正确覆盖预先存在的WooCommerce功能的最佳方法是什么?在这种情况下,我想修改wc_price()函数。我不需要做任何疯狂的事情,我只需在价格附近添加HTML <span>属性。

我知道代码如下:

function wc_price( $price, $args = array() ) {
    extract( apply_filters( 'wc_price_args', wp_parse_args( $args, array(
      'ex_tax_label'       => false,
      'currency'           => '',
      'decimal_separator'  => wc_get_price_decimal_separator(),
      'thousand_separator' => wc_get_price_thousand_separator(),
      'decimals'           => wc_get_price_decimals(),
      'price_format'       => get_woocommerce_price_format(),
    ) ) ) );

    $negative        = $price < 0;
    $price           = apply_filters( 'raw_woocommerce_price', floatval( $negative ? $price * -1 : $price ) );
    $price           = apply_filters( 'formatted_woocommerce_price', number_format( $price, $decimals, $decimal_separator, $thousand_separator ), $price, $decimals, $decimal_separator, $thousand_separator );

    if ( apply_filters( 'woocommerce_price_trim_zeros', false ) && $decimals > 0 ) {
       $price = wc_trim_zeros( $price );
    }

    $formatted_price = ( $negative ? '-' : '' ) . sprintf( $price_format, '<span class="woocommerce-Price-currencySymbol">' . get_woocommerce_currency_symbol( $currency ) . '</span>', $price );
    $return          = '<span class="woocommerce-Price-amount amount">' . $formatted_price . '</span>';

    if ( $ex_tax_label && wc_tax_enabled() ) {
       $return .= ' <small class="woocommerce-Price-taxLabel tax_label">' . WC()->countries->ex_tax_or_vat() . '</small>';
    }

    return apply_filters( 'wc_price', $return, $price, $args );
}

我想做的就是将其改为:

function wc_price( $price, $args = array() ) {
    extract( apply_filters( 'wc_price_args', wp_parse_args( $args, array(
      'ex_tax_label'       => false,
      'currency'           => '',
      'decimal_separator'  => wc_get_price_decimal_separator(),
      'thousand_separator' => wc_get_price_thousand_separator(),
      'decimals'           => wc_get_price_decimals(),
      'price_format'       => get_woocommerce_price_format(),
    ) ) ) );

    $negative        = $price < 0;
    $price           = apply_filters( 'raw_woocommerce_price', floatval( $negative ? $price * -1 : $price ) );
    $price           = apply_filters( 'formatted_woocommerce_price', number_format( $price, $decimals, $decimal_separator, $thousand_separator ), $price, $decimals, $decimal_separator, $thousand_separator );

    if ( apply_filters( 'woocommerce_price_trim_zeros', false ) && $decimals > 0 ) {
       $price = wc_trim_zeros( $price );
    }

    $formatted_price = ( $negative ? '-' : '' ) . sprintf( $price_format, '<span class="woocommerce-Price-currencySymbol">' . get_woocommerce_currency_symbol( $currency ) . '</span>', <span class="custom-prc"> . $price . </span> );
    $return          = '<span class="woocommerce-Price-amount amount">' . $formatted_price . '</span>';

    if ( $ex_tax_label && wc_tax_enabled() ) {
       $return .= ' <small class="woocommerce-Price-taxLabel tax_label">' . WC()->countries->ex_tax_or_vat() . '</small>';
    }

    return apply_filters( 'wc_price', $return, $price, $args );
}

任何帮助都将非常感谢!谢谢!

要在价格附近添加自定义html代码<span class="custom-prc">0000</span>,您需要在 formatted_woocommerce_price 过滤器钩子中使用钩子函数:

add_filter( 'formatted_woocommerce_price', 'span_custom_prc', 10, 5 );
function span_custom_prc( $number_format, $price, $decimals, $decimal_separator, $thousand_separator){
    return '<span class="custom-prc">'.$number_format.'</span>';
}

代码放在活动子主题(或主题)的function.php文件中,或者放在任何插件文件中。

代码已经过测试,可以与WooCommerce 3 +一起使用

然后你会得到这个html输出(例如 42,00 euros ):

<span class="price">
    <span class="woocommerce-Price-amount amount">
        <span class="custom-prc">42,03</span>
        "&nbsp;"
        <span class="woocommerce-Price-currencySymbol">€</span>
    </span>
</span>
