Question

我是laravel的新手，请在以下情况下为我提供帮助，我有一个需要三个参数的函数

public function myfunction (Request $request)
{
    $first=$request->first;
$second=$request->second;
$third=$request->third;
{some calculation here }
return view('report/myrepo1,.......)}

现在我有刀片，每个其他这样的$ variable这样的循环都位于

@foreach($var as $v)
 <tr>{{<td>$v->first}}</td>
<td>{{$v->second}}</td>
<td>{{$v->third}}</td>
<td>{{  ?????  //How to cal the function which i wrote in controller }} 
//if i am doing calling a function as we do in C or C++ it show error}}
    //like this {{myfunction($value->first,$value->second,$value->third)}}

任何想法如何解决这类问题谢谢

Answer 1

您必须在刀片文件中调用Controller函数例如：

{{\App\TestController::TestFunction($item->id)}}

Answer 2

您可以在服务提供商内部使用Blade :: facade定义自定义的Blade指令，即app\Providers\AppServiceProvider.php如下所示：

在您的app\Providers\AppServiceProvider.php的启动方法中

//Blade directive to myfunction.
Blade::directive('myfunction', function ($a1, $a2, $a3) {
    //Do calculations you want here and return back..
    return $a1 + $a2 + $a3;
});

在刀片文件中

@foreach($var as $v)
    <td>{{ @myfunction($v->first, $v->second, $v->third) }} </td>
@endforeach

如何在laravel中将值从刀片传递到控制器？
