我正面临着Laravel的一个问题，因为我试图让它在第一次出现时停止。因此，从下面的代码中可以看出，我的刀片文件中有不同类型的政府。问题是，它循环通过该类型的所有政府角色并且它触发计数＆lt; 1次多次，看起来不太友好。
代码：
<div class="col-md-8">
<div class="tab-content">
<div class="tab-pane active" id="higher_government_team">
<div class="panel panel-info">
<div class="panel panel-body">
@if ($royalty->count() < 1)
We couldn't find any government roles for this category.
@else
@foreach($royalty as $key => $governmentRole)
@if (count($governmentRole->stats) < 1)
There are currently no candigates working in this category.
@else
@foreach($governmentRole->stats as $governmentMember)

这部分代码大约闪了10次，我想要做的只是发射一次所以看起来干净又友好。我希望它为每个标签面板触发一次。
@if (count($governmentRole->stats) < 1)
There are currently no candigates working in this category.
@else
当前输出： 目前没有此类别的候选人。目前没有此类别的候选人。目前没有此类别的候选人。目前没有此类别的候选人。目前没有此类别的候选人。目前没有此类别的候选人。目前没有此类别的候选人。
我想要的输出： 目前没有此类别的候选人。

只需使用@break指令退出循环：
@if (count($governmentRole->stats) < 1)
There are currently no candigates working in this category.
@break
@else

您可以使用forelse执行此操作。如果集合为空，forelse将遍历集合或显示消息。
@forelse($governmentRole->stats as $governmentMember)
<div class="col-md-10">
<div class="col-md-12" style="margin-left:-40px;">
<div class="col-md-1" style="margin-top:-16px;"><img src="http://mywebsite.com/os734zl?figure=ch-3030-92.hr-681-34.hd-209-8.lg-3116-106-1408&size=b&direction=3&head_direction=3"></div>
<div class="col-md-9" style="margin-left:40px;">
<h4>{{ $governmentMember->user->username }} <small>{{ $governmentRole->government_title }}</small></h4>
<p><font color="#aaa">{{ $governmentRole->government_department }}</font></p><br>
</div>
</div>
</div>
@empty
There are currently no candigates working in this category.
@endforelse

您必须在开始循环之前进行检查并忽略空结果集。您可以使用Laravel Collections检查集合是否包含任何结果。像这样：
@if ($royalty->count() < 1)
We couldn't find any government roles for this category.
@elseif ($royalty->filter(function ($r) { return $r->stats->count() > 0; })->isEmpty()
There are currently no candigates working in this category.
@else
@foreach($royalty as $key => $governmentRole)
<!-- Your loop code, no 'if' needed anymore -->
@endforeach
@endif
