用 Woocommerce 中的自定义文本标签替换零或空显示的价格

问题描述

我添加了这段代码，它适用于空的价格字段，但我也需要它适用于 0 的值.

I've added this code which works for empty price fields, but I also need it to work for values of 0.

add_filter('woocommerce_empty_price_html', 'custom_call_for_price');

function custom_call_for_price() {

    return 'Enquire';
}

推荐答案

这是针对空和零显示价格执行此操作的完整方法，因此此代码还替换您的实际代码(将被删除).

Here is the complete way to do it for BOTH empty and zero displayed prices, so this code replace also your actual code (to be removed).

它处理简单、可变和变化的显示价格(对于空和零显示价格):

It handle simple, variable and variation displayed prices (for BOTH empty and zero displayed prices):

// Variable and simple product displayed prices
add_filter( 'woocommerce_get_price_html', 'empty_and_zero_price_html', 20, 2 );
function empty_and_zero_price_html( $price, $product ) {
    $empty_price = __('Enquire', 'woocommerce');

    if( $product->is_type('variable') )
    {
        $prices = $product->get_variation_prices( true );

        if ( empty( $prices['price'] ) ) {
            return $empty_price; // <=== HERE below for empty price
        } else {
            $min_price     = current( $prices['price'] );
            $max_price     = end( $prices['price'] );
            if ( $min_price === $max_price && 0 == $min_price ) {
                return $empty_price; // <=== HERE for zero price
            }
            elseif ( $min_price !== $max_price && 0 == $min_price ) {
                return wc_price( $max_price );
            }
        }
    }
    elseif( $product->is_type('simple') )
    {
        if ( '' === $product->get_price() || 0 == $product->get_price() ) {
            return $empty_price; // <=== HERE for empty and zero prices
        }
    }
    return $price;
}

// Product Variation displayed prices
add_filter( 'woocommerce_available_variation', 'empty_and_zero_variation_prices_html', 10, 3);
function empty_and_zero_variation_prices_html( $data, $product, $variation ) {

    if( '' === $variation->get_price() || 0 == $variation->get_price() )
        $data['price_html'] = __('Enquire', 'woocommerce'); // <=== HERE for empty and zero prices

    return $data;
}

代码位于活动子主题(或活动主题)的 function.php 文件中.经测试有效.

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