Question

我创建了一个简单的引荐系统，当您创建帐户时，它会创建引荐链接，您可以将其发送给个人，以便他们在使用该链接进行注册时使用。在用户表上，输入referred_id以匹配发送链接的用户ID。

http://localhost:8000/register/?ref=12

我遇到的唯一问题是，当我推荐用户时，cookie会保存好，但是如果我不使用www.localhost/8000/register来推荐用户而仅推荐用户的cookie，仍然会在其中输入用户表。但是用户表上的referred_id应该为空，因为我没有使用引荐链接？我该如何解决这个问题

如果您要执行此行为，则应仅使用查询参数，而不要使用Cookie；如果您在此处使用Cookie，即

  //nav-active
  function onScroll(event){
    var scrollPosition = $(document).scrollTop();
    $('.menu-list a').each(function () {
      var currentLink = $(this);
      var linkHref = currentLink.attr("href"); // extract the href attribute from link
      var anchor = linkHref.split("#").pop(); // split by # and take the last part
      var refElement = $("#" + anchor); // use the anchor extract to use it as id selector

      // add refElement.length check - to just continue if the element actually exist
      if (refElement.length && refElement.position().top <= scrollPosition && refElement.position().top + refElement.height() > scrollPosition) {
        $('.menu-list a').removeClass("active");
        currentLink.addClass("active");
      }
      else{
        currentLink.removeClass("active");
      }
    });
  }

如果存在，它将从cookie中获取价值。如果您只想在提交查询参数（如

）时保存$ referred_by

$referred_by = Cookie::get('referral');

您应该使用

http://localhost:8000/register/?ref=12
