我正在重新创建一个多部分表单，但这个问题专门针对一个页面，其中有人注册可以标记他们可能拥有或增长的商品（如果有的话）。你可以在我的ASPX和ASPX.CS中看到我们迄今为止如何完成它（主要是利用类和一些ajax / javascript）。现在我们正在用PHP重新创建系统，我正在考虑更好（也许更简单是一个更好的词）方法来做到这一点。目前，商品列表是从SQL表中提取的，每个商品旁边都会显示一个下拉菜单（取决于它的测量单位 - EX：Acre，Flock，Head等）。在加入成员选择他的庄稼之后，他们将与他/她的成员ID和所述商品的数量一起致力于不同的桌子。见下文：
问题： 有什么，如果有的话，是用PHP做的更好的方法吗？
