I own a website that generates YouTube names, how can I show the user if a channel is already taken or not?
You can use channel->list request for this.
As mentioned in documents, all you need to do is do
channels.list(part="id", forUsername="username")
If this return an empty list, there is no channel with that username.
Also here are some samples to get you started.
You can try
$api = 'https://gdata.youtube.com/feeds/api/users/';
$user = "user";
$headers = get_headers($api . $user, true);
if ($headers[0] == "HTTP/1.0 200 OK") {
// its ok
}

When I try to get photo data by this request
$response = $fb->get('/me/albums');
$albums = $response->getDecodedBody();
foreach($albums['data'] as $album)
{
echo 'Album: '. $album['name'] .'<br/>';
$response = $fb->get('/'. $album['id'] .'/photos');
$photos = $response->getDecodedBody();
foreach($photos['data'] as $photo)
{
$response = $fb->get('/'. $photo['id']);
$data = $response->getDecodedBody();
var_dump($data);
}
}
I get only [ created_time, id ] of each photo. Is some privilege required to get this content?
Do I need to "user_photos" privilege accepted?
I thought that admin may test it without acceptation.
You do need the user_photos permission, but you don´t need to get it approved to make it work for an App admin. You get results, so i assume your authorization is correct. The only thing that is missing are the fields, check out "Declarative Fields" in the changelog: https://developers.facebook.com/docs/apps/changelog#v2_4
What I need
I need to automatically find & download profile picture for user knowing his email address only. Originally, I focused on Facebook considering the amount of people actively using it. However, there seem to be no direct support from their API anymore.
There was similar question here:
How to get a facebook user id from the login email address which is quite outdated and current answers there are "it's deprecated" / "it's not possible"...
EDIT: I've found even better question: Find Facebook user (url to profile page) by known email address (where it is actually explained why and since when this feature isn't supported)
There must be a way...
What makes me think that this should be possible is that Spokeo is somehow doing it:
http://www.spokeo.com/email-search/search?e=beb090303%40hotmail.com
There are some services / APIs offering this kind of feature:
Clearbit
Pipl
...but I haven't found anything free.
Alternatives
If there is some workaround or different approach than using Facebook's API to achieve this, I would like to know. If Facebook is really completely hopeless here, then combination of these: Google+, Linkedin and/or Gravatar could do.
My first (original) attempt:
Once you have Facebook's username or user ID, it's easy to build URL to download the picture. So I was trying to look for Facebook's user IDs using emails with the /search Graph API:
https://graph.facebook.com/search?q=beb090303#hotmail.com&type=user&access_token=TOKEN
which unfortunatelly always ends with "A user access token is required to request this resource."
Using FB PHP API + FB App ID & Secret
I've also tried this: at first I retrieve access_token using app ID and secret and then I'm trying to use it as a part of /search request with curl:
function post_query_url($url, $data) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$res = curl_exec($ch);
curl_close($ch);
return $res;
}
function get_query_url($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$ret = curl_exec($ch);
curl_close($ch);
return $ret;
}
function get_retrieve_app_access_token($app_id, $secret) {
$url = 'https://graph.facebook.com/oauth/access_token?client_id='.$app_id.'&client_secret='.$secret.'&grant_type=client_credentials';
$res = get_query_url($url);
if (!empty($res)) {
$tokens = explode('=', $res);
if (count($tokens) == 2)
return $tokens[1];
}
return null;
}
function post_retrieve_app_access_token($app_id, $secret) {
$url = 'https://graph.facebook.com/oauth/access_token';
$data = 'client_id='.$app_id.'&client_secret='.$secret.'&grant_type=client_credentials';
$res = post_query_url($url, $data);
if (!empty($res)) {
$tokens = explode('=', $res);
if (count($tokens) == 2)
return $tokens[1];
}
return null;
}
function get_id_from_email($email, $accessToken) {
$url = 'https://graph.facebook.com/search?q='.urlencode($email).'&type=user&access_token='.$accessToken;
$res = get_query_url($url);
if (!empty($res)) {
return $res;
}
return null;
}
echo 'Retrieving token...<br>';
$token = post_retrieve_app_access_token('MY_APP_ID', 'SECRET');
echo 'Retrieved token: ' . $token . '<br>';
echo 'Retrieving user ID...<br>';
$id = get_id_from_email('beb090303#hotmail.com', $token);
echo 'Retrieved ID: ' . $id . '<br>';
outputs something like:
Retrieving token...
