Hi, I had this same problem. I spent hours searching the web, but found nothing except this: ------ from http://www.php.net/manual/en/features.file-upload.php jason 09-Jan-2006 05:08 Regarding empty $_FILES and $_POST arrays when uploading files larger than post_max_size: Tucked away in http://us3.php.net/manual/en/ini.core.php#ini.post-max-size is this nugget: "If the size of post data is greater than post_max_size, the $_POST and $_FILES superglobals are empty. This can be tracked in various ways, e.g. by passing the $_GET variable to the script processing the data, i.e. <form action="edit.php?processed=1">, and then checking if $_GET['processed'] is set." This may seem like a bug. You'd expect something like UPLOAD_ERR_FORM_SIZE to be set. But you just two empty superglobals. I've seen it submitted to bugs.php.net twice and it's been marked as bogus both times. -------- I saw this, and realised that my MAX_FILE_SIZE hidden form element was missing. Inserting this fixed the problem immediately. My PHP version is 4.4.2. Hope this helps. Previous Comments: ------------------------------------------------------------------------ [2006-05-11 21:24:50] hostgeekz at gmail dot com I am having this issue on PHP 5.0.4, and PHP 5.1.4 Exactly the same as stated above, enctype="multipart/form-data" ------------------------------------------------------------------------ [2006-04-07 08:07:58] timecop at gmail dot com Yes this is still valid. whats worse, if enctype=multipart/form-data, NONE of the variables make it into $_POST.

Thank you. ------------------------------------------------------------------------ [2003-10-27 10:51:37] [EMAIL PROTECTED] Check your httpd.conf (probably in /etc/httpd/conf) if there's some directive that limits the maximum length of incoming data. See bug #22138 for detail ------------------------------------------------------------------------ [2003-10-27 10:47:18] jacknorton101 at hotmail dot com Description: ------------ The following code works in my local development environment (Win ME, Apache 1.3.2, PHP 4.3.2) but not on my host (RedHat 9, Apache 2.0.4, PHP 4.3.3). None of the form inputs defined after the <input type="file" size="40" name="userfile"> line are set in $_POST (all of those appearing before are). Therefore $_POST['submitimage'] does not get set. If I take out enctype="multipart/form-data", or replace it with "multipart/mixed" the $_POST variables are set, but the file is not available. The following php.ini directives are identical in both the local and host environments: File_Uploads = On Upload_Max_Filesize = 2M Upload_Tmp_Dir = (default) Post_Max_Size = 8M In my local environment Register_Globals is Off, and the host environment has them on. I have searched previous bug reports, and though I have seen similar problems, they all seem to be closed and rectified some time (over a year) ago, but my host is on release 4.3.3 - i.e. later than my dev environment. Thanks in anticipation, Jack. Reproduce code: --------------- .... if(!isset($_POST['submitimage'])) {.... <form action="<?=$_SERVER['PHP_SELF']?>" enctype="multipart/form-data" method="post"> <input type="text" maxlength="60" size="40" name="caption"> <input type="file" size="40" name="userfile"> <input type="hidden" name="MAX_FILE_SIZE" value="2000000"> <input type="submit" name="submitimage" value="Submit"> <input type="reset" value="Reset"> <input type="button" onClick="window.close();" name="noaction" value="No Action"> </form> .... <?php } elseif('Submit'==$_POST['submitimage']) { //process file .... Expected result: ---------------- I would expect the $_POST variables to be set, for example $_POST['submitimage'] should be set and allow the elseif clause to execute. Actual result: -------------- Only the $_POST variables defined in lines above the line: <input type="file" size="40" name="userfile"> get set. The ones below, including $_POST['submitimage'] do not get set. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26004&edit=1
