Hi all,

I have a seemingly strange thing happening here. I have a contact form
on one website that works perfectly and that same form with appropriate
changes, results in an error message during a check of a random number
(created with mt_rnd() ) on the other site. Both sites are located on
the same remote servers.

Win 7, PHP 5.3.5, XAMPP local server, standard Unix remote server:

Please consider the following:

Complete form consists of three .PHP pages; no HTML. Entry form, check
page, mailto() page; pretty standard stuff in that way:

================
WORKING CODE ON REMOTE SERVER:

Setting the code on landing page:
$_SESSION["d"] = $d;
--------------------

$code= $_POST["code"];
if($_SESSION["d"] !== $code) {
echo "<br />You did not enter the correct code: Script halted, ALL
data destroyed.<br /> you'll have to go back to the website and start
over.<br />";
die("Script HALTED, data destroyed");
session_destroy();
exit();
}
RESULT:
page throws no error either with local or remote server: Message is sent
successfully.

===============================

NON-WORKING CODE ON REMOTE SERVER BUT WORKS ON LOCAL HOST:

Setting the code on previous page:
$_SESSION["d"] = $d;
----------------------
Page with problem:
$code= $_POST["code"];
if($_SESSION["d"] !== $code) {
echo "<br />You did not enter the correct code: Script halted, ALL
data destroyed.<br /> you'll have to go back to the website and start
over.<br />";
die("Script HALTED, data destroyed");
session_destroy();
exit();
}

RESULT:
[Gets stuck on the second page of the form where PHP sanitize/validation
happens; never makes it to last page with the mail() function]:

using code : 487-535175 <----------- WHICH IS CORRECT CODE
You did not enter the correct code: Script halted, ALL data destroyed.
you'll have to go back to the website and start over.
Script HALTED, data destroyed
================

Can you spot any differences there? The local server throws NO error,
notices or warnings. But the Remote Server stops cold on the second
page, indicating the code is wrong. But it's not; I can see the code;
it's correct. But it seems to never be seen as correct by my Remote
Server while my Local Server accepts it perfectly.

What really gets me is it works on one site and not the one I'm trying
to perpetuate the code to. OH, and both sites are on the same Remote
Servers at Netfirms.com. Separate accounts of course.
I'm not using rewrites, no php changes on the Remote Server; both
sites are on the same server.
Any thoughts or ideas what I might be doing wrong or where else I
should be looking?

TIA,

twayne`

Without posting the entire code, any answer would be just a guess.

What is the error message as well?
What specific behavior where you expecting that you are not getting?

When I have had similar issues running phpinfo() on both sites usually
reveals a different php envoironment and gives a clue as to where it's
being set as well.

Ineptocracy

(in-ep-toc’-ra-cy) – a system of government where the least capable to lead are elected by the least capable of producing, and where the members of society least likely to sustain themselves or succeed, are rewarded with goods and services paid for by the confiscated wealth of a diminishing number of producers.

I'm not very good at reading PHPinfo() but the two PHPinfo() displays
(my local Apache server and Remote Server) are the same in all the areas
that would seemingly have anything to do with PHP; same paths, same
dates, same revs, etc. and in its entirety also. I purposely keep my
local PHP version the same as my Servers.

Thanks ... I ran thru the effort again, just to be sure.

There is no Server message; the error is my own code taking the "bad
code" path and halting the script, so it's my own code that's the
problem, OE something different at the Server. I just did a PHPinfo()
comparison to my local server and they're darned near identical, so why
it succeeds in the other script and not in this current script on a
different sit on the SAME server is beyond me!
Yesterday I ported the complete, untouched code from the working
site to the problem site, and got the same identical problem of the
script halting due to taking the wrong fork in the IF statement! I'm at
a complete loss. Guess I'll have to go thru it more and look for copy
problems et al.

I'm no guru with PHP but this still has me real confused.
The reason I don't post complete codes are, I'm not allowed to for
security reasons. Changing them around to be able to post them would
destroy their integrity for posting here due to the stuff I'd have to do
to be able to post it in the clear. It's also a LOT of code; every page!

Any thoughts, comments are still welcome.

Regards,

Twayne`

You may consider checking the actual values of $code and $_SESSION['d']
immediately before the if statement (if you don't have a debugger at
hand, just use a simple var_dump()).

BTW: calling session_destroy() after die() was executed doesn't have any
effect. You'll want to swap both lines and remove the exit().

It's interesting, but I did. A rev back I had an echo for "code" and
Session(... and it prints them just before it throws the error message.

THAT is wise advice! Thanks I'll do just that; thanks for pointing it out.

I was thinking more of stuff like magic quotes, charsets and other minor
things that might affect how the code was interpreted.

The other place I routinely look, because I can, is apache error logs.
Thats where PHP errors tend to popup up if not displayed onscreen.

HUH! You seem to have driven something home! I fixed up the changes you
recommended, tried it, and drew a 500 Error from the server. Put it back
the way it was and still getting a 500 error. It's not definitive, but
it suggest something went seriously wrong.
Thanks for even that much,

And both had exactly the same value (a leading or trailing space, for
instance, make a big difference here) and the same *type*? Then the
body of the if statement won't be executed.

$code= $_POST["code"];
echo "<pre>";
var_dump($_SESSION["d"]);
var_dump($code);
echo "</pre>";
if($_SESSION["d"] !== $code) {
echo "<br />You did not enter the correct code: Script halted, ALL

You need to make sure that both variables are of the same *value* and
*type*. Another way to check would be to change !== to != (or <>). The
only way your branch gets executed is if they do not match both *value*
and *type*.

What are you getting at? I do not see how a $_POST element could ever be
*not* a string, and the result of “!==” can be false even when the two
operands *are* of the same type. And the code must be a string here (it
contains “-”), so $_SESSION['d'] would be a string.

The difference is perhaps in the session not being started or recognized on
one PHP host, but on the other. If the session is not started, it could be
that session information cannot be written to the filesystem; if the session
is not recognized, it could be that the session cookie is not set on the
client-side due to user settings.

ISTM there still is not enough information in the posting; for example, the
part that *sets* $_SESSION['d'] is missing.

The OP should take heed of

<http://www.catb.org/~esr/faqs/smart-questions.html>

and stop wasting everybody's time with guessing games.

GOT IT! Finally.

Turns out my php.ini for my remote site was damaged. I've been running
around the pole for a week or more with them, getting various answers,
including it was my own fault and they won't help people with coding.
Jeezum Crow!
Everything was pointing to my server host, and not me, so: Today I
got fed up enough to try a chat, and a phone call if that didn't help.
Just goes to show: The chat tech asked me to hold while he checked
my accounts and a few seconds later was back, problem solved!! I
learned long ago to not give Support departments a chance to push things
back on me and just keep trying until you get the right tech or
supervisor or whatever. How one guy could look at whatever he looked at
and fix it right away and the others couldn't, well, speaks volumes
about support departments.

Thanks for all the excellent responses and attempts to assist. This is a
great ng!

Best Regards,

Twayne`

True, I forgot about that. But in this case you would not use a simple
comparison.

I think javascript is probably the ugliest language I have ever had to
program in really. Even worse than PHP.

By trying to make it 'easy for stupes' they make it very hard for people
who understand exactly what they want it to do, by hiding the means by
which it is to be done.

Trolling again, I see.

No, I didn't suggest what someone else said, because his was just a guess.

I prefer to diagnose the problem and give a *CORRECT* answer - not play
guessing games.
