Question

我有一个关于如何从Laravel 5中的一个控制器将数组传递给多个视图的问题，是否可能？我想从一个函数索引（）传递一个数组到index.blade.php和home.blade.php。索引页面将显示所有数据，而主页仅显示一些数据。以下是代码

控制器：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Requests\EdisiRequest;
use App\Edisi;
use Session;
use Storage;

class EdisiController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $edisi_list = Edisi::all();
        return view('edisi/index', compact('edisi_list'));
    }
}

home.blade.php

@extends('template')

@section('main')
<div class="container sitecontainer bgw">
    <div class="row">
        <div class="col-md-12 col-sm-12 col-xs-12 m22 single-post">
            @if (count($edisi_list) > 0)
            <div class="reviewlist review-posts">
                <?php foreach ($edisi_list as $edisi): ?>
                    <div class="post-review col-md-4 col-sm-12">
                        <div class="post-media entry">
                            <a href="#" title="">

我尝试为主页制作另一个控制器，但仍然无法正常工作，它总是显示错误“$ edisi_list undefined variable”。如果还有其他方法请告诉我，谢谢！

EdisiServiceProvider.php

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use App\Edisi;

class EdisiServiceProvider extends ServiceProvider {

    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot() {
        View::composer(['edisi/index', 'pages/home'], function ($view) {
            $edisi_list = Edisi::all();
            $view->with('edisi_list', $edisi_list);
        });
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register() {
        //
    }

}

Answer 1

您可以使用view composer执行此操作：

 View::composer(['index', 'home'], function ($view) {
    $edisi_list = Edisi::all();
    $view->with('edisi_list', $edisi_list);
 });

Answer 2

对于任何其他使用View Composer传递数组的人，使用compact传递数组将不起作用。您必须直接发送：

在自定义作曲家中（在我的情况下为app/Http/View/Composers/UserInfoComposer.php）

public function compose( View $view ) {

    $allUserInfo = array();

    $generalFunctions      = new GeneralFunctions();
    $currentUserID         = $generalFunctions->getCurrentUserID();
    $currentUserName       = $generalFunctions->getCurrentUserName();
    $currentUserEmail      = $generalFunctions->getCurrentUserEmail();
    $currentUserProfilePic = $generalFunctions->getCurrentProfilePic();

    $allUserInfo['currentUserID']         = $currentUserID;
    $allUserInfo['currentUserName']       = $currentUserName;
    $allUserInfo['currentUserEmail']      = $currentUserEmail;
    $allUserInfo['currentUserProfilePic'] = $currentUserProfilePic;

    $view->with( 'allUserInfo', $allUserInfo );
//NOT: $view->with( 'allUserInfo', compact('allUserInfo'));

}
