显示 Woocommerce 变量产品中后缀的选定变体价格

Question

I am using this function so I get the default variation price but I want to show my price suffix after the price:

add_filter('woocommerce_variable_price_html', 'custom_variation_price', 10, 2);
function custom_variation_price( $price, $product ) {
    foreach($product->get_available_variations() as $pav){
        $def=true;
        foreach($product->get_variation_default_attributes() as $defkey=>$defval){
            if($pav['attributes']['attribute_'.$defkey]!=$defval){
                $def=false;             
            }   
        }
        if($def){
            $price = $pav['display_price'];         
        }
    }   
    return woocommerce_price($price);
}

What I am getting out now is for example '€15,00' but what I want it to show is '€15,00 per kilo' and 'per kilo' is the price suffix

Your code is outdated since Woocommerce 3 ( get_variation_default_attributes() and woocommerce_price() are deprecated) .

The will display the selected variation price suffixed for Woocommerce 3:

add_filter('woocommerce_available_variation', 'display_variation_price_suffixed', 10, 3 );
function display_variation_price_suffixed( $variation_data, $product, $variation ) {
    $variation_data['price_html'] .= ' <span class="price-suffix">' . __("per kilo", "woocommerce") . '</span>';

    return $variation_data;
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

If needed you can use $variation_data['attributes'] array to target specific product attributes term values in a foreach loop.

For information, the filter hook woocommerce_available_variation is located inside WC_Product_Variable get_available_variation() method.
