Question

我将视图中的fromdate和todate传递给控制器。我想从数据库中打印这些日期，但我得到的错误如下：

Symfony \ Component \ Debug \ Exception \ FatalThrowableError（E_ERROR）在字符串
上调用成员函数format（）

我的观看页面：

<div class="col-sm-4">
    {!! Form::open (['url' => 'admin/ad']) !!}
    <div class="form-group">
        {!! Form::label('', 'From date') !!}
        {!! Form::date('fromdate', '', ['class' => 'form-control']) !!}
        {!! Form::label('', 'To date') !!}
        {!! Form::date('todate', '', ['class' => 'form-control']) !!}
    </div>
    <div class="form-group">
        {!! Form::submit(('submit'), ['class' => 'btn btn-primary btn-block']) !!}
        {!! Form::close() !!}
    </div>
</div>

我的控制器页面：

$report = $request->report;
$fromdate = $request->fromdate; 
$start_date = date("Y-m-d H:i:s", strtotime($fromdate));
$todate = $request->todate;
$end_date = date("Y-m-d H:i:s", strtotime($todate));

$users = Report::whereBetween('created_at', [
    $start_date->format('Y-m-d') . " 00:00:00",
    $end_date->format('Y-m-d') . " 23:59:59"
])->get();

Answer 1

使用Carbon库来处理日期解析和格式化：

$users = Report::whereBetween('created_at', [
    Carbon::parse($request->fromdate)->toDateTimeString(), 
    Carbon::parse($request->todate)->toDateTimeString()
])->get();

请参阅 Modifiers 部分了解startOfXXXX格式：

$users = Report::whereBetween('created_at', [
    Carbon::parse($request->fromdate)->startOfDay(),  // 2012-01-31 00:00:00
    Carbon::parse($request->todate)->endOfDay()       // 2012-01-31 23:59:59
])->get();

Answer 2

好的，我使用

 {{ Carbon\Carbon::parse($object->yourdate_fromdatabase)->format('Y-m-d') }}

Answer 3

放置在模型中

protected $dates = ['fromdate', 'todate'];

Answer 4

您还可以使用DateTime

$report = $request->report;
$fromdate = $request->fromdate; 
$start_date = DateTime::createFromFormat("U", strtotime($fromdate));
$todate = $request->todate;
$end_date = DateTime::createFromFormat("U", strtotime($todate));

$users = Report::whereBetween('created_at', [
    $start_date->format('Y-m-d') . " 00:00:00", 
    $end_date->format('Y-m-d') . " 23:59:59"
])->get();

Answer 5

$report = $request->report;
$fromdate = $request->fromdate; 
$start_date = date("Y-m-d H:i:s", strtotime($fromdate));
$todate = $request->todate;
$end_date = date("Y-m-d H:i:s", strtotime($todate));
$users = Report::whereBetween('created_at', [$start_date,$end_date])->get();

在laravel中调用字符串上的成员函数format（）
