external hotspot login problem

Hi all.
I have realized an external hotspot login page.

I cannot understand what I must do when an user click login from my external login page:

  • I need to login in the hotspot
  • i nedd to pass to the hotspot user and password and redirect page

Must I use a post call to a login page ?

thanks
