Front-End Implementation? (2 posts)

    Is there any kind of front-end implementation for the "Allow new posts to your Facebook Timeline" functionality? Everything else I'm doing keeps the user out of the backend (login, logout, profile edit, etc.), and I'd love to keep in line with that with this plugin.

    I don't see anything in the settings, but is there any recommendation for how to implement this manually?

    I found the div that appears to be doing the work:

    <div class="facebook-login" data-scope="person">Allow new posts to your Facebook Timeline</div>

    And copied the login.js file from the plugin to my theme's JS directory, enqueueing it when needed. The JS file loads, but when the link is clicked I receive a "FB is not defined" error on line 51. I'm assuming that this is because another part of the plugin is not being integrated.

    Any thoughts on this? Thanks!

    I'm currently working on some better author login flows for the user profile pages but the logic is essentially the same.

    If you are building a custom front-end you will need to first load the Facebook SDK for JavaScript (that FB variable you're missing):

    1. The JavaScript file is registered with the facebook-jssdk handle and enqueued when used in the plugin (or your own code)
    2. The asynchronously loaded Facebook SDK for JavaScript executes the fbAsyncInit function when it's ready to start accepting bindings or code that depends on the existence of the JavaScript SDK. You can queue a function to be executed at or after this function happens using the JavaScript function FB_WP.queue.add (see Google Analytics add-on for an example). You can also add JavaScript code to be executed in the facebook_jssdk_init_extras filter

    Then you're looking at associating the Facebook account of the current viewer with their WordPress user account. The plugin stores data about the Facebook user account in the fb_data user meta field. The fields stored can change in different versions of the plugin; you can see the current values in admin/login.php.

    Time to prompt an author for permission to access his Facebook account and optionally post to Facebook Timeline on his behalf. You'll need:

    1. JavaScript code calling FB.login with no scope of you just want to associate an account (e.g. for identifying an author) or a publish_actions scope if you want to be able to publish to Facebook on behalf of the author.
    2. Check for a successful state in the callback, then write the user meta values
