I need to redirect a user to a page but need to extract the anchor tag from the called url (to put it on the redirect url)  
I have try Router::getRequest()-\>getUri() but I don’t see the anchor tag in it.

What is the best way to extract the anchor tag from the called URL in cakePHP 4

thanks

What you are probably looking for is the HTTP referer header which points to the original URL the user was on before he clicked on the anchor tag.

```auto
$referer = $this->getRequest()->referer();

```

yes and no, in fact I have to add a GET parameter to that url, so I have to :  
1/ extract the anchor  
2/ add the parameter  
3/ re-add the anchor

adding the parameter after the anchor don’t work.

example : /mypage?param=1#anchor should become /mypage?param=1&param=2#anchor

also if the user come from google, It won’t work (but I am agree check that the host is mine is possible 🙂 )

thanks

I would recommend you look at [authentication/AuthenticationService.php at 2.x · cakephp/authentication · GitHub](https://github.com/cakephp/authentication/blob/2.x/src/AuthenticationService.php#L365) which does basically the same.

You need to encode your desired URL as a GET parameter (via `urlencode()`) so whatever logic you have in your redirected page can extract that urlencoded data and `urldecode()` it.

You can’t just put a whole URL without any encoding inside another URL.
