`send_get_form form url result` sends the fields of `form` to `url` through XHR, in the query string, after `~get_args`. With `~post_args`, the request is a POST whose body holds `~post_args`, the fields staying in the query string. `~submitter` is the button that submitted `form`, the `submitter` of its submit event: its name and value are sent, before the fields, as a native submission sends them. An image button sends instead the point of the click in the image, as `name.x` and `name.y`, or `x` and `y` when it has no name. This point is the one recorded by [`track_image_button_clicks`](./#val-track_image_button_clicks) for the last click on this button, (0, 0\) if there is none.

```ocaml
val send_post_form : 
  ?with_credentials:bool ->
  ?expecting_process_page:bool ->
  ?cookies_info:(bool * string list) ->
  ?get_args:(string * string) list ->
  ?post_args:(string * Mod_parameters.param) list ->
  ?progress:(int -> int -> unit) ->
  ?upload_progress:(int -> int -> unit) ->
  ?override_mime_type:string ->
  ?submitter:Js_of_ocaml.Dom_html.element Js_of_ocaml.Js.t ->
  Js_of_ocaml.Dom_html.formElement Js_of_ocaml.Js.t ->
  string ->
  'a result ->
  (string * 'a option) Lwt.t
```
`send_post_form form url result` is like [`send_get_form`](./#val-send_get_form) but sends the fields of `form` in the body of a POST request, before `~post_args`. `~get_args` go in the query string.
