我试图在多个页面（不是全部）中使用相同的口才数据。
Class::isInstance()中需要数据
为此，我第一次使用view :: composer。
我遵循了laravel（5.4）网站上的文档。
我创建了以下内容：
App \ Providers \ ComposerServiceProvider
'view/board/segments/header'App \ Http \ ViewComposers \ Board \ MemberSettingsComposer
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class ComposerServiceProvider extends ServiceProvider
{
public function boot()
{
view()->composer(
'layouts.board.main',
'App\Http\ViewComposers\Board\MemberSettingsComposer'
);
}
public function register()
{
//
}
}
资源/视图/布局/board/main.blade.php
<?php
namespace App\Http\ViewComposers\Board;
use Illuminate\View\View;
use Auth;
use App\Models\BoardmembersDashboardSettings;
class MemberSettingsComposer {
public $settings;
public function __construct()
{
//$this->settings = BoardmembersDashboardSettings::find(Auth::user()->id);
$this->settings = BoardmembersDashboardSettings::where('id', Auth::user()->id)->first();
}
public function compose(View $view)
{
$view->with(compact('settings', $this->settings));
}
}
我尝试了几种选择：
<!DOCTYPE html>
<html lang="en">
<!-- Start including header -->
@include('board.segments.header')
<!-- End including header-->
<body class="framed main-scrollable">
<div class="wrapper">
<nav class="navbar navbar-static-top header-navbar">

@include('board.segments.navmobile')
<!-- End include Mobile Navigation -->

<!-- End include Brand Navigation -->
<div class="topnavbar">
<!-- Start include Top Navigation Left-->
@include('board.segments.navtopleft')
<!-- End include Top Navigation Left -->
<!-- Start include Top Navigation Right -->
@include('board.segments.navtopright')
<!-- End include Top Navigation Right -->
</div>
</nav>
<div class="dashboard">

</div>
</div>
</div>
<div class="scrollable scrollbar-macosx">

<!-- End include Side Menu Settings -->
</div>
</div>
</div>
<div class="main">
<div class="main__scroll scrollbar-macosx">
<div class="main__cont">
<div class="main-heading">
<div class="main-title">
<!-- Start include Breadcrumb -->
@include('board.segments.breadcrumb')
<!-- End include Breadcrumb -->

<div class="main-filter">
<!-- Start include Search -->
@include('board.segments.search')
<!-- End include Search -->
</div>
</div>
@yield('content')
</div>
</div>
</div>
</div>
</div>
<!-- Start include Footer -->
@include('board.segments.footer')
<!-- End include Footer -->
</body>
</html>
更改为'layouts.board.main' 'board.segments.header'。唯一不起作用的地方是视图。4次出现以下错误。
dd($this->settings)有人知道什么地方可能出了问题，然后尝试向我解释吗？
