Question

我试图将变量传递给我的主人＆＃39;布局：

//views/dashboard/layouts/master.blade.php

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
    </head>

<body>
  @yield('site.body');
  {{{ isset($test) ? $title:'Test no exists :) ' }}}
</body>
</html>

现在在我的DashboardController中：

class DashboardController extends BaseController
{
    public $layout = "dashboard.layouts.master"; 

    // this throw error : Cannot call constructor
    //public function __construct()
    //{
    //    parent::__construct();
    //    $this->layout->title = 'cry...';
    //} 

    // this throw error : Attempt to assign property of non-object 
    // and I understand it, coz $layout isn't an object

    //public function __construct()
    //{
    //    $this->layout->title = 'cry...';
    //} 

    public function action_doIndex()
    {
        $this->layout->title = 'this is short title';
        $this->layout->body = View::make('dashboard.index');

    }

    public function action_doLogin()
    {
        //$this->layout->title = 'this is short title'; // AGAIN ???
        $this->layout->body = View::make('dashboard.forms.login');
    }

    public function action_doN()
    {
       // $this->layout->title = 'this is short title'; // AND OVER AGAIN ?!?!
    }

}

我想只设置ONCE $ title变量，当我想要它时 - 覆盖它。现在我每次调用另一个方法时都必须设置变量：/

怎么做？如何为此＆＃39; master＆＃39;设置$ title变量仅ONCE布局??

Answer 1

您可以使用View::composer()或View::share()将“变量”传递给您的观看次数：

public function __construct()
{
    View::share('title', 'cry...');
}

这是作曲家：

View::composer('layouts.master', function($view)
{
    $view->with('name', Auth::check() ? Auth::user()->firstname : '');
});

如果您在所有观看中都需要它，您可以：

View::composer('*', function($view)
{
    $view->with('name', Auth::check() ? Auth::user()->firstname : '');
});

您甚至可以为此目的创建文件，例如app/composers.php，并将其加载到app/start/global.php中：

require app_path().'/composers.php';
