前几天（差不多10天了吧，这文囧的可以……）写了《快速插入优酷视频改为 iframe 方式兼容移动设备》后，很多朋友评论说一律使用 Iframe 方式插入搜索引擎无法收录视频，对于偶尔插入分享视频的朋友来说无所谓，但如果是视频分享网站就不好了，毕竟你的内容核心是视频，而搜索引擎无法收录视频那还是很影响网站权重的。

那么就再 YY 一下（网上应该有很多类似教程了），我共享一下帮一个朋友做主题时写的这功能的代码吧，我用以前收藏的移动端判断函数来实现根据使用环境决定使用 embed 还是 iframe。

懒得具体说明了，直接上代码吧，里面有注释：另外这次的代码我特意修改做了兼容，支持任何语言的 WordPress

代码实现 PC 端 embed 方式移动端 iframe 方式快速插入优酷视频功能

1. 在 functions.php 插入以下代码（有些代码[如判断是否mobile]收录自搜索，源自哪里已无从考证——好吧，我忘了，如果你是原创作者请联系我）
【注：凡是加入主题的 functions.php 里面的代码都要放在 <php ?> 里面】

	$is_mobile = false;
	foreach ($mobile_agents as $device) {
		if (stristr($user_agent, $device)) {
			$is_mobile = true;
			break;
		}
	}
	return $is_mobile;
}

	wp_embed_register_handler( 'youku_iframe', '#http://v.youku.com/v_show/id_(.*?).html#i', 'wp_iframe_handler_youku' );

2. 用法：直接把优酷视频地址粘贴到文章内容里面，注意要独占一行

继续玩手机去~最近刷机刷狂了~

哦，我喜欢上那些带 HALO 的 ROM 了……

2013.7.22 更新：在评论中，大发提醒 WordPress 已经内置了移动设备判断函数 wp_is_mobile()，这是 WordPress 3.4 增加的，我没注意，所以代码可以精简成：

//// 如果 WordPress 不是中文版，增加优酷视频自动插入 Modify by zwwooooo | zww.me
if (get_bloginfo('language') != 'zh-CN') {
	function wp_embed_handler_youku( $matches, $attr, $url, $rawattr ) {

		if ( !empty($rawattr['width']) && !empty($rawattr['height']) ) {
			$width  = (int) $rawattr['width'];
			$height = (int) $rawattr['height'];
		} else {
			list( $width, $height ) = wp_expand_dimensions( 480, 400, $attr['width'], $attr['height'] );
		}
	  $embed = sprintf(
	    '<embed src="http://player.youku.com/player.php/sid/%1$s/v.swf" allowFullScreen="true" quality="high" width="'. esc_attr($width) .'" height="'. esc_attr($height) .'" align="middle" allowScriptAccess="always" type="application/x-shockwave-flash"></embed>',
	    esc_attr( $matches['video_id'] ) );

	  return apply_filters( 'embed_youku', $embed, $matches, $attr, $url, $rawattr );
	}
	wp_embed_register_handler( 'youku', 
	  '#https?://v\.youku\.com/v_show/id_(?<video_id>[a-z0-9_=\-]+)#i', 
	  'wp_embed_handler_youku' );
}

	//// 如果 WordPress 是中文版，移除原来的 youku 视频代码自动插入
	if (get_bloginfo('language')==='zh-CN')
		wp_embed_unregister_handler( 'youku' );

	//// 增加 iframe 方式的视频调用
	function wp_iframe_handler_youku( $matches, $attr, $url, $rawattr ) {
		// If the user supplied a fixed width AND height, use it
		if ( !empty($rawattr['width']) && !empty($rawattr['height']) ) {
			$width  = (int) $rawattr['width'];
			$height = (int) $rawattr['height'];
		} else {
			list( $width, $height ) = wp_expand_dimensions( 480, 400, $attr['width'], $attr['height'] );
		}
		$iframe = '<iframe width='. esc_attr($width) .' height='. esc_attr($height) .' src="http://player.youku.com/embed/'. esc_attr($matches[1]) .'" frameborder=0 allowfullscreen></iframe>';
		return apply_filters( 'iframe_youku', $iframe, $matches, $attr, $url, $ramattr );
	}
	wp_embed_register_handler( 'youku_iframe', '#http://v.youku.com/v_show/id_(.*?).html#i', 'wp_iframe_handler_youku' );
}

OK，WordPress 真是无孔不入啊，牛x到很多人都不用了转用其他偏门或者小型的博客系统——这神马逻辑？
