WordPress判断手机移动设备的函数 wp_is_mobile 所在的位置在 /wp-includes/vars.php
这是一段php通用的判断移动浏览器的函数,原理比较简单,就是判断浏览器返回的user_agent,条件包括手机系统、品牌和窗口大小。
以WordPress为例,在主题的 functions.php 内加上如下代码,目前已包含常见移动浏览器的useragent,基本上可以涵盖可能会用手机上网的用户群了。
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 = true; break; } } return $is_mobile; }
然后在主题任意模板如顶部加上如下判断:
<?php if (is_mobile() ): ?> //怎样怎样..(这里可以添加一个mobile.css,如<link rel="stylesheet" type="text/css" media="all" href="<?php echo get_template_directory_uri(); ?>/mobile.css" />) <?php endif ;?>
还需要注意的一点:不管是单独的WordPress主题还是自适应主题,都需要在头部<head>将添加下面meta,否者可能导致手机显示字体过小等问题。
<meta name="viewport" content="width=device-width"/>
