在 WooCommerce 中的一周中的特定日期为某些送货区域提供免费送货服务
Make free shipping available for certain shipping zones on specific days of the week in WooCommerce
我正在尝试在选定的日期为特定的送货区域(数组)启用免费送货。
因此我正在使用此代码:
add_filter( 'woocommerce_shipping_free_shipping_is_available', 'enable_free_shipping_on_selected_days', 10, 3 );
function enable_free_shipping_on_selected_days( $is_available, $package, $shipping_method ) {
$shipping_zones = array('US, Europe');
if ( array_key_exists( $shipping_zones, $rates ) && in_array( date( 'w' ), [ 6, 7 ] ) ) {
return true;
}
return $is_available;
}
但我收到一个错误:“未捕获的类型错误:array_key_exists():参数 #2 ($array) 必须是数组类型,null given in..”
关于如何在一周中的特定日期为某些送货区域提供免费送货的任何建议?
$rates
未在您的代码中设置,因此出现错误消息
要根据送货区域和一周中的特定日期提供免费送货服务,您可以使用:
function filter_woocommerce_shipping_free_shipping_is_available( $available, $package, $shipping_method ) {
// The targeted shipping zones. Multiple can be entered, separated by a comma
$shipping_zones = array( 'US', 'Europe', 'België' );
// The targeted day numbers. 0 = Sunday, 1 = Monday.. to 6 for Saturday. Multiple can be entered, separated by a comma
$day_numbers = array( 0, 1, 6 );
// Message
$notice = __( 'free shipping available', 'woocommerce' );
/* END settings */
// Default
$available = false;
// Get shipping zone
$shipping_zone = wc_get_shipping_zone( $package );
// Get the zone name
$zone_name = $shipping_zone->get_zone_name();
// Checks if a value exists in an array (zone name)
if ( in_array( $zone_name, $shipping_zones ) ) {
// Set the default timezone to use.
date_default_timezone_set( 'UTC' );
// Day number
$day_number = date( 'w' );
// Checks if a value exists in an array (day number)
if ( in_array( $day_number, $day_numbers ) ) {
// Clear all other notices
wc_clear_notices();
// Display notice
wc_add_notice( $notice, 'notice' );
// True
$available = true;
}
}
// Return
return $available;
}
add_filter( 'woocommerce_shipping_free_shipping_is_available', 'filter_woocommerce_shipping_free_shipping_is_available', 10, 3 );
// Optional: Hide other shipping methods when free shipping is available
function filter_woocommerce_package_rates( $rates, $package ) {
// Empty array
$free = array();
// Loop trough
foreach ( $rates as $rate_id => $rate ) {
if ( $rate->method_id === 'free_shipping' ) {
$free[ $rate_id ] = $rate;
// Break loop
break;
}
}
return ! empty( $free ) ? $free : $rates;
}
add_filter( 'woocommerce_package_rates', 'filter_woocommerce_package_rates', 10, 2 );
