Still trying to wring knowledge from the documentation on HTML Legends
but with this one I need some help.
I've got a mapfile that has a normal set of layers with no groups, and
then I 'INCLUDE' two additional mapfile fragments which are grouped
roads and grouped hydrology (rivers, lakes, various and diverse
wetlands, etc.) When I use the following code in my html file, I see all
the layers represented in the mapfile:
[leg_layer_html order_metadata=legend_order opt_flag=15]
<input type="checkbox" name=layer value=[leg_layer_name]
[if name=layer_status value=1]CHECKED[/if]>
[if name=layer_type value=4]
<img src=[leg_icon width=22 height=18]>
[/if]
[if name=layer_type oper=neq value=4]<img src=[leg_icon]>[/if]
<a href="[leg_layer_name]">[metadata name=WMS_TITLE]</a><br />
[/leg_layer_html]
The titles are hypertext links but they go nowhere; I'm just blindly
copying what's in the docs, but I think this is just an extra freebie
example within an example, so ignore it for now. Anyway, this code works
as expected.
The problem occurs when I put a group header in front of this,
specifically this bit of code:
[leg_group_html]
[leg_group_name]<br />
[/leg_group_html]
With this added in I'm getting ONLY the road legend (which is displayed
on top); the hydrology and the other layers are nowhere to be seen (I
also checked with firefox to see if they were even there, perhaps lying
hidden, but of them I could find no sign.)
Does this group configuration only work one one group at a time? How do
I see all groups and non-grouped items? Can I selectively show all group
names but hide the details like a expandable tree control? In short,
where are the solid barriers to using this method to provide an
unlimited layer and legend control? Or have I already hit it's
limitations? Help with any or all of these questions would be very welcome.
Or if someone could just point me to a /working/ example of a fully
tricked out HTML legend, that would be ideal. The one listed in the
documentation,
http://www2.dmsolutions.ca/msapps/itasca_legend/demo_init.html, is
unhelpfully still broken.
...and if it matters in this case, here's my mapserv version info:
$ /var/www/cgi-bin/mapserv -v
MapServer version 5.0.3 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP

Thanks for your help,
