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()
功能。我不需要用它做任何疯狂的事情,我真的只需要添加一个 HTML <span>
围绕价格属性。
我知道的代码如下:
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 );
}
我只想把它改成:
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 );
}
任何帮助都将不胜感激!谢谢!
最佳答案
添加自定义 html 标签 <span class="custom-prc">0000</span>
围绕价格,您需要在 formatted_woocommerce_price
中使用 Hook 函数 以这种方式过滤钩子(Hook):
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>';
}
代码位于您的事件子主题(或主题)的 function.php 文件中或任何插件文件中。
代码已经过测试并适用于 WooCommerce 3+
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>
" "
<span class="woocommerce-Price-currencySymbol">€</span>
</span>
</span>
