[PHP] $_POST suddenly empty; $_GET and _$REQUEST fine
I've got an Apache 2.2.3 server running PHP 5.2.6 on top of FreeBSD 6.2. It's worked quite well for over a year now. However, as of some time last night, phpBB broke; upon investigation, I realized that the problem was that $_POST was never getting populated, even on properly formed HTML forms. Testing this to try to find the issue, I used the following script: ?php print Testvar: . $_POST['testvar'] . br/\n; ? form method=POST action=http://www.newmars.com/test.php name=formname enctype=multipart/form-data input type=text name=testvarbr/ input type=submit value=Submitbr/ /form It works like a charm on a different machine with an essentially identical config (it's a newer version of FreeBSD, but that's about it); however, it never displays the contents of $_POST['testvar'] on the machine that suddenly quit functioning right last night. Meanwhile, the rest of PHP seems to be working fine, as the phpBB forum is accessible in a read-only fashion. I've searched all over, and done things like restarting Apache; checking phpinfo() for the POST data (it's not there on the broken server, but it is on the functional one); writting a quick Perl script that took POST input to verify that my browser was sending such data properly (it is); and scouring the Apache/PHP error logs. The worst part is, I didn't touch the config at all between when it worked and when it didn't. So now I'm at a total loss as to what could be causing this, or how I should go about troubleshooting. Any thoughts on this would be greatly appreciated.

?
form method=POST action=http://www.newmars.com/test.php
name=formname enctype=multipart/form-data
input type=text name=testvarbr/
input type=submit value=Submitbr/
/form
looks like you already fixed it.. works fine for me on your server:
array(1) { [testvar]= string(2) er } NULL
(then all the phpinfo())
i posted er on the form at bottom..
Seems to be working for me also.
I wish it were a real fix. I had switched the print statement back to
use $_REQUEST after I pasted the code in my message, just to be 100%
certain that I wasn't losing it, and didn't think to switch it back
before I left work for the evening - somehow I didn't anticipate you
guys actually using the live form. :-P
Did you check the apache logs or the php error logs?
Apache logs show no errors at all. The PHP error log is more
interesting - I turned on logging to /var/log/php.err once I started
trying to diagnose this, and that file has yet to be created. At one
point today, I intentionally wrote in a syntax error to a PHP script,
and the error message printed out into the Apache log, so at this
point I'm assuming that if PHP were going to give me a relevant error,
it'd be there.
How about disk space on the server location where it is storing it's temp
files for the server?
I've seen something similar when disk space was nil after some scripts ran
amok.
Temp files should be on /, which is only at 41% of capacity. Even if
it's /usr, that's at 90%, not 100%.

touch /var/log/php.err chown apache:apache /var/log/php.err adjust apache with your webserver user/group (check httpd.conf) though I doubt anything will show up there. Well, done anyway, just in case. Do you have mod_security enabled in apache? Maybe it's catching something it shouldn't. Nope, unless grep -iIR security * in /usr/local/etc/apache22 is lying to me. ;-) Alex This message was sent using IMP, the Internet Messaging Program. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

and if you remove the multipart/form-data from the form?
I actually added it in during my testing, since I'd seen some bugs
from 2005 or so related to that. I hadn't specified an encoding
previously.
any includes in that script that script?
None.
any .htaccess rewrites?
Hmmm, that's interesting: this is present in the docroot for www.newmars.com:
IfModule mod_rewrite.c
RewriteEngine On
RewriteBase /wordpress/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wordpress/index.php [L]
/IfModule
mod_rewrite is indeed enabled in the main HTTP config (we use it on
other domains hosted on the box). /wordpress does exist on that
virtual host, but I admit, this is one area that I'm not super-well
versed on. Are there known issues with POST data and rewrites? It
seems sort of odd, since that .htaccess hasn't changed since 3/8/08,
but at this point I'll accept just about any solution. :-)
error_reporting(E_ALL | E_STRICT) set?
It is now...but the whole damn domain went down. WTF

OK, so first off, this outage is apparently something confined to
the XP laptop I'm currently sitting at. Remind me to go check for
spyware after I send this...
That said, I was checking with the other guy who has root on the box
before I rebooted the whole server, in case it was some bizarre
caching issue, and he asked that I remove the following line from
httpd.conf before I did so, since apparently he'd added it around the
time that PHP had eaten itself:
LoadModule python_module libexec/apache22/mod_python.so
Strangely enough, after rebooting Apache, it worked like a charm. The
only possible explanation that I can think of - since mod_python and
libphp5 shouldn't conflict - is that this line was immediately
preceded by:
LoadModule php5_modulelibexec/apache22/libphp5.so
...and Apache did some sort of dumb parsing thing. Though I guess that
wouldn't explain why PHP was only partially broken...
So at this point, I'd like to thank all of you for your extremely
rapid and thorough responses, and say that if anyone cares to probe
this further, I'm open to testing things out...but if we just want to
chalk it up to random weirdness, I'm OK with that, too.

[PHP] Re: HTML E-Mail
Damn, what a flame war I've started! I had no idea... In any case, Richard: I agree that HTML e-mails, generally speaking, suck. The most HTML I **personally** think should be in an e-mail is a quick link to a web page, maybe a bit of text coloration/sizing for emphasis. However, **professionally**, I'm looking at something completely different. I run a small web services business looking for any form of cash possible, and a local portal site has offered to promote on their site an HTML e-mailing system that we create -- and they have customers *begging* for it. While I as an individual may despise HTML e-mail, I as a businessman cannot turn down such an obvious revenue-generation stream, especially in today's economy. I came to the list looking for technical help because it's something that I need to do, not something I want to promote. Whatever my motives may have been, though, there's no reason to launch such a tirade on the subject on-list -- if you want to bitch and moan and flame, it's just as easy to do off-list. Please, please, let's kill this thread and all the animosity going with it -- *especially* since I've been kindly pointed in all the directions needed for technical help.
