WooCommerce 教程：显示％折扣在 Shop＆Loop页面

如果该项目正在出售，默认的 WooCommerce 会显示 “销售” 徽章，但是如何显示确切的销售百分比呢？

我为自己的一位客户实现了这一点，所以在这里您可以轻松地解决问题！

WooCommerce 3.0+ PHP 代码片段：显示折扣百分比 @循环页面 – WooCommerce

/**
 * @snippet       Display Discount Percentage @ Loop Pages - WooCommerce

 * @sourcecode    https://businessbloomer.com/?p=21997
 * @author        Rodolfo Melogli
 * @compatible    WC 3.1.0
 */

add_action( 'woocommerce_before_shop_loop_item_title', 'bbloomer_show_sale_percentage_loop', 25 );

function bbloomer_show_sale_percentage_loop() {

global $product;

if ( $product->is_on_sale() ) {

if ( ! $product->is_type( 'variable' ) ) {

$max_percentage = ( ( $product->get_regular_price() - $product->get_sale_price() ) / $product->get_regular_price() ) * 100;

} else {

$max_percentage = 0;

foreach ( $product->get_children() as $child_id ) {
	$variation = wc_get_product( $child_id );
	$price = $variation->get_regular_price();
	$sale = $variation->get_sale_price();
	if ( $price != 0 && ! empty( $sale ) ) $percentage = ( $price - $sale ) / $price * 100;
	if ( $percentage > $max_percentage ) {
		$max_percentage = $percentage;
	}
}

}

echo "<div class='sale-perc'>-" . round($max_percentage) . "%</div>";

}

}

add_action( 'woocommerce_before_shop_loop_item_title', 'bbloomer_show_sale_percentage_loop', 25 );

function bbloomer_show_sale_percentage_loop() {
global $product;
if ( $product->is_on_sale() ) {
if ( ! $product->is_type( 'variable' ) ) {
$max_percentage = round( ( ( $product->regular_price - $product->sale_price ) / $product->regular_price ) * 100 );
} else {
foreach ( $product->get_children() as $child_id ) :
$variation = $product->get_child( $child_id );
$price = $variation->get_regular_price();
$sale = $variation->get_sale_price();
$percentage = $price != 0 && ! empty( $sale ) ? ( ( $price - $sale ) / $price * 100 ) : $max_percentage;
if ( $percentage >= $highest_percentage ) :
	$max_percentage = $percentage;
	$regular_price = $product->get_variation_regular_price( 'min' );
	$sale_price = $product->get_variation_sale_price( 'min' );
endif;
endforeach;
}
echo "<div class='sale-perc'>-" . round($max_percentage) . "%</div>";
}
}

还有一点 CSS：

.sale-perc {
background-color: #D9534F;
display: inline;
padding: .2em .6em .3em;
font-size: 75%;
font-weight: bold;
color: #fff;
text-align: center;
border-radius: .25em;
}
