Question

我试图提取所有客户信息，它应该工作，因为它是一个循环信息的简单foreach。完全混淆为什么我得到一个未定义的变量，理论上这应该不起作用？

路线档案

 Route::group(array('before' => 'auth'), function() {
      // Get Customer (GET)
      Route::get('/customer/clientlist', array(
        'as' => 'clientlist',
        'uses' => 'CustomerController@getCustomers'
        ));
    });

型号：

class Customer extends Eloquent {
     //Mass assignment for security
     protected $fillable = array('address', 'city', 'postcode',
                          'phone', 'mobile', 'contact', 'user_id');    
    //protected $table = 'customers';
    public function user() {
       return $this->hasMany('User');
    }
  }

控制器：

class CustomerController extends BaseController {
    public function getCustomers() {
      $customers = Customer::all();
      //var_dump($customers);
      return View::make('customer.clientlist', array('customers'=>$customers));
    } 
  }

@foreach($customers as $customer)
  <div class="customer-card col-md-4">

@endforeach

这是我目前得到的错误异常，我无法理解为什么我继续这样做，如果我注释掉控制器并将静态信息放入视图中它确实有效。

ErrorException

未定义的变量：customers（查看：/Users/Sites/nit/app/app/views/customer/clientlist.blade.php） <?php echo $__env->make('customer.clientlist', array('customers'=>$customers), array_except(get_defined_vars(), array('__data', '__path')))->render(); ?>

我看到了问题 - 你自己包含customer.clientlist文件。

在您的控制器中拨打

return View::make('customer.clientlist', array('customers'=>$customers));

然后在你的视图中再次调用

@include('customer.clientlist', array('customers'=>$customers))

创建无限循环。我猜它应该是

@include('customer.viewclientlist', array('customers'=>$customers))

正如@Joseph Silber所提到的那样 - 你实际上不需要再传递包含在数组中的数组了 - 所以这样做是为了清理你的代码：

@include('customer.viewclientlist')
