If your form's method is "post" then reference the quantity value with $_POST['quantity']; if your form's method is "get", use $_GET['quantity']. You sound very new to this, and the fact that you're building a shopping cart is worrisome...so please read up on the importance of verifying your form data, i.e. always "sanitize" submitted values before using them in SQL calls. And simply check that the values you get are what you expect, i.e. if you're expecting a number in $_POST['quantity'], make sure it's a number... By the way, values submitted in a form will be strings, so in the example above you'd actually be checking for the *existence of numbers only* in the string. Good luck.

RE: [PHP] undefined variable
You seem confused with POST & GET, instead of using _POST to retrieve
values from the form, you use $senders_name, and further down you set
$_POST["msg"], which will only be used in the same php code on the same
page
Try
$msg = "Sender's Full Name:\t" . $_POST['sender_name'] . "\n";
$msg .="Sender's E-mail:\t" . $_POST['sender_email'] . "\n";
$msg .="Did you like the site?\t" . $_POST['like_site'] . "\n";
$msg .="Additional Message:\t" . $_POST['message'] . "\n\n";
$mailheaders = "From: yoyo.monash.edu.my\~nthonyak\M\n";
$mailheaders .="Reply-To: " . $_POST['sender_email'] . "\n\n";

Re: [PHP] Undefined variable problem
Hello
This is the code:
$m = 1;
while ($line = mysql_fetch_assoc($rs)) { //dumping into an array
foreach ($line as $field => $value) {
$tmp = $field.$m;
$$tmp.= $value; /* This is the error line 117*** */
}
$m++;
}
This is basically so that i can use the array via variables like so:
if($tcl2==1){echo $tcl2;}
instead of: if($arrayname['tcl']['1']==1){echo $arrayname['tcl']['1'];} and
so onesp since i have 38 fields.
I can of course just shut off error reporting...but thats not the best
solution right? and i still wouldnt know whats causing these notices...
Simply define $$tmp -variable before adding stuff in it.
[code]
$m = 1;
while ($line = mysql_fetch_assoc($rs)) { //dumping into an array
foreach ($line as $field => $value) {
$tmp = $field.$m;
$$tmp = "";
$$tmp .= $value;
}
$m++;
}
[/code]
No it should whine about undefined vars.

Thanks! The only way to do that is to reduce the error reporting level to not include E_NOTICE. Ideally, you should run a development server which has error reporting set to E_ALL, and only copy scripts to your production server once they produce no messages at this level -- your production server can then run with a reduced error reporting level (even down to none at all, if you feel confident about that ;). Ideally, if your production server does run with no error reporting, you should have error logging enabled as a safety net! Cheers!

A better idea is to crank up error reporting all the way on your dev box, write your code so that it doesn't generate any NOTICES etc, and then turn off display_errors on the production box. It's a good idea to log the errors or write a handler or something for when errors aren't being displayed. -- Torben Wilson <[EMAIL PROTECTED]>+1.604.709.0506 http://www.thebuttlesschaps.com http://www.inflatableeye.com http://www.hybrid17.com http://www.themainonmain.com - Boycott Starbucks! http://www.haidabuckscafe.com - -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Check and initialize your input variables:
if (!isset($_GET['action'])) {
$action = '';
} else {
$action = $_GET['action'];
}
switch ($action) {
case 'something':
do_something();
break;
case 'something_else':
do_something_else();
break;
default:
echo "Unrecognized action given";
break;
}
If this is something you need to do for every page on your site, put
the if() check into an auto-prepended file or something.
Hope this helps,

