用的laravel5.2框架，下面这个调研问卷的控制器怎么写？demo如下：

数据表有3张，1和2多对多关系：
1、respondents //受访者
2、sports //喜欢的运动
3、sport_respondent //关联表

respondents

id name email

sports

id sport_name 1 Basketball 2 Football 3 Table tennis 4 Badminton 5 Baseball 6 Swimming

sport_respondent

id respondent_id sport_id

视图：

        
  
 
 
 Name  
 
 Email  
 
  Basketball   Football   Table tennis   Badminton   Baseball   Swimming  
 Submit 
 
     

问题：控制器怎么写？

public function store(Request $request) { $respondent= new Respondent; $respondent->name = $request->name; $respondent->email = $request->email; $respondent->save(); $sport = new Sport; //接下来怎么写？ return redirect()->action('RespondentController@index'); }

public function store(Request $request) { $params = $request->all(); $respondent= new Respondent; $respondent->name = $params['name']; $respondent->email = $params['email']; $respondent->save(); $respondent->sports()->attach($params['sportd_ids']); }
