I'm having problems getting the form parameters in the following Compojure example:
(ns hello-world
(:use compojure.core, ring.adapter.jetty)
(:require [compojure.route :as route]))
(defn view-form []
(str "<html><head></head><body>"
"<form method=\"post\">"
"Title <input type=\"text\" name=\"title\"/>"
"<input type=\"submit\"/>"
"</form></body></html>"))
(defroutes main-routes
(GET "/" [] "Hello World")
(GET "/new" [] (view-form))
(POST "/new" {params :params} (prn "params:" params))
(route/not-found "Not Found"))
(run-jetty main-routes {:port 8088})
When submitting the form the output is always
params: {}
and I can't figure out why the title parameter is not in the params map.
I'm using Compojure 0.6.2.

Have you taken into account this:
As of version 0.6.0, Compojure no longer adds default middleware to routes. This means you must explicitly add the wrap-params and wrap-cookies middleware to your routes.

I tried your example with my current setup and it worked. I have included the following: require [compojure.handler :as handler] and (handler/api routes).

This is a great example of how to handle parameters
(ns example2
(:use [ring.adapter.jetty :only [run-jetty]]
[compojure.core :only [defroutes GET POST]]
[ring.middleware.params :only [wrap-params]]))
(defroutes routes
(POST "/" [name] (str "Thanks " name))
(GET "/" [] "<form method='post' action='/'> What's your name? <input type='text' name='name' /><input type='submit' /></form>"))
(def app (wrap-params routes))
(run-jetty app {:port 8080})
