Inspired by Woo Total Sales this shortcode allows you to display Total Revenue earned for multiple WooCommerce products, product categories, product tags etc.

Examples:

// Display Total Purchased for two specific products
[cd-purchased-total product_ids="16,19"]

// Display Total Purchased for all products in two product categories
[cd-purchased-total product_cats="40,42"]

// Display Total Purchased for all products in two product tags
[cd-purchased-total product_tags="30,22"]

// Display Total Purchased for all published & draft products in a specific category
[cd-purchased-total product_cats="40" product_status="publish,draft"]

// Display Total Purchased for a specific product in all completed & pending orders
[cd-purchased-total product_ids="16" order_status="wc-completed,wc-pending"]

// Display Total Purchased for two specific products and round the total to have no decimals
[cd-purchased-total product_ids="16,19" round="0"]

// Display Total Purchased for two specific products and add 10 to the total
// math supports plus (+), minus (-), multiply (*), division(/)
[cd-purchased-total product_ids="16,19" math="+10"]

// Display Total Purchased for two specific products and cache the results for 15 minutes ( default is 12 hours )
[cd-purchased-total product_ids="16,19" cache_time="900"]
