【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，我不知道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', $activities);
}
}
在客户端，我想遍历每个变量以将它们放入每个 UL 中
<div class="row pt-2">
@if(count($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 ($yearly->activity_free === true)
<li class="list-group-item"><h6 class="font-weight-bold">Free</h6></li>
@else
<li class="list-group-item"><h6 class="font-weight-bold">${{$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，所以我不能利用它们所做的 => 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
