Question

this may be RTFM, but i am having difficulty understanding how to access values of input forms variables as TWiki / TopicVars variables. i have read the TWikiDocumentation to no avail.

i am trying to understand how to write code (i guess, a plugin) that would take the value of a checkbox that might be rendered as a form in twiki page, and then assign the value to a TWikiVariable or to a TopicVarsPlugin variable, so that it the the variable could be used conditionally (see ConditionalPlugin).

i'd like to do something similar to the following in a webpage :

      %RADIOBUTTONARRAY{numberofbuttons=3,button_labels="L1,L2,L3",returnselection_variable="SELECTED_BUTTON"}

      %IF{ %SELECTED_BUTTON% eq "L2" }%
      aha, button2 is selected by the user
      %ENDIF%

      %IF{ %SELECTED_BUTTON% eq "L3" }%
      aha, button3 is selected by the user
      %ENDIF%

the RADIOBUTTONARRAY plugin would render 3 buttons with the appropriate labels, the user action would cause the variable SELECTED_BUTTON to have the selected value, which in turn could be used as a conditional variable (ConditionalPlugin) in the text.

(of course also, it would be very nice to have a nested if/else/endif, a C style case statement, and compound conditions for doing this kind of conditional text.)

any suggestions and pointers to appropriate code segments is welcome!
