Hi Ephraim,
The problem arises because you're login request goes like this
Link on page => Auth#Facebook controller action => in browser redirect page =>
Facebook (here be dragons) => Auth#facebook_callback (or something) You loose
the param either during the redirect or in the dark heart of Facebook.
Things to try:
1) Check request.env["omniauth.params"] in the return action. Your original
param might be hiding there.
2) Save the value to a cookie and then retrieve it when you come back
Also you've got an extra "?" in your example code
<%= link_to image_tag("FB_logo2.png"), "/auth/facebook?param1=#{temp_user_id}?"
%>
should be
<%= link_to image_tag("FB_logo2.png"), "/auth/facebook?param1=#{temp_user_id}"
%>

I my application, I have users enter some information, and only then do I allow
them to register. I want to give them the option of either registering directly
or conveniently with Facebook. I use Omniauth (I don't use Devise). I save the
information they already have entered, and then I want to augment it with other
stuff after they sign in. I give them a temporary id (random number), which I
want to pass to Omniauth so that when they finish registering with Facebook, I
can find their temporary record and do with it what I want.
Basically, I want to use something like this in my view:
<%= link_to image_tag("FB_logo2.png"),
"/auth/facebook?param1=#{temp_user_id}?" %>
The generated url then is this (I am in development in my local machine)-
localhost:3000/auth/facebook?param1=3458768267844234
When I click the link, this is what happens (from my debugger)-
Processing by OmniauthsController#create as HTML

I get all the usual Omniauth parameters that I would have gotten without the
added param1, but param1 is not passed along.
Thank you for any help here.
Ephraim
