我希望我能解释一下让所有人理解。我创建了一个搜索功能表单，包含两个多选项和复选框。一个多选择具有性别，第二个具有从1900年到当年的年份，并且复选框具有一些代码和一些剂量的预定。搜索功能有效但我被要求稍微更改一下。我想要做的是，如果用户选择两个处方，例如我想要获得具有两个处方的行，而只选择已经选择的两个处方。目前我已经循环遍历复选框数组的循环，并且如果它具有与该搜索项匹配的任何处方，则获取id。我所拥有的代码不是最好看的代码，但这里是我所拥有的，当你看到代码时，你可以理解它。我会稍微修改一下。以下代码来自我的模型

我想要做的是当检查多个复选框时，而不是获取与复选框中的任何一个匹配的所有行，我想获得与所有选中的复选框匹配的行。很抱歉，如果它难以理解和不幸，我无法向您显示页面，因为您需要登录。
