bufferapp-php

Simple PHP library for the amazing buffer at https://buffer.com

Why?

There wasn't one listed on Buffer's website and a quick Google search didn't turn one up. For most use cases Buffer's plugins will work just fine, but for those of you looking to pump lots of info into buffer via PHP this may help!

Using this library

Include the file
- Make sure you've got buffer.php included
Create a new Buffer app
- You'll need to register an app with buffer before you can begin
- Initialize like this $buffer = new BufferApp($client_id, $client_secret, $callback_url); The callback_url needs to be the exact same as the app you registered
Start adding buffers!
- Once you're in you really only need to check $buffer->ok to see if you can perform actions, and then $buffer->go($endpoint, $data) to get going!

The Buffer API documentation has a list of the media parameters for creating an update.

Their example here includes media[link], media[title] & media[description].

To get the desired result you will need to use media[picture] and media[thumbnail].

Example

First thing's first: start a session and require buffer.php. We're going to be storing the access_token in the session for now.

	session_start();
	require('buffer.php');

Set this thing up with your credentials and your callback URL. Remember: callback_url must match what you've got in Buffer exactly!

	$client_id = '';
	$client_secret = '';
	$callback_url = 'http://127.0.0.1/callback';

Set up the new buffer client. This is a super simple action that does a few things under the hood. If $_GET['code'] is set on this page it assumes it came from Buffer and will attempt to trade that code for an access_token. If there is an access_token in the session it will be loaded in.

	$buffer = new BufferApp($client_id, $client_secret, $callback_url);

Once we've got an access_token set the $buffer->ok property will read true. It is false by default. Now that we've received access we are free to run queries against Buffer endpoints! Below we pull the list of profiles associated with the logged in buffer user and submit a test update to each one.

	if (!$buffer->ok) {
		echo '<a href="' . $buffer->get_login_url() . '">Connect to Buffer!</a>';
	} else {
		//this pulls all of the logged in user's profiles
		$profiles = $buffer->go('/profiles');
		
		if (is_array($profiles)) {
			foreach ($profiles as $profile) {
				//this creates a status on each one
				$buffer->go('/updates/create', array('text' => 'My first status update from bufferapp-php worked!', 'profile_ids[]' => $profile->id));
			}
		}
	}

Storage

Right now this baby just stores the access_token in $_SESSION['oauth']['buffer']['access_token']. If you are doing something serious with this you should probably rewrite the store_access_token() and retrieve_access_token() methods.

Realistically these methods should be replaced with some sort of abstraction -- pull requests are welcome!
