会话变量的值更改为'js'或'css'Codeigniter

我有一个名为'projects'的控制器显示所有保存在数据库通过视图和每个项目链接旁边的项目，以查看其详细信息，即将项目ID发送给控制器选择已点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，以便在我的所有过程中使用它。 我的问题是： 当我打电话给项目ID会话变量 - >在第一次调用它显示正确 - >但在第二次调用它显示'JS'或'CSS' 我不知道什么是我的项目ID和'js'或'css'之间的关系？ 为什么值改变了？会话变量的值更改为'js'或'css'Codeigniter

这里是我的代码：

您发布的代码中没有任何内容会解释此行为。这个问题可能在其他代码中没有显示。 – Utkanos

理想情况下，SO要求您只发布相关代码 - 否则是TL; DR。尝试在你的代码中找到你正在设置的地方，或者写上会话变量并发布它，而不是所有事情。 – Utkanos

有没有可能'$ row-> id'包含'css'或'js'值？你可以检查“项目”表吗？ –

要设置会话变量名： 'PROJECT_ID'

但在方法 “view_project_details_session”，你是试图获得'pid' 变量名称不同。

是的我知道并更正它为'project_id'，但问题仍然存在 –

+0

打印会话变量“project_id”value in view_project_details method“ admin_footer_view“，可能在方法执行结束时会话变量被覆盖。 –

+0

<？ echo $ this-> session-> userdata（'project_id'）;？> 在admin_footer_view.php中加入这个，你会得到什么？ –
