我正在尝试使用PDO和预准备语句进行简单插入,但它不会插入数据,返回错误或其他任何内容。日志也是空的。这是正在执行但什么都不做的代码。值不为空。
try {
$query = $this->db_handler->prepare('INSERT INTO submissions (firstname, lastname, email, phone, mailinglist) VALUES (:firstname, :lastname, :email, :phone, :mailinglist);');
$query->bindParam(':firstname', $values['firstname']);
$query->bindParam(':lastname', $values['lastname']);
$query->bindParam(':email', $values['email']);
$query->bindParam(':phone', $values['phone']);
$query->bindParam(':mailinglist', $values['mailinglist']);
$query->execute();
} catch (PDOException $e) {
echo "DB error: " . $e->getMessage();
}
奇怪的是,这段代码运行正常,它在每个请求的前一个代码之前执行:
try {
$this->exec("CREATE DATABASE IF NOT EXISTS $this->db_name;");
$this->exec("USE $this->db_name;");
$this->exec("CREATE TABLE IF NOT EXISTS $this->table_name (
id INT(10) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
firstname VARCHAR(50) NOT NULL,
lastname VARCHAR(50) NOT NULL,
email VARCHAR(50) NOT NULL,
phone VARCHAR(12) NOT NULL,
mailinglist BOOLEAN NOT NULL,
submitdate TIMESTAMP
);");
} catch (PDOException $e) {
echo "DB error: " . $e->getMessage();
}
答案 0 :(得分:1)
正如MarcB在评论中指出的那样,我没有在PDO中启用例外。在实例化PDO实例后使用db_handler->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
显示查询出错。
