[Chameleon] LegendTemplate Widget - Combining checkbox and radiobutton layer selection

[Delfos, Jacob]

Jessica,
 
I think you could get away with modifying the bit around line 539-575 of
LegendTemplate.widget.php, and then making sure that the name of the
inputtype of the radiobuttons in your legendtemplate is set to something
other than "legendgroupname". Alternatively, you could put radiobuttons
in your template, and use "onChange" and some javascript to change the
value of hidden form elements, to turn layers on or off. But that might
be more complicated.
 
regards,
 
Jacob

and radiobutton layer selection
	
	
	Greetings List,
	 
	I am using an instance of LegendTemplate to control layer
selection via a Mapserver HTML template.
	 
	My problem is that I want to combine the use of both checkboxes
(for overlay kinds of layers) and radio buttons (for backgrounds).  I
have metadata in the mapfile that indicates this status. (a snippet of
code from the template is below)
	 
	Unfortunately, because the name element is the same for both
radio and checkbox inputs, a selection of a radio button will turn off
all the checkboxes (problem is limited to Internet Explorer).
	 
	I can't seem to track down where "legendgroupname[]" has roots,
as I initially duplicated the legend widget and tried to rename the
variable in a new widget.
	
	Any advice is much appreciated!
	Best regards,
	Jessica
