#17958 [Com]: <input type=file> loses $_POST vars

ID: 17958 Comment by: marc@twisted-pair.de Reported By: ddp@deakin.edu.au Status: Open Bug Type: Apache2 related Operating System: Linux 2.4.18 PHP Version: 4.2.3 New Comment: I currently have got the problem of lost _POST-Vars even without the enctype=... stuff. All post vars are lost. Browsers: Mozilla/1.0, lynx OS: Debian Linux/PPC Server: Apache 2.0.40 PHP: 4.2.3/4.3.0(cvs) Is there any "workaround"? (e.g. downgrading Apache or PHP) Previous Comments: ------------------------------------------------------------------------ [2002-09-12 07:24:01] kalowsky@php.net updating version ------------------------------------------------------------------------ [2002-09-12 05:42:28] ichwilleineemailadresse@gmx.net The Bug still appears in PHP 4.2.3 ------------------------------------------------------------------------ [2002-08-26 10:12:39] arash@yalpani.de I have a similar problem using PHP 4.2.2 and Apache 1.3.23. But only the first value of the $_POST-vars gets lost. ------------------------------------------------------------------------ [2002-08-21 19:15:37] clindh@homenet.se I just encountered symptoms quite similar to what you report here. I lost the first field from my POST:ed data when I had enctype"multipart/form-data" encoding on the form - with default encoding it worked fine. I never lost all POST:ed values though; just the first one (which happens to be a hidden field, but PHP does not know that). I know this worked fine with the same browser (IE6) while we were running PHP 4.1, we recently upgraded. This is with PHP 4.2.2 and Apache 1.3.26 ------------------------------------------------------------------------ [2002-07-28 07:35:42] harry@ilo.de I could reproduce this Bug with Apache 1.3.23 and PHP4.2.1, 4.2.2 and 4.3.0-dev (2002-28-07), OS is WinXP Pro. All Form-Data using method=post is lost as soon as I add enctype="multipart/form-data" to <form>. It doesn't matter if there's a <input type="file"> in the form or not. The Bug does not always appear, but it seems to happen more often in php4.3.0-dev (~80%) than it was in 4.2.1 (~40%) or 4.2.2 (~60%), The code I used to test this: ------------------------------------------ <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>enctype-testpage</title> </head> <body> <?php # DEBUG echo "POST:<br>"; while(list($pkey, $pvalue)=each($_POST)) echo $pkey." = ".$pvalue."<br>"; echo "<br>GET:<br>"; while(list($pkey, $pvalue)=each($_GET)) echo $pkey." = ".$pvalue."<br>"; echo "<br>"; reset($_GET); reset($_POST); # /DEBUG ?> <form method="post" action="<?=$_SERVER["PHP_SELF"]?>" enctype="multipart/form-data"> <input name="xx" value="<?= $_POST["xx"] ?>"><br> <input name="xx" value="<?= $_POST["xy"] ?>"><br> <input name="xx" value="<?= $_POST["xz"] ?>"><br> <textarea name="yx"><?= $_POST["yx"] ?></textarea><br> <input type="hidden" name="b" value="z"> <input type="submit" name="s1" value="go"> </form> </body> </html> --------------------------------------------------- My file was called test.php and was therefore not the index-file of the directory. The Bug appeared with Internet Explorer 6 and Mozilla 1.0. Opera 6.01 was also affected but less than the others (only around 5% of my tries were buggy). Mozilla (~50%) is also less affected than IE (80-90%).
