| Subject: | redirect not working with iframe for non-added user? |
Using a FB webapp, using an iframe, when a FB user has not yet added my
app & I want to redirect them to my 'add' page - the 'redirect' sub in
API.pm doesn't work.
This:
<code>
elsif ($url =~ m{^https?://([^/]*\.)?facebook\.com(:\d+)?}ixms
&& $self->session_uid )
</code>
$self->session_uid is NOT set so it falls thru to doing a regular
redirect with causes an infinite redirect loop.
It's at this step in 'can_display':
<code>
if (!$c->facebook->canvas->get_fb_params->{'added'}) {
</code>
So I have to make my own redirect (I'm using Catalyst) like:
<code>
my $url = $c->facebook->get_add_url(next =>
$c->facebook->get_app_url());
$c->res->body("<script
type=\"text/javascript\">\ntop.location.href=\"$url\";\n</script>");
</code>
At least that's what I think is going on...
thanks!
