Basically I would like to know if my visitor is already a fan of my Facebook Page or not.
I tried looking a while and pages.isFan is the best solution so far.
http://developers.facebook.com/docs/reference/rest/pages.isFan/
But pages.isFan need user id (uid), which I can only get if they installed or grant access to my Facebook apps.
My question is, is there a way just to get the uid of my visiting user without ask them to grant access to my Facebook apps?
This code should do the trick:
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
if (empty($data["page"]["liked"])) {
/* Not Fan */
}
else {
/* Fan */
}

Windows 10 Store UWP apps can use StoreContext.RequestRateAndReviewAppAsync function, or simply a URL like this ms-windows-store://review/?ProductId=9WZDNCRFHVJL, to display a user rating window for the app:
I prefer the URL method since I can simply invoke it via ShellExecute method.
But my question is how do I find out if the user had already rated my app, so that I don't display that rating window again?
This is unfortunately not possible, but there is probably a good reason for it - if developers were able to check this programmatically, they could "cheat the system" by giving users who rated some bonuses/perks for reviewing the app.
Currently there is no such api can directly tell if the user already rated the UWP app, but you could use roaming data in your app which keeps your app's app data in sync across multiple devices.
If the user has rated your app, you can set "Yes" in the RoamingSettings, if the value from RoamingSettings is "No", you can display that rating window again. You could determine whether the rating is successful, e.g. in StoreContext.RequestRateAndReviewAppAsync method, the ExtendedJsonData property of the StoreRateAndReviewResult class contains a JSON-formatted string that indicates whether the rating request was successful. By ExtendedJsonData property, you can know if the rating is successful and then set the value to "Yes" in the RoamingSettings.
private async void Button_Click(object sender, RoutedEventArgs e)
{
ApplicationDataContainer RatingSettings = ApplicationData.Current.RoamingSettings;
//initialization
if (RatingSettings.Values["isRated"] == null)
{
RatingSettings.Values["isRated"] = "No";
}
var isRatedStr = RatingSettings.Values["isRated"].ToString();
if (isRatedStr == "No")
{
//display the rate windows
if (//if rated successfully)
{
RatingSettings.Values["isRated"] = "Yes";
}
}
}
Or you can use the Get app ratings and Get app reviews methods in the Store analytics API to programmatically retrieve the ratings and reviews from your customers in JSON format. For more details, you can refer to this document.
I know that it is possible to enroll users in an engagement plan from with Sitecore by adding them to a specific state in the plan when they visit a campaign URL, adding them when they submit a Web Forms for Marketers Form, and manually adding them in the Supervisor interface.
Additionally, I know that you can use the API to add a user as described here:
http://briancaos.wordpress.com/2013/06/03/programming-for-sitecore-dms-engagement-plans/
However, that method requires a username.
I would like to enroll anonymous users in an engagement plan when they visit any page represented by a particular template in Sitecore (ie, page from the Product template). Is this possible using the API?
To expand on my above comment, and to supplement your own answer, here's a processor that you could add to the after the ItemResolver in the httpRequestBegin pipeline that would achieve the desired result. It is a very basic version that you could embellish as you see fit
class CampaignRedirect
{
public void Process(HttpRequestArgs args)
{
var request = HttpContext.Current.Request;
// must not already have the querystring in the URL
if(request.QueryString["sc_camp"] != null &&
request.QueryString["sc_camp"] != "XXXXXXXX")
return;
// must have a context item
if(Sitecore.Context.Item == null)
return;
var item = Sitecore.Context.Item;
// must be the right template
if(item.TemplateID.ToString() != "{XXXXXXXXX-XXXX-XXXXXX}")
return;
var basicUrl = LinkManager.GetItemUrl(item);
var response = HttpContext.Current.Response;
response.Redirect(basicUrl + "?sc_camp=XXXXXXX");
}
}
If you're not familiar with adding processors, take a look here.
Per Sitecore support, this is not currently possible. However, I was able to achieve what I wanted by adding a jQuery AJAX call to the campaign URL to the sublayout used by the page type in question. Naturally this only works for clients with JS enabled, but for my purposes, that is not an issue.
