Get Facebook Page Feed with PHP + Guzzle

readme.md

Get Facebook Page Feed

It is simple wrapper class written in php to fetch posts from certain Facebook page.

Currently I am using Facebook graph API with cool guzzle and dotenv

Tested in PHP 5.6, 7.0 and 7.1

Requirement

• PHP 5.6+

Installation

Step 1: Getting Facebook App

• Go to Facebook developer website
• Click "Add a New App" and fill in details
• On your Dashboard, get the "App ID" and "App Secret"
• Yeah, you are ready to code

Step 2: Install from composer

composer require xmhafiz/fb-page-feed

Alternatively, you can specify as a dependency in your project's existing composer.json file

{
   "require": {
      "xmhafiz/fb-page-feed": "^1.1"
   }
}

Usage

After installing, you need to require Composer's autoloader and add your code.

Default (maximum post is 100)

$data = fb_feed()->setAppId($fbAppId)
        ->setSecretKey($fbSecretKey)
        ->setPage($fbPageName)
        ->fetch();

Custom Maximum Post Shown

// only show 5 post maximum
$data = fb_feed()->setAppId($fbAppId)
        ->setSecretKey($fbSecretKey)
        ->setPage($fbPageName)
        ->feedLimit(5)
        ->fetch();

Filter By Keyword

// only show 5 post maximum
$data = fb_feed()->setAppId($fbAppId)
        ->setSecretKey($fbSecretKey)
        ->setPage($fbPageName)
        ->findKeyword("#JomPay")
        ->fetch();

Change Request Field

// only show 5 post maximum
$data = fb_feed()->setAppId($fbAppId)
        ->setSecretKey($fbSecretKey)
        ->setPage($fbPageName)
        ->fields("id,message") //default 'id,message,created_time'
        ->fetch();

Code Example

Change the $fbSecretKey and $fbAppId based on the "App ID" and "App Secret" in Step 1

<?php

require_once 'vendor/autoload.php';

$fbSecretKey='580c7...';
$fbAppId='237...';
$fbPageName='LaravelCommunity';

$response = fb_feed()->setAppId($fbAppId)->setSecretKey($fbSecretKey)->setPage($fbPageName)->findKeyword("#AirSelangor")->fetch();

//or

$response = fb_feed()->setCredential($fbAppId, $fbSecretKey)->setPage($fbPageName)->findKeyword("#AirSelangor")->fetch();

header('Content-type: application/json');
echo json_encode($data);

Using ENV

FB_SECRET_KEY=absbo123o233213
FB_APP_ID=123123123123
FB_PAGENAME=pagename

Then, Just

$response = fb_feed()->findKeyword("#AirSelangor")->fetch();

Method

Method	Param	Description
setAppId	String	FB Application ID (Default is in .env)
setSecretKey	String	FB Application Secret ID (Default is in .env)
setCredential	String, String	Set Both Secret and App Id (Default is in .env)