Retrieved token: 367458621954635|DHfdjCnvO243Hbe1AFE3fhyhrtg
Retrieving user ID...
Retrieved ID: {"error":{"message":"A user access token is required to request this resource.","type":"OAuthException","code":102}}
Other info
Since it's asking for "user access token", I've also tried to go to Facebook's Graph Explorer: https://developers.facebook.com/tools/explorer/
let it generate access token for me and queried:
search?q=beb090303#hotmail.com&type=user&debug=all
That one ends with:
{
"error": {
"message": "(#200) Must have a valid access_token to access this endpoint",
"type": "OAuthException",
"code": 200
}
}
...so Facebook seems kinda hopeless here.
That's exactly why Gravatar exists and why people use Gravatar, users know which public profile image they bind to which e-mail address and they know where to change it.
Your app can have the possibility for users to upload their own profile image and fallback to Gravatar.
If you just try to extract an image from Facebook or Google+, it might freak your users out and it will also be harder for them to know where your service got the profile image from.
Using Gravatar in PHP it is as simple as this:
<?php
$email = "email#server.com";
$default = ""; // absolute url to default image goes here or leave empty for default gravatar image
$size = 200;
$grav_url = "http://www.gravatar.com/avatar/" . md5(strtolower(trim($email))) . "?d=" . urlencode($default) . "&s=" . $size;
header("content-type: image/jpeg");
echo file_get_contents($grav_url);
?>
Apart from that, you can also use Facebook and/or Google+ as external login providers where users can grant your application access to their profile information.
There was a bug: Can't search for user by email after July 2013 Breaking Changes that has been closed as "By Design" with official response:
"The ability to pass in an e-mail address into the "user" search type was removed on July 10, 2013. This search type only returns results that match a user's name (including alternate name)" ~ Joseph Tuấn Anh Phan (Facebook Team)
so probably no direct support from Graph API.
I've tried Graph API Explorer where you can try to play with some FQL too (just need to select version 2.0 as newer versions are not supported anymore), unfortunately query like:
SELECT uid, name FROM user where email = 'some.email#gmail.com'
gives:
"error": {
"message": "(#604) Your statement is not indexable. The WHERE clause must contain
an indexable column. Such columns are marked with * in the tables linked from
http://developers.facebook.com/docs/reference/fql ",
"type": "OAuthException",
"code": 604
}
and reference for table user shows that only uid and third_party_id can be used in WHERE.
You should need access token as well as Facebook id of the user. without knowing them cannot get their profile pic
I think Spokeo might have an agreement with Facebook to access the data? I would not be surprised.
Anyway, if you are on a profile you can maybe search for profile_id in the HTML. It's a hack, not sure if it works.
You could always allow people to comment by logging in with their g+/facebook/whatever account (requires you to do something OpenID-like, though); if they've logged in, you should be able to get the facebook uid.
Also, there's something called libravatar, which allows people to associate pictures with their OpenID or email address (and which falls back to gravatar if they haven't configured anything specifically for libravatar); using that should give you more photos than if you stick to "just" gravatar.
I am using Open graph to get face-book page contents.The issue is that for anonymous user accessing the graph result its showing count of likes,shares and comments to be zero for each post. This is the code which I using for php.
$graph_url = "http://graph.facebook.com?id=".urlencode($feed_url);
$content = json_decode(file_get_contents($graph_url));
$account_url = "https://www.facebook.com/feeds/page.php?id=".$content->id."&format=json";
Here content->id is the facebook page id . Is there any way of getting count of likes,shares and comment for each post with anonymous user itself. Any help will be much appreciated.Thanks in advance.
You cannot access private data as anonymous user. You need an access-token (FB-oAuth) in case with a Facebook Application and Users/Page/App permissions to access private data.
