UPDATE 15. april 2010 NEW VERSION WITH FACTIONPRICES! - http://eve-id.net/forum/viewtopic.php?p=31192#p31192
Hey
Ive put together this little mod, it downloads an xml file from my server.
The xml file contains cached data from the eve-central server.
Client:
3/2 2008: Now php4 and php5! php5 is MUCH faster, so use it if you can! (php5 uses compressed stream).
4/2 2008: Now updates ships too (if you want it).
5/2 2008: Check for latest update

6/2 2008: PHP4 actually works now

8/2 2008: Only sell orders, don't take buy orders into account! Can be changed in fetcher.php.
8/2 2008 - 2: Fixed typo!
13/2 2008: Now using median prices as supplied by friendly poster. It is possible to change around since all data is still in the xml file! Look in fetcher.php for info!
13/2 2008 - 2: New settings page, better looking, better working, simply better

13/2 2008 - 3: Made some small changes to the urls, working better serverside now

17/2 2008 - 1: Added "date" versioning, look at your settings page for your version number!
11/3 2008 - 1: Made the faction pricesavailable via feed! Please give feedback! Only use on test killboards for now! Disabled by default! Cronscript also included!
12/3 2008 - 1: New version, now actually works


3/4 2008 - 1: Fixed faction prices in php4 version.
5/4 2008 - 1: Fixed the problem with wrong prices from large numbers!
----
22/9 2009 -1: Updated to use new price file. You can also specify an alternative path or you can enter a local filename (untested).
Server:
21/7 2008 -1: Changed prices to be only The Forge.
28/7 2008 -1: Removed BellaTroix median price. Using eve-central instead.
---
22/9 2009 -1: Updated to use another pricelist.
Try it out:
http://assets.evsco.net/files/value_fetch.tar.gz
Place it it the mods directory, enable and click settings!
I use this in my cron:
15 14 * * * /usr/bin/php /var/www/killboard/mods/value_fetch/cron.php >> /dev/null 2>&1
Remember to edit and test it first (php cron.php).
Following is not used anymore:
If you find faction prices that are wrong, go --- and input the correct value!
I borrowed some stuff from other mods, especially the value_editor, thanks

Try it out and come with feedback.
