[dancer-users] passing a variable to a new subroutine route

[Richard Reina]

Hi WK,

Thanks again for the reply.  When I try it your way:

redirect "/sport_add/$id";

Dancer attempts to serve up the page /sport_add/105 (105 being an the value
of $ID) and of course gets an error. Not sure what I am doing wrong. Also,
are you saying that hook before makes the var S_id global? I have tried
invoking it briefly in other routes and it did not seem to be in scope.

Thanks for the help.
