I figured out my problem but I am not sure why this is.
I am trying to implement a back button to allow the user to go back and
change form values.
If I use sessions and register $test then this does not work, the value of
$test does not change if the user re-submits:
<input name="test" type="text" value="<?php echo $test;?>"/>
Thanks for any help!

Actually, it's not the reverse that I want to do.
Right now the pages on my site use this form of URL:
domain.com/articles.php?id=999
Now that I have upgraded my server to Apache 2, I'm going to use the
ForceType and FollowSymLinks options to change the entire site to use this
search-engine-friendly form of URL to access all pages:
domain.com/articles/999
But I don't want the old links to be broken once I change the site to this
new type of URL. So, if someone types in "domain.com/articles.php?id=999",
instead of getting a 404 error, I'd like to use the RewriteEngine to rewrite
that URL to the valid new URL format: domain.com/articles/999.
So, I thought this would work in my .htaccess file, but it doesn't:
RewriteRule articles\.php?id=([0-9]+) articles/$1 [R]
Do I have to escape the ? before id \? I tried it, but it didn't make a
difference. I also tried /articles... but that didn't work, either.

Rather than rewriting URLs like you're attempting, I think you might find
it easier to just use a 404 handler to decide what the best URL is for the
user. This is a good idea in general anyway, since it can help more than
just old URLs, but also typos and the like.
You mention ForceType, so I can assume you're using Apache. Try this in
your httpd.conf or in a .htaccess file:
ErrorDocument 404 /404.php
Then, in /404.php, use $_SERVER['REDIRECT_URL'] to determine where you
should send the user. You can use:
header('Location: http://domain.com/articles/999');
In addition, you can send your own response status code that indicates
that this is a permanent redirect, not a temporary one.
Hope that helps.

Are you sure you have both mod_rewrite and .htaccess installed on the new
apache then? Things like this is often very silly you know, you look past
the problem (I've done that several times)...
RewriteRule "/articles\.php\?id=([0-9]+)$" "/articles/$1"
Although, I've never even used mod_rewrite so I'm not the right person to
ask...
Check the news server news.gmane.org, there you can find most of the Apache
lists..
gmane.comp.apache.user for example... Or on any server, try
alt.apache.configuration, comp.infosystems.www.servers.****
You'll most likely get alot more help there, since those are pointed towards
apache rather than PHP...

I wrote my own template system that works very well... I've got an outer
control file that handles the user input, sets the variables for what the
template should use of stylesheets and menus and such, and a variable for
what body to use. All my body files are either PHP programs in themselves
mixed with HTML presentation (I try to keep near all the PHP in the start,
and the actual presentation generation at the end).
Basically it means that the template only holds the basic table structure of
the site, and a little code to include the files that are needed to make it
into what it's suppose to look like.
The way I made it I can use the same template file all over the site, or
make another template and tell the control scripts to use that instead. I
still haven't made it possible for the menu system to change looks though,
but I plan to add that in the future...
It would be very easy to change my system to allow it to use different
templates or other elements based on various conditions....
FWIW

My opinon on that is that template system role is to separate presentation
logic from the html which can be considered as resource. Therefore I do not
prefer template systems with embeded control structures in it. But I guess
it is a matter of ones own preferences, and what is "right approach" for
them it is not necessary right for me and other way around.
I completely agree that it is also necessary to separate bussines logic from
the presentation, but I do not think this is a job of template system.

Thanks for any help. Even if I remove the specific default value for the
text input, only the first posted value seems to be accepted and stays
regardless of whether I change it :(
test10.php
-----------
<?php session_register("test");?>
<body>
<a href="test11.php">NEXT</a>
</body>
test11.php
-----------
<?php session_start();?>
<body>
<form name="form1" id="form1" method="post" action="test12.php">
<input name="test" type="text" value="<?php echo $test;?>"/>
<input type="submit" name="Submit" value="Submit" />
</form>
test12.php
-----------
<?php session_start();?>
<body>
<?php echo "HELLO: ".$test ; ?>
<p><a href="test11.php">START OVER</a> </p>

You have started a new thread by taking an existing message and replying to
it while merely changing the Subject: line.
That is bad, because it breaks threading. Whenever you reply to a message,
your mail client generates a "References:" header that tells all recipients
to which posting(s) your posting refers. A mail client uses this information
to build a "thread tree" of the postings so that it is easy to see just how
they relate to each other.
With your posting style you successfully torpedoed this useful feature; your
posting shows up within an existing thread even though it is completely
unrelated.
Always do a fresh post when you want to start a new thread. That means that
you do not select any sort of "Reply" when you start your message. You can
save the list address in your address book (or equivalent) for convenience.

% Hi,
Hi!
%
% I was wondering if there is an easy way to port perl scripts to php, or
% maybe someone could recommend someone who could help me?
The two languages are not terribly different; you may be able to do the
porting on your own if you know php.
You could exec the perl script and get the result if that setup works for
you.
I would be happy to be of service if you would like. Feel free to drop
me a reply.

A database server by nature must assume that all data is equally mutable.
An application developer, however, knows by design how "fresh" any one
piece of data needs to be and can cache accordingly. E.g., don't hit the
database for your site's navigational structure or news articles every
single time, if these things don't change more than a few times per week.
I have found SQL_CACHE to work ok ?

check "pete M"'s mail in this list, sent at 25 NOV 2003.
As written in that mail
<quote>
Another idea would ne to use an "application" variable..
This is like a Session variable but is site wide

i want to convert case of cyrillic characters in the utf-8 string
