用消息檢索變量

Question

我正在嘗試檢索變量以便用消息這種方式顯示。但是，我知道這實際上不是一種方法。 $count是與消息一起顯示的變量。

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

只要改變

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

到

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

（雙引號來代替單）

您可能會看到this知道區別

Answer 2

這將工作：

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 . ' .'); 
    }
