Overview

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:


    <html>
      <head>
        <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() {
          $('#greeting').greet();
        });
        </script>
      </head>
      <body>
        <div id="greeting"></div>
      </body>
    </html>

Usage

Configuration Options

  • `mode` – Controls whether links for signing in, registering
    will be constructed using the open source version, or will
    link to the Movable Type Pro equivalents. Possible values
    are: “mtos” and “mtpro”. (default: mtos)
  • `loggedInMessage` – The message to display in the target
    element when the user is logged in. (default: ‘Welcome, %p! %o’)
  • `loggedOutMessage` – The message to display in the target
    element when the user is NOT logged in. (default: ‘%i or %r’)
  • `noPermissionMessage` – The message to display in the target
    element when the user does NOT have permission to leave a
    comment. (default: ‘Welcome, %p! %o’)
  • `loginText` – The text to use in the login link.
    (default: ‘Sign In’)
  • `logoutText` – The text to use in the logout link.
    (default: ‘Sign Out’)
  • `registerText` – The text to use in the register link.
    (default: ‘Sign Up’)
  • `editProfileText` – The text to use in the edit profile link.
    (default: ‘%u’)
  • `isPreview` – A boolean value indicating whether a user is
    currently previewing an entry or comment. (default: false)
  • `returnToURL` – An optional return to URL that will override
    typical defaults. This controls the page a user will return
    after logging in, out or registering.

The following settings are set via the mt.js file (inside the
index template you published previously).

  • `mt.entry.id` – The ID of the current entry in context. This is used
    when constructing return to URLs for commenting forms.
    (default: 0)

    is only valid for Movable Type Pro users. (default: mt-cp.cgi)
  • `mt.blog.comments.script` – The name of the comment script.
    (default: mt-comment.cgi)
  • `mt.links.signIn` – The sign in URL for this blog.
  • `mt.links.signOut` – The logout URL for this blog.
  • `mt.links.signUp` – The register URL for this blog.
  • `mt.blog.id` – The ID of the blog currently in context.
  • `mt.blog.registration.required` – Whether registration is required for
    the current blog or not. (default: false)
  • `mt.blog.staticWebPath` – The URL to the Movable Type static web path.
  • `mt.cookie.name` – The name of the cookie storing session data.
  • `mt.cookie.domain` – The domain of the cookie storing session
    data.
  • `mt.cookie.path` – The path of the cookie storing session data.
  • `mt.cookie.timeout` – The length of time the cookie being set
    to store session data will last. Time is expressed in
    seconds. (default: 14400)

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 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’

Example


    $('#greeting').greet({
      editProfileText: 'edit profile',
      logoutText: 'logout',
      loggedInMessage: 'Hello, %u. (%p | %o)',
      loggedOutMessage: '%i or %r'
    });

Events and Callbacks

There are a number of events that this plugin will fire when specific
conditions occur or are met. They are:

  • onAuthedUser – fired when a user is determined to be authenticated
  • onUnauthedUser – fired when a user is determined to be logged out
