[mcj]给WordPress文章中的外部链接添加图标-马春杰杰

看下效果：

在这里，我们在之前go跳转的基础上进行修改，修改为：

//文章内外链添加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)){
                $content=str_replace("<a href=\"$val\"", "<i class='fa fa-external-link' style='color:#45b6f8'  aria-hidden='true'></i><a href=\"".home_url()."/go/?url=$val\" ",$content);
            }
        }
    }
 return $content;
}
add_filter('the_content','the_content_nofollow',999);

//文章内外链添加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)){

$content=str_replace("<a href=\"$val\"", "<i class='fa fa-external-link' style='color:#45b6f8' aria-hidden='true'></i><a href=\"".home_url()."/go/?url=$val\" ",$content);

}

return $content;

}

add_filter('the_content','the_content_nofollow',999);

保存即可，效果如下：