You can try it with fql or graph API. If you try to access "private" data. Make sure your created a facebook app before and unlock all user permissions you need to. Means, Stream Reading I think: https://developers.facebook.com/docs/facebook-login/permissions/v2.2. Without that permission, you cannot access private data.
Public example:
http://graph.facebook.com/386050065267_10153256675935268/comments?summary=true
SELECT like_info.like_count, comment_info.comment_count, share_count
FROM stream
WHERE post_id IN (
SELECT concat(id,'_', substr("https://www.facebook.com/Macklemore/posts/10153256675935268", strpos("https://www.facebook.com/Macklemore/posts/10153256675935268", '/posts')+7, strlen("https://www.facebook.com/Macklemore/posts/10153256675935268")))
FROM profile WHERE username IN (
SELECT substr(url, strpos(url, 'facebook.com/')+13, strpos(url, '/posts')-strpos(url, 'facebook.com/')-13)
FROM object_url
WHERE url = "https://www.facebook.com/Macklemore/posts/10153256675935268"))
Result:
{
"data": [
{
"like_info": {
"like_count": 5506
},
"comment_info": {
"comment_count": 353
},
"share_count": 392
}
]
}
Public data can be fetched like:
http://graph.facebook.com/386050065267_10153256675935268/comments?summary=true
or
https://www.facebook.com/PAGE_ID/posts/POST_ID
enter code here
<?php
$fql = "SELECT share_count, like_count, comment_count ";
$fql .= " FROM link_stat WHERE url = '$url'";
$fqlURL = "https://api.facebook.com/method/fql.query?format=json&query=" . urlencode($fql); // Facebook Response is in JSON $ch = curl_init(); curl_setopt($ch,CURLOPT_URL,$fqlURL);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
$output = curl_exec($ch);
curl_close($ch);
$facebookdata json_decode($output);
echo $facebookdata[0]->share_count;
echo "<br>";
// facebook like count
echo $facebookdata[0]->like_count;
echo " count <br>";
// facebook comment count
echo $facebookdata[0]->comment_count;
It's very easy please try it
I'm trying to use Pubsubhubub to get real time RSS feeds update. I'm using PHP for that purpose.
I subscribed to thenextweb as an example;
$hub_url = "http://pubsubhubbub.appspot.com/";
$callback_url = "http://xx.com/rss/callback.php";
$feed = "http://feeds2.feedburner.com/thenextweb";
$sub = new Subscriber($hub_url, $callback_url);
$status = $sub->subscribe($feed);
I receive The hub returns code 202, and after that a "GET" response to my callback.php with the hub_challenge and other stuff. I followed what the tutorials suggest of echoing this number, and hence, the hub will be able to push updates to my callback.
if ($method == 'GET' && $_GET['hub_mode'] == 'subscribe') {
$challenge = $_GET['hub_challenge'];
header('HTTP/1.1 200 "OK"', null, 200);
header('Content-Type: text/plain');
echo $challenge;
}
That's how I echo the challenge number. The problem here is that I don't get any other messages from the hub even though i have a condition to handle any POST message in my callback.
else if ($method == 'POST') {
$updates = json_decode(file_get_contents("php://input"), true);
//doing stuff with the data here
}
I'm not sure if the problem is with the echo part or after that. Does anyone have similar issues? what am I doing wrong?
I just solved the problem. Apparently I was using a different topic_url, I was using this link: http://feeds.feedburner.com/TheBoyGeniusReport?format=xml. Instead, view the page source and make sure you are using the link inside href. The highlighted link below is what you're supposed to use.

I need to import quotes into vtiger.
I find out it can be be done using vtiger web services API
I find out the reference manual:
https://wiki.vtiger.com/archives/index.php/vtiger510:Webservice_reference_manual
But i can't find any example PHP script, neither what data fields I need to pass to webservice.php.
Please help, I need some guidance.
I have done something like this, I have a quick and (rather) dirty but working solution:
<?php
function createOffer($account_id,$subject,$offerlanguage, $totalamount,$date_submission,$date_decision,$date_start,$assigned_user_id,$quotestage,$winningchance,$description,$productarray){
global $adb;
$endpointUrl = "[your URL]/webservice.php";
$userName="admin";
$userAccessKey = '[your accesskey]';
$httpc = new HTTP_CLIENT();
//getchallenge request must be a GET request.
