Question

我收到此错误是什么原因

“未定义的变量：引号”

QuotationController.php

public function update(Request $request, Quotation $quotation)
    {
      {


          $quotation->description= $request['description'];
          $quotation->qty= $request['qty'];
          $quotation->each_price= $request['each_price'];
          $quotation->save();

         $info = ['info'=>$quotation];

         Mail::send(['text'=>'mail'], $info, function($message){

             $pdf = PDF::loadView('employees.quotations.edit', $quotation);

             $message->to('example@gmail.com','John Doe')->subject('Quotation');

             $message->from('from@gmail.com','The Sender');

             $message->attachData($pdf->output(), 'filename.pdf');

           });
          echo 'Email was sent!';

        }
      }

public function edit(Quotation $quotation)
    {
        return view('employees.quotations.edit', compact('quotation'));
        //return view('employees.quotations.edit')->with('quotation');

    }

............................................... .......................

路线如下

Route::post('/quotation', 'Employee\QuotationController@store')->name('employee.quotation.store');
  Route::get('/quotation', 'Employee\QuotationController@index')->name('employee.quotation.index');
  Route::get('/quotation/create', 'Employee\QuotationController@create')->name('employee.quotation.create');
  Route::put('/quotation/{quotation}', 'Employee\QuotationController@update')->name('employee.quotation.update');
  Route::get('/quotation/{quotation}', 'Employee\QuotationController@show')->name('employee.quotation.show');
  Route::delete('/quotation/{quotation}', 'Employee\QuotationController@destroy')->name('employee.quotation.destroy');
  Route::get('/quotation/{quotation}/edit', 'Employee\QuotationController@edit')->name('employee.quotation.edit');

employees.quotations.edit.blade.php看起来像这样

@section('left-menu')

@endsection

@section('right-menu')

@endsection

@section('content')
  <h1>Update a Quotation</h1>
  <br><br>

    </form>

我在这里想念什么？我已经将$ quotation传递给了修改视图

Answer 1

为什么要使用双括号声明函数？为什么不呢？

public function update(Request $request, Quotation $quotation)
    {
      


          $quotation->description= $request['description'];
          $quotation->qty= $request['qty'];
          $quotation->each_price= $request['each_price'];
          $quotation->save();

         $info = ['info'=>$quotation];

         Mail::send(['text'=>'mail'], $info, function($message){

             $pdf = PDF::loadView('employees.quotations.edit', $quotation);

             $message->to('example@gmail.com','John Doe')->subject('Quotation');

             $message->from('from@gmail.com','The Sender');

             $message->attachData($pdf->output(), 'filename.pdf');

           });
          echo 'Email was sent!';

        
      }

Answer 2

您显然没有在路由中传递$quotation变量。您还使用$quotation作为对象；告诉我您不打算通过路线。尝试以下代码：

public function update(Request $request, $quotation_id)
    {
      $quotation = Quotation::findOrFail($quotation_id);

      $quotation->description= $request['description'];
      $quotation->qty= $request['qty'];
      $quotation->each_price= $request['each_price'];
      $quotation->update();

     $info = ['info'=>$quotation];

     Mail::send(['text'=>'mail'], $info, function($message) use ($quotation){

         $pdf = PDF::loadView('employees.quotations.edit', $quotation);

         $message->to('example@gmail.com','John Doe')->subject('Quotation');

         $message->from('from@gmail.com','The Sender');

         $message->attachData($pdf->output(), 'filename.pdf');

       });
      echo 'Email was sent!';

    }

这应该有效。

Answer 3

我认为您需要将$quotation传递给闭包：

    Mail::send(['text' => 'mail'], $info, function ($message) use ($quotation) {

        $pdf = PDF::loadView('employees.quotations.edit', $quotation);

        $message->to('example@gmail.com', 'John Doe')->subject('Quotation');

        $message->from('from@gmail.com', 'The Sender');

        $message->attachData($pdf->output(), 'filename.pdf');

    });
