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. 2015-08-24 11:45 GMT-05:00 WK <wanradt@gmail.com>:

Thank you very much for the reply. Before I saw this came up with this solution to pass the variable to the other sub/template:
# take them to the add_sport (but with the id no) hook 'before' => sub { var S_id => $select_id; request->path('/sport_add') };
redirect '/sport_add';
You may need before-hook sometimes, but not now (if I understood you correctly). before-hook is executed on every request. Mostly you don't have need to set id such way for every route. For basic data submitting is best to submit data to post-route and after successful data-saving redirect to result page. Like this:
post '/sport_add' => sub { my $id = params->{ id }; # DO something to store needed data redirect "/sport_add/$id"; };
get '/sport_add/:id' => sub { my ( $id ) = params->{ id }; template 'sport_add', { id => $id }; };
It actually worked but I was wondering if doing it this way with hook and redirect is a bad idea?
The before-hook was redundant there, redirect was right way.
In cookbook is shown one way to use it:

Also, I was wondering why it's a bad idea to print input from dancer to the console? Does it produce a security vulnerability or is it merely disruptive to dancer?
Have you tried to print there? You print into SТDOUT and you ruin http-headers, resulting faulty page. print does not send anything to console, use log-methods for it (like debug).
Wbr, -- Kõike hääd,
