I'm using the PHP SDK on my site to let the users login using their FB acc.
After clicking on the login button there is a popup which asks for basic permissions. If the user click on Allow, my app can get the required data, it works all very well.
I'd like to make a callback for when the user click on the "Don't allow" button to show a message "For logging in to this website you have to provide us basic information. Please try again."
I know it's possible, i saw it once at another page, but after 2 hours of desperate search i decided to step back to SO :)
Thanks in advance!

In the doc for the login function, there is a parameter
* - cancel_url: the url to go to after the user cancels
*
...
public function getLoginUrl($params=array()) {
Which seems like it would do the trick. So you would invoke with something like
getLoginUrl(array(
'cancel_url' => 'http://yoursite.com/deny_callback.php',
...
yes like brian says, in that cancel url you can put any message too, you can use the same index.php or like:
getLoginUrl(array(
'cancel_url' => 'http://yoursite.com/index.php?message=For logging in to this website you have to provide us basic information. Please try again&try_outs=1',
or something like that.
