I would like to parse one newest feed from one page by PHP.
As I readed, FB rejected curl/fopen and another ways to parse some data.
Instead of this i should use FB API, ok i'll take PHP SDK.
$info = json_decode(file_get_contents('https://graph.facebook.com/cocacola/feed?access_token={some_access_token}'));
Fine, it return me feeds from cocacola page, but it require valid access token.
To get access token user should at least once authorize my app, right?
Reuire autorize from user is not the best idea in this website, so maybe someone know the better way to get just one (newest) feed?
All you need to access the feed of a public page is an application access token for your application, you don't need a user's access token. If you don't have an application you must first set one up at http://developers.facebook.com/apps.
Once you have an app set up on Facebook, you can get an application access token here (replace your app ID and secret ID with the values found on the Facebook app page):
https://graph.facebook.com/oauth/access_token?client_id=<YOUR_APP_ID>&client_secret=<YOUR_APP_SECRET>&grant_type=client_credentials
You can use this in your call to the feed page, as per the link in your question.

I am basically building a blog-style application which will post to a facebook page a link and a description whenever a new post is made. Users will not login to the application, so it shouldn't ask the individual posters for their facebook credentials.
I am using the Facebook Version 5 PHP SDK
Basically, the simplest way would be to have it always use my account's access token to obtain the page access token and post as the page every time someone makes a post.
I understand how to do this handoff of tokens and to post as the page, but I don't know how to always obtain the access token for my account to make this transaction without there being an additional step of following a callback url after each post.
Not sure if i understand what you are trying to do, you should not let other users post something on your Page with your Page Token - but there IS an Extended Page Token, and it is valid forever so you could just store it.

I'm building an application for an event so they can directly post their news messages on facebook. I'm trying to use de php SDK V4 for this but there are some parts of the login process I don't understand (still couldn't find a solution after searching for several hours).
My Problem is in the login process. First you have to specify which applicaton you are and give your application secret. Than you have to login to facebook with an account.
But which account should I use for that? The one of their event? Mine?
(I'm an admin of the events page) (this means that all messages will
be posted from mine account while i'm not the poster...sounds pretty
weird..)
Which method should I use to login into facebook? There is a veriaty of methonds like the FacebookRedirectLoginHelper(), the FacebookCanvasLoginHelper() or the Javascript one. However as far is I understand all these helpers for your users to login to their facebook accounts and that's not what I want.
During my search I found some an example of someone who is making a similar system (Facebook Graph API PHP SDK v4 - Post on Page). He/She uses the folowing piece of code for getting a facebook session:
FacebookSession::setDefaultApplication('{APP ID}','{APP SECRET}');
$session = new FacebookSession('{Page Access Token}');
This suggests that you don't need to login into facebook by user but only need a Page Acces Token. However if I understand it correctly (correct me if I'm wrong), to get a Page Acces Token, you first need an User Acces Token (https://developers.facebook.com/docs/facebook-login/access-tokens/#pagetokens). To get an User Acces Token you should be logged in, and than we're back to question 1 and 2 in the beginning of my story.
Or can I just get a Page Acces Token using the following api request (according to https://developers.facebook.com/docs/facebook-login/access-tokens/#pagetokens)
GET /{user-id}/accounts
Using a random user-id as long as the page admin gave this user permission to generate such a token (so the user related to "user-id" shouldn't be logged in while retrieving the Page Acces Token?) .
Sounds like you'll need to use the following flow:
Have the page admin log in with their Facebook account. Make sure to request the manage_pages extended permission. This will give you access to the pages they admin.
Once they grant access to your app, you'll get a short lived user access token. Exchange it for a long lived user access token.
Get the list of the user's pages with /me/accounts. Each page will have an access_token field returned with it. These are all page access tokens. We want to use a long lived user access token to get this list so that all the page access tokens returned will not have an expiration date. They live forever! :)
Use the page access token to post to the wall of the page if you want to post as that page. Use the user access token to post to the wall of the page if you want to post as that user.
And the Facebook Query Builder might make this whole process a lot easier. :)
Hope that helps!
Firstly I am aware that there are a million questions similar to this, but they are all either out of date (Facebook has changed and the instructions no longer work) or don't explain how to do specifically what I am asking.
I'm trying to register an app on Facebook so that I can autopost to the company Facebook page, of which I am an admin.
I'm trying to do this via PHP, with which I have considerable experience (PHP, not Facebook API.)
