redirect problem using HTTP_REFERER

[mat1987]

Hi,

 

I'm using this code to redirect visitors who are coming from another site (clicking on my ad on that site) to a page in my site where I can track them:

$referrer = $_SERVER['HTTP_REFERER'];
    if ( strstr($referrer, '://example.com/shop') )
       print ('<meta http-equiv="refresh" content="0; URL=http://www.mysite.com/1.php">');

The problem is that, by this code I can only redirect those who are coming from example.com/shop, but I need to redirect visitors coming from any sub directory or subdomain from example.com, not only a specific url in example.com

 

Is there any solution?

 

 

Thanks

You bet there is. Many, in fact.

 

What have you tried yourself?

actually none. I'm not a pro

just need to detect the root domain and if the root domain is example.com, then do the redirect, regardless of any subdomains or subdirectories like blog.example.com or example.com/blog

Have you tried just searching for "example.com"?

You may also want to check out PHP's parse_url() function:

You can accomplish this by using a .htaccess file in the root directory and let apache handle it rather than php. I am not completely versed in .htaccess, but I have used it in the past to develop a redirect site similar to bit.ly. A Google search on .htaccess should get you in the right direction. I apologize I cannot give you concrete examples, but .htaccess came to mind when I read this post.

 

You can have the .htaccess file put the referrer information into url variables so they can be used in a $_GET method in your php function when the .htaccess file redirects.

 

Hope I can at least get you in the right direction. Good Luck!

Thanks a lot guys.

The final working code is:

$referrer = $_SERVER['HTTP_REFERER'];
if (preg_match('~example\.com$~', parse_url($referrer, PHP_URL_HOST))) {
       print ('<meta http-equiv="refresh" content="0; URL=http://www.mysite.com/1.php">');
}
