Hello Reader's, If you are making the code for facebook page likes details and you want to know if the user has already liked your page or not, Then you can use the following library code for that :-
<html>
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<style type="text/css">
div#container_notlike, div#container_like {
display: none;
}
</style>
</head>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'YOUR_APP_ID', // App ID
channelUrl : 'http(s)://YOUR_APP_DOMAIN/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.getLoginStatus(function(response) {
var page_id = "YOUR_PAGE_ID";
if (response && response.authResponse) {
var user_id = response.authResponse.userID;
var fql_query = "SELECT uid FROM page_fan WHERE page_id = "+page_id+"and uid="+user_id;
FB.Data.query(fql_query).wait(function(rows) {
if (rows.length == 1 && rows[0].uid == user_id) {
console.log("LIKE");
$('#container_like').show();
} else {
console.log("NO LIKEY");
$('#container_notlike').show();
}
});
} else {
FB.login(function(response) {
if (response && response.authResponse) {
var user_id = response.authResponse.userID;
var fql_query = "SELECT uid FROM page_fan WHERE page_id = "+page_id+"and uid="+user_id;
FB.Data.query(fql_query).wait(function(rows) {
if (rows.length == 1 && rows[0].uid == user_id) {
console.log("LIKE");
$('#container_like').show();
} else {
console.log("NO LIKEY");
$('#container_notlike').show();
}
});
} else {
console.log("NO LIKEY");
$('#container_notlike').show();
}
}, {scope: 'user_likes'});
}
});
};
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));
</script>
<div id="container_notlike">
YOU DON'T LIKE ME :(
</div>
<div id="container_like">
YOU LIKE ME :)
</div>
</body>
</html>
An now open the channel.html file and just write the following code:-
<script src="//connect.facebook.net/en_US/all.js"></script>
