If you know the last part will always be the 4th, you can use a “dirty way” like this:

$url = site_url($this->uri->segment(1).'/'.$this->uri->segment(2).'/'.$this->uri->segment(3));

And then:

echo "<script type='text/javascript'>top.location.href = '".$url."'/testapp';</script>";
// here, though, I don't understan how "testapp" goes into the url..as a segment?

This will create a valid CI url using only the first 3 segments.

Alternatively, you can use the uri_string() function, wich returns only the segment part of the url. On this, you can explode/str_replace/array_pop/do whatever you need to and pass the new elaborated string on the site_url() function wichi will build the correct URL for you.

I don’t understand what “testapp” is there or, do you want to substitute the last segment of your url with that? So that you have, in your example, http://localhost/elephanti/connections/fb_connection/testapp ?

Keep in mind that both uri_string() and site_url() are functions from the URL helper so you need to load it.
