WooCommerce购物车及结账页移除配送标签仅留金额问题求助

问题说明 #

需要在WooCommerce购物车和结账页面实现：当配送金额完成赋值后，移除配送标签文本，仅保留金额（例如将“flat rate 100.00$”改为“100.00$”）。目前已通过shipping_package_rates_filter_callback函数设置$rates[$targeted_rate_id]->label = '';，但金额前仍会显示多余的冒号（如:100.00$）。

原函数代码如下：

add_filter( 'woocommerce_package_rates', 'shipping_package_rates_filter_callback', 100, 2 );
function shipping_package_rates_filter_callback( $rates, $package ) {
    // HERE define your targeted rate id
    $targeted_rate_id = 'flat_rate:4'; 
    
    if ( ! array_key_exists($targeted_rate_id, $rates) ) 
        return $rates;
    
    $new_cost = WC()->session->get('shipping_cost'); // Get new cost from WC sessions

    if ( ! empty($new_cost) ) {
        // Set shipping label empty
        $rates[$targeted_rate_id]->label = '';
        $rate = $rates[$targeted_rate_id];
        $cost = $rate->cost; // Set the initial cost in a variable for taxes calculations
        $rates[$targeted_rate_id]->cost = $new_cost; // Set the new cost

        $has_taxes = false; // Initializing
        $taxes     = array(); // Initializing
        foreach ($rate->taxes as $key => $tax_cost){
            if( $tax_cost > 0 ) {
                $tax_rate    = $tax_cost / $cost; // Get the tax rate conversion
                $taxes[$key] = $new_cost * $tax_rate; // Set the new tax cost in taxes costs array
                $has_taxes   = true; // There are taxes (set it to true)
            }
        }
        if( $has_taxes ) {
            $rates[$targeted_rate_id]->taxes = $taxes; // Set taxes costs array
        }
    } else {
        unset($rates[$targeted_rate_id]);
    }
    return $rates;
}

解决方案 #

出现冒号的原因是WooCommerce默认模板会在配送标签和金额之间固定输出冒号，即使标签为空也会保留。可以通过添加woocommerce_cart_shipping_method_full_label过滤器，直接修改完整的配送显示文本，跳过冒号的输出。

修改后的完整代码 #

add_filter( 'woocommerce_package_rates', 'shipping_package_rates_filter_callback', 100, 2 );
function shipping_package_rates_filter_callback( $rates, $package ) {
    // HERE define your targeted rate id
    $targeted_rate_id = 'flat_rate:4'; 
    
    if ( ! array_key_exists($targeted_rate_id, $rates) ) 
        return $rates;
    
    $new_cost = WC()->session->get('shipping_cost'); // Get new cost from WC sessions

    if ( ! empty($new_cost) ) {
        // Set shipping label empty
        $rates[$targeted_rate_id]->label = '';
        $rate = $rates[$targeted_rate_id];
        $cost = $rate->cost; // Set the initial cost in a variable for taxes calculations
        $rates[$targeted_rate_id]->cost = $new_cost; // Set the new cost

        $has_taxes = false; // Initializing
        $taxes     = array(); // Initializing
        foreach ($rate->taxes as $key => $tax_cost){
            if( $tax_cost > 0 ) {
                $tax_rate    = $tax_cost / $cost; // Get the tax rate conversion
                $taxes[$key] = $new_cost * $tax_rate; // Set the new tax cost in taxes costs array
                $has_taxes   = true; // There are taxes (set it to true)
            }
        }
        if( $has_taxes ) {
            $rates[$targeted_rate_id]->taxes = $taxes; // Set taxes costs array
        }
    } else {
        unset($rates[$targeted_rate_id]);
    }
    return $rates;
}

// 移除配送金额前的冒号，仅显示金额
add_filter( 'woocommerce_cart_shipping_method_full_label', 'remove_shipping_label_colon', 100, 2 );
function remove_shipping_label_colon( $label, $method ) {
    $targeted_rate_id = 'flat_rate:4';
    
    // 匹配目标配送方式，且标签为空时，直接返回格式化后的金额
    if ( $method->id === $targeted_rate_id && empty($method->label) ) {
        return wc_price( $method->cost + array_sum( $method->taxes ) );
    }
    
    return $label;
}

代码说明 #

1. 保留原有的shipping_package_rates_filter_callback函数，负责设置配送金额和清空标签
2. 添加remove_shipping_label_colon回调函数，通过woocommerce_cart_shipping_method_full_label过滤器拦截完整的配送显示文本：
   • 判断当前配送方式是否为目标ID，且标签为空
   • 直接返回包含税费的格式化金额，跳过默认的“标签: 金额”结构
3. 优先级设为100，确保覆盖WooCommerce的默认输出逻辑
