MM-Tweeter

Conditional Auto Tweeter written in PHP

• Using OAuth Library by Matt Harris: https://github.com/themattharris/tmhOAuth
• Running via CLI PHP
• Design an application to use Matt Harris' library as a function to auto tweet events based on existing conditions

Usage

• Build a HTTP request with the following variables
  • source (Your Source - predetermined)
  • secret (Your secret - predetermined)
  • post_date (When the tweet should be posted + 5 minutes)
  • content (this is what you want tweeted)
• Example:

  http://api.midsouthmakers.org/mm-tweeter/?source=samplesource&secret=samplesecret&post_date=2012-05-07%2011:46:10&content=Sample Tweet

  • $_POST or $_GET methods should work in the same manner.
• Execute the request
• Currently debugging information is turned on.
• Please report any errors.

Current Functionality

• Using MidsouthMakersDev Twitter account
• Able to be run from the command line to post static tweets.
• Able to be run from a url to post static tweets.
• Checks pending table and checks if their post date < current time
• Cron running every 30 minutes to post any pending

To Be Done

• Need to handle adding to pending table
• Need to handle adding to history
• Need to handle Remove from pending
• Cron local system to test for pending tweets
• Testing
• Need to provide fallback if no $post_date supplied.
• Need to ensure response code making it back to user
• Need to add warning if $content > 160 characters OR Blank. Solved by: they're using a twitter api, they should self limit <= 160 characters
  • Perhaps ability for source to query their tweets based on history/pending?\
• Need ensure $content is not NULL in addpending() Solved by: checking if $content = before addpending()
• Log post attempts? Check error codes so we're not hammering away at twitter Solved by: $attempts checking: default 3

Goals

• Take input from multiple sources
• Reliably validate source of all incoming data
• Use access list or secret hash to prevent abuse

Database Schema

• Pending Table

CREATE TABLE IF NOT EXISTS `pending` (
  `id` int(6) NOT NULL AUTO_INCREMENT,
  `content` varchar(160) NOT NULL,
  `post_date` datetime NOT NULL,
  `added` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  `source` varchar(255) NOT NULL,
  `attempts` int(1) NOT NULL,
  `last_error_code` int(3) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 ;

• History Table

CREATE TABLE IF NOT EXISTS `history` (
  `id` int(6) NOT NULL AUTO_INCREMENT,
  `content` varchar(160) NOT NULL,
  `post_date` date NOT NULL,
  `added` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  `source` varchar(255) NOT NULL,
  `response_code` int(4) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 ;

• Secrets Table

CREATE TABLE IF NOT EXISTS `secrets` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `source` varchar(255) NOT NULL,
  `secret` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 ;
