[ka-Map-users] RE: Multiple URLs - one ka-map install - variablepassing question?

[Steve Walker]

I have partially solved my own question posted below.

I have discovered the following:

To view multiple pages such as
http://www.blahblah.com/location1 and
http://www.blahblah.com/location2

from the same ka-map back-end, do the following:

Modify the init.php, changing file 'includes' as necessary to point to the
correct locations on the file system (ie tile.php, config.php) as you will
copy the init.php file to multiple locations on the file system and the
relative pointers to these files may/will break.

Also in init.php, insert the line
include_once('./variables.php');
before the include_once( 'config.php) entry.  This pulls in the variables
(extent, map name, title) as noted in my original posting.

modify the *.js files again to replace path names as necessary, for the
same reason as above (ie from 'images/blahblah.jpg' to
'/ka-map/images/blahblah.jpg'

copy both the init.php files to the corresponding location(s) on the file
system.

re-write the index.html files (using scripts & templates) to reflect the
page-specific values from variables.php such as name, title, etc.

/var/www/htdocs/location1/init.php
/var/www/htdocs/location1/index.html
/var/www/htdocs/location1/variables.php

/var/www/htdocs/location2/init.php
/var/www/htdocs/location2/index.html
/var/www/htdocs/location2/variables.php

This solution works as you can see for example from

www.usmapserver.com/Washington
www.usmapserver.com/California
www.usmapserver.com/California/Los_Angeles

However, drawbacks include:

1.  need to make a copy of init.php for each desired web page rather than
pointing to a single master.
2.  need to (progromatically) re-write each index.html (ie to generate
title, name, links) from scratch rather than including these values at
run-time.

I am still scratching at the surface of understanding and will report
anything else I learn.
