I have a small script that works fine on the development server,
but when I try to run it for real on the production server it
does not work.
here is the html:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>CaseNoteCheck</title>
</head>
<body>
<h2>Case Note Edit Checker</h2>
<form action="caseNoteChecker.php" method="POST"
enctype="multipart/form-data" >
<input type="hidden" name="MAX_FILE_SIZE" value="40000" />
<input type="file" name="caseNote"/>
<input type="submit"/>
</form>
</body>
</html>
here is the top of the php script:
<?php
//caseNoteChecker.php receives file from CaseNoteChecker.html
session_start ();
error_reporting(E_ALL);
$_SESSION ['current_user'] = "WPD";
echo "<pre>";
print_r($_POST);
print_r($_FILES);
echo "</pre>";
On the development server the file uploads correctly and all is
well. On the production server the $_FILE array is empty.
Array
(
[caseNote] => WPD-CaseNotes.txt
)
Array
(
)
and naturally it fails.
I searched with google and found a terrific article by jkorpela,
but afak I am doing it right.
Suggestions to debug this please. It must be a server
configuration issue but I don't know where to look.

The fact the $_POST array is empty means PHP isn't getting the
information from the web server.
First thing to check on things like this is your HTML - is it valid?
Next would be differences between the two web servers.

Sorry - sent before I meant to
If all these fail, the next thing to check would be differences in PHP
version on the two systems. I haven't seen any problem with $_POST in
PHP, but that doesn't mean it doesn't exist.
The other thing you might want to do is add display_errors=on to your
script. But your problem here is the $_POST initialization is long
before you get to any code in your script, so if there is an error in
setting up $_POST, you'll never see it. In such cases it's better to
place the values in your httpd.conf file (if you're using Apache). See
http://www.php.net/manual/en/configuration.changes.php for more
information on how to do this.
NOW I think I'm done :)

"Well it looked valid"
However the W3C validator wanted the form contents in a <div> so
I did that and now it works.
Thanks Jerry
Another question: I write a lot of program fragments that are
loaded via AJAX into a huge application. I obviously can't
validate them by submitting them to the W3C markup validation
service, does anyone have suggestions on how to validate the
fragments ?

Try an HTML newsgroup.

Write it properly in the first place. Generating valid markup is not
*that* difficult. Validating a fragment is futile anyway, since it lacks
information about document type, encoding, surrounding markup etc.
Besides, I suppose you are injecting your XHR delivered markup by
setting the innerHTML property, which is proprietary and on some
browsers laden with problems.
Both topics are better discussed in c.i.w.a.html and c.l.javascript
respectively.

Are the server PHP versions the same? Deprecated or "improved" features can
cause a lot of problems.

Yes they are. Still no clue why "identical" servers would behave
differently, but cleaning up the html (thanks Jerry) fixed that
problem.
