可能的重复:
MySQL 插入多个表?(数据库规范化?)

我正在尝试使用 PDO 将我的记录插入到 2 个表中，我有以下内容

im trying to use PDO to insert my records into 2 tables, I have the following

try {
  // Connect and create the PDO object
 $conn = new PDO("mysql:host=$hostdb; dbname=$namedb", $userdb, $passdb);
$conn->exec("SET CHARACTER SET utf8");      // Sets encoding UTF-8
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

 $sql = "INSERT INTO `directory` (`First_Name`,`Surname`,`Nicknames`) 
      VALUES (:firstname, :surname, :nicknames) ";

 $statement = $conn->prepare($sql);
 $statement->bindValue(":firstname", $firstname);
 $statement->bindValue(":surname", $surname);
 $statement->bindValue(":nicknames", $nicknames);


 $count = $statement->execute();

  $conn = null;        // Disconnect
}
catch(PDOException $e) {
  echo $e->getMessage();
}

如果我使用(我认为是正确的)但是我的页面没有呈现并且没有源代码输出，那么可以将我的数据插入到 1 个表中?有人可以看看我是否在任何地方出错了吗?

that inserts my data into 1 table fine, if I use (What i presume to be corrct) however my page doesnt render and no source code is output? Can anybody see if im going wrong anywhere?

try {
  // Connect and create the PDO object
 $conn = new PDO("mysql:host=$hostdb; dbname=$namedb", $userdb, $passdb);
$conn->exec("SET CHARACTER SET utf8");      // Sets encoding UTF-8
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

 $sql = "INSERT INTO `directory`, `nicknames`  (`First_Name`,`Surname`,`Nicknames`) 
      VALUES (:firstname, :surname, :nicknames) ";

 $statement = $conn->prepare($sql);
 $statement->bindValue(":firstname", $firstname);
 $statement->bindValue(":surname", $surname);
 $statement->bindValue(":nicknames", $nicknames);


 $count = $statement->execute();

  $conn = null;        // Disconnect
}
catch(PDOException $e) {
  echo $e->getMessage();
}

推荐答案

那不是有效的 SQL；你需要分开做.也许:

That’s not valid SQL; you need to do them separately. Maybe:

$sql = "
    INSERT INTO `directory`(`First_Name`,`Surname`,`Nicknames`) VALUES (:firstname, :surname, :nicknames);
    INSERT INTO `nicknames`(`First_Name`,`Surname`,`Nicknames`) VALUES (:firstname, :surname, :nicknames);
";
