完整性約束違規：1048列的'名稱'不能爲空

Question

我正在使用PHP和和Slim框架爲REST API註冊用戶。 它給我一個錯誤，當我在先進的REST客戶端運行：

{"error":{"text":SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'name' cannot be null}}

用於暫存模塊的代碼如下：

function insertUpdate() { 
    $request = \Slim\Slim::getInstance()->request(); 
    $update = json_decode($request->getBody()); 
    $sql = "INSERT INTO users (name,email,password,phoneNumber,imageUrl,created_at) VALUES (:name, :email, :password, :phoneNumber, :imageUrl, :created_at)"; 
    try { 
     $db = getDB(); 
     $stmt = $db->prepare($sql); 
     $stmt->bindParam("name", $update->name); 
     $stmt->bindParam("email", $update->email); 
     $stmt->bindParam("password",$update->password); 
     $stmt->bindParam("phoneNumber",$update->phoneNumber); 
     $stmt->bindParam("imageUrl",$update->imageUrl); 
     $time=time(); 
     $stmt->bindParam("created_at", $time); 

     $stmt->execute(); 
     echo "Register successfull"; 
    } catch(PDOException $e) { 
     //error_log($e->getMessage(), 3, '/var/tmp/php.log'); 
     echo '{"error":{"text":'. $e->getMessage() .'}}'; 
    } 
} 

堆棧跟蹤：

#1 [internal function]: insertUpdate()

如何解決此錯誤？

function insertUpdate() { 
     $request = \Slim\Slim::getInstance()->request(); 
     parse_str($request->getBody(),$update); 
     $sql = "INSERT INTO users (name,email,password,phoneNumber,imageUrl,created_at) VALUES (:name, :email, :password, :phoneNumber, :imageUrl, :created_at)"; 
     try { 
      //Validate your filed before insert in db 
      if(!is_array($update) || (!$update)) { 
       throw new Exception('Invalid data received'); 
      } 
      // put your require filed list here 
      if((!$update['name']) || (!$update['email']) || (!$update['password'])){ 
       throw new Exception('Missing values for require fields'); 
      } 
      $db = getDB(); 
      $stmt = $db->prepare($sql); 
      $stmt->bindParam("name", $update['name']); 
      $stmt->bindParam("email", $update['email']); 
      $stmt->bindParam("password",$update['password']); 
      $stmt->bindParam("phoneNumber",$update['phoneNumber']); 
      $stmt->bindParam("imageUrl",$update['imageUrl']); 
      $time=time(); 
      $stmt->bindParam("created_at", $time); 

      $stmt->execute(); 
      echo "Register successfull"; 
     } catch(PDOException $e) { 
      //error_log($e->getMessage(), 3, '/var/tmp/php.log'); 
      echo '{"error":{"text":'. $e->getMessage() .'}}'; 
     }catch(Exception $e) { 
      //error_log($e->getMessage(), 3, '/var/tmp/php.log'); 
      echo '{"error":{"text":'. $e->getMessage() .'}}'; 
     } 
    }
