当我将此代码添加到functions.php时 我收到内部服务器错误.... 怎么了?
该片段的用途:此代码用于替换具有变化(价格1,价格2)的产品中的价格,它将从“1 $”输出,显示价格较低......
在debbuging从日志中得到了这个:
PHP Warning: Cannot modify header information - headers already sent by (output started at /home/organicb/public_html/wp-content/themes/flatsome-child/functions.php:20) in /home/organicb/public_html/wp-includes/pluggable.php
在https://gist.github.com/kloon/8981075 中找到了代码段
// Use WC 2.0 variable price format, now include sale price strikeout
add_filter( 'woocommerce_variable_sale_price_html', 'wc_wc20_variation_price_format', 10, 2 );
add_filter( 'woocommerce_variable_price_html', 'wc_wc20_variation_price_format', 10, 2 );
function wc_wc20_variation_price_format( $price, $product ) {
// Main Price
$prices
= array( $product->get_variation_price( 'min', true ), $product->get_variation_price( 'max', true ) );
$price = $prices[0] !== $prices[1] ? sprintf( __( 'Desde: %1$s', 'woocommerce' ), wc_price( $prices[0] ) ) : wc_price( $prices[0] );
// Sale Price
$prices = array( $product->get_variation_regular_price( 'min', true ), $product->get_variation_regular_price( 'max', true ) );
sort( $prices );
$saleprice = $prices[0] !== $prices[1] ? sprintf( __( 'Desde: %1$s', 'woocommerce' ), wc_price( $prices[0] ) ) : wc_price( $prices[0] );
if ( $price !== $saleprice ) {
$price = '<del>' . $saleprice . '</del> <ins>' . $price . '</ins>';
}
return $price;}

您应该使用wp_debug启用。在您的wp-config.php文件中,搜索:
define('WP_DEBUG', false);
并改为:
define('WP_DEBUG', true);
