Phoenix.HTML.Link.button with params

[LostKobrakai]

Phoenix’s button handling with method is mostly a convenience to not need to wrap just a button with a form, to defines nothing more than a url/method. If you need more data as part of the request use a form with hidden fields. You’re imho past the point there the convenience does make much sense.
For get requests you could alter the url, but a form will also just use get params if you submit it with the GET method. I guess both ways are viable for get parameters.

@augnustin

      content_tag(:form, text, method: method, action: to) do
        if method != :get do
          hidden_field(:csrf_token, Plug.CSRFProtection.get_csrf_token())
        end
        Enum.map(opts[:params], fn k, v -> 
          hidden_field(k, v)
        end) 
        content_tag(:button, text, type: :submit)
      end

And this would work for either :get and :post .

If you’d use form_for instead of content_tag(:form, …) you’d get the csrf token and the method override automatically and it would therefore work for any http method.
