插入数据PDO的问题

Question

我正在尝试插入用户遇到的问题（注册表），但没有插入数据，同时没有错误或原因，我检查了日志和所有内容，似乎没有错。 但是我的查询没有执行。

  /* IN THIS FUNCTION WE REGISTER THE USER, WE CREATE A SALT, INSERT THAT SALT KEY INTO SALTS TABLE, THEN GET THE ID AND USE THAT ID IN PASSYSTEM TABLE WHERE WE STORE THE PASSWORD AND THE SALT ID THE MEMBER DATA IS STORED IN MEMBERS TABLE*/
    $data = $_POST;
    print_r($data);
    $salt = $this->gen_salt();
    $password =  hash('sha512', $salt.$data['password'].$salt, FALSE);
    print $password;
      $membersql = "INSERT INTO member (`firstname`,`lastname`,`email`,`gender`) VALUES (:firstname, :lastname, :email, :gender)";
      $memberquery = $db->prepare($membersql);
      $memberquery->bindParam(':firstname', $data['firstname'], PDO::PARAM_STR);
      $memberquery->bindParam(':lastname', $data['lastname'], PDO::PARAM_STR);
      $memberquery->bindParam(':email', $data['email'], PDO::PARAM_STR);
      $memberquery->bindParam(':gender', $data['gender'], PDO::PARAM_STR);

      $memberquery->execute();

Answer 1

似乎bindparam有问题。

像这样尝试：

$membersql = "INSERT INTO member (firstname,lastname,email,gender) VALUES (?, ?, ?, ?)";
$memberquery->execute(array($data['firstname'], $data['lastname'], $data['email'], $data['gender']));

这应该正常工作。
