Question

在laravel中编辑表单时，我无法查看表单上传递的值。当我输入值时，它成功添加到表中。但是，当我想编辑值时，它们是不可见的。但是，当我在输入表单之外调用值时，我可以查看该值。

请参阅下面的代码。有人可以帮助我。谢谢。

       create.blade.php
       <div class="panel-heading">
                    <h3 class="panel-title">New Report Form</h3>
                </div>
                <div class="panel-body">
                    @include('errors.list')
                    @include('partials.success')
                    {!!    Form::open(['route'=>'crime_reports.store','class'=>'form-horizontal']) !!}

                         @include('crimereports._form')

                    <div class="form-group">

Answer 1

使用表单模型绑定时，应该将模型作为参数传递。你很亲密您拥有$crime_edit模型，但出于某种原因，您将其作为字符串传递。

更改此

{!! Form::model('$crime_edit',

这应该可以解决你的问题：

{!! Form::model($crime_edit,
