当我使用Php Storm时，

“提交”按钮显示为灰色而不是绿色。任何可以帮助我的问题。提前致谢

Answer 1

至于说“MassAssignmentException”，这意味着您尝试添加新数据，但尚未准备好正确的属性$ fillable

protected $guarded = ['price'];

https://laravel.com/docs/5.4/eloquent#mass-assignment

你也可以使用$ guared属性，只是为了保护你的数据。

<Image
    Grid.Column="0" Grid.Row="0"
    Source="add.png"
    HorizontalOptions="EndAndExpand"
    VerticalOptions="EndAndExpand"
    Margin="0,0,30,30"
    HeightRequest="45"
    WidthRequest="45">
    <Image.GestureRecognizers>
        <TapGestureRecognizer 
            Command="{Binding clickNewCard}"
            CommandParameter="3"
            Tapped="TapGestureRecognizer_Tapped"/>          
    </Image.GestureRecognizers>
</Image>

<Entry x:Name="StoreField" InputTransparent="True" IsVisible="False"/>

Answer 2

您应该在表单中添加csrf令牌字段以防止令牌不匹配异常：

在表单中使用此帮助程序：

{{ csrf_field() }}

或

<input type="hidden" name="_token" value="{{ csrf_token() }}">

此外，您的提交按钮的课程为btn-primary，这不是绿色！

Answer 3

你添加

{{ csrf_field() }}

使用普通表单时不是集合HTML。在您的模型中，您必须传递输入文件的名称

   // pass all the name in your form in your case just name
protected $fillable = ['name'];

或者您可以使用

protected $guarded // here you pass what is not going to add

Laravel 5.4未检测到提交按钮，并且给出了MassAssignmentException _token错误
