Question

我安装了laravelcollective并尝试运行以下代码

{!! Form::open(['action' => 'ProductController@store','method' => 'POST']) !!}
    <div class="form-group">
        {{Form::label('title','Title')}}
        {{Form::text('title',['class' => 'form-control', 'placeholder' => 'Title'])}}
    </div>
{!! Form::close() !!}

我收到此错误

App\Http\Controllers\ProductController@store not defined. (View: /Applications/MAMP/htdocs/lsapp/resources/views/product/create.blade.php)

当我运行php artisan route：list时，我看到：

Answer 1

为了获得最佳实践并保持代码我希望遵循我的建议：

1）转到routes / web.php并为您的ProductController@store方法添加名称，如下所示：

Route::post('','ProductController@store')->name('products.store');

2）转到create.blade.php文件并将其更改为：

{!! Form::open(array( 'route'=>'products.store')) !!} 
    <div class="form-group">    
    {{Form::label('title','Title')}}  
    {{Form::text('title',['class' => 'form-control', 'placeholder' => 'Title'])}} 
    </div>

Answer 2

当您使用Laravel Collective表单时，不要将该方法声明为第二个参数，仅当您声明了一个url时，才将其用作路由参数，通常用于添加ID网址中需要一个。首先，尝试删除'method' => 'POST'部分，看看是否有效。

Answer 3

您是否在routes / web.php文件中创建了资源控制器或单个路由？

你有几个选择：

对于您的Form :: open，您可以使用 Action，Route或URL

行动：

   {!! Form::open(['action' => 'ProductController@store']) !!}
    // By default, a POST method will be assumed 
        <div class="form-group">
            {{Form::label('title','Title')}}
            {{Form::text('title',['class' => 'form-control', 'placeholder' => 'Title'])}}
        </div>
    // If you use the Form::open method with POST, PUT or DELETE the CSRF token will be added to your forms as a hidden field automatically.
    {!! Form::close() !!}

<强>路线：

首先在routes / web.php文件中命名您的路线：

Route::post('/productURL', 'ProductController@store')->name('productRouteName');

然后打开表单：

{!! Form::open(['route' => 'productRouteName'] !!}

<强> URL：

只需从上面创建的路线调用网址即可。

{!! Form::open(['url' => 'productURL'] !!}
