我已经在互联网上四处寻找，但未能解决这个问题。
我正在尝试通过此函数使用 PDO 将一行插入到 mySQL 表中
function newItem($name, $desc, $price, $catID){
echo $name . "\n";
echo $price . "\n";
echo $desc . "\n";
echo $catID . "\n";
$conn = self::connect();
//INSERT Order
$sql = "INSERT INTO catalogue (Name, Price, CatID, Desc)
VALUES ('$name', $price, $catID, '$desc')";
// use exec() because no results are returned
$conn->exec($sql);
}
当我这样做时，我得到这个错误:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'Desc) VALUES ('User', 0.00, 3, 'theUser')' at line 1' in C:\xampp\htdocs\classes\catalogue.php:65 Stack trace: #0 C:\xampp\htdocs\classes\catalogue.php(65): PDO->exec('INSERT INTO cat...') #1 C:\xampp\htdocs\classes\main.php(39): Catalogue->newItem('User', 'theUser', '0.00', '3') #2 {main} thrown in C:\xampp\htdocs\classes\catalogue.php on line 65
我可以确认 self::connect(); 方法有效，只有当我尝试将数据插入 Desc 列时才会出现问题。
我花了很多时间尝试解决这个问题，但是我对 PDO 的了解非常模糊......
谁能看出我哪里出错了？
