Need some help with basic form submissions

GET /users/new HelloWeb.UserController :new
…
POST /users HelloWeb.UserController :create
…
source: Routing — Phoenix v1.8.8

The :new route is to get the blank form, hence the GET HTTP request. While the :create route is to submit/post the completed form, hence the POST HTTP request.

If you’re on a relatively new version of Phoenix and ran mix phx.gen.html ..., you’d see a form component with an action that points to a :create route.

<.form :let={f} for={@changeset} action={Routes.comment_path(:create, @comment)}> # or action={~p"/comments"} if using verified routes
  <.input field={f[:body]} />
</.form>

Thann you @codeanpeace for your answer and sorry for the delay,
In fact what I was mistaken about, is that I thinked for a Framework as Regular RESTful API, that means I expected to render a simple html form by calling new and after that sending “manually” the informations to the server and this is not the case for Phoenix.
Iam new to Phoenix and I didn’t use LiveView before, what caught my attention is the link that you gave me which describe the form as “regular http request outside of LiveView” so just if you can tell me or suggest a link of how to do that with LiveView ?

Phoenix supports both traditional stateless RESTful HTTP request/response through Phoenix.Controller as well as stateful WebSocket connections through LiveView Phoenix.Liveview.

If I’m understanding you correctly, you can just scroll up using the link above for an example of using the form component within a LiveView or alternatively use this link. You can also use the mix phx.gen.live task to generate functional LiveView example code.
