This plugin provides a jQuery interface for published blogs on the Movable Type Publishing Platform. The interface is responsible for rendering sign in/out/up links on a page based upon the state of a user's session. It exposes event handlers for authentication events so that developers can bind to the DOM handers that respond to a user logging in or out.

This library is meant to service partly as a replacement for the bulk of the standard javascript file that is typically found in every Movable Type template set or theme.

Currently this library is limited to:

  • displaying a greeting to logged in or logged out users
  • rendering login/logout/edit profile links

Getting Started

Before you begin, make sure you have a copy of jQuery 1.3 or greater installed on your system/website. You will need to include this in your web page or Movable Type templates:

<script type="text/javascript" src="jquery-1.3.1.js"></script>

Install Javascript Index Template

Found in this package is a file containing template code that is meant to be published as an index template for any blog that utilizes this jQuery library. You can find this template code in the file called: javascript_mt.mtml.

  1. Navigate to your blog's Design > Templates area.

  2. Click "Create index template."

  3. Cut and paste the contents of javascript_mt.mtml into the newly created template.

  4. Set the output file name to mt.js.

  5. Click "Save and Publish."

Add Your Script Tags

Once your mt.js file has been published you have all that you need to get started. The next step is to add the javascript libraries to your web site. Add this code to the header of your web site.

<script type="text/javascript" src="mt.js"></script>
<script type="text/javascript" src="jquery.mtauth.js"></script>
<script type="text/javascript" src="jquery.mtgreeting.js"></script>

Note: you may need to adjust the paths to each of the scripts above depending upon where they are located on your web server.

Edit Your Web Page

Now let's look at some actual HTML and javascript that you can use on your web site and blog:

    <script type="text/javascript" src="mt.js"></script>
    <script type="text/javascript" src="jquery.js"></script>
    <script type="text/javascript" src="jquery.mtauth.js"></script>
    <script type="text/javascript" src="jquery.mtgreeting.js"></script>
    <script type="text/javascript">
    $(document).ready(function() {
    <div id="greeting"></div>

Customizing Messaging

To customize the messages that are rendered out to your greeting element, the following options can be used when initializing the greet function:

  • loggedInMessage: 'Welcome, %p! %o'
  • loggedOutMessage: '%i or %r'
  • noPermissionMessage: 'Welcome, %p! %o'

The following are the tokens currently supported:

  • %p - profile link, e.g. edit profile
  • %u - user's display name
  • %i - login link
  • %o - logout link
  • %r - register link

Customizing Link Text

The messages above contain tokens that will be replaced with full links tags. To customize the labels for those links, these options can be provided:

  • loginText: 'Sign In'
  • logoutText: 'Sign Out'
  • registerText: 'Sign Up'
  • editProfileText: '%u'


  editProfileText: 'edit profile',
  logoutText: 'logout',
  loggedInMessage: 'Hello, %u. (%p | %o)',
  loggedOutMessage: '%i or %r'

$('#userpic').onauthchange( function( e, u ) {

    $(this).html('Not logged in');
