ID: 62536 Comment by: Sjon at hortensius dot net Reported by: danny at tibibi dot com Summary: file uploads MAX_FILE_SIZE doesn't work as described Status: Open Type: Bug Package: Unknown/Other Function Operating System: Windows Server 2008 PHP Version: 5.4.4 Block user comment: N Private report: N New Comment: If you read the link I posted, you'll see that PHP _also_ checks for the defined MAX_FILE_SIZE and behaves the same as it would with max_upload_size @ini. So: PHP checks this too, but the client-side advantage isn't implemented in any browser (which is also described here: https://bugs.php.net/bug.php?id=40387) Previous Comments: ------------------------------------------------------------------------ [2012-07-12 17:15:01] danny at tibibi dot com Thanks for your comment. If php doesn't do anything with the variable, then why is it php returns error "2" in the $_FILES array when I set that variable, and upload a file that is smaller than the max_upload_size in the .ini file but larger than the MAX_FILE_SIZE variable I post? ------------------------------------------------------------------------ [2012-07-12 13:57:07] Sjon at hortensius dot net This feature is meant for clients (eg. browsers), but it seems your browser doesn't implement this feature. PHP doesn't do anything with this variable More info @ http://stackoverflow.com/questions/1381364/max-file-size-in-php-whats-the-point ------------------------------------------------------------------------ [2012-07-11 17:10:07] danny at tibibi dot com Description: ------------ The documentation for handling file uploads, http://us3.php.net/manual/en/features.file-upload.post-method.php states that when declaring a hidden field named MAX_FILE_SIZE, if the file submitted is larger, then the user will not have to wait longer to be told that the file was too large. <?php if (isset($_POST['MAX_FILE_SIZE'])) { echo $_FILES['file1']['error']; } ?> <html> <body> <form action="/test.php" method="post" enctype="multipart/form-data"> <input type="hidden" name="MAX_FILE_SIZE" value="100" /> <input type="file" name="file1"> <input type="submit" value="submit"> </form> </body> </html> Actual result: -------------- The complete file gets uploaded however big it is, and the result shows: 2 This confirms that MAX_FILE_SIZE worked, and the file was too large, but it did not stop processing the request after 100 bytes were processed. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62536&edit=1
