WordPress判断PC端和移动端并显示不同内容的方法

判断用户PC电脑端和手机移动端，不同客户端显示不同的内容是WordPress必不可少的功能，通过php通过http_user_agent即可判断用户的客户端。

今天分享PC电脑端和移动手机端显示不同内容的方法：

一：在 functions.php 中加入如下代码：
 

// 判断PC端
function is_pc() {
                $user_agent = $_SERVER['HTTP_USER_AGENT'];
                $mobile_browser = Array(
                                "mqqbrowser", //手机QQ浏览器
                                "opera mobi", //手机opera
                                "juc","iuc",//uc浏览器
                                "fennec","ios","applewebKit/420","applewebkit/525","applewebkit/532","ipad","iphone","ipaq","ipod",
                                "iemobile", "windows ce",//windows phone
                                "240x320","480x640","acer","android","anywhereyougo.com","asus","audio","blackberry","blazer","coolpad" ,"dopod", "etouch", "hitachi","htc","huawei", "jbrowser", "lenovo","lg","lg-","lge-","lge", "mobi","moto","nokia","phone","samsung","sony","symbian","tablet","tianyu","wap","xda","xde","zte"
                );
                $is_mobile = ture;
                foreach ($mobile_browser as $device) {
                                if (stristr($user_agent, $device)) {
                                               $is_mobile = false;
                                                break;
                                }
                }
                return $is_mobile;
}
// 判断手机端
function is_mobile() {
               $user_agent = $_SERVER['HTTP_USER_AGENT'];
                $mobile_browser = Array(
                                "mqqbrowser", //手机QQ浏览器
                                "opera mobi", //手机opera
                                "juc","iuc",//uc浏览器
                                "fennec","ios","applewebKit/420","applewebkit/525","applewebkit/532","ipad","iphone","ipaq","ipod",
                                "iemobile", "windows ce",//windows phone
                                "240x320","480x640","acer","android","anywhereyougo.com","asus","audio","blackberry","blazer","coolpad" ,"dopod", "etouch", "hitachi","htc","huawei", "jbrowser", "lenovo","lg","lg-","lge-","lge", "mobi","moto","nokia","phone","samsung","sony","symbian","tablet","tianyu","wap","xda","xde","zte"
                );
                $is_mobile = false;
                foreach ($mobile_browser as $device) {
                                if (stristr($user_agent, $device)) {
                                                $is_mobile = ture;
                                                break;
                                }
                }
                return $is_mobile;
}

二：WordPress模板中调用

在WP模板中调用，如 index.php、footer.php、single.php 等，调用方式：

1、在PC电脑端显示，移动端不显示

<?php if (is_pc() ): ?>

<div>

        <p>我在PC电脑端显示</p>

</div>

<?php endif ;?>

2、在移动端显示，PC端不显示

<?php if (is_mobile() ): ?>

<div>

<p>我在移动端显示，不在PC端显示</p>

</div>

<?php endif ;?>

综上，第一步在主题下的functions.php文件中插入代码，然后再WordPress主题模板中调用即可。

总结：

该代码的主要解决的问题自动判断用户的客户端，然后元素模板站长根据不同的客户端来展示不同的内容。

使用is_pc()这段代码，该代码会自动判断访客客户端是否是PC，如果是PC则显示，不是PC则不显示；

使用is_mobile()这段代码，该代码会自动判断访客客户端是否是移动端，如果是移动端则显示，不是移动端则不显示；
