Question

我正在尝试以这种方式检索变量以及消息。但是，我才知道这实际上不是一种方式。 $count是与消息一起显示的变量。

   public function now(Request $request)
      {
            $name=$request->get('name');
            $contact=$request->get('contact');
            $level=$request->get('level');

            $count=$level*3.5;
            return redirect('/lost')
                    ->with ('message','You have increased your level to $count.');
        }

Answer 1

这将有效：

<强> PHP

   public function now(Request $request)
   {
         $name=$request->get('name');
         $contact=$request->get('contact');
         $level=$request->get('level');

         $count=$level*3.5;
         return redirect('/lost')
                 ->with ('message','You have increased your level to ' . $count . ' .');
     }

Answer 2

只需更改

with ('message','You have increased your level to $count.');

到

with ('message',"You have increased your level to $count.");

（双引号而不是单引号）

您可能会看到this了解差异
