我有控制器叫＆＃39;项目＆＃39;显示在db通过视图和每个项目链接旁边保存的所有项目，以查看其详细信息，即将项目ID发送到控制器以选择单击的项目并显示其详细信息。 我需要将项目id存储在会话变量中，以便在我的所有进程中使用它。 我的问题是： 当我调用项目id会话变量时 - ＆gt;在第一次调用它正确显示它 - ＆gt;但在第二次调用它时显示＆＃39; js＆＃39;或者＆＃c;＆＃39; 我无法知道我的项目ID和＆＃39; js＆＃39;之间的关系。或者＆＃c;＆＃39; ?? 价值变动的原因???
这是我的代码：

请知道
答案 0 :(得分：0)
您正在设置会话变量名称：＆＃39; project_id＆＃39;
但是在方法＆＃34; view_project_details_session＆＃34;中，您正试图获得＆＃39; pid＆＃39; 变量名称不同。
