» main shop page
» product category pages
» product tag pages
↪ When to display minimal price (always or only when the product is on sale)
↪ How to count minimal price (the minimal from the moment product went on sale to 30 days before that moment or the minimal price from today to 30 days ago)
↪ How many days take into account when calculating minimal price (30 days by default)
↪ How to display the price history information
↪ What to do if the price didn’t change in the last N days (hide price information / display current price / display custom text)

At the configuration screen you will find additional information how to configure the plugin to be compliant with Omnibus directive (European Commission Directive 98/6/EC Article 6a) and link to legal acts.

How to configure plugin to be compliant with Omnibus directive

You don’t have to do anything special, the default settings are compliant with Omnibus directive!

However, in case you misconfigured the plugin, here are steps to take to make it compliant again (please note similar suggestions hints you will see on Settings screen):

  1. Go to WooCommerce > Price History screen
  2. Set Display on to Single product page
  3. Set Display minimal price to Only when product is on sale
  4. Set Count minimal price from to Day before product went on sale
  5. Set Number of days to use when counting minimal price: to 30 days
  6. For each product being on sale, go to its edit screen and set Sale price dates from to the date when the product went on sale.

Is plugin working well with variable products?

Yes, the plugin is compatible with product taxes and variable products (it tracks minimal price for each variation individually).

Is there any shortcode I could use to display minimal price?

If you want to display the lowest products price in other place than default, you can use shortcode wc_price_history. A few examples:

Display the lowest price on single product page (without passing product ID as argument), currency symbol attached:
This product low is [wc_price_history]

Display the lowest price of the other product, currency symbol attached:
The product with ID 3 had the lowest price [wc_price_history id=3]

Display without currency symbol:
The product with ID 3 had the lowest price [wc_price_history id=3 show_currency=0]

What filters and actions I can use to affect WC Price History internal logic?

Available filters are:
wc_price_history_is_correct_place (defined in PriorPrice\Prices::is_correct_place)
Allows to display price history on custom screens, not listed in plugins settings. Return true to make price history visible.

wc_price_history_is_not_correct_when (defined in `PriorPrice\Prices::is_not_correct_when`)

Allows to stop displaying price history for your own custom conditions. Return true to prevent displaying price history.

For some products being on sale, plugin shows minimal price from current day, why?

This is because you have not set Sale price dates from for these products. Go to the product edit screen and set Sale price dates from to the date when the product went on sale.

Tip: All the products which are On sale but does not have Sale price dates from set will be logged to WooCommerce logs. Go to WooCommerce > Status > Logs to see the list of products (in right top corner preselect log which name starts with wc-price-history).

Can I adjust minimal price before being it displayed?

Yes, you can use filter wc_price_history_lowest_price_html_raw_value_taxed:

`

add_filter( ‘wc_price_history_lowest_price_html_raw_value_taxed’, function( $price, $wc_product ) {
// do something with $price
return $price;
}, 10, 2 );
`

Can I clean the history?

Yes, on the plugin configuration screen click the button ‘Clean history’. This will remove all the history storage for all products. Make sure you know what you are doing (in general, use this option only if you are going to remove plugin completely).

I have a problem with the plugin, or I want to suggest a feature. Where can do this?

Please submit the GitHub issue.
