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


== Description ==

The plugin provides a widget called "Linkify Posts" as well as a template tag, `c2c_linkify_posts()`, which allow you to easily specify posts to list and how to list them. Posts are specified by either ID or slug. See other parts of the documentation for example usage and capabilities.

Particularly handy when used in conjunction with the post custom field feature of WordPress. You could define a custom field for "Related Posts" or "Additional Products" and manually list out post IDs, then utilize the function provided by this plugin to display links to those posts in a custom manner.

== Installation ==

1. Install via the built-in WordPress plugin installer. Or install the plugin code 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_posts()` template tag in one of your templates (be sure to pass it at least the first argument indicating what post 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 Posts" widget in one of the sidebar provided by your theme.

== 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 post 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 posts: `</li><li>`

= Does this plugin include unit tests? =

Yes.


== Developer Documentation ==

Developer documentation can be found in [DEVELOPER-DOCS.md](https://github.com/coffee2code/linkify-posts/blob/master/DEVELOPER-DOCS.md). That documentation covers the template tag and hook provided by the plugin.

As an overview, this is the template tag provided by the plugin:

* `c2c_linkify_posts()` : Template tag to display links to each of any number of posts specified via post IDs/slugs. You can customize text to show before and/or after the entire listing, between each post, and what to display (if anything) when no posts are listed.

This is the hook provided by the plugin:

* `c2c_linkify_posts` : Allows use of an alternative approach to safely invoke `c2c_linkify_categories()` in such a way that if the plugin were deactivated or deleted, then your calls to the function won't cause errors in your site.
