I'm planning on using facebook comments plugin for my new blog website and would like to show some stats in the article header (Date, Views, Times Commented, etc) but I can't get the facebook view count to show up. Here's the code I have at the moment:
<div id="fb-root"></div>
<script>
(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/sdk.js#xfbml=1&appId=277028005786031&version=v2.0";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>
At display position
<b>Commented On:</b> <fb:comments-count href="http://example.com/"></fb:comments-count> Times
All this shows on the page is:
Commented On: Times
How can I get it to display the actual number of posts?
As of API 2.0 each API request requires a valid access_token and from your code I see that you are using 2.0, This means sending sensitive data to the Graph which is not safe at all, if you're using JS
A valid access_token
App access_token, combination of in app id & secret in this form {app_id}|{app_secret} (recommended because it doesn't expire)
a user access_token, issued by authorizing an app (expires after 2 hour of issuing, 60 days after extending)
Switch back to API v1.0, available until **April 30th, 2015
(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/sdk.js#xfbml=1&appId={app_id}&version=v1.0";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
You tagged PHP, so the solution i will post is for future use,
comments-count.php
<?php
header('Content-Type: application/json');
$config = array('appId' => '{Your-app-Id}',
'secret' => '{Your-app-secret}');
/** If the $_GET['href'] is set and not empty **/
if( isset($_GET['href']) && !empty($_GET['href']) ) {
$href = $_GET['href'];
$commentsCount = getCommentsCount($href);
// check if the HREF has comments count
if ( array_key_exists('comments', $commentsCount) ) {
$comments = $commentsCount['comments'];
} else {
$comments = 0;
}
echo json_encode( array('meta' => array('code' => 200),
'id' => $commentsCount['id'],
'comments' => $comments,
'shares' => $commentsCount['shares']), JSON_PRETTY_PRINT);
} else {
/** else print the error below (JOSN encoded) **/
header('HTTP/1.1 400');
echo json_encode( array('meta' => array('code' => 400),
'message' => 'href is not provided'), JSON_PRETTY_PRINT);
// JSON_PRETTY_PRINT requires PHP 5.4 or higher, you should remove it if you have 5.3 or lower
}
function getCommentsCount($href) {
global $config;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/v2.0/?id='. $href . '&access_token=' . $config['appId'] . '|' . $config['secret']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$r = curl_exec($ch);
return json_decode($r, true);
}
comments-count.js
;(function($) {
$.fn.facebookCommentsCount = function( options ) {
var $target = this;
/** Plugin default settings **/
var settings = $.extend({
apiPath : 'fb-comments-count/comments-count.php', // Path to `comments-count.php`
zeroComments : null,
oneComment : null,
multipleComments : null
}, options);
return $target.each( function() {
var href = $(this).attr('data-href');
var $this = $(this)
$.ajax({
url: settings.apiPath,
type: 'GET',
dataType: 'json',
data: { href : href },
success: function(data) {
if (data.comments === 0) {
if(settings.zeroComments) {
$this.html(data.comments + ' ' + settings.zeroComments);
} eles {
$this.html(data.comments);
}
} else if (data.comments === 1 ) {
if(settings.oneComment) {
$this.html( data.comments + ' ' + settings.oneComment);
} else {
$this.html(data.comments);
}
} else {
if(settings.multipleComments) {
$this.html( data.comments + ' ' + settings.multipleComments);
} else {
$this.html(data.comments);
}
}
},
error: function(error) {
console.log(error);
}
});
});
};
}(jQuery));
In your page add div, span or p (inline elements are better, div is block)
<div class="fb-comments-count" data-href="{URL}">0</dvi>
<script>
$('.fb-comments-count').facebookCommentsCount();
</script>
