Customizing Templates

Version 2.1 of the RW WordPress Plugin includes a brand new template engine allowing for further customization. Advanced WordPress users and developers can use the new template engine to change layouts and rearrange, remove or add components using WordPress Hooks and custom HTML, CSS & PHP.

This post describes customization for our RW Elephant Rental Inventory WordPress Plugin.


We highly recommend following WordPress best practices when adding Theme customizations. It’s rarely a good idea to add customizations directly to your Parent Theme, unless you have full understanding of what that entails (e.g. if you’re using a pre-made Theme to build your site design with that regularly receives updates, customizations made to Parent Theme files will be overwritten when updates are applied). Please use a Child Theme if making customizations to a pre-built Theme.


  1. Make a copy of the “/templates/” folder (found in the root directory of the plugin) and move to the root directory of the current theme. eg: “/wp-content/themes/twentyseventeen/”.
  2. Rename the “/templates/” folder “/rw-elephant/”.
  3. Duplicate “page.php” of the current theme, rename it “gallery-page.php” and place it in the “/rw-elephant/” directory in the theme root. eg: “/wp-content/themes/twentyseventeen/rw-elephant/gallery-page.php”.
  4. Duplicate “single.php” of the current theme, rename it “single-item.php” and place it in the “/rw-elephant/” directory in the theme root. eg: “/wp- content/themes/twentyseventeen/rw-elephant/single-item.php”.

Bundled with the plugin are a number of helper methods to help with various aspects of the plugin such as detecting when on the gallery page, or when viewing a single product.

  • is_rwe_gallery – Determine when the user is viewing the gallery page or any category on the gallery page. eg: “/gallery” or “/gallery/chairs”
  • is_rwe_single – Determine when the user is viewing a single inventory product. eg: “/inventory/item/123”


Pluggable functions are functions built into the core plugin code that can be overridden in another plugin, mu plugin or theme.

  • rwe_title – Function which generates the markup for the product title in the gallery.
  • rwe_thumbnail – Function which generates the markup for the product thumbnail in the gallery.
  • rwe_url – Function which generates the URL for the product in the gallery.


Note: All examples below should be wrapped in a custom function hooked into after_setup_theme.

function custom_remove_actions() {

   // Add action/remove action here...

add_action( 'after_setup_theme', 'custom_remove_actions' );

Here are a few examples of altering the templates with the new template engine.

Example 1: Swap Product Image Slider & Product Content Sides
 * Swap the slider and product content side
 * (ie: Image slider on right, product content on left)
remove_action( 'rw_elephant_product_content', 'rwe_image_slider', 10 );
remove_action( 'rw_elephant_product_content', 'rwe_product_content', 15 );

add_action( 'rw_elephant_product_content', 'rwe_product_content', 10 );
add_action( 'rw_elephant_product_content', 'rwe_image_slider', 15 );
Example 2: Remove Breadcrumbs
// Remove Breadcrumbs
add_filter( 'rw_elephant_inventory_breadcrumbs', '__return_false' );
Example 3: Remove Wishlist Bottom Action Links (Add More Items & Submit Wishlist)
// Remove Action Links From Wishlist Bottom
remove_action( 'rw_elephant_wishlist_bottom', 'rwe_wishlist_action_links', 10 )
