justinstern / wc-measurement-price-calculator-custom-unit.php
Last active December 17, 2015 15:29
This demonstrates how you would setup a new hypothetical weight unit named XX which is equal to 5000 lbs. The new unit is added to the woocommerce admin, and then conversions are provided to the weight standard unit of 'lbs', as well as the conversion from 'XX' to lbs. This approach could be adapted to create new units for the other measurement …
<?php
add_filter( 'woocommerce_catalog_settings', 'add_woocommerce_weight_unit_xx' );
/**
* This adds the new unit to the WooCommerce admin
*/
function add_woocommerce_weight_unit_xx( $settings ) {
foreach ( $settings as &$setting ) {

Created November 25, 2013 04:02
Display a lightbox of the product catalog image, rather than linking to the product page. Drop this code snippet into the bottom of your theme's functions.php file. Implementation note: at line 25 we're stripping the image dimensions out of the original image source in order to try and display the full sized image. So if the catalog thumbnail is…
<?php
// Code to display catalog images in a lightbox follows:
add_action( 'wp_enqueue_scripts', 'frontend_scripts_include_lightbox' );
function frontend_scripts_include_lightbox() {
global $woocommerce;
if ( is_shop() || is_product_category() ) {
