" />
<label for="something">Please, upload your file</label>
<input type="file" name = "file_upload" id="something"/>
<input type="submit" name="submit" value="Upload" />
</form>
</body>

I changed post_max_size = 100M, max_file_size was already 64M. Problem is when I run the code and upload more than 20kb then first time it gives error no. 3 (partial upload problem) and then stop working. I have to restart php to do other thing. Please help..
In your php.ini file, change this variable upload_max_filesize to whatever max_uploaded_size you wish to have.
But remember, to keep your post_max_size greater than or equal to upload_max_filesize.
For more info, see this answer.
PHP change the maximum upload file size
Is it possible with codeigniter, or even at all, to have only one input field that allows a user to select multiple files to upload. So basically you have
<input name="files" type="file">
rather than
<input name="file1" type="file">
<input name="file2" type="file">
<input name="file3" type="file">
I currently know how to implement the latter but think the former would be a cleaner model.
Have you even looked into PHP manual?
<form action="file-upload.php" method="post" enctype="multipart/form-data">
Send these files:<br />
<input name="userfile[]" type="file" multiple=""/><br />
<input type="submit" value="Send files" />
</form>
you access it in PHP as $_FILES
Your input has to be like this (so, you can select multiple files at once)
<input multiple type="file" name="files[]" />
Notice multiple attribute but not supported by all/old browsers.
An Example here and also take look at this tutorial.
I'm having a problem uploading files in PHP. When I submit, $_FILES[] is empty. I feel like this is such a n00b question :/
My form:
<form method="post" action="uploadfile.php">
<input type="hidden" name="MAX_FILE_SIZE" value="300000" />
Image: <input name="ImageFile" type="file" /><br />
<input type="submit" value="Add Image" /><br />
</form>
Relevant php.ini:
;;;;;;;;;;;;;;;;
; File Uploads ;
;;;;;;;;;;;;;;;;
; Whether to allow HTTP file uploads.
file_uploads = On
; Temporary directory for HTTP uploaded files (will use system default if not
; specified).
upload_tmp_dir = "c:\php5\upload\"
; Maximum allowed size for uploaded files.
upload_max_filesize = 300M
c:\php5\upload\ is writable by IUSR_HOSTNAME
Any thoughts on what else I should check?
Make sure your form tag has this attribute: enctype="multipart/form-data"
Without it the files will not get uploaded.
