Question

Error testing locally; works fine on remote server

I was about to post that I'd hit an error when trying to create a
conditional region in DW 8 with ASP, CF & PHP: Training from the Source.
Rather than paste the non-PHP code, I uploaded the page to my remote server.
When I browsed to the link, the error wasn't there.

I inserted the code for the conditional region just before the opening
<form> tag, as the book instructed (Lesson 6).

<?
if ($_GET['error'] == "notnumeric")
{
echo "<p>*** Error! One or more fields was left blank or contained a
non-numeric character.</p>";
}
?>

When I preview locally, the page appears correctly, but with the following
message before the form:

Notice: Undefined index: error in C:\Program Files\Apache
Group\Apache2\htdocs\newland\Lesson06\Start\newland-php\tourprice.php on
line 27

Line 27 is where the "if" statement starts.

On my remote server, everything works as it should:

http://www.feathertheweb.com/newland/Lesson06/Start/newland-php/tourprice.php

Any help is appreciated.

Thanks,

Heather

Whoops.

All fixed and working now. :-) Thanks again!

That's where PHP Notices are very useful. It tells you that nmChildren
is undefined. Look at your code again:

> is_numeric($_POST['nmChildren']) == false)

> $numChild = $_POST['numChildren'];

The first one is $_POST['nmChildren']; the second is
$_POST['numChildren']. You have misspelled the first one.

The headers already sent error is caused by the display of the Notice.
Once you have corrected the spelling, it should go away.

So, I changed the code you had provided and that worked. Now, I've tested
the form and when I click "submit," I get this:

Notice: Undefined index: nmChildren in C:\Program Files\Apache
Group\Apache2\htdocs\newland\Lesson06\Start\newland-php\tourprice_processor.php
on line 2

Warning: Cannot modify header information - headers already sent by (output
started at C:\Program Files\Apache
Group\Apache2\htdocs\newland\Lesson06\Start\newland-php\tourprice_processor.php:2)
in C:\Program Files\Apache
Group\Apache2\htdocs\newland\Lesson06\Start\newland-php\tourprice_processor.php
on line 4

I'm guessing it's related to the change I made in tourprice.php. I tried to
figure out what needed to be changed in tourprice_processor.php based on
that change, but I'm still pretty new at this and really wasn't sure.

Below is the code from tourprice_processor.php:

<?php
if (is_numeric($_POST['numAdults']) == false or
is_numeric($_POST['nmChildren']) == false)
{
header("Location: tourprice.php?error=notnumeric");
exit;
}
?>

<?php
$numAdult = $_POST['numAdults'];
$numChild = $_POST['numChildren'];
$basePrice = $_POST['tourName'];
$tourPrice = ($numAdult * $basePrice) + ($numChild * $basePrice);
?>

It's badly written code. It should be

if (isset($_GET['error']) && $_GET['error'] == "notnumeric")

> On my remote server, everything works as it should:

That's because your remote server has been configured to suppress PHP
notices.

PHP notices alert you to non-fatal mistakes in coding. A lot of people
just ignore them, but it's a sloppy habit to get into, because it can
lay your scripts open to attack. Before testing the value of a variable,
you should always use isset() to check that the variable has been
defined in the first place.