So far I have registered as a Facebook developer, made a Facebook app, got the appID and secret word, and downloaded the facebook-php-sdk from Github. I have attempted to follow a couple of tutorials but the Facebook developer/app pages have all changed and so the intructions are now invalid.
All I want to do is to be able to post automatically to my page's wall from the server via PHP, as if I posted the status update myself as the page admin. I don't understand how or why this is so difficult.
The Facebook app page has a million settings that I've never heard of and don't seem to be related, then there is no information that gives any direction to do what I want to do.
This is about as far as I've got and I've hit a wall. No idea what to do next. Facebook keeps asking me "Select how your app integrates with Facebook" but their options don't appear to include what I want, which is just to post on my own page. I don't appear to actually be able to use the app yet, as there are various settings its insisting on, like "Canvas URL", which I do not understand, etc. and then I obviously need to set permissions, yet I see no way to do this either.
What do I do?
Setting up an app
You are going to need to authenticate the user who has at least content creator rights on your page. So you need to choose 'Website with Facebook Login' and enter your website url.
You'll also have to enter the domain (website url without protocol)
Keep it in sandbox mode while you test it you can edit that later.
You don't really have to worry about other settings as the permissions to ask can be added directly in your php code.
"Online" Access
To logging and post directly to facebook you'll need to retreive an access token
Getting an access token
Here is a basic run down:
Get user to login and allow app with appropriate permissions (manage_pages, publish_stream) if he hasn't
Retreive user access token
Query /me/accounts with user access token to get the page id & access token
Then all you have to do is make your API call with id & access token to post on facebook
"Offline" Access
In order to post without having to logging (usefull if you aren't the only one posting) you need a permanent extended token. So you basically should have a separate script that you'll run once to retrieve that extended token and store it.
Getting an extended access token
To be able to post without the user being logged in you need a permanent access token for your page.
Here is a basic run down:
Get user to allow app with appropriate permissions (manage_pages, publish_stream)
Retreive user access token
Change user access token for extended user access token
Here is how I do this step (you could also use curl)
$token_url = "https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&client_secret=YOUT_APP_SECRET&grant_type=fb_exchange_token&fb_exchange_token=OLD_TOKEN";
$accessToken = #file_get_contents($token_url);
Then
Query /me/accounts with user extended access token to get the page
Change page access token for extended access token (same code as
above)
(The last step shouldn't be necessary according to the doc as you should get an extended page token when you query /me/accounts with an extended user token but in my case it didn't work)
And you get a permanent access token that only expires if the user changes password or disallows the app. All you have to do is store it with the page's id and retreive it wherever you need an API call to post to facebook.
The php sdk is pretty well documented so you shouldn't run into any problem a google search can't fix. Look for post september 2012 threads the flow hasn't changed since neither did the php sdk much.
I need implement a functionality in save/update function, of my customers system:
In each save/update, I need get this informations, and send to a Facebook Page (every the same Page).
But my problem is: this system is used by a lot users, and some users do not have a Facebook account, so: How can I post in same Page without login?
I know the offline_access are removed, so, what the best solution in this situation?
I don't find any way, to get the Page Access Token
I create some APP in my personal account of Facebook, but, when I try post in this Page, I get a access unauthorized for this user/app
Sorry for my english.
For you to post updates on to the Page's feed there are few things you would require
An User with administrative or content publishing permission to atuhorize your application with manage_pages Extended permissions. If you have implemented the login, you can add these permissions there, or alternatively you can use Graph Explorer with your application selected to get started.
After you have been authorized then you can retrieve the Page Access Token by querying /me/accounts which would return data as shown in this documentation. You can then utilize the access token you retrieve for the corresponding page to do your job of posting updates.
I have a site written in PHP.
I need to get a list of events from a Facebook page and publish them on a page of the PHP site.
This call works but but it require an access token:
https://graph.facebook.com/mtv/events?access_token=....
I want publish the list on the PHP site without requiring an user to login with Facebook.
Is this possible? Is there any way that I can get a permanent token to hardcode in my PHP code?
offline_access Enables your
application to perform authorized
requests on behalf of the user at any
time. By default, most access tokens
expire after a short time period to
ensure applications only make requests
on behalf of the user when the are
actively using the application. This
permission makes the access token
returned by our OAuth endpoint
long-lived
.
I don't know if this is valid for Graph API.
EDIT:
I think your only chance is to use DOM Parser and parse http://www.facebook.com/MTV?v=app_2344061033, this shouldn't be hard at all.
If it is a public page you should be able to get the events using any access token with offline_access rights.
