我想限制优惠券代码“XYZ”仅用于定义的工作日,仅限周一至周四.其他日子(星期五到星期日)会显示错误通知.
可能吗?我怎样才能做到这一点?
谢谢
解决方法:
这是一个完整的解决方案,包含2个挂钩功能,可以限制您定义的工作日的优惠券使用情况,如果优惠券无效,则会显示自定义错误通知.
1)检查“定义天数”优惠券有效期:
add_filter( 'woocommerce_coupon_is_valid', 'coupon_week_days_check', 10, 2);
function coupon_week_days_check( $valid, $coupon ) {
// Set HERE your coupon slug <=== <=== <=== <=== <=== <=== <=== <=== <=== <===
$coupon_code_wd = 'xyz';
// Set HERE your defined invalid days (others: 'Mon', 'Tue', 'Wed' and 'Thu') <=== <===
$invalid_days = array('Fri', 'Sat', 'Sun');
$now_day = date ( 'D' ); // Now day in short format
// WooCommerce version compatibility
if ( version_compare( WC_VERSION, '3.0', '<' ) ) {
$coupon_code = strtolower($coupon->code); // Older than 3.0
} else {
$coupon_code = strtolower($coupon->get_code()); // 3.0+
}
// When 'xyz' is set and if is not a week day we remove coupon and we display a notice
if( $coupon_code_wd == $coupon_code && in_array($now_day, $invalid_days) ){
// if not a week day
$valid = false;
}
return $valid;
}
2)如果无效,则显示“已定义天数”优惠券的自定义错误消息:
add_filter('woocommerce_coupon_error', 'coupon_week_days_error_message', 10, 3);
function coupon_week_days_error_message( $err, $err_code, $coupon ) {
// Set HERE your coupon slug <=== <=== <=== <=== <=== <=== <=== <=== <=== <===
$coupon_code_wd = 'xyz';
// Set HERE your defined invalid days (others: 'Mon', 'Tue', 'Wed' and 'Thu') <=== <===
$invalid_days = array('Fri', 'Sat', 'Sun');
$now_day = date ( 'D' ); // Now day in short format
// WooCommerce version compatibility
if ( version_compare( WC_VERSION, '3.0', '<' ) ) {
$coupon_code = strtolower($coupon->code); // Older than 3.0
} else {
$coupon_code = strtolower($coupon->get_code()); // 3.0+
}
if( $coupon_code_wd == $coupon_code && intval($err_code) === WC_COUPON::E_WC_COUPON_INVALID_FILTERED && in_array($now_day, $invalid_days) ) {
$err = __( "Coupon $coupon_code_wd only works on weekdays and has been removed", "woocommerce" );
}
return $err;
}
代码放在活动子主题(或主题)的function.php文件中,或者放在任何插件文件中.
此工作代码在WooCommerce版本2.6.x和3.0上进行了测试.
