I got a Problem with the Facebook Login on my Website. The Code Below is my FB-Connect Code. The commented part of the code sign's me in to my Website. My Problem is when i "reactivate" this code it logs me in instandly everytime i visit the page. But i want to log the user in when he clicks the "Login with Facebook"-Button. When I clicks the facebook login button a Popup shows up and nothing happens..
Can i somehow call a JS function when i click the FB-Connect button?
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'xxxxxxxxxxxxxxxxxx', // App ID
status : true,
cookie : true,
xfbml : true,
oauth : true,
});
var login = false;
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
console.log('connected');
login=true;
var uid = response.authResponse.userID;
//this part of the code below redircts me to the part, where i login to my system.
/*var accessToken = response.authResponse.accessToken;
$.ajax({
type: 'POST',
url: '/?eID=login',
data: $(this).serialize(),
success: function(msg) {
alert("LOGIN");
$('#content').load('/live-session/tickets/');
}
});*/
}});
You need to use FB.login function on click on fb connect button and don't use FB.getLoginStatus
FB.login(function(response) {
if (response.authResponse) {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
});
} else {
console.log('User cancelled login or did not fully authorize.');
}
});
From Doc
FB.getLoginStatus allows you to determine if a user is logged in to
Facebook and has authenticated your app.
So, if you don't want to check whether user has logged in on page load, don't call this
When I clicks the facebook login button a Popup shows up and nothing happens..
If you had already authorized the app and authenticated, facebook wont ask you again for login and authorization

I'm using Facebook login in the simplest way, and getting a call back response:
<div id="fb-root"></div>
<script async defer crossorigin="anonymous" src="https://connect.facebook.net/en_US/sdk.js#xfbml=1&version=v6.0&appId=881911462250499&autoLogAppEvents=1"></script>
<script>
window.fbAsyncInit = function() {
FB.getLoginStatus(function(response) {
FB.api('/me', function (response) {
console.log(response);
});
});
}
</script>
I log the response to the console and receive the name and id, but not email address. How can I get the email as well? Upon researching it, it should get it by default, am I wrong?
According to the Fb docs, This is how you do it.
function statusChangeCallback(response) { // Called with the results from FB.getLoginStatus().
console.log('statusChangeCallback');
console.log(response); // The current login status of the person.
if (response.status === 'connected') { // Logged into your webpage and Facebook.
testAPI();
} else { // Not logged into your webpage or we are unable to tell.
document.getElementById('status').innerHTML = 'Please log ' +
'into this webpage.';
}
}
window.fbAsyncInit = function() {
FB.init({
appId : '{app-id}',
cookie : true, // Enable cookies to allow the server to access the session.
xfbml : true, // Parse social plugins on this webpage.
version : '{api-version}' // Use this Graph API version for this call.
});
FB.getLoginStatus(function(response) { // Called after the JS SDK has been initialized.
statusChangeCallback(response); // Returns the login status.
});
};
function testAPI() { // Testing Graph API after login. See statusChangeCallback() for when this call is made.
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
console.log('Successful login for: ' + response.name);
document.getElementById('status').innerHTML =
'Thanks for logging in, ' + response.name + '!';
});
}
You can check login status in this way.
function checkLoginState() { // Called when a person is finished with the Login Button.
FB.getLoginStatus(function(response) { // See the onlogin handler
statusChangeCallback(response);
});
}
By default, fb allows only basic permissions. What you require is additional permission, hence you have to request it this way.
FB.login(function(response) {
// handle the response
}, {scope: 'email,user_likes'});
You can read more about it here. Hope it helps :)
Ok got it, I was confused and it shoudl be here:
FB.api('/me', { locale: 'tr_TR', fields: 'email,name' }, function (response) {
I'm using facebook authentication on my website using javascript sdk. I can get my email and name but I can't get their email, if they're loging in, only their name (it's my fb developer app).
It asks for the login, in case no one is logged in on facebook yet but get nothing happens. If I put an alert where it's supposed to login to my app and it indeed returns the name, just not the email. But if it's me I get both. Why's that?