<script type="text/javascript">$(function() { $.get('/?sc_camp=[campaignid]'); });</script>

I found a way to do this via the Sitecore API. This is rough and needs to check for null values, exceptions, etc., but it does work:
string cookieVal = Request.Cookies["SC_ANALYTICS_GLOBAL_COOKIE"].Value;
List<Guid> guids = new List<Guid>() {
new Guid(cookieVal)
};
Guid automationStateId = new Guid("{24963AE9-1C8C-4E18-8EEE-01BC249D1F1B}");
Guid automationId = Sitecore.Context.Database.GetItem(new Sitecore.Data.ID(automationStateId)).ParentID.ToGuid();
Sitecore.Analytics.Automation.Data.AutomationManager.Provider.CreateAutomationStatesFromBulk(guids, automationId, automationStateId);
I am using parse sdk for backend management for my game. For user signup/login parse api ask for parameter tokenExpiration. I have no idea how to get it from facebook unity sdk.
https://www.parse.com/docs/unity_guide#fbusers-signup
Task<ParseUser> logInTask = ParseFacebookUtils.LogInAsync(accessToken, userId, tokenExpiration);
Got this problem solved by myself using debug_token. Here is the right code on how to do it.
FB.API("/debug_token?input_token="+FB.AccessToken+"&access_token="+FB.AccessToken,Facebook.HttpMethod.GET, AccessTokenCallback);
function AccessTokenCallback(response:String){
Debug.Log(response);
var access = JSON.Parse(response);
Debug.Log("Token Expiration is: "+access["data"]["expires_at"].Value);
}
If you will print the response it will give you a JSON with all information about the access token and you can take whatever info you need about an access token.
Open FacebookAccessTokenEditor.cs and replace original line 81:
formData["batch"] = "[{\"method\":\"GET\", \"relative_url\":\"me?fields=id\"},{\"method\":\"GET\", \"relative_url\":\"app?fields=id\"}]";
by these two:
string getExpiresAt = ",{\"method\":\"GET\", \"relative_url\":\"debug_token?input_token="+accessToken+"\"}";
formData["batch"] = "[{\"method\":\"GET\", \"relative_url\":\"me?fields=id\"},{\"method\":\"GET\", \"relative_url\":\"app?fields=id\"}"+getExpiresAt+"]";
Then open FacebookEditor.cs and in method MockLoginCallback, just before line 220:
isLoggedIn = true;
insert the following lines:
var tokenData = (Dictionary<string, object>)MiniJSON.Json.Deserialize(responses[2]);
var expiresAt = (long)((Dictionary<string, object>)tokenData["data"])["expires_at"];
accessTokenExpiresAt = FromTimestamp((int)expiresAt);
also, add the missing function FromTimestamp which you can copy from AndroidFacebook.cs or IOSFacebook.cs or jus copy from here:
private DateTime FromTimestamp(int timestamp)
{
return new DateTime(1970, 1, 1, 0, 0, 0, 0).AddSeconds(timestamp);
}
Finally, you can call the parse method like you do on IOS or Android or Web:
Task<ParseUser> logInTask = ParseFacebookUtils.LogInAsync(FB.UserId, FB.AccessToken, FB.AccessTokenExpiresAt);
Note: As I have worked on the code, I am not sure of the original line numbers, but I think they are correct. Also, this does not reflect the best coding practices, but since it is used only in a debug context, they're good enough for me.
I'm trying to pull a list of connected users in Firebase to simply populate a select dropdown. My problem is that I can't seem to access the child objects properly.
Using connectedUsers.userName (see below code) works but only for my own user data, it doesn't pull anything else.
It seemed to me like changing "myUserRef.on" to "userListRef.on" and using something like "snapshot.child('userName').val()" should work but it just throws undefined. The same goes for "connectedUsers.child.userName", I'm sure I'm missing something simple here.
In the below code by changing to "userListRef.on('child_added', function(snapshot)" I can successfully add and remove user data from Firebase, and log all of the objects to the console and all data looks fine when I drill down the objects. I just need a way to access that data so I can put all connected users into a select dropdown or remove them from it when they disconnect.
var userListRef = new Firebase('https://myaccount.firebaseIO.com/users/');
var myUserRef = userListRef.push();
// ADD USER DATA TO FIREBASE
var userId = $('#myIdInput').val();
var userName = $('#nameInput').val();
myUserRef.push({userId: userId, userName: userName});
// READ USER OBJECTS AND FIRE ADDUSER FUNCTION
myUserRef.on('child_added', function(snapshot) {
var connectedUsers = snapshot.val();
console.log(addUser);
//addUser(connectedUsers.userId, connectedUsers.userName);
});
// ADD USER TO SELECT DROPDOWN
function addUser(userId, userName) {
var modSelect = $('#tsmmodsendto');
modSelect.append($('<option></option>').attr("value", userId).text(userName));
}
// READ USER OBJECTS AND FIRE REMOVEUSER FUNCTION
myUserRef.on('child_removed', function(snapshot) {
var connectedUsers = snapshot.val();
console.log(removeUser);
//removeUser(connectedUsers.userId, connectedUsers.userName);
});
// REMOVE USER TO SELECT DROPDOWN
function removeUser(userId, userName) {
var modSelect = $('#tsmmodsendto');
modSelect.append($('<option></option>').removeAttr("value", userId).text(userName));
}
// ON DISCONNECT REMOVE USER DATA FROM FIREBASE
myUserRef.onDisconnect().remove();
The code you've written won't work properly because each user is writing to:
/users/PUSH_ID/PUSH_ID
And is then listening at:
/users/PUSH_ID
So every client is going to be listening only to its own data and will never see anyone else's data. In order to view other people's data, you need to all be listening / writing to the same path.
