日期值不正确：第 1 行 'birthday' 列的 ''

Question

我是 PHP 的新手，我正在尝试创建一个注册表单，我正在获取

"Incorrect date value: '' for column 'birthday' at row 1

错误。起初我以为这是查询，但我修复了它，但我仍然收到错误，它只是一个不同的列。找遍了，还是没有，求助

我的add.php代码

<?=
$first_name = ( !empty($_GET['f-name']) ) ? $_GET['f-name']: "";
$last_name = ( !empty($_GET['l-name']) ) ? $_GET['l-name']: "";
$email = ( !empty($_GET['email']) ) ? $_GET['email']: "";
$password = ( !empty($_GET['psw']) ) ? $_GET['psw']: "";
$birthday = ( !empty($_GET['age']) ) ? $_GET['age']: "";
$phone = ( !empty($_GET['phone']) ) ? $_GET['phone']: "";
$ministry = ( !empty($_GET['ministry']) ) ? $_GET['ministry']: "";



$query = "INSERT INTO `member` (`first_name`, `last_name`, `email`, `password`, `birthday`, `phone`, `ministry`) VALUES ('$first_name', '$last_name', '$email', '$password', '$birthday', '$phone', '$ministry')";
$hostname = 'localhost';
$db_name = 'catacumba';
$username = 'root';
$password = 'mysql';

try{

$db = new mysqli($hostname, $username, $password, $db_name);

if ($db->query($query) === TRUE) {
echo "Record Created";
} else {
echo "Error Creating record: " . $db->error;
}

//close the connection to DB
$db->close();


}catch(Exception $e)
{
$error_message = $e->getMessage();
echo "<p>Error message: $error_message </p>";
}

?>

我的create_account.php表格

<form class="modal-content" action="Add.php" method="post">

Answer 1

列值不正确是一个MySQL错误与您为[=10=选择的列数据类型相关].

如果您插入的 birthday 值与 MySQL date 数据类型 2021-02-22 17:03:24 有任何不同，您将收到此列类型错误。

确保您要插入的生日的格式为 YYYY-MM-DD HH:MM:SS。

至于使用mysqli，不要。请改用 PDO。
