我有一个用户提交表单,其中一些字段是下拉列表
<div class="form-group row">
<label for="type" class="col-md-3 col-form-label text-md-right">Type</label>
<div class="col-md-9">
<select class ="form-control" id="type" name="type">
<option>Apartment</option>
<option>House</option>
<option>Studio</option>
<option>Flat</option>
</select>
@if ($errors->has('type'))
<span class="invalid-feedback">
<strong>{{ $errors->first('type') }}</strong>
</span>
@endif
</div>
</div>
这很好用。
我没有尝试允许用户编辑特定表单。我可以通过为输入分配值并像这样调用数据
来获取标题和照片等其他部分<input id="Address" type="text" class="form-control" name="address" value="{{$Advert->address }}" required autofocus>
但是当我尝试在选择选项上做类似的事情时,什么都没有出现。这是编辑页面上的下拉列表。
<div class="form-group row">
<label for="type" class="col-md-3 col-form-label text-md-right">Type</label>
<div class="col-md-9">
<select class ="form-control" id="type" name="type" value="{{$Advert->type}}">
<option></option>
<option>Apartment</option>
<option>House</option>
<option>Studio</option>
<option>Flat</option>
</select>
@if ($errors->has('type'))
<span class="invalid-feedback">
<strong>{{ $errors->first('type') }}</strong>
</span>
@endif
</div>
</div>
现在我可以用硬编码的价值来做我需要的事情
<select class ="form-control" id="type" name="type">
<option value="">Select</option>
<option {{ $Advert->type == 'Apartment' ? 'selected':'' }}>Apartment</option>
<option {{ $Advert->type == 'House' ? 'selected':'' }}>House</option>
<option {{ $Advert->type == 'Studio' ? 'selected':'' }}>Studio</option>
<option {{ $Advert->type == 'Flat' ? 'selected':'' }}>Flat</option>
</select>
但是我没有使用查询数据库的每个循环
@foreach ($Advert as $type)
<option {{ $type->type == '{{$type->type}}' ? 'selected':'' }}>{{$type->type}}</option>
@endforeach

您的代码应如下所示:
@foreach ($types as $type)
<option {{ $type->type == $Advert->type ? 'selected':'' }}>{{$type->type}}</option>
@endforeach

尝试使用以下代码:
@foreach ($types as $type)
<option @if($type->type == $Advert->type) selected @endif value="{{$type->type}}">{{$type->type}}</option>
@endforeach
