How to Get User Posts from Faceboo Using PHP

Facebook PHP SDK provides an easy way to access Facebook API. The PHP SDK helps to authenticate and login with Facebook account on the web application. After the authentication, various information can be fetched from the user’s Facebook account using Graph API. Facebook Graph API is very useful to retrieve the profile data and feed from the user timeline.

If you want to enhance the Facebook OAuth functionality and get additional information from the FB account, Graph API is the best option. After the authentication with Facebook, you can retrieve the profile and posts data from the user’s account. In this tutorial, we will show you how to fetch the user post from the Facebook timeline with Graph API using PHP.

In this Facebook post parser script, the following functionality will be implemented using PHP.

-> Login with Facebook using PHP SDK v5.
-> Fetch profile information from Facebook using Graph API.
-> Fetch the user’s posts from Facebook Timeline using Graph API.

Create Facebook App

The App ID and App Secret are required to access Facebook API. To generate App ID & Secret create Facebook APP in Developers Panel.

1. Go to the Facebook for Developers and log in with your Facebook account.

2. At the top navigation menu, click the My Apps and select Add New App.
-> Enter the Display Name and Contact Email.
-> Click on the Create App ID button.
-> You will be redirected to the App Dashboard.

3. Navigate to the Settings » Basic page.
-> Specify the App Domains and select the Category of your App.
-> Click Save Changes.

4. At the left navigation menu panel, click the PRODUCTS(+) and navigate to the Add a Product page.
-> Select Facebook Login to Set Up.
-> Select Web as the App platform.
-> Enter the Site URL and Save.

5. Navigate to the Facebook Login » Settings page.
-> In the Valid OAuth Redirect URIs field, enter the Redirect URL.
-> Click Save Changes.

6. In the Settings » Basic page, the App ID and App Secret will be displayed. This App ID and App secret allow you to access Facebook APIs.

Note that: The App ID and App secret need to be specified in the script at the time of Facebook API call. Also, the Valid OAuth Redirect URIs must be matched with the Redirect URL that specified in the script.

Get Permission to Access Feed of Posts

To grants app permission and retrieve the user’s Facebook timeline posts, you need to submit a request for user_posts permission.

-> Go to the App Review » Permissions and Features page.
-> Request for user_posts permission and submit the required information.

Once the review process is completed and approved by Facebook, you will be able to get the user posts from the timeline with Facebook Graph API.

Note that: It will take time to complete the review process by Facebook. Meanwhile, you can test the functionality in development mode.

Create Database Tables

Two tables are required to hold the user’s profile information and feed posts data in the database.

1. The following SQL creates a users table with some basic fields in the MySQL database to store the account information from Facebook.

CREATE TABLE `users` (
 `oauth_provider` enum('','facebook','google','twitter') COLLATE utf8_unicode_ci NOT NULL,
 `oauth_uid` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
 `first_name` varchar(25) COLLATE utf8_unicode_ci NOT NULL,
 `last_name` varchar(25) COLLATE utf8_unicode_ci NOT NULL,
 `email` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
 `gender` varchar(10) COLLATE utf8_unicode_ci DEFAULT NULL,
 `picture` varchar(200) COLLATE utf8_unicode_ci NOT NULL,
 `link` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
 `created` datetime NOT NULL,
 `modified` datetime NOT NULL,
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

2. The following SQL creates a user_posts table in the MySQL database to store the user’s posts information from Facebook.

CREATE TABLE `user_posts` (
 `user_id` int(11) NOT NULL,
 `post_id` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
 `message` text COLLATE utf8_unicode_ci NOT NULL,
 `created_time` datetime NOT NULL,
 `published_by` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
 `attach_type` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
 `attach_title` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
 `attach_image` text COLLATE utf8_unicode_ci NOT NULL,
 `attach_link` text COLLATE utf8_unicode_ci NOT NULL,
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

Facebook SDK for PHP

Facebook PHP SDK is used to authenticate with Facebook API. The files of the Facebook PHP SDK (v5) are included in the facebook-php-graph-sdk/ directory. You don’t need to download it separately, Facebook PHP SDK library is included in our source code.

Database and API Configuration (config.php)

The database settings and Facebook API configuration constant variables are defined in the config.php file.

Database Constants:

  • DB_HOST – Specify the database host.
  • DB_USERNAME – Specify the database username.
  • DB_PASSWORD – Specify the database password.
  • DB_NAME – Specify the database name.
  • DB_USER_TBL – Specify the table name where the user’s account data will be stored.
  • DB_POST_TBL – Specify the table name where the user’s feed data will be stored.

Facebook API Constants:

  • FB_APP_ID – Specify the Facebook App ID.
  • FB_APP_SECRET – Specify the Facebook App Secret.
  • FB_REDIRECT_URL – Specify the Callback URL.
  • FB_POST_LIMIT – Number of posts that will be fetched from the timeline and display in the web page.

Call Facebook API:
The PHP SDK library is used to connect with Facebook API and working with OAuth client.

User Class (User.class.php)

The User class handles the database related operations (connect, insert, update, and delete) using PHP and MySQL.

  • __construct() – Connect to the database as per the credentials specified in the config.php file.
  • checkUser() –
    • Insert or update the user profile data based on the OAuth provider and ID.
    • Returns the user’s account data as an array.
  • getPosts() – Fetch posts data from the user_posts table.
  • insertPost() – Insert post data in the user_posts table.
  • deletePosts() – Delete post data based on the user ID.

class User { 
    private $dbHost     = DB_HOST; 
    private $dbUsername = DB_USERNAME;

Login and Fetch User Feed from Facebook Timeline (index.php)

In this file, the authentication process is hanlded with Facebook API using PHP.

  • Initially, the OAuth URL is generated using the getLoginUrl() method of Login Helper class and Facebook Sign-in button is displayed on the web page.
  • After the authentication with Facebook account, the following happens:
    • The profile info is retrieved from the Facebook account using Facebook Graph API.
    • The account data is inserted into the database using checkUser() function of User class.
    • The user’s account info is stored in the SESSION.
    • The post feed is retrieved from the user’s timeline using the Facebook Graph API (/{user-id}/feed).
    • Fetch the single post info using Facebook Graph API (/{post-id}).
    • Fetch the post attachment info using Facebook Graph API (/{post-id}/attachments).
    • Delete old posts data from the database and insert the latest post data in the database.
  • The Facebook profile details (Name, First name, Last name, Email, Gender, Picture, and Profile link) is displayed on the webpage.
  • The Posts and links which are published by the authenticated user are listed on the web page.
  • The Logout link is generated using getLogoutUrl() method of the login helper class.
// Include configuration file 
require_once 'config.php';

// Remove user data from session 
// Redirect to the homepage 


If you want to add social login feature on the website, Facebook authentication is the most reliable way to allow the user to login with their social account. This script helps you to enhance the Facebook login functionality. The logged-in user can view their timeline posts on the website without visiting Facebook using PHP SDK and Graph API. You can use the Facebook posts parser functionality for many purposes in the web application.
