Laravel 所有控制器和视图的全局变量

发布于08月08日

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

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.

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