所有控制器和视图的全局变量 [英] global variable for all controller and views

问题描述

在Laravel中，我有一个表设置，我从BaseController的表中获取了完整的数据，如下所示：

  public函数__construct（）
 {
 //获取站点设置对象
 $ site_settings =设置:: all（）; 
查看:: share（'site_settings'，$ site_settings）; 
} 
  

现在我想访问$ site_settings。在所有其他控制器和视图中，我不需要一次又一次地写相同的代码，所以任何人都可以告诉我解决方案或任何其他方式，这样我就可以从表中获取数据并在所有控制器中使用它，首先，一个配置文件适合这种事情，但你也可以使用另一种方法，它是（Laravel - 4）：

  //你可以保存在你的filters.php文件中
 App :: before（function（$ request）{
 App :: singleton（'site_settings'，function（）{
 return Setting :: all（）; 
}）; 
 
 //如果你使用这行代码，那么它可以在任何视图
 //作为$ site_settings使用，但你也可以使用app（'site_settings'）以及
 View： ：share（'site_settings'，app（'site_settings'））; 
}）; 
  

要获取任何控制器中的相同数据，您可以使用：

  $ site_settings = app（'site_settings'）; 
  

有很多方法，只需使用其中一种，您更喜欢哪种方式，但我使用容器。

In Laravel I have a table settings and i have fetched complete data from the table in the BaseController, as following

public function __construct() 
{
    // Fetch the Site Settings object
    $site_settings = Setting::all();
    View::share('site_settings', $site_settings);
}

Now i want to access $site_settings. in all other controllers and views so that i don't need to write the same code again and again, so anybody please tell me the solution or any other way so i can fetch the data from the table once and use it in all controllers and view.

解决方案

At first, a config file is appropriate for this kind of things but you may also use another approach, which is as given bellow (Laravel - 4):

// You can keep this in your filters.php file
App::before(function($request) {
    App::singleton('site_settings', function(){
        return Setting::all();
    });

    // If you use this line of code then it'll be available in any view
    // as $site_settings but you may also use app('site_settings') as well
    View::share('site_settings', app('site_settings'));
});

To get the same data in any controller you may use:

$site_settings = app('site_settings');

There are many ways, just use one or another, which one you prefer but I'm using the Container.
