htmlspecialchars()期望参数1是字符串,数组给定laravel
问题描述:
我试图根据价格(从高到低和从低到高)在搜索页面中记录(旅游),用提交更改的表单事件。下面是窗体的代码:htmlspecialchars()期望参数1是字符串,数组给定laravel
{!!Form::open(['route' => 'short','method' => 'GET', 'role' => 'search','class'=>'select-filters'])!!}
<input type="hidden" name="country" value="{{$country}}">
<input type="hidden" name="category" value="{{$category}}">
<input type="hidden" name="days" value="{{$days}}">
<select name="sort_price" id="sort-price" onchange="this.form.submit()">
<option value="" selected="">Sort by price</option>
<option value="lower">Lowest price</option>
<option value="higher">Highest price</option>
</select>
{!! Form::close() !!}
,我已经初始化值在同一个页面,但给错误htmlspecialchars() expects parameter 1 to be string, array given
:
@if(Request::only('country') != null)
{{$country = Request::only('country')}}
@else
{{ $country = null }}
@endif
@if(Request::only('category') != null)
{{$category = Request::only('category')}}
@else
{{ $category = null }}
@endif
@if(Request::only('days') != null)
{{$days = Request::only('days')}}
@else
{{ $days = null }}
@endif
在Request::only()
值被从搜索表单传递在索引页面。当我死和转储:
{{dd(Request::only('country','category','days'))}}
我抛出以阵列形式传入的值
{{dd(Request::only('country'))}}
或
{{dd(Request::only('category'))}}
或
{{dd(Request::only('days'))}}
答
only()
总是返回一个数组,所以要得到一个字符串做到这一点:
{{ request('country') }}
取而代之的是:没有双引号
{{ Request::only('country') }}
