使用CI挂钩设置公共变量(Use CI hook to set common variables)

使用CI挂钩设置公共变量(Use CI hook to set common variables)

我有几个常见的变量，我想用钩子设置。 例如我有一个post_controller_constructor钩子，在这里我想执行一些逻辑来设置用户主文件夹：

public function post_controller_constructor() { $home_folder = isset($_SESSION['hf']) ? $_SESSION['hf'] : NULL; // Check whether the homefolder value has been set $home_folder = isset($_SESSION['hf']) ? base_url($_SESSION['hf']) : base_url('default'); }

但是如何将生成的变量$ home_folder传递回控制器？

I have several common variables which I want to set using a hook. For example I have a post_controller_constructor hook, inside this I want to perform some logic to set the users home folder:

public function post_controller_constructor() { $home_folder = isset($_SESSION['hf']) ? $_SESSION['hf'] : NULL; // Check whether the homefolder value has been set $home_folder = isset($_SESSION['hf']) ? base_url($_SESSION['hf']) : base_url('default'); }

But how do I pass the resulting variable $home_folder back to my controllers?

最满意答案

public function post_controller_constructor() { $home_folder = isset($_SESSION['hf']) ? $_SESSION['hf'] : NULL; // Check whether the homefolder value has been set $home_folder = isset($_SESSION['hf']) ? base_url($_SESSION['hf']) : base_url('default'); $CI =& get_instance(); $CI->home_folder = $home_folder; }

会这样做。

public function post_controller_constructor() { $home_folder = isset($_SESSION['hf']) ? $_SESSION['hf'] : NULL; // Check whether the homefolder value has been set $home_folder = isset($_SESSION['hf']) ? base_url($_SESSION['hf']) : base_url('default'); $CI =& get_instance(); $CI->home_folder = $home_folder; }

Would do it.
