woocommerce_variation_prices_price │ filter-hook │ WC 3.0.0

Filters the active price for a product variation before it is used in price calculations and caching.

IMPORTANT: If your filter returns a price that varies by ANY factor (e.g., current user, time of day, user role, cart contents, etc.), you MUST also hook into the woocommerce_get_variation_prices_hash to include that factor in the cache key. Otherwise, the wrong price may be cached and displayed to different users or contexts.

Example: Applying a per-user discount and adapting the price hash info accordingly:

class My_Custom_Pricing {

public function __construct() {
	add_filter( 'woocommerce_variation_prices_price', array( $this, 'apply_user_discount' ), 10, 3 );
	add_filter( 'woocommerce_get_variation_prices_hash', array( $this, 'add_user_to_hash' ), 10, 3 );
}

public function apply_user_discount( $price, $variation, $product ) {
	return $price * $this->get_discount_for_user( get_current_user_id() );
}

public function add_user_to_hash( $price_hash, $product, $for_display ) {
	$price_hash[] = get_current_user_id();
	return $price_hash;
}

}

add_filter( 'woocommerce_variation_prices_price', 'wp_kama_woocommerce_variation_prices_price_filter', 10, 3 );
