Troubleshooting

Price history is not being recorded

Module is not active

Go to WPify → WPify Woo
Verify that the Prices log module is enabled
Save changes

Price has not changed

The module only records price changes. If the price is the same as the last recorded entry, a new entry will not be created.

Check:

// Last entry has the same price as the current one
$last = $repository->get_last_by_product_id( $product_id );
if (
    $last->regular_price === $product->get_regular_price()
    && $last->sale_price === $product->get_sale_price()
) {
    // New entry will not be created
}

Product was not saved

History is recorded when the product is saved. If you change the price directly in the database or via API without triggering woocommerce_update_product, the entry will not be created.

Lowest price is incorrect

Missing historical data

The module starts recording prices only after activation. Data from before activation does not exist.

Solution:

For existing products, edit and save the price to create the first entry
Or wait for a natural price change

Displays current price

If the product has no historical records from the last 30 days, the current price of the product will be displayed.

$price = $repository->find_lowest_price( $id ) ?: 0;
if ( ! $price ) {
    // Fallback to current price
    $price = wc_get_product( $id )->get_price();
}

”Prices log” tab is empty

New product

A new product does not have any entries yet. Entries will be created after the first price change.

Variable product

For variable products, entries are saved for each variation separately. The tab displays tables for each variation.

Database issues

Table does not exist

When the module is activated, a database table is automatically created. If the table is missing:

Deactivate the module
Reactivate the module
Check whether WordPress has permissions to create the table

Errors when saving

Check the WordPress error log:

wp-content/debug.log

Diagnostics

Checking product data

// In the product admin or debug plugin
$repository = wpify_woo_container()->get(
    \WpifyWoo\Modules\PricesLog\PricesLogRepository::class
);

$logs = $repository->find_by_product_id( $product_id );
echo '<pre>';
print_r( $logs );
echo '</pre>';

Checking lowest price

$prices_log = wpify_woo_container()->get(
    \WpifyWoo\Modules\PricesLog\PricesLogModule::class
);

$lowest = $prices_log->get_lowest_price( $product_id );
echo 'Lowest price: ' . wc_price( $lowest );

Performance

Large number of entries

For products with frequent price changes, the table may grow. The module does not include automatic cleanup of old entries.

Manual cleanup (optional):

-- Delete entries older than 90 days
DELETE FROM wp_wpify_woo_prices_log
WHERE created_at < DATE_SUB(NOW(), INTERVAL 90 DAY);
