Bug #24404 [Com]: File Upload Failure

Edit report at http://bugs.php.net/bug.php?id=24404&edit=1 ID: 24404 Comment by: ryankam at hushmail dot com Reported by: catalin at ips-software dot de Summary: File Upload Failure Status: Bogus Type: Bug Package: Unknown/Other Function Operating System: Linux (mandrake 9.0) PHP Version: 4.3.1 Block user comment: N New Comment: Set Post Max like this: post_max_size = 14M and then just handle max file size in html and it will catch and throw an error. I dont know why 14m is a magic number but after testing in 5.3.3 it seems that is the fix. On winxp machine.

We would appreciate getting a populated $_POST even when the upload exceeds its limit. ------------------------------------------------------------------------ [2003-07-04 18:49:53] cynic@php.net there seem to be two problems here: * PHP does not signal the condition to the running script in any way. you just get empty $_FILES/$_POST arrays * the warning is not displayed, only logged, ignoring the display_errors php.ini setting. all you can do is enable track_errors and parse the $php_errormsg variable. a bit convoluted if you ask me. the first item is debatable, the other one sure looks like a bug. ------------------------------------------------------------------------ [2003-06-30 07:14:05] derick@php.net Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. Fix your php.ini settings, \"post_max_size\" and \"upload_max_filesize\" for example. ------------------------------------------------------------------------ [2003-06-30 07:12:33] catalin at ips-software dot de Description: ------------ Trying to upload files which exceed the post_max_size param from php.ini fails without any errors transmitted to the PHP script that handles the upload. This is the logged error. [error] PHP Warning: POST Content-Length of 11184886 bytes exceeds the limit of 8388608 bytes in Unknown on line 0 I did specify MAX_FILE_SIZE in the HTML form, before the <Input type=file ... block. The engine discards the download and gives no error. The $_FILES and any other server vars are completely empty; no error about the broken upload. php.ini: memory_limit = 48M post_max_size = 8M file_uploads = On upload_max_filesize = 8M allow_url_fopen = On Reproduce code: --------------- <FORM name='up' enctype='multipart/form-data' method='POST' action='<?php echo $PHP_SELF ?>'> <INPUT type='hidden' name='MAX_FILE_SIZE' value='5242880' /> <INPUT type='file' name='up_file' size='50' /> <INPUT type='submit' name='submit' /> </FORM> <?php if(!empty($submit)) { print_r($_FILES); phpinfo(); } ?> Expected result: ---------------- Since I tryied to upload a file which exceeds both the MAX_FILE_SIZE and the post_max_size I would have expected to find some sort of error in the $_FILES['up_file']['error'] or anywhere else in the PHP variables, but I found no such error(s). Actual result: -------------- No result whatsoever except the log: [error] PHP Warning: POST Content-Length of 11184886 bytes exceeds the limit of 8388608 bytes in Unknown on line 0 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=24404&edit=1
