您的代码有点过时,因为 woocommerce 版本 3 作为 Product 对象属性无法直接访问。相反,您应该使用可用的WC_Product 方法。
要格式化价格,您将使用wc_price() 专用格式化功能。
现在你可以拥有(3种可能性):
1) 节省的价格:
add_filter( 'woocommerce_get_price_html', 'change_displayed_sale_price_html', 10, 2 );
function change_displayed_sale_price_html( $price, $product ) {
// Only on sale products on frontend and excluding min/max price on variable products
if( $product->is_on_sale() && ! is_admin() && ! $product->is_type('variable')){
// Get product prices
$regular_price = (float) $product->get_regular_price(); // Regular price
$sale_price = (float) $product->get_price(); // Active price (the "Sale price" when on-sale)
// "Saving price" calculation and formatting
$saving_price = wc_price( $regular_price - $sale_price );
// Append to the formated html price
$price .= sprintf( __('<p class="saved-sale">Save: %s</p>', 'woocommerce' ), $saving_price );
}
return $price;
}
2) 节省百分比:
add_filter( 'woocommerce_get_price_html', 'change_displayed_sale_price_html', 10, 2 );
function change_displayed_sale_price_html( $price, $product ) {
// Only on sale products on frontend and excluding min/max price on variable products
if( $product->is_on_sale() && ! is_admin() && ! $product->is_type('variable')){
// Get product prices
$regular_price = (float) $product->get_regular_price(); // Regular price
$sale_price = (float) $product->get_price(); // Active price (the "Sale price" when on-sale)
// "Saving Percentage" calculation and formatting
$precision = 1; // Max number of decimals
$saving_percentage = round( 100 - ( $sale_price / $regular_price * 100 ), 1 ) . '%';
// Append to the formated html price
$price .= sprintf( __('<p class="saved-sale">Save: %s</p>', 'woocommerce' ), $saving_percentage );
}
return $price;
}
3 两者都(折扣价和百分比):
add_filter( 'woocommerce_get_price_html', 'change_displayed_sale_price_html', 10, 2 );
function change_displayed_sale_price_html( $price, $product ) {
// Only on sale products on frontend and excluding min/max price on variable products
if( $product->is_on_sale() && ! is_admin() && ! $product->is_type('variable')){
// Get product prices
$regular_price = (float) $product->get_regular_price(); // Regular price
$sale_price = (float) $product->get_price(); // Active price (the "Sale price" when on-sale)
// "Saving price" calculation and formatting
$saving_price = wc_price( $regular_price - $sale_price );
// "Saving Percentage" calculation and formatting
$precision = 1; // Max number of decimals
$saving_percentage = round( 100 - ( $sale_price / $regular_price * 100 ), 1 ) . '%';
// Append to the formated html price
$price .= sprintf( __('<p class="saved-sale">Save: %s <em>(%s)</em></p>', 'woocommerce' ), $saving_price, $saving_percentage );
}
return $price;
}
代码进入您的活动子主题(或活动主题)的 function.php 文件中。
经过测试并且有效。
