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。

给7B2主题加上外链自动跳转功能

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[0] ) {
$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'];
}
?>

<script type="text/javascript">
function alertSet(e) {
document.getElementById("js-alert-box").style.display = "block", document.getElementById("js-alert-head").innerHTML = e;
var t = 5,
n = document.getElementById("js-sec-circle");
document.getElementById("js-sec-text").innerHTML = t, setInterval(function() {
//禁止其他网站调用此跳转
//var MyHOST = new RegExp("<?php echo $_SERVER['HTTP_HOST']; ?>");
//if (!MyHOST.test(document.referrer)) {
// location.href="http://" + MyHOST;
//}
if (0 == 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=0; $i < count($matches); $i++)
			{
				$tag = $matches[$i][0];
				$tag2 = $matches[$i][0];
				$url = $matches[$i][0];
				$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。
