Question

我有一个奇怪的问题，我已经在我建立的几个网站上，但我无法找到问题，它似乎很简单，当用户登录到网站时我更新了列的时间戳＆＃34; member_login＆＃34;对NOW（）工作得很好，唯一的问题是，它还会更新＆＃34; member_joined＆＃34;列与＆＃34; member_login＆＃34;完全相同时间戳，但代码中的 NOWHERE 我告诉它更新＆＃34; member_joined＆＃34;柱！整个登录脚本非常简单：

的login.php

<?php

session_start();
include('includes/db_connection.php');
include('includes/functions.php');

?>

<?php

if (isset($_POST['submitLogin'])) {

    $username = trim(strtolower($_POST['username']));
    $password = trim(strtolower($_POST['password']));

    if (empty($username) || empty($password)) {
        include('includes/header.php');
        include('includes/navbar.php');
        stderr('Please fill in <b>both</b> login fields.');
        include('includes/footer.php');
    }

    $memberInfo = DB::getInstance()->selectOne(
        '
        SELECT  DISTINCT member_username, member_fees_paid, member_fees_paid_on
        FROM    `membership`
        WHERE   `member_username` = :member_username
        AND     `member_password` = :member_password',
        [
            'member_username' => $username,
            'member_password' => $password
        ]
    );

    if (!count($memberInfo)) {

        include('includes/header.php');
        include('includes/navbar.php');
        stderr('Sorry, username <b>and/or</b> password combination not found.');
        include('includes/footer.php');

    } else {

        $_SESSION['member'] = $username;        

        if ($memberInfo['member_fees_paid'] === 'N') {
            $payedOn = new \DateTime($memberInfo['member_fees_paid_on']);
            $payedOn->setTime(0, 0, 0);
            $monthAgo = new \DateTime('28 days ago');
            $monthAgo->setTime(0, 0, 0);
            if ($monthAgo > $payedOn) {
                try {
                    DB::getInstance()->execute(
                        '
                        UPDATE  `membership`
                        SET     `member_fees_paid`= \'N\'
                        WHERE   `member_username` = :member_username
                        AND     `member_password` = :member_password',
                        [
                            'member_username' => $username,
                            'member_password' => $password
                        ]
                    );
                    header('Location: my-account.php');

                }
            }
        }

        try {

            DB::getInstance()->execute(
                '
                UPDATE  `membership`
                SET     `member_login` = NOW()

成功登录后，我们只需更新＆＃34; member_login＆＃34;的时间戳。并重定向到＆＃34; my-account.php＆＃34;页面，它应该工作，但它不断更新＆＃34; member_joined＆＃34; colums与＆＃34; member_login＆＃34;相同我无法弄清楚为什么这样做，任何帮助将不胜感激！

Answer 1

如果您的列member_joined的类型为timestamp，您可能需要检查更新CURRENT_TIMESTAMP是否未被使用 - 您可以在数据库读取器（例如phpMyAdmin）中进行检查， SequalPro，Heidi等。

这会自动将日期戳更新为当前日期/时间。
