Question

I have a .erb page and when a user is logged in it contains the data like in below code.

<% if logged_in? -%>Welcome, <%= current_user.id %><% end -%>

So what I need is to pass this data to a PHP page using a URL, and it should be done without user interaction(without links,buttons) because the user is already logged in. I know some code like
Link to another site this but I don’t know how to do this in ruby on rails, also this should be automatically submitted to another php page in a different server.

Thanks in advance.

For the sake of demonstration, I’ll assume you’re making a POST request. You can use ruby’s built in Net:HTTP and URI libraries in your controller action method to make such a request:

if logged_in?
  uri = URI.parse('http://remoteurl.com/script.php')
  http = Net::HTTP.new(uri.host, uri.port)
  params = { 'id' => current_user.id }
  request = Net::HTTP::Post.new(uri.request_uri)
  request.set_form_data(params)
  http.request(request)
end

You can tailor your specific needs by reading up on Net:HTTP. Also, I recommend making this an asynchronous task with something like Resque.
