I was trying to find the best way to count number of likes for a facebook page url and after googling a lot and playing with the code, i have a code like the one given below. It outputs the likes, name of the page and then the link. I wish to know:
1. How can i use the html tag to convert the link into hyperlink so that I can have something like "Click here to visit"
2. How can monitor performance of 25+ fb_id on an hourly basis with a sorted order (descending) on likes
<?php
$fb_id = '36922302396';
$url = 'https://graph.facebook.com/' . urlencode($fb_id);
$result = json_decode( file_get_contents($url) );
printf("%s %s %s", $result->likes, $result->name, $result->link);
?>
Edited code as per solution provided
<?php
$fb_id = '36922302396';
$pic = 'https://www.facebook.com/' . urlencode($fb_id) . '/picture?type=square';
$url = 'https://graph.facebook.com/' . urlencode($fb_id);
$result = json_decode( file_get_contents($url) );
echo $result->likes , " " , $result->name , " " , "<a target='_blank' href=\"" . $result->link . "\" ><img src = $pic></a>";
?>
Thanks
For 1)
How about
<?php
$fb_id = '36922302396';
$url = 'https://graph.facebook.com/' . urlencode($fb_id);
$result = json_decode( file_get_contents($url) );
//printf("%s %s %s", $result->likes, $result->name, $result->link);
echo "Link";
?>
You can also use
Link
For 2)
If you know the Page's IDs, then you can just concatenate them to the following :
GET /?ids=40796308305,339150749455906&fields=id,name,likes,talking_about_count
The result looks like the following
{
"40796308305": {
"id": "40796308305",
"name": "Coca-Cola",
"likes": 88365218,
"talking_about_count": 635936
},
"339150749455906": {
"id": "339150749455906",
"name": "Pepsi",
"likes": 33321925,
"talking_about_count": 208761
}
}
For hourly stats, you need to setup your script via cron etc. and write the results to a database.

I tried to build a User search function but i ran into a problem a while ago. My function, which looks like this:
"Select id, username FROM users WHERE username LIKE '%search%'"
Is showing me only the user Janamaris ( userlist is a bit lower )
but as you see jns.drws has also a j in his username ( J = $search ).
So my Problem now i want to show all users with a J in his/her username
So how can i get all users with WHERE?
My Signed Users are [id, username]
Tolkosino
47, Janamaris
48, TheCrazyMan
49, jns.drws

English: Can someone post an example of a foreach e.g. while loop?
The sql is fine and will get all rows you need:
"Select id, username FROM users WHERE username LIKE '%search%'"
If you have problems with upper/lower case then read this:
https://stackoverflow.com/a/2876820/4916265
Example with while
if($result = $mysqli->query($sql)){
if(is_object($result)){
while($row = $result->fetch_assoc()){
echo "<div id=\"content-b\">";
echo "<p class=\"usrsrch\">User ID : " . $row['id'] . "";
echo "<br>";
echo "<p class=\"usrsrch\">Username : . $row['username'] . "";
echo "</div>";
}
} else {
echo 'nix gefunden';
}
}
I'm placing a search form of 6 fields on my home page which includes a text box field named course. I want to show course suggestions while user typing. One more is, I want to show/hide some fields according to the option of first field dropdown. Any help would be appreciated.
You can use jQuery Auto Suggest which is included with WordPress : wp_enqueue_script
With this you can write a form that does a Ajax lookup to the the Ajax URL handler. Which you can add_action onto. AJAX in Plugins
So you can ajax lookup and then on the action side you can just perform a get_posts to match titles, or a raw sql Query. And return what is needed. edit your functions.php.
add_action('wp_enqueue_scripts', 'se_wp_enqueue_scripts');
function se_wp_enqueue_scripts() {
wp_enqueue_script('suggest');
}
add_action('wp_head', 'se_wp_head');
function se_wp_head() {
?>
<script type="text/javascript">
var se_ajax_url = '<?php echo admin_url('admin-ajax.php'); ?>';
jQuery(document).ready(function() {
jQuery('#se_search_element_id').suggest(se_ajax_url + '?action=se_lookup');
});
</script>
<?php
}
add_action('wp_ajax_se_lookup', 'se_lookup');
add_action('wp_ajax_nopriv_se_lookup', 'se_lookup');
function se_lookup() {
global $wpdb;
$search = like_escape($_REQUEST['q']);
$query = 'SELECT ID,post_title FROM ' . $wpdb->posts . '
WHERE post_title LIKE \'' . $search . '%\'
AND post_type = \'post_type_name\'
AND post_status = \'publish\'
ORDER BY post_title ASC';
foreach ($wpdb->get_results($query) as $row) {
$post_title = $row->post_title;
$id = $row->ID;
$meta = get_post_meta($id, 'YOUR_METANAME', TRUE);
echo $post_title . ' (' . $meta . ')' . "\n";
}
die();
}
Use ajax for both. You may have to write some mysql query to retrieve the required fields(post titles or whatever it is) from the table.
