Hello  
what is wrong here? i want to do one action if on the url theres any anchor=…  
example… i have a link to index.php  
and i have another link to index.php?anchor=roger  
in one link i don’t want to do nothing  
on the second i want to echo roger.  
What is wrong in

```php
if($_GET['anchor'] != null) {

```

?  
And by the way… how to use this GET command if it’s inside an iframe? It’s not getting the url from the top page ☹  
Thanks in advance
