Make your own

Create your CSS Creature by tweeting to @csscreatures. You can customize color, personality, and more!

Examples:

@csscreatures happy teeth turquoise
@csscreatures #db2 tiny hungry
@csscreatures moustache lightblue tooth winking
@csscreatures cyclops #62822B teeth

Creatures take roughly 15-30 seconds to cook. Refresh this page and you'll see your creature here soon.

CSS Creatures are generated from 100% all-natural HTML and fresh-squeezed CSS.

You can read that at http://tools.ietf.org/html/draft-hammer-oauth. Some of the +terms will differ from those Twitter uses as well. + +client credentials - Consumer key/secret you get when registering an app with Twitter. +temporary credentials - Previously known as the request token. +token credentials - Previously known as the access token. + +Parameters +========== + +There are a number of parameters you can modify after creating a TwitterOAuth object. + +Switch an existing TwitterOAuth install to use version 1.1 of the API. + + $connection->$host = "https://api.twitter.com/1.1/"; + +Custom useragent. + + $connection->useragent = 'Custom useragent string'; + +Verify Twitters SSL certificate. + + $connection->ssl_verifypeer = TRUE; + +There are several more you can find in TwitterOAuth.php. + +Extended flow using example code +================================ + +To use TwitterOAuth with the Twitter API you need *TwitterOAuth.php*, *OAuth.php* and +client credentials. You can get client credentials by registering your application at +[dev.twitter.com/apps](https://dev.twitter.com/apps). + +Users start out on connect.php which displays the "Sign in with Twitter" image hyperlinked +to redirect.php. This button should be displayed on your homepage in your login section. The +client credentials are saved in config.php as `CONSUMER_KEY` and `CONSUMER_SECRET`. You can +save a static callback URL in the app settings page, in the config file or use a dynamic +callback URL later in step 2. In example use https://example.com/callback.php. + +1) When a user lands on redirect.php we build a new TwitterOAuth object using the client credentials. +If you have your own configuration method feel free to use it instead of config.php. + + $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET); // Use config.php client credentials + $connection = new TwitterOAuth('abc890', '123xyz'); + +2) Using the built $connection object you will ask Twitter for temporary credentials. The `oauth_callback` value is required. + + $temporary_credentials = $connection->getRequestToken(OAUTH_CALLBACK); // Use config.php callback URL. + +3) Now that we have temporary credentials the user has to go to Twitter and authorize the app +to access and updates their data. You can also pass a second parameter of FALSE to not use [Sign +in with Twitter](https://dev.twitter.com/docs/auth/sign-twitter). + + $redirect_url = $connection->getAuthorizeURL($temporary_credentials); // Use Sign in with Twitter + $redirect_url = $connection->getAuthorizeURL($temporary_credentials, FALSE); + +4) You will now have a Twitter URL that you must send the user to. + + https://api.twitter.com/oauth/authenticate?oauth_token=xyz123 + +5) The user is now on twitter.com and may have to login.
