我一直在尝试使用url查找没有表单传递变量的信息，但我似乎无法找到与我的情况相关的任何问题。 基本上我需要有一个层次结构的页面，你可以从列表中单击一个课程，它会带你到一个部分列表，你可以点击一个部分，它将带来一个包含正确信息的页面对于那一节。我被告知这种情况使用$ _SESSION然后将变量包含在url中。我的问题是，每当我点击一个课程或一个部分时，每个单个课程或一个查询匹配的部分的信息都会显示而不仅仅是该课程或部分的信息。这就是我按层次顺序对每个页面所拥有的内容（不包括代码的连接部分，无论如何都可以正常工作）。我知道这是一大堆代码，而且完全混乱。我将继续搜索信息，并提前多多感谢您的帮助。

不要使用会话，只需将其包含在网址ex：example.com/index.php?example=true中。如果你使用$ _GET ['example']，它将具有值'true'。
