Undefined Index notices

[Craig Morrison]

I'm getting this:

[client 192.168.5.50] PHP Notice: Undefined index: D1 in
/var/www/html.....

From this line of code:

$id_option = $_POST['D1'];

Which is posted by this:

<form target="_blank" method="POST" action="mailchart.php" name="mail_data">
<input type="hidden" name="D1" value="<? echo $id_option; ?>">
<input type="submit" value="View Chart"></p>
</form>

My question is why?

I *am* getting the correct value for $_POST['D1'] and at this point in
time am really quite confused because that notice is getting thrown.

[root@... ~]# php -v
PHP 4.3.11 (cgi) (built: Nov 8 2005 06:24:40)

[root@... /]# uname -a
Linux ... 2.6.12-2.3.legacy_FC3 #1 Sun Feb 19 10:47:10 EST 2006 i686
i686 i386 GNU/Linux

Thanks..

Have you checked this, i.e. with print_r($_POST) or var_dump($_POST)? In
such cases I usually try this first; if $_POST['D1'] is set at the top
of the script you might find out where it gets lost.

The question is, if it's invalid how come I am getting the correct value
that is POSTed to the script?

That's a pretty moot question, unless you think magic is causing it.

Consider it a flaw/bug in your construction. Markus' suggestion might get
you some insight into what might be the problem.

How is it moot?

A form posts the value for D1 to a script, script looks for the value of
D1 and gets it. PHP raises a notice that D1 is undefined.

I don't understand how I am getting the value that is posted to the
script if the index is undefined.

Is it really that difficult for someone to explain this?

As a follow up, print_r($_POST) yields:

Array
(
[D1] => 3
)

And I still get the notice..

How is it moot?

Well, I can't see how PHP would get the value, if the index was invalid or
non-existing.
A form posts the value for D1 to a script, script looks for the value of
D1 and gets it. PHP raises a notice that D1 is undefined.

I don't understand how I am getting the value that is posted to the
script if the index is undefined.

Is it really that difficult for someone to explain this?

Yes, because in all likelyhood, that is not what is happening.

Arrays and forms are so commonly used that, if it was a bug then it would be
reported all over the place.

I didn't say that it was a bug..

I'd yell louder if I thought it was. :-)

But I am getting the correct value, as you can see from the follow up
that I posted which does a print_r..

Sorry, if what you say is happening, really is happening, then it is a bug,
and since you didn't take Markus seriously, I assumed you did think it was.

You must be doing something or making assumptions that you consider
unimportant to tell, because it doesn't make sense. Are you sure you are
not seeing the notice *before* submitting the form, or subsequently do a
redirect, or do some fiddling with the _POST-array elsewhere?

You shouldn't make assumptions, that is a fatal flaw. You assumed that I

I am not making any assumptions, just writing code according to the
documentation. I gave the HTML that posts its results already..

These are the first 3 lines of the script that gets posted to..

<?
include 'inc/config.inc.php';
?>

The notice is generated in config.inc.php, which follows...

<?
// define query titles
$id_text[1]="Group Total Sent &amp; Received";
$id_text[2]="EU Total Sent &amp; Received";
$id_text[3]="EU Total Sent";
$id_text[4]="EU Total Received";
$id_text[5]="EU Sent By User";
$id_text[6]="EU Received By User";
$id_text[7]="US Total Sent &amp; Received";
$id_text[8]="US Total Sent";
$id_text[9]="US Total Received";
$id_text[10]="US Sent By User";
$id_text[11]="US Received By User";
$id_text[12]="All Domains";

// define view names
$id_view[1]="GroupTotal";
$id_view[2]="EUTotal";
$id_view[3]="EUAllSent";
$id_view[4]="EUAllRcvd";
$id_view[5]="EUSent";
$id_view[6]="EURcvd";
$id_view[7]="USTotal";
$id_view[8]="USAllSent";
$id_view[9]="USAllRcvd";
$id_view[10]="USSent";
$id_view[11]="USRcvd";
$id_view[12]="AllDomainsTotal";

// define column styles
$fc_col_styles['TOTAL'] = 'no';
$fc_col_styles['Total'] = 'no';
$fc_col_styles['SENT'] = 'no';
$fc_col_styles['Sent'] = 'no';
$fc_col_styles['RCVD'] = 'no';
$fc_col_styles['Rcvd'] = 'no';
$fc_col_styles['Month'] = 'mo';
$fc_col_styles['MONTH'] = 'mo';
$fc_col_styles['User'] = 'us';
$fc_col_styles['USER'] = 'us';
$fc_col_styles['MBytes'] = 'mb';
$fc_col_styles['MBYTES'] = 'mb';

// set default values
$id_text_count = 12;
$id_option = 1;

// determine what view we are querying
if ($_SERVER['REQUEST_METHOD'] == 'POST')
$id_option = $_POST['D1']; // <=== DING we have winner, notice gets raised
else if ($_SERVER['REQUEST_METHOD'] == 'GET')
$id_option = $_GET['D1'];

if (($id_option == 0) || ($id_option > $id_text_count)) {$id_option = 1;}
$selectID = $id_view[$id_option];
?>

As you can see, there is nothing but good php there.

