WooCommerce 教程：当有免费送货时隐藏其他送货选项

如果您想要为特定国家/地区仅显示一种运送方式，则需要一些额外的编码。在此示例中，我们将禁用所有运送方式，但 “免费送货” 。这里是添加到您的 functions.php 的 PHP 代码

代码段＃1：在 1 个运送区域中取消设置 1 个免费版本

要找到新的 “运送方式名称”，例如 “ free_shipping：8 ”

/**
 * @snippet       Hide one shipping option in one zone when Free Shipping is available

 * @sourcecode    https://businessbloomer.com/?p=260
 * @author        Rodolfo Melogli
 * @compatible    WooCommerce 3.1.1
 */

add_filter( 'woocommerce_package_rates', 'bbloomer_unset_shipping_when_free_is_available_in_zone', 10, 2 );
 
function bbloomer_unset_shipping_when_free_is_available_in_zone( $rates, $package ) {
 	
 	// Only unset rates if free_shipping is available
  	if ( isset( $rates['free_shipping:8'] ) ) {
  	unset( $rates['flat_rate:1'] );
}  	
	
return $rates;

}

代码段＃1：在可用空闲时，在所有区域中取消设置所有费率

/**
 * @snippet       Hide ALL shipping rates in ALL zones when Free Shipping is available

 * @sourcecode    https://businessbloomer.com/?p=260
 * @author        Rodolfo Melogli
 * @compatible    WooCommerce 3.1.1
 */

add_filter( 'woocommerce_package_rates', 'bbloomer_unset_shipping_when_free_is_available_all_zones', 10, 2 );
 
function bbloomer_unset_shipping_when_free_is_available_all_zones( $rates, $package ) {
 	
 	$all_free_rates = array();
	
        foreach ( $rates as $rate_id => $rate ) {
		if ( 'free_shipping' === $rate->method_id ) {
			$all_free_rates[ $rate_id ] = $rate;
			break;
		}
	}
	
	if ( empty( $all_free_rates )) {
        return $rates;
        } else {
        return $all_free_rates;
        } 
}

对于旧版本的 WooCommerce [2.1-2.5]（当 Free 可用时，取消设置一个速率）

/**
 * @snippet       Hide one shipping option when Free Shipping is available

 * @sourcecode    https://businessbloomer.com/?p=260
 * @author        Rodolfo Melogli
 * @compatible    WooCommerce 2.4.10
 */

add_filter( 'woocommerce_package_rates', 'bbloomer_unset_shipping_when_free_is_available', 10, 2 );
 
function bbloomer_unset_shipping_when_free_is_available( $rates, $package ) {
 	
 	// Only unset rates if free_shipping is available
  	if ( isset( $rates['free_shipping'] ) ) {
  		unset( $rates['flat_rate'] );
  		return $rates;
}

}

对于旧版本的 WooCommerce [2.1-2.5]（免费提供时，设置所有费率）

/**
 * @snippet       Hide ALL shipping options when Free Shipping is available

 * @sourcecode    https://businessbloomer.com/?p=260
 * @author        Rodolfo Melogli
 * @compatible    WooCommerce 2.4.10
 */

add_filter( 'woocommerce_package_rates', 'bbloomer_unset_shipping_when_free_is_available', 10, 2 );
 
function bbloomer_unset_shipping_when_free_is_available( $rates, $package ) {
 	
 	// Only unset rates if free_shipping is available
  	if ( isset( $rates['free_shipping'] ) ) {
  	
  	$free_shipping = $rates['free_shipping'];
	$rates = array();
	$rates['free_shipping'] = $free_shipping;
	}
	
	return $rates;
}

请注意：如果您无法使其工作，您必须清除 WooCommerce 缓存（WooCommerce> 系统状态）。见下图。

达到 WooCommerce 2.1

// Hide standard shipping option when free shipping is available
add_filter( 'woocommerce_available_shipping_methods', 'hide_standard_shipping_when_free_is_available' , 10, 1 );
 
/**
 *  Hide Standard Shipping option when free shipping is available
 * 
 * @param array $available_methods
 */
function hide_standard_shipping_when_free_is_available( $available_methods ) {
 
    if( isset( $available_methods['free_shipping'] ) AND isset( $available_methods['flat_rate'] ) ) {
 
        // remove standard shipping option
        unset( $available_methods['flat_rate'] );
    }
 
    return $available_methods;
}
