Question

我只想显示我所拥有的特长，即它们在数据库的同一表中的值等于1，而当它等于0时不显示。我试图制作if语句，但它们返回错误。知道如何从数据库中获取值并进行检查吗？

@foreach($specialties as $key => $specialty)

    {{--@if ($value->{$key::is_template} = 1)--}}
    @if(value("{{$key->is_template}}") === 1)

    <li class="pcoded-hasmenu pcoded-trigger" dropdown-icon="style3" subitem-icon="style7">
        <a href="#">
            <span class="pcoded-micon"><i class="ti-calendar"></i><b>M</b></span>
            <span class="pcoded-mtext">{{$key}}</span>
            <span class="pcoded-mcaret"></span>
        </a>
        <ul class="pcoded-submenu">
            @foreach($specialty as $training)
            <li class=" ">
                <a href="{{route('practitionerView', $training->training_id)}}">
                    <span class="pcoded-micon"><i class="ti-angle-right"></i></span>
                    <span class="pcoded-mtext">{{$training->name}}</span>
                    <span class="pcoded-mcaret"></span>
                </a>
            </li>
            @endforeach
        </ul>
    </li>
    @endif
@endforeach

假设$specialties是这样的数组/集合：

$specialties = [
    'a' => new Specialty(['is_template' => 1]),
    'b' => new Specialty(['is_template' => 0]),
    'c' => new Specialty(['is_template' => 1]),
];

条件@if ($specialty->is_template === 1)或@if ($specialty->is_template)可行。

或者，如果您想保存几行，则可以用@foreach($specialties->where('is_template', 1) as $key => $specialty)替换foreach（这适用于Collection而不是常规数组）