Here's my code:
<%-- Facebook conection script--%>
<script src="//connect.facebook.net/en_US/all.js"></script>
<script> FB.init({
appId: '334351783684824',
cookie: true,
xfbml: true,
version: 'v2.8'
});
function fbAuthUser() {
FB.login(checkLoginStatus);;
}
function checkLoginStatus(response) {
if (response.status === 'connected') {
FB.api('/me', 'GET', { fields: 'email,name' }, function (response) {
alert(response.email + "; " + response.name);
Ajax(response.email, response.name);
});
}
}
function Ajax(expressao1, expressao2) {
var request = { email: expressao1, nome: expressao2 }
$.ajax({
url: 'login.aspx/LoginExterno',
method: 'post',
contentType: 'application/json',
data: JSON.stringify(request),
dataType: 'json',
success: function (resp) {
window.location.href = resp.d;
},
error: function () { }
})
}
</script>
It's supposed to login and, after getting the data, use that ajax function to access a code behind c# function that redirects the user to the index, if he/she already has an account or to the registry if he/she doesn't have one. It doesn't even go in the Ajax function, because the email parameter is undefined, probably. But when both are present it does.
So, how can I get the email?
Ok, I finally got it. On on FB.Login function, I need to add the scope and the user has to give permission. On my code, it would be like:
FB.login(checkLoginStatus,{scope: 'email'});;
I am getting a Facebook login user from a plugin used on my cordova app, I get that successfully and a new record is just added fine into Parse User class after the login. Now I tried to fetch the user by the email (say abd#user.com) and when I find him, I want to link him to the Facebook user I just logged him in.
Parse.FacebookUtils.logIn(authData,
{
success: function(_user) {
var query = new Parse.Query('User');
query.equalTo('username',data.email);
query.first({
success: function(user){
if (!Parse.FacebookUtils.isLinked(user)) {
// It reaches here
Parse.FacebookUtils.link(_user, null, {
success: function(aUser) {
// But neither here
alert("User logged in with Facebook!");
},
error: function(aUser, error) {
// Nor here
alert("User cancelled the Facebook login or did not fully authorize.");
}
});
}
},
error: function(error){
}
});
},
error: function(error1, error2){
alert("Unable to create/login to as Facebook user");
alert(" ERROR1 = "+JSON.stringify(error1));
alert(" ERROR2 = "+JSON.stringify(error2));
}
});// finish login
I am not sure why the two handlers are not called on Parse.FacebookUtils.link although the Parse.FacebookUtils.isLinked condition is fullfilled and the user appears not to be linked already (see my code above).
I have attempted to implement the Facebook Javascript SDK login into my website but need to store information about the user so that when the user logs back in using Facebook I have information stored about them such as their previous in-website activities. Could I integrate this into a MySQL database?
I think you may searching for the following way of storing logged user information into mysql database,
FB.login(function(response) {
if (response.authResponse) {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
var fbname=response.name;
var fbid=response.id;
$.ajax({
type: "POST",
url: page_for_storing_information,
data: "name="+fbname+"&uid="+fbid,
success: function(msg){
}
});
console.log('Good to see you, ' + response.name + '.');
});
} else {
console.log('User cancelled login or did not fully authorize.');
}
});
I am trying to use JS interface for facebook api and it is my first application for it.
Here is a snippet:
HTML:
<div id="fb-root"></div>
<script src="https://connect.facebook.net/ru_RU/all.js"></script>
<script type="text/javascript">facebook_init();</script>
JS:
function facebook_init() {
FB.init({
appId : '<MY APP ID IS HERE>',
channelUrl : '/media/channel.html', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
FB.api('/me', function(response) {
alert('Your name is ' + response.name);
});
}
channel.html:
<script src="https://connect.facebook.net/ru_RU/all.js"></script>
I have 'Your name is undefined' when I load this page.
But this code
FB.ui({ method: 'apprequests',
message: 'MSG',
title: 'TITLE'});
works as expected.
Could you please help me?
Thanks!
If you log your response variable via console.log(response) you'll see what's wrong:
You'll get an error object with this message:
"An active access token must be used to query information about the current user."
So if you want to get information about the current user you have to send also an Access Token. To get more information about this check the Facebook JS SDK page.
You need to make sure that the user has logged into Facebook and authorized your app, before you call FB.api('/me', ...).
Here's the general information: http://developers.facebook.com/docs/guides/web/#login
To overcome with Undefined problem use the following code:
window.fbAsyncInit = function() {
// init the FB JS SDK
FB.init({
appId : '<APP ID>',
status : true,
xfbml : true
});
// Additional initialization code such as adding Event Listeners goes here
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
alert("connected");
connecter=true;
FB.api('/me', function(user) {
alert(user.name);
alert(user.first_name);
alert(user.last_name);
alert(user.email);
});
}
});
