一、教程开始

  • 在你的WordPress网站根目录下新建文件go.php，输入以下代码并保存上传
  • 注意修改你的logo链接和回到主页链接
  • <?php
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
 
@session_start();
$t_url = !empty($_SESSION['GOLINK']) ? $_SESSION['GOLINK'] : preg_replace('/^url=(.*)$/i', '$1', $_SERVER["QUERY_STRING"]);
//数据处理
if (!empty($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);
    }
    //防止xss
    $t_url =  htmlspecialchars($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'];
}

    二、主题调用

    • 需要在主题中将go跳转的代码引入进来，添加在主题的/wp/themes/你的主题/ function.php文件中 
       
/**
* WordPress外链新窗口打开并使用php页面go跳转
*/
function the_content_nofollow($content)
{
        preg_match_all('/<a(.*?)href="(.*?)"(.*?)>/',$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.php?url=$val\" ",$content);
        }
        }
        }
        return $content;
}
add_filter('the_content','the_content_nofollow',999);
