oauth - Facebook Graph API problem -


i've got trouble facebook authentication. when i'm logged, function getuser() returns 0

here's code :

$fb_params = array( 'appid'     => app_id, 'secret'    => secret_id );   $fb = new facebook($fb_params);  echo $fb->getuser(); // uid

someone's got idea?

ps : 'i can no long access $fb->api('/me'), says requires access_token, think it's linked authentication issue...'

thanks

you not authenticating user, application. result, facebook api can't show /me page or respond getuser() call since doesn't know user trying access api on behalf of (ie. "who /me?"). able access publically-accessible information.

you need user authenticate application through oauth2, store access_token returned, , include in future calls (eg. wirqjcey1.3600.1309525200.0-509450630|ed6sar">https://graph.facebook.com/me?access_token=2227470867|2.aqb-_wirqjcey1.3600.1309525200.0-509450630|ed6sar...).

to using php sdk can do

$loginurl = $fb->getloginurl(); echo "<a href='$loginurl'>login facebook</a>";

clicking link , having user authenticate store access_token $_session, , when hit refresh "new facebook( $fb_params );" constructor pick out access token $_session , use future calls, calls $fb->getuser(); return correctly.

there's functioning example in examples folder of sdk, here: https://github.com/facebook/php-sdk. can use try calls while authenticated application (public data access only), , user.
