给7B2主题加上外链自动跳转功能
7B2主题默认是没有外链自动跳转功能的，这玩意要说有用吧，作用不大，要说没用吧，大家都这么加，所以跋涉者也给外链增加一个自动跳转。
是不是很漂亮的的，感谢缙哥哥分享的源码
第一步，建立一个go跳转文件
把下面的代码保存成index.php,在网站的根目录里新建一个go文件夹，然后把这个index.php上传到这个文件夹里
<?php /** * WordPress外链go跳转页面 - https://www.dujin.org/12762.html * @copyright (c) Emlog All Rights Reserved *///自定义跳转地址$cars = array(array("qcloud",'http://www.qcloud.com/redirect.php?redirect=1001&cps_key=8558139aea55e95d71f488081ba44577'),array("upyun",'https://www.upyun.com/league'),array("trustutn",'http://c.trustutn.org/s/aeink.com'),array("gfvps",'https://www.gfvps.cn/page.aspx?c=referral&u=9023'),array("360scan",'http://webscan.360.cn/index/checkwebsite/url/www.aeink.com')); if(strlen($_SERVER['REQUEST_URI']) > 384 || strpos($_SERVER['REQUEST_URI'], "eval(") || strpos($_SERVER['REQUEST_URI'], "base64")) {@header("HTTP/1.1 414 Request-URI Too Long");@header("Status: 414 Request-URI Too Long");@header("Connection: Close");@exit;}//通过QUERY_STRING取得完整的传入数据，然后取得url=之后的所有值，兼容性更好$t_url = htmlspecialchars(preg_replace('/^url=(.*)$/i','$1',$_SERVER["QUERY_STRING"])); //此处可以自定义一些特别的外链，不需要可以删除以下5行foreach($cars as $k=>$val){if($t_url==$val[] ) {$t_url = $val[1];$t_vip = 1;}} //数据处理if(!empty($t_url)) {//判断取值是否加密if ($t_url == base64_encode(base64_decode($t_url))) {$t_url = base64_decode($t_url);}//对取值进行网址校验和判断preg_match('/^(http|https|thunder|qqdl|ed2k|Flashget|qbrowser):\/\//i',$t_url,$matches);if($matches){$url=$t_url;$title='页面加载中,请稍候...';} else {preg_match('/\./i',$t_url,$matche);if($matche){$url='http://'.$t_url;$title='页面加载中,请稍候...';} else {$url = 'http://'.$_SERVER['HTTP_HOST'];$title='参数错误，正在返回首页...';}}} else {$title = '参数缺失，正在返回首页...';$url = 'http://'.$_SERVER['HTTP_HOST'];}?><html><!-- @name:aeink goto @description:AE博客跳转页面 @author:墨渊 @time:2017-09-22 @copyright:AE博客&墨渊 @author url:http://www.aeink.com/791.html @ps:你想删我也拦不住看你自觉性吧！！ --><head><meta http-equiv="Content-Type" content="text/html;

?>");//if (!MyHOST.test(document.referrer)) {// location.href="http://" + MyHOST;//}if ( == t) location.href = "<?php echo $url;?>";else {t -= 1, document.getElementById("js-sec-text").innerHTML = t;var e = Math.round(t / 5 * 735);n.style.strokeDashoffset = e - 735}}, 970)}</script><script>alertSet("<?php echo $title;?>");</script></body></html>
第二步，在functions.php里添加如下代码
/** * WordPress外链新窗口打开并使用php页面go跳转 * https://www.dujin.org/12762.html */function the_content_nofollow($content){ preg_match_all('//',$content,$matches); if($matches){ foreach($matches[2] as $val){ if(strpos($val,'://')!==false && strpos($val,home_url())===false && !preg_match('/\.(jpg|jepg|png|ico|bmp|gif|tiff)/i',$val)){ $content=str_replace("href=\"$val\"", "href=\"".home_url()."/go/?url=$val\" ",$content); } } } return $content; } add_filter('the_content','the_content_nofollow',999);
第三步，添加新窗口自动打开并添加nofollow属性
现在打开文章里的链接是在原有窗口上打开的，我们一般要求是在新窗口打开，为了不让权重的流逝，我们还要加上nofollow标签，继续在functions.php添加如下代码：
/** * WordPress外链自动新窗口打开并添加nofollow属性 - 方法二 * https://www.dujin.org/12336.html */add_filter( 'the_content', 'cn_nf_url_parse'); function cn_nf_url_parse( $content ) { $regexp = "]*href=(\"??)([^\" >]*?)\\1[^>]*>"; if(preg_match_all("/$regexp/siU", $content, $matches, PREG_SET_ORDER)) { if( !empty($matches) ) { $srcUrl = get_option('siteurl'); for ($i=; $i < count($matches); $i++) { $tag = $matches[$i][]; $tag2 = $matches[$i][]; $url = $matches[$i][]; $noFollow = ''; $pattern = '/target\s*=\s*"\s*_blank\s*"/'; preg_match($pattern, $tag2, $match, PREG_OFFSET_CAPTURE); if( count($match) < 1 ) $noFollow .= ' target="_blank" '; $pattern = '/rel\s*=\s*"\s*[n|d]ofollow\s*"/'; preg_match($pattern, $tag2, $match, PREG_OFFSET_CAPTURE); if( count($match) < 1 ) $noFollow .= ' rel="nofollow" '; $pos = strpos($url,$srcUrl); if ($pos === false) { $tag = rtrim ($tag,'>'); $tag .= $noFollow.'>'; $content = str_replace($tag2,$tag,$content); } } } } $content = str_replace(']]>', ']]>', $content); return $content; }
至此，所有的工作都已经完成了，是不是很简单。
