基本上我可以使用它創建一條記錄,但它不會自動更新我的ID列以允許新記錄。我需要添加一個表達式來更新計數器嗎?還是有一個按鈕或開關使用phpmyadmin自動創建提交新ID?無法在MySQL中添加新記錄
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "message";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "INSERT INTO adminmessages (UserName, Message, Score)
VALUES ('SammyWest', 'Test1', '100')";
// use exec() because no results are returned
$conn->exec($sql);
echo "New record created successfully";
}
catch(PDOException $e)
{
echo $sql . "<br>" . $e->getMessage();
}
$conn = null;
?>
