[Phpwiki-talk] Questions about phpwiki 1.3.4

[Alexander D. <me...@ea...>]

I have installed phpwiki and am using it with mySQL.  I am hosting the 
site on my own computer.  Part of it runs just fine, but I have two 
questions.

First, when I access the phpwiki site locally, there is no problem.  
When I access the site remotely from the internet there is a problem.  
The links created using [ and ] point to 
"http://mycomputername.local/phpwiki/index.php/thenameofthewikipage".  
As I said, this works on my local network, but obviously not from the 
web.  If I manually type in 
"http://myipaddress/phpwiki/index.php/thenameofthewikipage" the page 
does come up fine.  Is there a way to change the "mycomputername.local" 
in the index.php so that it just points to the local server instead of 
the name my computer has in the local network?  What part of index.php 
do I need to change, and how do I need to change it?

My second questions is, where are the new pages being created?  In the 
"INSTALL" file it says that new pages are created in a "tmp" folder.  I 
do not have a "tmp" folder in my phpwiki folder.  So where are these 
pages being created?

The first question is more practical and the second question is more 
academic.  Thank you for any help you can offer me.

It's really a problem with your http server configuration.
By default, PhpWiki deduces the server host name from the $SERVER_NAME
environment variable which is set by the http server (e.g. apache).
So the best way to fix the problem is to fix your web server configuration
so that it reports the correct server name.

As a work-around you can manually set SERVER_NAME in index.php.
Uncomment the line which says:

  if (!defined('SERVER_NAME')) define('SERVER_NAME', 'some.host.com');

and change 'some.host.com' to something more appropriate.

The pages are stored in the MySQL database (if you're using the MySQL
backend, which you are.)

Yes, but your server really ought to be able to tell it's CGI programs
how to form a complete URL to themselves.  If you're using apache
this should be possible, though I'm unsure of the details.  Probably
it involves setting up multiple virtual hosts with (slightly) different
configuration, depending on what ethernet interface the request is
coming from.

Another common solution to your problem, is to use separate internal
and external DNS nameservers, so you can have the same host name resolve
to different IP numbers depending on whether you're on your internal
network or the external internet.  (Since it's the same machine,
it should have the same name.)

Yes.  That's a fine solution.  Getting PhpWiki to do that would take
a bit of work, but you could try.  (It may be as simple as editing
lib/config.php so that SERVER_URL gets defined to the empty string.
You could try that --- I'm not sure it will work, and it probably
will break something (e.g. RSS RecentChanges).)


As a hack, you could try setting SERVER_NAME from $_SERVER['HTTP_HOST']
(in index.php, that is).
That picks up the host name from the Host: HTTP header sent by most
modern browsers.  (The Host: header is required by HTTP/1.1.)  It may
not work with a few rather old browsers.

Something like:

if (isset($_SERVER['HTTP_HOST']))
    define('SERVER_NAME', $_SERVER['HTTP_HOST']);
else
    define('SERVER_NAME', 'pick.one.com'); // punt and hope you guess
right.
