Auto Post On Facebook Using PHP

To Post On Facebook Automatically It Takes Only Three Steps:-

  1. Create A Facebook App
  2. Get Facebook Access Token
  3. Make a PHP file and define methods to Post On Facebook

Step 1. Create A Facebook App

Before creating Facebook App you need to download Facebook PHP SDK and it requires PHP 5.2.0 or higher for PHP curl extension.

Now we have to create Facebook App go to https://developers.facebook.com/apps and follow the instructions.

Step 2. Get Facebook Access Token

To get Access Token you have to set callback URL for the Facebook app to get the result. Then authorize the app for permissions on https://developers.facebook.com/docs/facebook-login/permissions/v2.2 and then get the access Token.

Make sure renew your Facebook Token After 60 days because Facebook Access token will expires in 60 days.

Step 3. Make a PHP file and define methods to Post On Facebook

We make a PHP file and save it with a name autopost.php 

<?php
require_once("FacebookSDK/facebook.php");
class FacebookApi 
{
	
 var $consumer;
 var $token;
 var $method;
 var $http_status;
 var $last_api_call;
 var $callback;
 var $connection;
 var $access_token;
 
 function __construct($data)
 {
  $config = array();
  $config['appId'] = $data['consumer_key'];
  $config['secret'] = $data['consumer_secret'];
 
  $this->connection = new Facebook($config);
 
 }
 
 function share($title, $targetUrl, $imgUrl, $description, $access_token)
 {
  $this->connection->setAccessToken($access_token);
  $params["access_token"] = $access_token;
  
  if(!empty($title))
  {
   $params["message"] = $title;
   $params["name"] = $title;
  }
  
  if(!empty($targetUrl))
  {
   $params["link"] = $targetUrl;
  }
  
  if(!empty($imgUrl))
  {
   $params["picture"] = $imgUrl;
  }
  
  if(!empty($description))
  {
   $params["description"] = $description;
  }
 
  // post to Facebook
  try 
  {
   $ret = $this->connection->api('/me/feed', 'POST', $params);
  }
  catch(Exception $e) 
  {
   $e->getMessage();
  }
 
  return true;
 }
 
 function getLoginUrl($params)
 {
  return $this->connection->getLoginUrl($params);
 }
 
 function getContent($url) 
 {
  $ci = curl_init();
  /* Curl settings */
  curl_setopt($ci, CURLOPT_URL, $url);
  curl_setopt($ci, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ci, CURLOPT_HEADER, false);
  curl_setopt( $ci, CURLOPT_CONNECTTIMEOUT, 10 );
  curl_setopt($ci, CURLOPT_SSL_VERIFYPEER, false);
 
  $response = curl_exec($ci);
  curl_close ($ci);
  return $response;
 }
 
}
?>

<?php
$access_token = Your_Access_Token;
$facebookData = array();
$facebookData['consumer_key'] = Your_key;
$facebookData['consumer_secret'] = Your_Secret;
 
$title = Post_Title;
$targetUrl = Post_URL;
$imgUrl = Image_URL;
$description = Post_Description;
