Hi:

Is there a way to set a session variable in a check box that’s not in a  
form nor linked to a controller? The checkbox value would also be the  
value of the session variable I want it to set. I assume I have to put  
this in a form. Any suggestions?

Thanks very much in advance!

Mike

just an idea, but you could do an ajax call on an onchange event of the  
checking-of-the-box:

create the function

and then just do an action in the ExampleController

def set  
session[:checkbox] = params[:session\_setter]  
render :nothing =\> true  
end

all untested code…might need to modify the ajax statement above to  
pass the param[:session\_setter] in “parameters:…” but an idea, no?
