Laravel 5.3向数据库查询并传递所有视图 [英] Laravel 5.3 make a query to database and pass it all views

问题描述

我有一些要从数据库中获取的动态数据，并将其传递给所有视图.我试图从互联网上举一些例子，但是在我这样的情况下，它们似乎不起作用

I have a some dynamic data that I want to fetch from database and pass it to all views. I tried to make some examples from internet but they seems to be not working in my situation like

public function boot(){}

我无法进行数据库查询的

只传递硬编码的值.我尝试过的另一种方法是基本控制器，但是访问变量

to which I can't make a database query only pass hardcoded values. Another method I have tried is a base controller but the view gives me error when accessing the variable

$query = DB::table('users')->first();
\View::share('user', $query);

任何人都有基于BaseController的解决方案将不胜感激，如果我错过了什么，请提醒我

Anyone have a BaseController based solution will be appreciated and if I missed something please do remind me

推荐答案

根据

有时，您可能需要与应用程序呈现的所有视图共享一条数据.您可以使用View Facade的share方法来实现.通常，您应该在服务提供商的启动方法中发出要共享的调用.

Occasionally, you may need to share a piece of data with all views that are rendered by your application. You may do so using the view facade's share method. Typically, you should place calls to share within a service provider's boot method.

以该站点为例，您应将其添加到您的服务提供商之一:

Again as an example in that site you should add this to one of your service providers:

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
        if (!app()->runningInConsole()) {
            $query = DB::table('users')->first();
            \View::share('user', $query);
        }
    }
}