I am using AWD Facebook wordpress plugin to allow my visitors to login with their Facebook account information. When a visitor registers on my site I automatically create a new post that is titled with their username and includes their Facebook profile picture as the content. The code for that is below:
function my_create_page($user_id){
$fbuide = 0;
$the_user = get_userdata($user_id);
$new_user_name = $the_user->user_login;
$new_user_avatar = get_avatar($the_user->user_email);
global $AWD_facebook;
$fbuide = $AWD_facebook->uid;
$headers = get_headers('http://graph.facebook.com/' . $fbuide . '/picture?type=large',1);
if(isset($headers['Location'])) {
$url = $headers['Location']; // string
} else {
$url = false;
}
$my_avatar = "<img src='" . $url . "' class='avatar AWD_fbavatar' alt='" . $alt . "' height='" . $size . "' />";
$my_post = array();
$my_post['post_title'] = $new_user_name;
$my_post['post_type'] = 'post';
$my_post['post_content'] = $my_avatar;
$my_post['post_status'] = 'publish';
wp_insert_post( $my_post );
}
add_action('user_register', 'my_create_page');
What I am looking to accomplish is a bit different though. I also want to include a brief biography about the user (currently the post is simply their picture). So when a visitor logs in with AWD Facebook, their needs to be an additional field that allows the user to type in their bio. Then I would be able to grab that info from their user profile and include it in the post. Any ideas on how I can accomplish this? Is there a different way to do this?
I would recommend storing their Facebook picture as metadata and use the content area as their bio for the automatically generated post. So something like this should get you started:
$my_post = array(
'post_title'=>$new_user_name,
'post_type'=>'post',
'post_content'=>'',
'post_status'=>'publish'
);
if( $id = wp_insert_post( $my_post ) ){
update_post_meta($id, 'avatar', $url);
}
Then you can generate the loop like so:
if ( have_posts() ) : while ( have_posts() ) : the_post();
//... stuff here
$avatar = get_post_meta($post->ID, 'avatar', 'true');
the_content();
echo '<img class="avatar AWD_fbavatar" src="'.$avatar.'" alt="'.$alt.'" height="'.$size.'" />';
endwhile;endif;
I have problems with displaying images in atom file. It doesn't include images in feed in google reader, opera or firefox.
As a starting point I did everything like in Listing 6. at [An overview of the Atom 1.0 Syndication Format] But it doesn't work.
Update
It is not problem with hotlink protected images. Described here: How to display item photo in atom feed?
Later I changed feed according to description posted here.
I added:
<media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="path_to_image.jpg" />
But still it doesn't work
I had the same problem when trying to include images as enclosure, but it seemed that the easiest way for me was to include the image with the normal img tag to the html content.
(It's also wrapped in CDATA, which might affect the way Google Reader handles the content. I haven't tried without.)
The following example works for me to make atom feed images visible in Google Reader:
<content type="html">
<![CDATA[
<a href="http://test.lvh.me:3000/listings/341-test-pics?locale=en">
<img alt="test_pic" src="http://test.lvh.me:3000/system/images/20/medium/test_pic.jpg?1343246102" />
</a>
]]>

Wordpress uses the metafield enclosure to set the medias. This is the correct tag according to RSS specification. I have seen people suggest using media:content but if using that make sure to set the XML namespace for it.