$httpc->GET($endpointUrl."?operation=getchallenge&username=".$userName);
$response = $httpc->currentResponse();
//decode the json encode response from the server.
$jsonResponse = Zend_JSON::decode($response['body']);
//check for whether the requested operation was successful or not.
if($jsonResponse['success']==false)
//handle the failure case.
die('getchallenge failed:'.$jsonResponse['error']['errorMsg']);
//operation was successful get the token from the reponse.
$challengeToken = $jsonResponse['result']['token'];
//create md5 string concatenating user accesskey from my preference page
//and the challenge token obtained from get challenge result.
$generatedKey = md5($challengeToken.$userAccessKey);
//getchallenge request must be a GET request.
$httpc->post("$endpointUrl",
array('operation'=>'login', 'username'=>$userName, 'accessKey'=>$generatedKey), true);
$response = $httpc->currentResponse();
//decode the json encode response from the server.
$jsonResponse = Zend_JSON::decode($response['body']);
//operation was successful get the token from the reponse.
if($jsonResponse['success']==false)
//handle the failure case.
die('login failed:'.$jsonResponse['error']['errorMsg']);
//login successful extract sessionId and userId from LoginResult to it can used for further calls.
$sessionId = $jsonResponse['result']['sessionName'];
$userId = $jsonResponse['result']['userId'];
$currency_id=1;
$params = array('description'=>$description,'subject'=>$subject,'quotestage'=>$quotestage,'assigned_user_id'=>'2x'.$assigned_user_id,'account_id'=>'3x'.$account_id,'cf_682'=>$offerlanguage,'currency_id'=>'21x'.$currency_id,'taxtype'=>'group','cf_683'=>$date_submission,'cf_684'=>$date_decision,'cf_685'=>$date_start,'cf_766'=>$winningchance);
$urlArgs = "?&total=".$totalamount;
//encode the object in JSON format to communicate with the server.
$objectJson = Zend_JSON::encode($params);
//name of the module for which the entry has to be created.
$moduleName = 'Quotes';
//sessionId is obtained from loginResult.
$params = array("sessionName"=>$sessionId, "operation"=>'create', "element"=>$objectJson, "elementType"=>$moduleName);
//Create must be POST Request.
$httpc->post($endpointUrl.$urlArgs, $params, true);
$response = $httpc->currentResponse();
//decode the json encode response from the server.
$jsonResponse = Zend_JSON::decode($response['body']);
$savedObject = $jsonResponse['result'];
$id = $savedObject['id'];
$id=str_replace("13x", "", $id);
echo $id." offer: ".$subject." created for amount ".$totalamount." for customer: ".$account_id." assigned to: ".$assigned_user_id;
return $id;
}
As you see there are a few custom fields too so you can see how I've handled those.
You can call this function like this:
createOffer($account_id, $subject, $offerlanguage, $totalamount, $date_submission, $date_decision, $date_start, $assigned_user_id, $quotestage, $winningchance, $description, $productarray)
Then you need to add the products too, which I've found the easiest via a separate function as there can be more products per quote...
<?php
function createProducts($productarray,$id) {
$counter = 1;
foreach ($productarray as $prod) {
$query ="insert into vtiger_inventoryproductrel(id, productid, sequence_no, quantity, listprice) values(?,?,?,?,?)";
$qparams = array($id,$prod['prod'],$counter,$prod['pcs'],$prod['price']);
$productadded=$adb->pquery($query,$qparams);
$counter=$counter+1;
}
}
use it like this:
$prodlist = array();
array_push($prodlist,array('prod'=>"prod1",'pcs'=>2,'price'=>1000));
array_push($prodlist,array('prod'=>"prod2",'pcs'=>2,'price'=>100));
createProducts($prodlist,10);
so my logic is like this:
you create the quote with the createOffer function. It returns with the newly created quote's ID
then you build the array of products (I have just the very basic data here) and add that by referencing the quote's ID
Maybe not the most beautiful solution but works.
Maybe you can start like this (according to your reference link).
