请帮忙！我有一个用户页面设置并正确链接到我的数据库。我想要做的是为没有激活帐户的用户添加3小时的倒数计时器。我希望该计时器对于个人用户是唯一的，一旦他们注册他们的帐户就开始计数，当他们登录倒计时时，将显示在页面上。请问，任何人都可以帮我一个简单的代码来实现这个吗？非常感谢。
PS：我是代码编写的假人，因此我使用Dreamweaver来帮助我生成代码。
这是我的网页代码：
<?php require_once('Connections/TurboFund.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
if (PHP_VERSION < 6) {
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
}
$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}
if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "Received1")) {
$updateSQL = sprintf("UPDATE users SET AcceptedFrom1=%s WHERE UserID=%s",

mysql_select_db($database_TurboFund, $TurboFund);

答案 0 :(得分：0)
注册新用户时，您可以在用户表的字段中存储时间戳。你也可以使用mysql insert 触发器自动为你做这件事。
当用户登录时，您可以从当前时间戳中减去已注册的时间戳并显示在用户信息中心中。
您也可以使用JavaScript继续在用户仪表板中显示倒计时器，并使用interval或setTimeout。
已编辑：
在您的表格中设置时间戳，您可以简单地将值设置为您的字段，如下所示：
ALTER TABLE `schema`.`users`
CHANGE COLUMN `created` `created` DATETIME NOT NULL
DEFAULT CURRENT_TIMESTAMP ON Insert CURRENT_TIMESTAMP ;
注意：在mysql和php中获取时间戳有点不同。
当您尝试登录或当您的工作被解雇时，如果用户未完成注册步骤的时间超过3小时，您可以检查时间并删除用户。类似下面的 php 代码：
if($row["approved"]!=true)//check if user didn't finish registration steps
{
$timest = $row["created"];//you must getting $row info from user table
$registerTime = strtotime($timest);
$curentTime = time();
if(($curentTime-$registerTime) > 10800) { //(60*60*3) seconds
//Delelet your user
}
}
