[Chameleon] Querying a dynamic layer

[Paul Spencer]

Ken,

if you want to see the map file that chameleon is currently using, you 
will need to grab the session id by viewing the source of your page and 
searching for an <input> with name "sid", there should be a number like 
"4152fd8f5f9bf" there.  Chameleon uses this to create a directory called 
sess_<sid> in the session save path (configured in php.ini).  For ms4w 
users, this is /ms4w/tmp/

In the session directory you will find a session file and one or more 
map files.  Open the most recent map file to see what chameleon used on 
the last page load.

You can also see all the variables chameleon holds in the session by 
opening the session file or by including the following at the end of 
your phtml file:

echo "<pre>";
print_r($_SESSION);
echo "</pre>";

be warned that there is a lot in here because of circular references in 
some of the php arrays ...

Cheers,

Paul
