仅删除标题栏的重复项

Question

在我的web控制器中的laravel 5.7中

public function index(Request $request){

    $plan = Plan::All();

    return view('web.plan.index', compact('plan'));
}

在我的视图文件中

                   @foreach($plan as $singlePlan)
                   
                  @if(Carbon\Carbon::parse($singlePlan->date)->format('m')==10)
                        
                        <div class="row brow bg-gray ">
                            <div class="col-md-12">
                                <div class="row-title">
                                    <strong>12.31</strong>

                    <div class="m-departures">

                @endif
                      @endforeach

我的网页看起来像this

但我希望它看起来像this

如何删除重复的标题？

Answer 1

在将数据传递到刀片式服务器模板之前，最好按月对数据进行分组。通过使用集合方法mapToGroups https://laravel.com/docs/8.x/collections#method-maptogroups

$planGroups = Plan::get()->mapToGroups(function($plan, $key) {
    $planDate = \Carbon\Carbon::parse($plan->date);

    return ["{$planDate->month} {$planDate->year}" => $plan];
})
->all();

你将得到几组按月分组的计划，例如

[
    '11 2020' => [plan, plan, ...],
    '12 2020' => [plan, plan, plan, ...]
]

然后在您的刀片模板中，您可以循环通过月份，然后循环通过计划。

@foreach ($planGroups as $month => $plans)
    // show month heading

    @foreach ($plans as $plan)
        // show each plan
    @endforeach
@endforeach
