Question

I’m new in play framework and I’m trying to do a simple post to server.
In my routes I set:

POST    /Hello/add          controllers.Hello.add(name)

In my Hello.java class I set:

public class Hello extends Controller {
    public static Result add(String name){
        //add code
    }
}

And in my html file:

<form action="Hello/add" method="post">
    <input type="text" name="name" />
    <input type="submit" value="Add" />
</form>

But when I click on the button ‘Add’, is lauched the following exception:

For request 'POST /Hello/add' [Missing parameter: name]

Someone knows why?

You have to use a DynamicForm in your Action, and to do not specify any parameter in the route file:

The route:

POST    /Hello/add          controllers.Hello.add()

The controller and action:

public class Hello extends Controller {
    public static Result add(){
        DynamicForm requestData = form().bindFromRequest();
        String name = requestData.get("name");
        // do what you want with the name variable
    }
}
