[Chameleon] Beginner needs help.

Hi Kevin,

Not sure about the legend problem, but as far as I know, php_mapscript is not expected to run well as a module. You also have to make sure you use the correct version of php. I think mapscript 4.6 was compiled against php 4.3.11, so best make sure that that is what you have.

The log messages you have, are they from your php log, or your webserver log?

regards,

Jacob

Hi all.

I'm a complete javascript/DHTML rookie but after seeing the fantastic
interfaces developed using Chameleon at OSG'05, I thought it would be
worth the big dive.

I have successfully installed Chameleon 2.2 and have made the samples
work.  My goal was to have a fixed base map containing colored area map
and some feature data such as state boundaries, major roads & rivers
etc, then allow the user to overlay different wms based layers.

I started with sample_enhanced and changed it to use the JSAPI.  I then
added a simple button did this:

goCWCJSAPI.oMap.AddWMSLayer( "Overlay", "Sample Overlay", "epsg:4326",
"http://localhost/maps/cgi-bin/mywms.py", "1.1.1", "gif");

There are two problems now:

First, the Legend is refreshed but it has double entries for all the
layers in the base map file.

Second, I'm getting intermitent core dumps.  I was running php 4.3 as an
apache module and using php_mapscript 4.6.  I have changed to using php
as a cgi using the little helper script to set the proper environment
var.  But this only changed the log messages from "unexpected end" to
"php segfault".

What is the proper way to add a layer to a map dynamically?  Any help
with the seg fault would also be appreciated.

Thanks