Unfortunately due to some dodgy Wordpress code you can not set this dynamically. (Wordpress gets all metafields and then loops through them instead of calling the enclosure directly)
You can set the enclosure on save post. It should be an array with entries of the form "$url\n$length\n$type"
If you want to add the enclosure tags yourself you can do the following:
RSS
add_action( 'rss2_item', 'hughie_rss2_item_enclosure' );
function hughie_rss2_item_enclosure():void
{
$id = get_post_thumbnail_id();
$url = wp_get_attachment_url($id);
$length = filesize(get_attached_file($id));
$type = get_post_mime_type($id);
echo apply_filters( 'rss_enclosure', '<enclosure url="' . esc_url( $url ) . '" length="' . absint( $length ) . '" type="' . esc_attr( $type ) . '" />' . "\n" );
}
ATOM:
add_action( 'atom_entry', 'hughie_atom_entry_enclosure' );
function hughie_atom_entry_enclosure():void
{
$id = get_post_thumbnail_id();
$url = wp_get_attachment_url($id);
$length = filesize(get_attached_file($id));
$type = get_post_mime_type($id);
echo apply_filters( 'atom_enclosure', '<link rel="enclosure" href="' . esc_url( $url ) . '" length="' . absint( $length ) . '" type="' . esc_attr( $type ) . '" />' . "\n" );
}
The only way I found to set the enclosure dynamically is short-circuiting the get_metadata call. You can add checks to make sure that you are in a feed or even the check the stacktrace to make sure.
add_filter('get_post_metadata', 'hughie_get_post_metadata', 10, 5 );
function hughie_get_post_metadata($value, int $object_id, string $meta_key, bool $single, string $meta_type)
{
if (is_feed() && $meta_key === '') {
$backtrace = debug_backtrace();
if (isset($backtrace[7]['function']) && ( $backtrace[7]['function'] === 'rss_enclosure' || $backtrace[7]['function'] === 'atom_enclosure' ) ) {
if (!isset($value['enclosure'])) {
$value['enclosure'] = [];
}
$id = get_post_thumbnail_id();
$url = wp_get_attachment_url($id);
$length = filesize(get_attached_file($id));
$type = get_post_mime_type($id);
$value['enclosure'][] = "$url\n$length\n$type";
}
}
return $value;
}
I want to fetch 'birthdays' of users, and their friends on my website, from their facebook profiles (with their facebook credentials supplied).
Is their a feature in Facebook API/Connect that I can use to fetch these details from facebook as possible on Native Facebook Apps using Facebook API.
I want to store this data in my DB, and users will be asked for their facebook credentials and consent before this is done.
Read the api documentation things like this are easily done. You can do it like this:
$facebook = new Facebook( $apikey, $secret );
$uid = $facebook->require_login();
$friends = $facebook->api_client->friends_get(); // $friends is an array holding the user ids of your friends
foreach( $friends as $f ) {
$data = $facebook->api_client->fql_query( "SELECT birthday_date FROM user WHERE uid=$f" );
// $data[0] is an array with 'birthday_date' => "02/29/1904"
// see api documentation for other fields and do a print_r
}
So recently I wanted to check my friends to see if any of them had their birthday for the current day. Using FQL this is super easy and I encourage you to explore FQL more because it will yield a more efficient solution than, say, what Pierre kindly offered. Here is a small snippet of the code:
$friends = $facebook->api_client->friends_get();
$uids = "";
foreach($friends as $f) {
$uids .= "uid=$f OR ";
}
$query_uids = substr($uids,0,strlen($query_uids)-4);
date_default_timezone_set('UTC');
$current_date = date("m/d");
echo "<br />Searching for birthdays for the given month/day: $current_date<br />";
$data = $facebook->api_client->fql_query( "SELECT name, uid FROM user WHERE ( ($query_uids) AND strpos(birthday_date,'$current_date') >= 0 )" );
if(count($data) > 0) {
foreach($data as $d) {
print_r($d);
}
} else {
echo "<br />No Birthdays Today<br />";
}
require_once('facebook-platform/client/facebook.php');
$facebook = new Facebook(API_KEY, SECRET);
$facebook->require_login();
function getInfo($user_list, $fields)
{
try
{
$u = $facebook->api_client->users_getInfo($user_list, $fields);
return $u;
}
catch (FacebookRestClientException $e)
{
echo $e->getCode() . ' ' . $e->getMessage();
}
}
function getFriendsBirthdays($user_id)
{
$f = $_REQUEST['fb_sig_friends'];
$f = explode(',', $f);
$birthdays = array();
foreach($f as $friend_id)
{
$birthdays[] = getInfo($friend_id, 'birthday');
}
return $birthdays;
}
Do something like that or use the Batch API to do multiple calls at once. Check the Facebook API.
You could fetch it via the API, but Facebook's terms strictly forbid you from storing anything other than their user ID in your database - see the developer wiki for details. You will need to query the API each time.
