symfony3でお問い合せのページを作成しているのですが、DBに保存する際に、下記のエラーが出て原因が追求できません。

```

    *An exception occurred while executing 'INSERT INTO inquiry (name, email, tel, type, content) VALUES (?, ?, ?, ?, ?)' with params [null, null, null, null, null]:
    SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'name' cannot be null*
    
```

          return $this->content;
      }
    }
    
```

Controllerの以下の時点で各$dataのvalueがnullになることを確認しており、上記エラーメッセージが出るのだと思いますが、何故valueがnullになるのか原因が分かりません。

```

    $inquiry = new Inquiry();
    $inquiry->setName($data["name"]);
    $inquiry->setEmail($data["email"]);
    $inquiry->setTel($data["tel"]);
    $inquiry->setType($data["type"]);
    $inquiry->setContent($data["content"]);
    
```

また、Entityで以下のように引数もセットして試したましたが、エラーは解消しませんでした。  
どなたか原因がわかる方、ご教示願います。

```

    public function setTel($tel)
    {
        return $this->tel;
    }
    
```
