php - 如何使用雄辩的“with”来传递多个数组的数组以进行循环

问题描述

我正在尝试为单个 SQL 表中的不同过滤行创建一个具有不同 uls 的页面。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”为视图提供多个数组，我将直接发布代码，以便更好地了解我的内容正在尝试做。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一个变量中，所以我决定将它作为数组传递

<?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，我想遍历每个变量以将它们放入每个 UL

<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 ($yearly->activity_free === true)
                                    <li class="list-group-item"><h6 class="font-weight-bold">Free</h6></li>
                                @else
                                    <li class="list-group-item"><h6 class="font-weight-bold">${{$yearly->activity_low_cost}} - ${{$yearly->activity_high_cost}}</h6></li>
                                @endif
                            </ul>
                            <div class="card-body">
                                <a href="/activities/{{$yearly->id}}" class="card-link">View Activity</a>
                                <a href="/" class="card-link float-right">Save</a>
                            </div>
                        </div>
                    </div>
                @endforeach
            @else
                <h5 class="text-secondary text-center">No yearlies available</h5>
            @endif
        </div>

希望我正在尝试做的事情有点明显。无论如何，我一直在搜索，我看到的只是关于集合的东西，但我并没有亲自定义不同的子值，所以我不能利用他们所做的 => 功能。任何帮助表示赞赏。

编辑：下面是 $activities 的 dd，我想知道如何通过这个导航到每年的每一行

array:1 [▼
  0 => array:3 [▼
    "yearlies" => Illuminate\Database\Eloquent\Collection {#262 ▼
      #items: array:1 [▼
