#22427 [Com]: Missing Form Post Data

ID: 22427 Comment by: emil dot hall at gamereactor dot se Reported By: jroland at uow dot edu dot au Status: No Feedback Bug Type: *General Issues Operating System: Windows XP / 2000 PHP Version: 4.2.3 New Comment: We must be talking about several different bugs here. But the bug where some fields are missing from $_POST is NOT a PHP bug, it's all Internet Explorer's fault. This HTML reproduces the bug in IE6: <form method="post" action="whatever" enctype="multipart/form-data"> <input type="text" name="field1" value="1"> <input type="text" name="field2" value="2…"> <input type="checkbox" name="field3" value="3"> <input type="submit"> </form> The weird character in the second input field will mess up IE's submit. Characters that confuse IE include: three-dots-as-one-char … aka chr(133) the long dash – aka chr(150) and the double quotation mark “ aka chr(147) All very common when you copy&paste from MS Word, just like Egil said. A packet sniffer reveals the broken POST request: (some irrelevant headers have been removed) POST /whatever HTTP/1.1 Content-Type: multipart/form-data; boundary=---------------7d6399243401fe field1" 1 ---------------7d6399243401fe Content-Disposition: form-data; name="field2" 2. ---------------7d6399243401fe-- Submit the same form with Firefox and the difference is obvious: POST /whatever HTTP/1.1 Content-Type: multipart/form-data; boundary=------------------41184676334 ------------------41184676334 Content-Disposition: form-data; name="field1" 1 ------------------41184676334 Content-Disposition: form-data; name="field2" 2. ------------------41184676334-- Previous Comments: ------------------------------------------------------------------------ [2006-08-29 18:16:32] egil at egil dot net Sorry for flooding this one, but I have noticed something else that I think is important here. I am not always getting this bug with IE6 either, it depends on the text I submit into one of my textarea or text fields. If one of them containts a double quotation mark of the type you get if you press shift-2 within Word (not the standard double quotation mark, which works fine) and copy/paste the text into a textarea or textfield. Please contact me if you need a better explaination and/or testdata. ------------------------------------------------------------------------ [2006-08-29 18:04:31] egil at egil dot net Forgot to mention that I am having this problem with PHP 5.1.4 running on FreeBSD and Apache 1.3.34. ------------------------------------------------------------------------ [2006-08-29 17:57:53] egil at egil dot net I am also getting the exact same problem as "rossi at nelis dot fr" and "gregory dot boyer at limbas dot com". I am not able to reproduce this problem in other browsers than IE6 posting using multipart/form-data as enctype. ------------------------------------------------------------------------ [2006-08-11 15:43:05] gregory dot boyer at limbas dot com we experience the same trouble as "rossi at nelis dot fr" A form is send with POST method and with enctype multipart/form-data, in the target page the first field is missing. It is only occuring in IE6.0, and only with the enctype ------------------------------------------------------------------------ [2006-06-07 13:32:25] rossi at nelis dot fr I confirm to you that i reproduce this problem with PHP5. The first field (TextArea) is missing when i read $_POST with var_dump($_POST). This bug exists only when i'm using Internet Explorer (6.0 for my version), not with Firefox 1.5. I'm searching for a solution. May be i have to create 2 dummy hidden fields :(:( Please send me an email if you find the solution. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