Re: [PHP] Undefined Variable
Hey Anthony--
It's definitely a register_globals problem. Your ISP has turned it off
because it's generally considered a significant security risk.
The best way to solve it is to use the superglobal $_POST to access your
post data. In your PHP script, change all the variables that you take
from the form into their $_POST[''] equivalent (see below for a rough
example--I put the assignments at the beginning because I wanted to
touch your code as little as possible). Also, keep in mind that you're
not performing any checks on the data--I'm sure you want to do it once
you've sorted the current problem out, but the way it is now you're
leaving yourself exposed to a number of possible attacks.
$thename = $_POST['thename'];
$email = $_POST['email'];
$description = $_POST['description'];
$bizname = $_POST['bizname'];
$contactname = $_POST['contactname'];
$phone = $_POST['phone'];
$email = $_POST['email'];
$mailing = $_POST['mailing'];
$town = $_POST['town'];
$state = $_POST['state'];
$zip = $_POST['zip'];
$cat = $_POST['cat'];

How does that "not work?" It should, as long as you're including the
line before the others that are giving you the notice.
You can also turn down your error_reporting setting in php.ini. You can
turn off notices and just see warnings. There is an example within
php.ini.

Its off by default in newer versions (see the README with your source). Either turn it on or better, use $var = $_GET['varname'] for GET variables and $var = $_POST['varname'] for POSTED variables. The "undefined" means that you are using a variable before giving it a value. Probably caused by the above, but you may also have errors set at E_ALL.

Good day.
What is this message that you get, that you don't want?
A cursory glance of the code reveals two "else" statements attached to the
same "if" statement. You should address that.

Re: [PHP] Undefined Variable in formular... what happens???
Most likely it has to do with your error_reporting setting. See :
http://uk.php.net/manual/en/phpdevel-errors.php#internal.e-notice
http://uk.php.net/manual/en/features.error-handling.php
Level E_NOTICE produces Warnings such as "Undefined Variable", so, doing
the following :
echo $iamnotset;
Produces such a Error/Warning. Any "direct" use of $iamnotset will, which
is why functions such as isset() and empty() exist :
if (isset($var)) echo $var;
I am guessing either you have :
if ($submit) {
// process form and no Warnings as $submit is set
} else {
// show form and WILL show the Warnings as $submit is not set
}
Consider :
if (isset($submit)) {
It's not uncommon to have E_NOTICE off but good little PHP developers
develop with error_reporting turned up full blast, E_ALL in da house!
Second, perhaps you expect register_globals to be on, see the following :
http://uk.php.net/manual/en/configuration.php#ini.register-globals
http://uk.php.net/manual/en/security.registerglobals.php
If off, foo.php?fruit=apple will not create $fruit but rather, you'd go
through a predefined variable like : $HTTP_GET_VARS['fruit'].

Re: [PHP] 'Undefined Variable' help...
Hi Uchendu!
Yes, this is very possible! Here are a few things that come to mind.
There are of course many ways to do this :
To check the existance of a variable, consider isset() as it checks for
the existance of a variable :
if (isset($HTTP_GET_VARS['images']))
Maybe set some default values for unset variables :
if (!isset($width)) $width = 300;
if (!isset($breads)) {
$breads = array('rye','wheat','raison');
}
A little debugging :
A "Undefined Variable" Error is level E_NOTICE. More error handling
information can be found here :
http://www.php.net/manual/en/features.error-handling.php
Doing the following will create a "Undefined Variable" Warning such as :
if ($submit) // if (isset($submit))
echo $iamnotset; // if (isset($iamnotset)) echo $iamnotset;
Warning: Undefined variable: submit in /home/http/file.php on line 24
Warning: Undefined variable: iamnotset in /home/http/file.php on line 25

There will probably be different levels of error reporting in the two
php.ini files.
view is an index of the array $HTTP_GET_VARS, and is apparently not
defined at that part of the script.

Is the variable a user defined variable? If so, my guess is the error reporting level for the two servers is different. See the error handling section of php.ini and see if the default settings differ b/w the two servers. Also see error_reporting() if you're explicitly using that function. If the variable is a PHP or environment variable perhaps the variable is available on Apache, but not on Win2k. I have very little experience with PHP on Windows so it could be something else, but that's where I'd start. -- Steve Werby COO 24-7 Computer Services, LLC Tel: 804.817.2470 http://www.247computing.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
