The display of the lowest price in the last 30 days is not the same in the langu

Hi,

Could you let me know how the product is translated? Is it just the text, or are there separate product versions for Croatian and English? If there are two versions, please check the recorded prices for each language. To do this, edit the product, go to the Product Price History tab, and verify how many recorded prices are listed and if they match.

Also, could you confirm if you’re using the free version or the Pro version of the plugin?

I have reproduced the issue and can confirm that WPML does not copy price history data. Instead, it only syncs the current prices, which causes our Lowest Price to display based on the available info—the regular price.

We will work on improving compatibility with WPML in future updates. In the meantime, I’ve created a PHP snippet that will “sync” the price history for translated products.

You can add the following code to your child theme’s functions.php file or use a plugin like Code Snippets to apply it safely. Avoid adding it directly to your parent theme’s functions.php, as updates will overwrite it.

add_filter('pph_lowest_price', function ($lowest_price, $product_id, $product) {

    // Check if WPML functions exist before calling them
    if (!function_exists('wpml_get_default_language')) {
        return $lowest_price;
    }

    $default_language = wpml_get_default_language();
    if (!$default_language) {
        return $lowest_price;
    }

    $original_product_id = apply_filters('wpml_object_id', $product_id, 'product', true, $default_language);

    if (
        $original_product_id &&
        $original_product_id != $product_id &&
        class_exists('\Devnet\PPH\Modules\LowestPrice\Helper') &&
        method_exists('\Devnet\PPH\Modules\LowestPrice\Helper', 'get_lowest_price')
    ) {
        // Fetch original product
        $original_product = wc_get_product($original_product_id);
        // Get the lowest price from the master product
        $lowest_price = \Devnet\PPH\Modules\LowestPrice\Helper::get_lowest_price($original_product_id, $original_product);
    }

    return $lowest_price;
}, 10, 3);

Let me know if you need any help applying it!

Glad to hear everything is working now!

Regarding the Delete price history older than option: currently, it is a manual action, meaning you need to select the timeframe (e.g., previous 30 days) and confirm the deletion. There is no automatic deletion feature at the moment.

In most cases, deleting price history is not recommended, as it helps maintain accurate pricing records for compliance and transparency. However, it can be useful in two scenarios:

1. After development and testing—when you’re preparing a new site to go live.
2. On sites with frequent price changes—if older data becomes irrelevant due to frequent daily updates.

You can delete the price history records, or alternatively, you can hide them individually inside the Price History table on the edit product page.

The regular price will only be displayed as the lowest price if the option is enabled and there are no price history records at all. However, keep in mind that this is not in line with EU regulations. According to the law, the lowest price should be the lowest recorded price in the 30 days before the sale started.

To clarify, under the EU Consumer Protection Act, the lowest price must be the lowest recorded price in the 30 days before a sale begins. This is meant to prevent misleading discounting practices.

For example:

• A product is regularly priced at €200.
• On January 1st, you offer a discount to €150.
• In the 30 days before that (December 1-31), there might have been multiple price changes or none at all. What matters is the lowest price at which the product was actually sold during that period. So if the lowest recorded selling price was €140, then €140 must be displayed as the lowest price during the sale.
• If the product remains at €150 for more than 30 days (e.g., until March), then for any future discounts, the new lowest price will be €150 if there was no lower price in the preceding 30 days.

Great! I’m glad that I was able to help you. 🙂 If you find the plugin handy and feel like sharing your thoughts, leaving a review would be awesome. Your input is truly appreciated!
