Turn a string, list, or array of author IDs and/or slugs into a list of links to those authors. Provides a widget and template tag.

Extended Description

The plugin provides a widget called “Linkify Authors” as well as a template tag, c2c_linkify_authors(), which allow you to easily specify authors to list and how to list them. Authors are specified by either ID or slug. See other parts of the documentation for example usage and capabilities.

Template Tags

The plugin provides one template tag for use in your theme templates, functions.php, or plugins.


  • <?php c2c_linkify_authors( $authors, $before = '', $after = '', $between = ', ', $before_last = '', $none = '' ) ?>
    Displays links to each of any number of authors specified via author IDs/slugs


  • $authors
    A single author ID/slug, or multiple author IDs/slugs defined via an array, or multiple authors IDs/slugs defined via a comma-separated and/or space-separated string

  • $before
    (optional) To appear before the entire author listing (if authors exist or if ‘none’ setting is specified)

  • $after
    (optional) To appear after the entire author listing (if authors exist or if ‘none’ setting is specified)

  • $between
    (optional) To appear between authors

  • $before_last
    (optional) To appear between the second-to-last and last element, if not specified, ‘between’ value is used

  • $none
    (optional) To appear when no posts have been found. If blank, then the entire function doesn’t display anything


  • These are all valid calls:

  • <?php c2c_linkify_authors("3 9"); ?>

Outputs something like:

<a href="">Scott</a>, <a href="">Bill</a>
  • Assume that you have a custom field with a key of “Related Authors” that happens to have a value of “3, 9” defined (and you’re in-the-loop).

Outputs something like:

Related authors: <a href="">Scott</a>, <a href="">Bill</a>
  • <ul><?php c2c_linkify_authors("3, 9", "<li>", "</li>", "</li><li>"); ?></ul>

Outputs something like:

<ul><li><a href="">Scott</a></li>
<li><a href="">Bill</a></li></ul>
  • <?php c2c_linkify_authors(""); // Assume you passed an empty string as the first value ?>

Displays nothing.

  • <?php c2c_linkify_authors("", "", "", "", "", "No related authors."); // Assume you passed an empty string as the first value ?>


No related authors.<h3>Hooks</h3>

The plugin exposes one action for hooking.

c2c_linkify_authors (action)

The ‘c2c_linkify_authors’ hook allows you to use an alternative approach to safely invoke c2c_linkify_authors() in such a way that if the plugin were to be deactivated or deleted, then your calls to the function won’t cause errors in your site.


  • same as for c2c_linkify_authors()


Instead of:

<?php c2c_linkify_authors( '19, 28', 'Authors: ' ); ?>


<?php do_action( 'c2c_linkify_authors', '19, 28', 'Authors: ' ); ?>

  2. Activate the plugin through the ‘Plugins’ admin menu in WordPress
  3. Use the provided widget or the c2c_linkify_authors() template tag in one of your templates (be sure to pass it at least the first argument indicating what author IDs and/or slugs to linkify — the argument can be an array, a space-separate list, or a comma-separated list). Other optional arguments are available to customize the output.