Now, here's where I get pissed off. You all assumed that I was just
pissing in the wind. I gave a good explanation of what I was doing
before and this code tells you nothing more.

Next time, ask for answers before being an ass and assuming you are
working with a n00b..

Sorry I couldn't be more sensitive in my wording, but I think you are being
a bit touchy. For the record, I didn't think you were a n00b, just one of
those guys with an infinite faith in their own infallibility, who
apparently get all huffy at the mere suggestion that they made an error.

If you find it to be some funky bug in PHP, then I will unreservedly
apologize for anything you find fit. Alternatively when you find it to be
some banal mistake in your code, I hope you'll find it in you to forgive my
bruteness.

Touchy? I don't think so.

Is there any error in the code? If there is, by all means point it out.
That *is* the point behind posting it.

You seem to be on the track that I am trying to find fault here, which
is an error. I am not. So get over that.

I am simply trying to understand the behavior.

If you find it to be some funky bug in PHP, then I will unreservedly
apologize for anything you find fit. Alternatively when you find it to be
some banal mistake in your code, I hope you'll find it in you to forgive my
bruteness.

I still don't have an answer to the original query though.

As it stands, the app works and I may very well be being quite pedantic
about the whole mess but I would like some insight as to why the notice
is thrown. Which was the whole point behind this thread.

I showed the code that was throwing the notice and you (or anyone else)
have shed no light on the problem. I don't know what else I can do or
show to make it any clearer what is happening.

Maybe we both need to steer clear of the fan.

I don't understand why you think there is a "behavior". There is nothing

oddity that everybody else is missing.

You present your conclusions of what is happening and pieces of code you say
is involved. No offense meant, but I can't take that as certainty. I really
don't know any other way of putting it than, you must have overlooked
something, doing something or making assumptions that you consider

Message-ID: <wL******************************@insightbb.com> from Craig
Morrison contained the following:

if ($_SERVER['REQUEST_METHOD'] == 'POST')
$id_option = $_POST['D1']; // <=== DING we have winner, notice gets raised

Dumb question. You get the notice /after/ the form is posted?

Have you tried
$id_option =(isset($_POST['D1'])? $_POST['D1'] : "";

Why don't you just say that you don't know?

Or is it that you just feel a need to be verbose for no reason?

Here is the entire mess of code.. You tell me why the notice is thrown
if you can, otherwise shut the fuck up.

Oh, sticks and stones Craig, I am too old to care about your huffing and
puffing. And you are free to ignore anything I say.

The notice get thrown because there is an undefined index, just as the
notice says, but I can't tell you the exact circumstances. For that, I
would have to look over your shoulder, and see exactly how the things are
used and what comes out of it, and not just the things you find relevant to
tell. If it was visible from that, you would probably have seen it.

What I do know (or atleast put my reputation on the line for), is that if
the form posts the D1 value, as you say it does, then there is *no way*
that $_POST['D1'] is generating a notice. Period.
That is why I said you should treat it as a bug/flaw somewhere in your
construction, because effectively it would mean that you had an unhandled
state. But from your code you posted, I can see that you verify the value
afterwards, so it is not critical.

What Geoff suggest (using isset before accessing the value) lets you decide
what to do in cases where the value is not set. That will remove the
clutter from your log-files.

[snip code]
Ok, seen it.

Just a few things.
What is the exact full message (notice) you get.
How is the index.php page initially accessed. (get/post, args)

>Here is the entire mess of code.. You tell me why the notice is thrown

I tried setting this up on my server. When I browse to the
directory it's set up in, I get the undefined index notice
*BEFORE* the form appears (and I don't submit the form at all).

Unless I am invoking it incorrectly (is index.php supposed to be
called from ANOTHER form?) you're not taking into account that
config.inc.php is called just to throw up the form as well as
for submitting it.

I also get database errors because your queries don't work too
well on an empty database I pointed the page at. I don't need
your tables to reproduce the problem.

Gordon L. Burditt

[Richard Levasseur]

Gordon's thought is the same as mine. The only reason I can see it
raising a notice is if it is accessing the index when no data was
post/get'ed to the web page, which would be the case when the form
first appears. Simply use one of the previous replies which suggests
using isset().

You might understand that people will not take their time to answer your
questions if you stick to this style of posting. Also keep in mind that
newsgroups are archieved by Google, and thus everything you write will
be accessible in the future for anybody having any interests about your
personality, i.e. recruiters of companies where you apply for a job.

http://groups.google.ch/groups/profi...DuwKz324rebT9g
shows that you are quite new to newsgroups; you might want to read some
pages on netiquette. (I remember to have made some postings I am not
proud of when I first started to post to newsgroups, so I know what I
write about.) If you think some people are being rude in their comments,
then keep in mind that it is you asking for help, and they tell you that
you do this the wrong way - being told about the rules of usenet is a
form of help you should appreciate. If you want to get help on your
problems for free, you have to respect those people reading and
commenting your posts.

