I had this code in function.php of my theme to display the percentage after price and it was working fine in WooCommerce v2.6.14.
But this snippet doesn't work anymore on WooCommerce version 3.0+.
How can I fix that?
Here is that code:
// Add save percent next to sale item prices.
add_filter( 'woocommerce_sale_price_html', 'woocommerce_custom_sales_price', 10, 2 );
function woocommerce_custom_sales_price( $price, $product ) {
$percentage = round( ( ( $product->regular_price - $product->sale_price ) / $product->regular_price ) * 100 );
return $price . sprintf( __(' Save %s', 'woocommerce' ), $percentage . '%' );
}
Updated - 2019 (avoid rounding price issue) - 2017 (avoid
NAN%percentage value)
woocommerce_sale_price_html hook has been replaced by a different hook in WooCommerce 3.0+, that has now 3 arguments (but not the $product argument anymore).
add_filter( 'woocommerce_format_sale_price', 'woocommerce_custom_sales_price', 10, 3 );
function woocommerce_custom_sales_price( $price, $regular_price, $sale_price ) {
// Getting the clean numeric prices (without html and currency)
$_reg_price = floatval( strip_tags($regular_price) );
$_sale_price = floatval( strip_tags($sale_price) );
// Percentage calculation and text
$percentage = round( ( $_reg_price - $_sale_price ) / $_reg_price * 100 ).'%';
$percentage_txt = ' ' . __(' Save ', 'woocommerce' ) . $percentage;
$formatted_regular_price = is_numeric( $regular_price ) ? wc_price( $regular_price ) : $regular_price;
$formatted_sale_price = is_numeric( $sale_price ) ? wc_price( $sale_price ) : $sale_price;
echo '<del>' . $formatted_regular_price . '</del> <ins>' . $formatted_sale_price . $percentage_txt . '</ins>';
}
This code goes in function.php file of your active child theme (or theme) or also in any plugin file.
The code is tested and works. For WooCommerce version 3.0+ (thanks to @Mikebcn and @AsifRao)
For rounding the percentage you can use round(), number_format() or number_format_i18n():
$percentage = number_format_i18n( ( $_reg_price - $_sale_price ) / $_reg_price * 100, 0 ).'%';
$percentage = number_format( ( $_reg_price - $_sale_price ) / $_reg_price * 100, 0 ).'%';
Original answer code: Here is that functional similar code:
// Only for WooCommerce version 3.0+
add_filter( 'woocommerce_format_sale_price', 'woocommerce_custom_sales_price', 10, 3 );
function woocommerce_custom_sales_price( $price, $regular_price, $sale_price ) {
$percentage = round( ( $regular_price - $sale_price ) / $regular_price * 100 ).'%';
$percentage_txt = ' ' . __(' Save ', 'woocommerce' ) . $percentage;
$price = '<del>' . ( is_numeric( $regular_price ) ? wc_price( $regular_price ) : $regular_price ) . '</del> <ins>' . ( is_numeric( $sale_price ) ? wc_price( $sale_price ) . $percentage_txt : $sale_price . $percentage_txt ) . '</ins>';
return $price;
}
