Introduction

Have you created your own WordPress plugin? Do you want to showcase it on your WordPress powered blog? Do you want the showcase on your website to show up-to-date information?

If you answered yes to the above then ‘WordPress Plugin Information Shortcode’ may be for you. This plugin utilises the WordPress API to retrieve information about a plugin and display a showcase of it on your website.

Features

Easily display a showcase of your WordPress plugin on your WordPress powered website. Each showcase includes the following:

• Plugin banner, as shown on WordPress.org, if the plugin does not have a banner then a generic one is used
• Plugin name
• 5 star rating of the plugin, including a visual representation of the 5 star rating
• Description of the plugin
• Number of times the plugin has been downloaded
• Tags that the plugin is listed with on WordPress.org
• A download button, which links directly to the latest version on WordPress.org
• A more information button, which links to the plugins page on WordPress.org

All the above is formatted in a similar way to the plugin page, as it would display on WordPress.org. Information is also formatted in a responsive way; giving a good appearance on mobile devices as well as desktop web browsers.

Installation

1. Upload the plugin files to the ‘/wp-content/plugins/plugin-name’ directory, or install the plugin through the WordPress plugins screen directly.
2. Activate the plugin through the ‘Plugins’ screen in WordPress.
3. Add the shortcode [wpplugin slug="my-plugin-name"] to the desired location on your blog.

Usage

Once ‘WordPress Plugin Information Shortcode’ has been installed on your WordPress powered website and the plugin has been activated:

1. Find the slug of your plugin by viewing the plugin on WordPress.org. The slug is the final part of the URL, which is usually formatted: ‘my-plugin-name’.
2. On the page or blog post where you wish to showcase your plugin add the following shortcode: [wpplugin slug="my-plugin-name"]
3. Save the page or blog post, your plugin showcase should now be displayed on your page or blog post.
