This plugin was build of the fantastic Advanced Custom Fields plugin created by Elliot Condon, and was made so that referencing custom fields is easier. Here, you can see a full list of all your currently used field which is sortable by clicking on the headers, and should you need to learn more about the field or edit it, clicking the label name will take you to the field group’s page so you can do what you need to. The table sorting functionality incorporates the Tablesorter jQuery plugin by Christian Bach. Docs can be found at http://tablesorter.com/docs/.
*Note: This doesn’t display fields in your theme. It just gives you a complete list of your fields that you can reference easily and allows you to edit the field groups easily.
I tried to mark up the code for this plugin with lots of comments in hope that people can understand how it is working and expand on this functionality. Oh yeah, and all the function and variable names are based off Buster Bluth from Arrested Development.

This plugin will let you manage the post references. It is like “node reference” in Drupal CMS module functionality.
Use Reference Settings page to configure publications connections.
After configuring step you will see additional metabox(s) on post editor page. Now you can choose articles of referenced post types to attach it to article you edit.
Plugin stores connected article list to post metas. For template you can use, for example, get_post_meta($post->ID, ‘_ref_ID’, true) to receive that list. As ‘ref_ID’ you should use a meta key configured on Referenced settings page earlier.
Plugin allow you to configure widgets to view the list(s) of attached articles.
