I am wanting to add some cave databases to the web along the lines of what Andrew describes here http://therion.speleo.sk/wiki/doku.php/contrib:databasequery
 
I have something working locally based on what Andrew submitted, although their are minor warnings that my system throws up, presumambly due to different system requirements, that I think I can fix.
Before I teach myself php, I thought I should ask to see if anyone has developed Andrews code, or something similar, to a more comprehensive extent, and if they have ask if they would share it?
 
Ideas I have are;
-more comprehensive result tables
-add map awareness, ie debug which surveys have no scraps or no maps of particular projections
-debug which surveys have no surveyors or no explorers
etc
 
Thanks
Bruce
