Hi there again everybody, I listened to the advice previously given, adn
have now got chameleon 1.1, and the sample application. However,
getting them to work in the context I am after is proving beyond me.
My sample app is in:
/var/www/html/test/
That would be everything, and I have my apache server setup to use this
as the document root:
http://test.mydomain.com -> /var/www/html/test/htdocs/
OK, now the chameleon files have been arrange like this:
/var/www/html/chameleon/htdocs/
/var/www/html/chameleon/config/
/var/www/html/chameleon/htdocs_admin/
/var/www/html/chameleon/html/
/opt/data/
/opt/etc/
The apache web server has been setup to use this as the document root:
http://chameleon.mydomain.com -> /var/www/html/chameleon/htdocs/
I have the following as a tmp directory:
/var/tmp/
OK, and in the sample app I changed line 9 to be:
include( "/var/www/html/chameleon/htdocs/chameleon.php" );
and the map file to be:
$szMapFile = "/var/www/html/test/map/chameleon.map";
--------
Right, so now that leaves me with one problem...how do I configure the
xml file to portray this. Here's what I've got, and I get errors saying
it couldn't find my mapscript php extension (Which I definately have the
right name for).
