如何让仅注册用户看到Woocommerce产品价格

add_filter(‘woocommerce_get_price_html’,’members_only_price’);
function members_only_price($price){
if(is_user_logged_in() ){
return $price;
}
else return ‘<a href="’ .get_permalink(woocommerce_get_page_id(‘myaccount’)). ‘">登录</a> 或 <a href="’.site_url(‘/wp-login.php?action=register&amp;redirect_to=’ . get_permalink()).’">注册</a>查看价格!';
}