[snipped a lot of code]
I have left *nothing* out, so now, if you or anyone else can please tell
me why the notice is thrown.

I write this during my time that I am not paid for by anyone. Nobody in
this group has the duty to care for your problem. So instead of posting
either no code at all or the "entire mess", it might be a more
successful approach to track down the problem to it's essential parts.
Write a script only with the essential functionality, i.e.

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST')
$id_option = $_POST['D1'];
else if ($_SERVER['REQUEST_METHOD'] == 'GET')
$id_option = $_GET['D1'];
print_r($_POST);
?>
<html>
<head></head>
<body>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<input type="hidden" name="D1" value="<?php echo $id_option; ?>">
<input type="submit" value="View Chart">
</form>
</body>
</html>

Now if the output of print_r shows that $_POST['D1'] is set, but line 3
still throws a notice, then your question is correct. In this example
you find that the notice is thrown at line 12 in the case that the form
has not been posted yet.
Maybe this shows your problem, otherwise add more parts of your code
until the problem occurs. You can also remove parts of your
functionality until the error disappears, or var_dump() the variables
step by step.
At the end, you either find your mistake yourself, or then you know the
appropriate question to ask, and have the appropriate code to post.

Yes this is a lot of work, but it makes a base for friendly people to
help you. Alternatively you can hire some PHP crack to solve your
problems, but you won't get them solved for free if you keep shouting at
the people you expect help from!

It doesn't make people shut up either. :)

To be fair, his original post was quite polite.

When going head first into a mass of people from widely different cultures,
many trying to convey their message in a foreign language, then I think
some initial conflicts is what can be expected, regardless of the person.

And people change. If someone made some mistakes and they learned from them,
then that's a sign of a very good quality in a person.

IMO, people who don't understand that, are not worth pleasing or working
for.

I think his basic problem was, that he didn't expect help. In his mind, his
scripts didn't have problems, rather PHP had a strange behavior.
If only he had put a little effort into trying to understand what we were
trying to say. I thought your first suggestion was a clear and polite hint
that he should track down the problem in his code.

Anyway, it's not like one can demand what one wants, only hope to get what
one needs.

Yes... I was actually argueing with people trying to tell me not to
top-post and to use a correct sig delimiter... :-) There are actually 2
communication problems about this stuff in usenet:
1. People who tell newbies they are assholes instead of just pointing
them the right direction
2. Newbies who assume they are told to be assholes even if they are
politely pointed to the right direction...

It's one of those things I can't figure out. Even without the aspects of
vanity, selfishness or rudeness, it is allways tempting to consider ones
own views and ideals as ultimately correct, which I straight off would
think made it very doubtful, that a person would change his ways merely
presented with a polite suggestion. (both ways)

It would have been easy, if the "rules" had been all facts and numbers, but
they aren't. People come in from a world of liberal thinking, individualism
and cut-throat competition. Much different than the ideas of uniformity and
altruism on the net. It is two worlds with widely different definitions of
"common sense" and efficiency.

If people don't readily believe it (whatever "we" make up), then without the
means of persuasion by appeal to facts or common sense, what else is there
than to just generally make it unpleasant to disagree, and in return expect
any reasonable person to object to that.

Then again, who would deny sinners a fair chance to repent. :)

I had the same problem. Page 1 uses an image map (the layout of booths
at a festival). Depending on where you click it calls page 2, sending it
the booth number you selected popping up a new window with the booth
number preselected. (ooooooooo)

<.in.Javascript...>(page booth1.php)
url = "booth2.php?" + "booth=" + booth;
win4 = window.open (url ,"", option);

:-O Notice :-O Notice ... Notice
(oh shutup)
So I added the ?missing? items.
url = "booth2.php?" + "booth=" + booth +
"&name=&address=&phone=&email=&comment=";
win4 = window.open (url ,"", option);

The silence is deafening :-D

As an aside - Why da flip did someone decide that the "Notice" needed to
be spit out is beyond me. And shouldn't (is) there be a way to say
"Shhhhhhhh" IE "<?php -quite"

This is actually a service for you. Imagine writing an application with
some 1000s of lines of code, and at the end you just get a blank page -
I bet you would be quick in blaming PHP for letting you stand in the rain.
And shouldn't (is) there be a way to say "Shhhhhhhh" IE "<?php -quite"

If parameters are are optional it is quite easy to code:
$thing = isset($_POST['anything']) ? $_POST['anything'] : false;

If you prefer it the dirty way you can disable any level of error
reporting: www.php.net/error_reporting.

Good luck

Should actually display 3 undefined constant notices... change the use
of quotes, quote strings but not variables:

$list = array ('name', 'address', 'phone');
foreach ($list as $item) {
