I am trying to integrate our DB with the facebook API , really new on this so I would appreciate some help.
I am always getting 0
Using
$uid = $facebook->getUser()
I had a look to similar issues but didn't find a related solution.
PHP
if($_REQUEST['action']=="signup" && $_REQUEST['auth']=="facebook" && !empty ($_REQUEST['auth']) && !empty ($_REQUEST['action']) )
{
require_once('libs/facebook/src/facebook.php');
$config = array();
$config['appId'] = 'xxxx';
$config['secret'] = 'xxxxxx';
$facebook = new Facebook($config);
$uid = $facebook->getUser();
echo $uid;
}
//else {} normal sign up here with all the error checking
HTML
<div class="fb-login-class">
<div class="fb-login-button" autologoutlink="true" scope="publish_stream" perms="email,user_birthday" data-show-faces="false"
data-width="200" data-max-rows="1"></div>
</div>
JAVASCRIPT / JQUERY
window.fbAsyncInit = function() {
// init the FB JS SDK
FB.init({
appId : 'XXXX, // App ID from the app dashboard
channelUrl : '//WWW.XXXX.com', // Channel file for x-domain comms
status : true, // Check Facebook Login status
xfbml : true // Look for social plugins on the page
});
// Additional initialization code such as adding Event Listeners goes here
// will be handled.
FB.Event.subscribe('auth.authResponseChange', function(response) {
// Here we specify what we do with the response anytime this event occurs.
if (response.status === 'connected') {
loginfunction();
} else if (response.status === 'not_authorized') {
FB.login(function(response) {},{scope: 'email'});
} else {
FB.login(function(response) {},{scope: 'email'});
}
});
};
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_GB/all.js#xfbml=1&appId=XXXXX";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
function loginfunction() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function (response) {
console.log(response);
/*I can see all the data here and the button also changes so I know that I am logged in */
var data = 'action=signup&username=' + response.username + '&firstname=' + response.first_name + '&gender=' + response.gender + '&lastname=' + response.last_name + '&email=' + response.email + '&dob=' + "xxxx" + '&auth=facebook';
/*What's the point in passing all these parameters through ? only need to pass &auth=facebook and action=signup I guess the rest can be manipulated anyway so what's the point
need to get them from PHP SDK (server side ajax call) */
$.ajax({
type: "POST",
url: "actions/do_signup.php",
data: data,
beforeSend: function (html) {},
success: function (html) {
if (html == "success") {
window.location.replace("index.php");
} else {}
}
});
}, {
scope: 'email'
});
}
thanks
EDIT tried that only with PHP still failed
require('facebook.php');
$facebook = new Facebook( array (
'appId' => 'xxx',
'secret' => 'xxxx',
'cookie' => true
)
);
if ($_REQUEST['act']=="fb")
{
//$next_url = $facebook->getLoginStatusUrl($params);
if ($facebook->getUser()) {
$userProfile = $facebook->api('/me');
$uid = $facebook->getUser();
// do logic
echo $uid ;
echo "ok";
} else {
echo "problem";
$loginUrl = $facebook->getLoginUrl($params = array('scope' => user_birthday,read_stream,'redirect_uri' => 'http://xxxx/index.php?act=success'));
header('Location:' . $loginUrl);
}
}
else if ($_REQUEST['act']=="success")
{
try{
$_SESSION['fbAT'] = $facebook->getAccessToken();
}catch(Exception $e){
trigger_error("FB AccessToken: " . $e->getMessage());
}
$facebook->setAccessToken($_SESSION['fbAT']);
if ($facebook->getUser()) {
$uid = $facebook->getUser();
$userProfile = $facebook->api('/me');
// do logic
echo $uid ;
echo $userProfile;
echo "ok";
} else {
$uid = $facebook->getUser();
echo $uid ;
echo "still problem";
}
Some steps that I have tried:
- Sandbox Mode is disabled and I have confirmed the app id and secret as well...
- Tried adding header : header('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"');
- Added cookie' => true
- Try calling it from a static page not through ajax still 0
- Only website is used under facebook basic tab
- Under advanced app type is set to web
- Under permissions default activity is public
- Made sure that fb_ca_chain_bundle.crt is in the same dir that facebook.php also tried to use a different dir (the same with my php file)
- Trying only PHP and getLoginUrl with additional scope to get access.
- Trying getting and setting an access token
In window.fbAsyncInit I have set cookie and oauth to true and this worked!
cookie:true,
oauth : true.
Make sure that In your php you also have
cookie' => true.
That will enable the php code to integrare with the JS.
And you need to make sure the user has logged in with:
$loginUrl = $facebook->getLoginUrl(array( 'scope' => 'read_stream,etc..'));
The scope is defined by the permissions stated here
After that you should be able to do:
$user = $facebook->api("/me");
Which will get an array associated with the user, $user['id'] is probably the one you'll want to store as well as any other information like email address - be sure to request for email in the scope
Hope that solves the problem!
