Turn a list of tag IDs and/or slugs into a list of links to those tags.

== Description ==

Turn a list of tag IDs and/or slugs into a list of links to those tags.

The plugin provides a widget called "Linkify Tags" as well as a template tag, `c2c_linkify_tags()`, to easily indicate 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.

== Installation ==

1. Unzip `linkify-tags.zip` inside the `/wp-content/plugins/` directory for your site (or install via the built-in WordPress plugin installer)
1. Activate the plugin through the 'Plugins' admin menu in WordPress
1. 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.


== Screenshots ==

1. The plugin's widget configuration.


== Frequently Asked Questions ==

= 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>`


== 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); ?>`
`<?php c2c_linkify_tags("43"); ?>`
`<?php c2c_linkify_tags("books"); ?>`
`<?php c2c_linkify_tags("43 92 102"); ?>`
`<?php c2c_linkify_tags("book movies programming-notes"); ?>`
`<?php c2c_linkify_tags("book 92 programming-notes"); ?>`
`<?php c2c_linkify_tags("43,92,102"); ?>`
`<?php c2c_linkify_tags("book,movies,programming-notes"); ?>`
`<?php c2c_linkify_tags("book,92,programming-notes"); ?>`
`<?php c2c_linkify_tags("43, 92, 102"); ?>`
`<?php c2c_linkify_tags("book, movies, programming-notes"); ?>`
`<?php c2c_linkify_tags("book, 92, programming-notes"); ?>`
`<?php c2c_linkify_tags(array(43,92,102)); ?>`
`<?php c2c_linkify_tags(array("43","92","102")); ?>`
`<?php c2c_linkify_tags(array("book","movies","programming-notes")); ?>`
`<?php c2c_linkify_tags(array("book",92,"programming-notes")); ?>`


* `<?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.`


== Filters ==

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: ' ); ?>`