In your question you mention you see "undefined" if you change to listening at /users. Could you simplify your code, and use that approach, and perhaps then I can provide a more helpful answer?
Or if I'm not understanding correctly, please simplify and clarify your question.
I am trying to create an EventReceiver for a blog site (for the Posts list) and am having some trouble getting it working. I want to change the Created By column to Anonymous. Basically I have this whole thing working in a console application, however, that will only change the Created By column names when the console application is executed.
I need it to change the Created By whenever a new item is added to the list. My code is below....how do I modify this to use in an EventReceiver project??? Since I already tell the EventReceiver project the URL I want the EventReceiver attached to, I'm not sure what I can remove from this code, right now it just doesn't do anything, no error and no changing of the Created By column when I debug.
using (SPSite site = new SPSite("http://test-sharepoint/subsite/"))
{
using (SPWeb web = site.OpenWeb())
{
SPList list = web.Lists["Posts"];
SPListItemCollection listItemCollection = list.Items;
foreach (SPListItem listItem in listItemCollection)
{
SPFieldUserValue userName = new SPFieldUserValue(web, 22, "Anonymous");
listItem["Author"] = userName;
listItem["Editor"] = userName;
listItem.Update();
}
web.Update();
}
}
EDIT: Code is in ItemAdded method
EDIT #2: This is trying the same code except without the loop and using properties.ListItem, this was my attempt in a Event Recevier project but no luck. It just doesn't change the Created By field, or any field for that matter (I tried the Title as well)
SPSite site = new SPSite("http://test-sharepoint/subsite/");
SPWeb web = site.OpenWeb();
SPFieldUserValue userName = new SPFieldUserValue(web, 22, "Anonymous");
properties.ListItem["Author"] = userName;
properties.ListItem["Editor"] = userName;
properties.ListItem.Update();
*Also from my understanding the SPFieldUserValue will grab either a User or a SharePoint User Group (Permissions) so in my code, the 22 grabs the SharePoint User Group that I want and "Anonymous" is the user from that group...
EDIT #3: More progress, this code works without issues for a list, however, not for the Posts or Comments lists, for those it does not change the Created By field. Could it be because of the approve/reject for all items??? Whether approved orpending it still does not show annonymous, BUT like I mentioned, it works fine in a different list.
public override void ItemAdded(SPItemEventProperties properties)
{
base.ItemAdded(properties);
SPSite site = new SPSite("http://test-sharepoint/hr/blog/"); //SPContext.Current.Site;
SPWeb web = site.OpenWeb();
SPFieldUserValue userName = new SPFieldUserValue(web,22,"Anonymous");
SPListItem currentItem = properties.ListItem;
//currentItem["Title"] = userName; //DateTime.Now.ToString();
currentItem["Author"] = userName;
currentItem["Editor"] = userName;
currentItem.SystemUpdate();
}
**EDIT #4: Alright I found my issue, when creating the project I chose Custom List as my list to attach to but I needed to choose Posts or Comments and now the above code works!!!
But now I have another problem, all posts on the blog are first submitted for approval...and due to this the event receiver doesn't seem to work for users other than the admin. It works fine for the admin account where I can just directly publish a post or comment but for a user with Contribute permissions whose posts are submitted for approval still shows their name on the Manage Posts page...what could I do about this? Any ideas?**
The code that works:
public override void ItemAdded(SPItemEventProperties properties)
{
base.ItemAdded(properties);
SPSite site = new SPSite("http://test-sharepoint/hr/blog/"); //SPContext.Current.Site;
SPWeb web = site.OpenWeb();
SPFieldUserValue userName = new SPFieldUserValue(web, 23, "Anonymous");
SPListItem currentItem = properties.ListItem;
currentItem["Author"] = userName;
currentItem["Editor"] = userName;
currentItem.SystemUpdate();
}
In response to edit #4, when working with SharePoint, if code works when executed by the administrator account, but does not work when executed by a "normal" account, permissions are likely to blame.
See the answer to the question SharePoint/WSS: Modify “created by” field? for an example of an SPItemEventReceiver that modifies the Author field.
Note: Many SharePoint developers recommend against the use of RunWithElevatedPrivileges and suggest using impersonation instead. See my answer to the question In which situation use SPSecurity.RunWithElevatedPrivileges with superusertoken? for more details.
