当使用CURRENT_TIMESTAMP时，将表单数据插入mysql失败 - inserting form data into mysql fails when using CURRENT_TIMESTAMP?

inserting form data into mysql fails when using CURRENT_TIMESTAMP?

我试图从我的表格插入数据到mysql，这工作得很好，但当我添加一个'date_created'列与时间戳和CURRENT_TIMESTAMP它导致sql查询失败?

谁能告诉我这是为什么?

下面是我的mysql函数:

<?php ob_start(); 
// CONNECT TO THE DATABASE
    require('../includes/_config/connection.php');
// LOAD FUNCTIONS
    require('../includes/functions.php');

$username = $_POST['username'];
$password = $_POST['password'];
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$email = $_POST['email'];
$age = $_POST['age'];
$gender = $_POST['gender'];
$country = $_POST['country'];


$query="INSERT INTO ptb_registrations (ID,
username,
password,
firstname,
lastname,
email,
age,
gender,
country
 )
VALUES('NULL',
'".$username."',
'".$password."',
'".$firstname."',
'".$lastname."',
'".$email."',
'".$age."',
'".$gender."',
'".$country."'
)";
mysql_query($query) or die ('Error updating database');
?>

<?php include ('send_email/reg_email.php'); ?>
<? ob_flush(); ?>

您可以尝试将日期/时间列添加到表中。然后再次尝试插入查询，看看是否有效:

   ALTER TABLE table_name ADD timeanddate_colname TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP;

如果你的列不是时间戳，那么修改你的表

  ALTER TABLE table_name ADD DEFAULT (CURRENT_TIMESTAMP) FOR [Cold2]

或者在其他情况下，如果您可以通过CURDATE()或NOW()添加current_date
