Upload - Limited to 12 files

[MikeKohler]

I have a section of my website where logged in users can upload files to a set directory. None of the files being uploaded are very big, the biggest is 92 kb, and together the size is around 800kb. But there seems to be a limit on the number of files that can be uploaded, after 12 files nothing happens when a file is uploaded. No error message pops up, the file is just not there. Is there a limit to the number of files that can be uploaded to a folder?
Thank you,
Michael Kohler

Are all the files being uploaded at once or singly?
If all at once how are the files listed?
Have you hit a string length limit in the transfer request?
All guess work, I am afraid, without more information.

Thanks for the response. The files are being uploaded singly. It doesn't make sense from a size issue, I've uploaded files that are larger than 800 kb, it only becomes an issue when there are 12 files in the directory.

Does the upload script do any kind of file checking on the server?

This is the code that I use to upload the files:

<?php //Script 11.4 - upload_file.php

// Address error handling.
ini_set ('display_errors', 1);
error_reporting (E_ALL & ~E_NOTICE);

if (isset ($_POST['submit'])) { //Handle form.

// Try to move uploaded form.
if (move_uploaded_file ($_FILES['thefile']['tmp_name'], "./uploads/{$_FILES['thefile']['name']}")) {

include ("file_index.php");

} else { // Problem!

print '<p>Your file could not be uploaded because: <b>';

// Print a message based upon the error.
switch ($_FILES['thefile']['error']) {
case 1:
print 'The file exceeded the upload_max_filesize setting in php.ini';
break;
case 2:
print 'The file exceeds the MAX_FILE_SIZE setting in the HTML form';
break;
case 3:
print 'The file was only partially uploaded';
break;
case 4:
print 'No file was uploaded';
break;
}
print '</b>.</p>';
}
} // End of SUBMIT IF
// Leave the form and display the form
?>

is it possible that the nth file has the same 'name' as a file preceding it? and thus the move_uploaded_file call will overwrite the previous?

 

[MikeKohler]

No, I checked and that is not happening.

Hi, thanks for your help. I figured it out. When I upload, it calls a function that deals with the file. Since I have multiple folders, each folder has a seperate function. I called the wrong function, and the uploaded file was being sent to the wrong folder. I didn't notice it before, because I had manually placed the first files in this folder using Dreamweaver. I hope I didn't waste too much of your time.

add some debugging to the code, before the include. echo out the contents of the $_FILES superglobal and a directory read of the upload directory (ideally do this before and after the move_uploaded_files() call.

i still think there may be a file overwrite happening if you are not getting any other errors. try just checking with

clearstatcache();
if (file_exists('./uploads/'.$_FILES['thefile']['name']){ die ("stopped to prevent an overwrite");
