纯代码实现WordPress主题添加倒计时功能[wordpress教程]

有些WordPress搭建的站点会发布一些限时活动或者限时的营销，仅仅在页面写上结束日期并不是很明了，因为搜索引擎上的内容会一直存在，所以可能会给某些访客造成误导，今天技术宅给大家带来的是纯代码实现WordPress主题添加倒计时功能！

其实很简单，就是给当前主题添加一段JS代码和一段函数即可轻松实现！

JS代码

将以下JS代码片段复制并保存为countdownjs.js，然后复制到主题当前目录下的js目录下：

function getAdd(time){
 
if(time<10){
 
return "0"+time;
 
}else{
 
return time;
 
}
 
}
 
var interval = 1000;
 
function ShowCountDown(year,month,day,hourd,minuted){
 
var now = new Date();
 
var endDate = new Date(year, month-1, day, hourd, minuted);
 
var leftTime = endDate.getTime() - now.getTime();
 
var leftsecond = parseInt(leftTime/1000);
 
var day = Math.floor(leftsecond/(60*60*24));
 
day = day < 0 ? 0 : day;
 
var hour = Math.floor((leftsecond-day*24*60*60)/3600);
 
hour = hour < 0 ? 0 : hour;
 
var minute = Math.floor((leftsecond-day*24*60*60-hour*3600)/60);
 
minute = minute < 0 ? 0 : minute;
 
var second = Math.floor(leftsecond-day*24*60*60-hour*3600-minute*60);
 
second = second < 0 ? 0 : second; var getDay = getAdd(day); var getHour = getAdd(hour); var getMinute = getAdd(minute); var getSecond = getAdd(second); if(endDate > now){
 
document.getElementById('time').innerHTML = '活动倒计时：';
 
document.getElementById('day').innerHTML = getDay +'天';
 
document.getElementById('hour').innerHTML = getHour +'时';
 
document.getElementById('min').innerHTML = getMinute +'分';
 
document.getElementById('sec').innerHTML = getSecond +'秒';
 
}else{
 
document.getElementById('countdown').innerHTML= '本次活动已经结束'
 
}
 
}      

PHP代码

将以下PHP代码复制到主题的functions.php中

function countdown($atts, $content=null) {
 
extract(shortcode_atts(array("time" => ''), $atts));
 
date_default_timezone_set('PRC');
 
$endtime=strtotime($time);
 
$nowtime=time();
 
global $endtimes;
 
$endtimes = str_replace(array("-"," ",":"),",",$time);
 
if($endtime>$nowtime){
 
return '
 
<div id="countdown">
 
<span id="time"></span>
 
<span id="day"></span>
 
<span id="hour"></span>
 
<span id="min"></span>
 
<span id="sec"></span>
 
</div>
 
';
 
}else{
 
return '本次活动已经结束';
 
}
 
}
 
function countdown_js() {
 
global $endtimes;
 
echo '<script>window.setInterval(function(){ShowCountDown('.$endtimes.');}, interval);</script>'."n";
 
}
 
add_shortcode('countdown', 'countdown');
 
add_action('wp_footer', 'countdown_js');
 
wp_register_script( 'countdown_js', get_template_directory_uri() . '/js/countdownjs.js', array(), '1.0', false );
 
wp_enqueue_script( 'countdown_js' );

代码调用

在需要显示倒计时的文章内容中添加以下代码即可，日期按照代码中的格式修改即可：

因为技术宅没有添加CSS代码，所以需要美化的自行添加CSS代码！
