我有这个倒数计时器的代码。它基本上是 PHP/Javascript 倒数计时器的组合,它将$end_date
从 Mysql 表/字段中获取。
问题是它会在某个时间自动停止(这是不需要的)。
例如:我在mysql数据库中设置$end_date
为。September 19 2013 11:30:00 AM GMT
倒计时开始并且工作正常,并开始倒计时。但是,当倒数计时器到达September 19 2013 13:00:00 PM GMT
时,它将停止并显示 Times Up 消息!$end_date
基本上,一旦更改为,它将停止工作或倒计时13:00:00 PM
。
我在我的代码中看不到任何会导致此问题的内容。除了这一行:
if ($now < $exp_date ) {
?>
但同样,这一行只告诉脚本何时开始计数,据我所知,只要计时器没有达到$end_date
. 还是我错过了什么?
这是我的代码:
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
?>
<?php date_default_timezone_set('GMT'); ?>
<?php
session_start();
// Run a select query to get my letest 6 items
// Connect to the MySQL database
include "config/connect.php";
$dynamicList = "";
$sql = "SELECT * FROM item ORDER BY id";
$query = mysqli_query($db_conx, $sql);
$productCount = mysqli_num_rows($query); // count the output amount
if ($productCount > 0) {
while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){
$id = $row["id"];
$product_name = $row["product_name"];
$date_added = date("Y-m-d", strtotime($row["date_added"]));
$end_date = date("F d Y H:i:s A T", strtotime($row["end_date"]));
$price = $row["price"];
$dynamicList .= '<div>' . $end_date . '
</div>';
}
} else {
$dynamicList = "No Records";
}
?>
<?php
$date = $end_date;
$exp_date = strtotime($date);
$now = time();
if ($now < $exp_date ) {
?>
<script>
// Count down milliseconds = server_end - server_now = client_end - client_now
var server_end = <?php echo $exp_date; ?> * 1000;
var server_now = <?php echo time(); ?> * 1000;
var client_now = new Date().getTime();
var end = server_end - server_now + client_now; // this is the real end time
var _second = 1000;
var _minute = _second * 60;
var _hour = _minute * 60;
var _day = _hour *24
var timer;
function showRemaining()
{
var now = new Date();
var distance = end - now;
if (distance < 0 ) {
clearInterval( timer );
document.getElementById('countdown').innerHTML = 'EXPIRED!';
return;
}
var days = Math.floor(distance / _day);
var hours = Math.floor( (distance % _day ) / _hour );
var minutes = Math.floor( (distance % _hour) / _minute );
var seconds = Math.floor( (distance % _minute) / _second );
var countdown = document.getElementById('countdown');
countdown.innerHTML = '';
if (days) {
countdown.innerHTML += 'Days: ' + days + '<br />';
}
countdown.innerHTML += 'Hours: ' + hours+ '<br />';
countdown.innerHTML += 'Minutes: ' + minutes+ '<br />';
countdown.innerHTML += 'Seconds: ' + seconds+ '<br />';
}
timer = setInterval(showRemaining, 1000);
</script>
<?php
} else {
echo "Times Up";
}
?>
<div id="countdown"></div>
任何帮助将不胜感激。
