如何使用雄辩的“with”传递多个数组的数组进行循环

Question

我正在尝试创建一个页面，该页面在单个SQL表中具有不同的过滤行。在过去的几个小时里，我一直在尝试和搜索，看看如何使用“with”为多个数组提供视图，我将直接发布代码，以便它可以更好地了解我正在尝试做的事情。由于每个数组使用不同的SQL参数，我不确定如何将它们全部收集到单个变量中，所以我决定将其作为数组传递

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Activity;

class ActivityController extends Controller

{

    public function index (){

        $activities[] = [

            'yearlies' => Activity::all()

                ->where('activity_feature_type', 'yearly')

                ->sortByDesc('activity_daily_budget')

                ->take(6),

            'monthlies' => Activity::all()

                ->where('activity_feature_type', 'monthly')

                ->sortByDesc('activity_daily_budget')

                ->take(4),

            'weeklies' => Activity::all()

                ->where('activity_feature_type', 'weekly')

                ->sortByDesc('activity_daily_budget')

                ->take(4),

        ];

        return view('activities')->with('activities', $activities);

    }

}

在客户端，我想遍历每个变量，将它们放入每个 UL 中

<div class="row pt-2">

            @if(count($yearlies) > 0)

                @foreach($activities['yearlies'] as $yearly)

                    <div class="col-sm-2">

                        <div class="card" style="width: 18rem;">

                            <img class="card-img-top" src="img/{{$yearly->activity_picture_link}}" alt="Card image cap">

                            <div class="card-body">

                                <h5 class="card-title">{{$yearly->name}}</h5>

                                <p class="card-text">{{$yearly->activity_desc_short}}</p>

                            </div>

                            <ul class="list-group list-group-flush">

                                @if ($yearly->activity_free === true)

                                    <li class="list-group-item"><h6 class="font-weight-bold">Free</h6></li>

                                @else

希望我能做什么有点明显。无论如何，我一直在搜索，我所看到的只是关于集合的东西，但我没有亲自定义不同的子值，所以我不能利用=>功能。任何帮助是值得赞赏的。

当您在一个数组变量中发送值时，这意味着它是多维数组。另外，而不是$activities[] = [&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'yearlies' => Activity::all()&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->where('activity_feature_type', 'yearly')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->sortByDesc('activity_daily_budget')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->take(6),&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'monthlies' => Activity::all()&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->where('activity_feature_type', 'monthly')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->sortByDesc('activity_daily_budget')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->take(4),&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'weeklies' => Activity::all()&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->where('activity_feature_type', 'weekly')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->sortByDesc('activity_daily_budget')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->take(4),&nbsp; &nbsp; &nbsp; &nbsp; ];用$activities = [&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'yearlies' => Activity::all()&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->where('activity_feature_type', 'yearly')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->sortByDesc('activity_daily_budget')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->take(6),&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'monthlies' => Activity::all()&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->where('activity_feature_type', 'monthly')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->sortByDesc('activity_daily_budget')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->take(4),&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'weeklies' => Activity::all()&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->where('activity_feature_type', 'weekly')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->sortByDesc('activity_daily_budget')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ->take(4),&nbsp; &nbsp; &nbsp; &nbsp; ];这将降低数组的复杂性。另外，在您的文件中 -blade<div class="row pt-2">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; @if(isset($activities) || $activities!= null)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; @foreach($activities['yearlies'] as $yearly)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="col-sm-2">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="card" style="width: 18rem;">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <img class="card-img-top" src="img/{{$yearly->activity_picture_link}}" alt="Card image cap">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="card-body">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <h5 class="card-title">{{$yearly->name}}</h5>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <p class="card-text">{{$yearly->activity_desc_short}}</p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <ul class="list-group list-group-flush">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; @if ($yearly->activity_free === true)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <li class="list-group-item"><h6 class="font-weight-bold">Free</h6></li>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; @endif&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </ul>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="card-body">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <a href="/activities/{{$yearly->id}}" class="card-link">View Activity</a>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <a href="/" class="card-link float-right">Save</a>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </div>&nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; @else&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <h5 class="text-secondary text-center">No yearlies available</h5>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; @endif&nbsp; &nbsp; &nbsp; &nbsp; </div>我想这会很好。如果我错了，请纠正我。希望这对你有用。
