的mysqli插入錯誤 - 調用一個成員函數bind_param

我得到了這個非常簡單的mysqli查詢失敗並返回此消息：的mysqli插入錯誤 - 調用一個成員函數bind_param

Fatal error: Uncaught Error: Call to a member function bind_param() on boolean in M:\xampp\htdocs\insert\form-handler.php:17 Stack trace: #0 {main} thrown in M:\xampp\htdocs\insert\form-handler.php on line 17

HTML：

<!DOCTYPE html> 
<html lang="en"> 
<head> 
    <meta charset="UTF-8"> 
    <title>Document</title> 
</head> 
<body> 
    <form action="form-handler.php" method="POST"> 
     <input type="text" name="firstname"> 
     <input type="text" name="lastname"> 
     <input type="submit"> 
    </form> 
</body> 
</html>

PHP：

$firstname = $_POST['firstname']; 
$lastname = $_POST['lastname']; 

$mysqli = new mysqli('localhost', 'root', '', 'firstlast'); 

if (mysqli_connect_errno()) { 
    printf("Connect failed: %s\n", mysqli_connect_error()); 
    exit(); 
} 

$stmt = $mysqli->prepare('INSERT INTO users (id, firstname, lastname) VALUES ("", ?, ?'); 

$stmt->bind_param('ss', $firstname, $lastname); 

$stmt->execute(); 

$stmt->close();

有什麼我錯過了？謝謝。

大地獄'！$語句='??? – AbraCadaver

@AbraCadaver的！最近被添加了，所以它不是原因。 –

$stmt = $mysqli->prepare('INSERT INTO users (id, firstname, lastname) VALUES ("", ?, ?)');

中刪除從!的$stmt和你錯過)關閉VALUES
