WordPress – Promote a Post in a Widget

capabilities covered
Amazon Web Services

Here’s a WordPress plugin that will allow you to feature a single item in a widget, until you tell it to automatically expire.

Download Promoted Posts Widget v0.2  Download from WordPress

As taken from the readme file:


Description

Simple widget to display (promote) a specific post/page. Provides a list of from all public post types to choose an entry to promote until a specified date. When this “promotion” expires, you can either display a static message or use another post/page instead.


Installation

  1. Upload the plugin folder to your plugins directory /content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Add the Widget “Promoted Content” to a sidebar

Frequently Asked Questions

What are the options?

  • Title: The displayed widget title – leaving it blank will use the post title (if you override the default, see Hooks)
  • Feature Expires: until what date (YYYY-MM-DD) to show the promoted post; after which fall back to the default
  • Feature Post: choose from the dropdown of public post types to promote
  • Default: display this entry instead after the expiration
  • Trim summary to: if no excerpt is provided, shorten the post content to this number of words

Note that you can select the most recent post from the dropdown options.

How can I change the defaults?

If you don’t specify certain options, the widget will use builtin defaults. Override these with the following hook:
[php]
add_filter(‘abt_promo_post_defaults’, ‘YOUR_HOOK’);
[/php]

where YOUR_HOOK is a function that takes an array and returns the following settings:

[php]
function promo_widget_defaults($settings){
return array(
#’title’ => ‘Latest From MY SITE’, // disable to use post title
‘display’ => ‘Check out our new video! Credit goes to … <p><a class="archive" href="/category/news">News Archive</a></p>’,
‘url’ => ‘#’,
‘image’ => ‘<img src="’ . get_stylesheet_directory_uri() . ‘/images/g_video.jpg" alt="Latest from MY SITE">’,
);
}
[/php]

What else can I use?

Two static methods are available for “embedding” the widget in code – basically just the internal processing used by the widget function.

abtcore_feature_widget::display_promo($args, $before_title, $after_title) 

which uses the following

abtcore_feature_widget::get_promo($args) 

to get either the promoted post or the default. $args will contain an array of the widget options (title, expire, promo, default, trim).

Function get_promo will return an array of (title, display, url, and image) to display_promo where it gets combined with the defaults from the hook to output the widget HTML.
