Template Tags

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

Functions

• <?php c2c_linkify_categories( $categories, $before = '', $after = '', $between = ', ', $before_last = '', $none = '' ) ?>
  Displays links to each of any number of categories specified via category IDs/slugs

Arguments

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

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

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

• $between
  (optional) To appear between categories

• $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 categories have been found. If blank, then the entire function doesn’t display anything

Examples

• These are all valid calls:

<?php c2c_linkify_categories(43); ?>

<?php c2c_linkify_categories("43"); ?>

<?php c2c_linkify_categories("books"); ?>

<?php c2c_linkify_categories("43 92 102"); ?>

<?php c2c_linkify_categories("book movies programming-notes"); ?>

<?php c2c_linkify_categories(array("43","92","102")); ?>

<?php c2c_linkify_categories(array("book","movies","programming-notes")); ?>

<?php c2c_linkify_categories(array("book",92,"programming-notes")); ?>

• <?php c2c_linkify_categories("43 92"); ?>

Outputs something like:

<a href="http://yourblog.com/category/books">Books</a>, <a href="http://yourblog.com/category/movies">Movies</a>

• <ul><?php c2c_linkify_categories("43, 92", "<li>", "</li>", "</li><li>"); ?></ul>

Outputs something like:

<ul><li><a href="http://yourblog.com/category/books">Books</a></li><li><a href="http://yourblog.com/category/movies">Movies</a></li></ul>

• <?php c2c_linkify_categories(""); // Assume you passed an empty string as the first value ?>

Displays nothing.

• <?php c2c_linkify_categories("", "", "", "", "", "No related categories."); // Assume you passed an empty string as the first value ?>

Outputs:

No related categories.

Filters

The plugin exposes one action for hooking.

c2c_linkify_categories (action)

The ‘c2c_linkify_categories’ hook allows you to use an alternative approach to safely invoke c2c_linkify_categories() 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.

Arguments:

• same as for c2c_linkify_categories()

Example:

Instead of:

<?php c2c_linkify_categories( "43, 92", 'Categories: ' ); ?>

Do:

<?php do_action( 'c2c_linkify_categories', "43, 92", 'Categories: ' ); ?>

Frequently Asked Questions

Q. What happens if I tell it to list something that I have mistyped, haven’t created yet, or have deleted?
A. If a given ID/slug doesn’t match up with an existing category then that item is ignored without error.

Q. How do I get items to appear as a list (using HTML tags)?
A. Whether you use the template tag or the widget, specify the following information for the appropriate fields/arguments:

Before text: <ul><li> (or <ol><li>)
After text: </li></ul> (or </li></ol>)
Between categories: </li><li>
