Linkify Tags

Description

The plugin provides a widget called “Linkify Tags” as well as a template tag, c2c_linkify_tags(), which allow you to easily specify tags to list and how to list them. Tags 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.

Functions

  • <?php c2c_linkify_tags( $tags, $before = '', $after = '', $between = ', ', $before_last = '', $none = '' ) ?>
    Displays links to each of any number of tags specified via tag IDs/slugs

Arguments

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

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

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

  • $between
    (optional) To appear between tags

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

Examples

  • These are all valid calls:

  • <?php c2c_linkify_tags("43 92"); ?>

Outputs something like:

<a href="http://yourblog.com/archives/tags/books">Books</a>, <a href="http://yourblog.com/archives/tags/movies">Movies</a>
  • <?php c2c_linkify_tags("43, 92", "<li>", "</li>", "</li><li>"); ?></ul>

Outputs something like:

<ul><li><a href="http://yourblog.com/archives/tags/books">Books</a></li><li><a href="http://yourblog.com/archives/tags/movies">Movies</a></li></ul>
  • <?php c2c_linkify_tags(""); // Assume you passed an empty string as the first value ?>

Displays nothing.

  • <?php c2c_linkify_tags("", "", "", "", "", "No related tags."); // Assume you passed an empty string as the first value ?>

Outputs:

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

The plugin exposes one action for hooking.

c2c_linkify_tags (action)

The ‘c2c_linkify_tags’ hook allows you to use an alternative approach to safely invoke c2c_linkify_tags() 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_tags()

Example:

Instead of:

<?php c2c_linkify_tags( "43, 92", 'Tags: ' ); ?>

Do:

<?php do_action( 'c2c_linkify_tags', "43, 92", 'Tags: ' ); ?>

Installation

  1. Install via the built-in WordPress plugin installer. Or download and unzip linkify-tags.zip inside the plugins directory for your site (typically wp-content/plugins/)
  2. Activate the plugin through the ‘Plugins’ admin menu in WordPress
  3. Optional: Use the c2c_linkify_tags() template tag in one of your templates (be sure to pass it at least the first argument indicating what tag 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.
  4. Optional: Use the “Linkify Tags” widget in one of the sidebars provided by your theme.

FAQ

What happens if I tell it to list something that I have mistyped, haven’t created yet, or have deleted?

If a given ID/slug doesn’t match up with an existing tag then that item is ignored without error.

How do I get items to appear as a list (using HTML tags)?

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 tags: </li><li>

Does this plugin include unit tests?

Yes.

I was searching for a widget that could make tags in a minimal widget just like this! It works flawlessly and it can be customized to fit any WordPress website.
