您必须在函数中更改此项。php

if (!function_exists(\'my_commonPriceHtml\')) {

function my_commonPriceHtml($price_amt, $regular_price, $sale_price) {
    $html_price = \'<p class="price">\';
    //if product is in sale
    if (($price_amt == $sale_price) && ($sale_price != 0)) {
        $html_price .= \'<ins>\' . wc_price($sale_price) . \'</ins>\';
        $html_price .= \'&nbsp;&nbsp;<del>\' . wc_price($regular_price) . \'</del>\';
    }
    //in sale but free
    else if (($price_amt == $sale_price) && ($sale_price == 0)) {
        $html_price .= \'<ins>Free!</ins>\';
        $html_price .= \'<del>\' . wc_price($regular_price) . \'</del>\';

价格来自price.php woocommerce插件中的文件。在这个文件中有如下函数

$price_html = $product->get_price_html();

// Sale Price
<span class="price"><?php echo "Sale Price :". " " . get_woocommerce_currency_symbol().$product->get_sale_price(); ?></span>
// Regular Price
<span class="price"><?php echo "Regular Price :". " " . get_woocommerce_currency_symbol().$product->get_regular_price(); ?></span>
