wordpress中用 iframe 方式插入优酷视频 兼容移动设备

现在的 WordPress 中文版内置了“使用 WordPress 的 Embed 功能快速插入优酷视频”的功能：只要在写文章时，独占一行粘贴优酷视频地址就可以自动调用次视频。

例如：我在下一行独占一行插入 http://v.youku.com/v_show/id_XNTgxNzI3MDcy.html 这个优酷视频地址，就可以自动调用优酷视频了。

但是这是用 Embed 的，PC端没问题，手机浏览器因为不支持 Flash 所以是无法显示和播放视频的，而现在提供的 iframe 方式插入的视频就支持手机。

下面说说如何实现：

『使用 WordPress 的 Embed 功能快速插入优酷视频』改为以 iframe 方式调用的方法

有点绕口，?濉Ｆ涫岛芗虻?br /> 1. 确定所用 WordPress 是中文版（好像其他语言版本也行，如果有错误提示就把 wp_embed_unregister_handler( 'youku' ); 删除即可）
2. 就是把下面的代码扔进所用主题的 functions.php 里面（注意：代码要放在 里面）

/**
 * 『使用 WordPress 的 Embed 功能快速插入优酷视频』改为以 iframe 方式调用
 *  by zwwooooo | zww.me
 */
// 移除原来 WordPress 中文版内置的“使用 WordPress 的 Embed 功能快速插入优酷视频”
wp_embed_unregister_handler( 'youku' );
// 改用 iframe 方式
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'];
    } else {
        list( $width, $height ) = wp_expand_dimensions( 480, 400, $attr['width'], $attr['height'] );
    }
    $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' );

PS：其他视频网站可以照葫芦画瓢改下代码就行了。


PC端embed方式移动端iframe方式快速插入优酷视频两个方法

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 里面】

    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……

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：

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
