Developer Documentation

Developer documentation can be found in 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_categories() : Template tag to display links to each of any number of categories specified via category IDs/slugs. You can customize text to show before and/or after the entire listing, between each category, and what to display (if anything) when no categories are listed.

This is the hook provided by the plugin:

  • c2c_linkify_categories : 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.

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. Use provided widget or the c2c_linkify_categories() template tag in one of your templates (be sure to pass it at least the first argument indicating what category 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 Categories” widget in one of the sidebars provided by your theme.
