Now more and more blogs use external links to jump pages, which is said to prevent external links from affecting the weight of their own WordPress blogs and causing search engines to drop their weight. Today , I will share with you a beautiful WordPress jump GO style, which supports responsive layout.
WordPress External Link Jump Style
WordPress external link jump code
Save the following code as go.php and upload it to the root directory of WordPress (same level as the wp-admin folder). And replace the information that needs to be modified by yourself.
<?php
if(strlen($_SERVER['REQUEST_URI']) > 255 ||
strpos($_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;
}
//Get the complete incoming data through QUERY_STRING, and then get all the values after url=, better compatibility $t_url = preg_replace('/^url=(.*)$/i','$1',$_SERVER[ "QUERY_STRING"]);
//Data processing if(!empty($t_url)) {
//Judge whether the value is encrypted if ($t_url == base64_encode(base64_decode($t_url))) {
$t_url = base64_decode($t_url);
}
//Url verification and judgment on the value preg_match('/^(http|https|thunder|qqdl|ed2k|Flashget|qbrowser):\/\//i',$t_url,$matches);
if ($matches) {
$url=$t_url;
$title='The page is loading, please wait...';
} else {
preg_match('/\./i', $t_url, $matche);
if ($matches) {
$url='http://'.$t_url;
$title='The page is loading, please wait...';
} else {
$url = 'http://'.$_SERVER['HTTP_HOST'];
$title='Parameter error, returning to home page...';
}
}
} else {
$title = 'The parameter is missing, returning to the home page...';
$url = 'http://'.$_SERVER['HTTP_HOST'];
}
?>

Add the following code anywhere in functions.php to realize the GO jump effect for all external links.
add_filter('the_content', 'the_content_nofollow', 999);
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;
}
Friendly reminder: If the functions.php file is updated in the blog theme, the second code needs to be uploaded again.
