Posts a Twitter update when you update your WordPress blog or post to your blogroll, using your chosen URL shortening service. Requires PHP 5. 

== Description ==

WP to Twitter posts a Twitter status update from your WordPress blog using your URL shortening service to provide a link back to your post from Twitter. 

The plugin supports a default Tweet template for updating or editing posts and pages, supports your custom post types, and also allows you to write a custom Tweet for each post which says whatever you want, using a selection of custom shortcodes to generate your text. 

Additional features include: 

* Use tags as Twitter hashtags
* Use alternate URLs in place of post permalinks
* Support for Google Analytics
* Support for XMLRPC remote clients

Any status update you write which is longer than the available space will be truncated by the plugin. This applies to both default messages and to your custom messages.

Upgrade to [WP Tweets Pro](http://www.joedolson.com/articles/wp-tweets-pro/) to gain additional features.

* Eliminated features: Author's Twitter account posting; Use of additional service to post to Twitter on a second account. These features are not possible with simple OAuth authentication; they require XAuth. This makes the features of extremely limited value, since you, as the user, would be required to apply for XAuth permissions on your own installation. I regret the necessity to remove these features. Both options will still function with Twitter-compatible API services using Basic authentication.

* Provided a substitute function for hosts not supportin mb_substr().
* Fixed a bug where a hashtag would be posted on edits when posting updates was not enabled for edits.
* Put Cli.gs change revisions on hold barring updates from Pierre at Cli.gs

= 1.5.1 =

* Because that's what I get for making last minute changes.

= 1.5.0 =

* Due to a large number of problems in the 1.4.x series, I'm launching a significant revision to the base code earlier than initially planned. This is because many of these features were already in development, and it's simply too much work to maintain both branches of the code.

== Frequently Asked Questions ==

= Where are your Frequently Asked Questions? Why aren't they here? =

Right here: [WP to Twitter FAQ](http://www.joedolson.com/articles/wp-to-twitter/support-2/). I don't maintain them here because I would prefer to only maintain one copy. This is better for everybody, since the responses are much more likely to be up to date!

= How can I help you make WP to Twitter a better plug-in? =

Writing and maintaining a plug-in is a lot of work. You can help me by providing detailed support requests (which saves me time), or by providing financial support, either via my [plug-in donations page](http://www.joedolson.com/donate.php) or by [upgrading to WP Tweets Pro](http://www.joedolson.com/articles/wp-tweets-pro/). Believe me, any small donation really makes a difference!
