How to only accept absolute url submission?

Hi,

I have a link submission website in php (Pligg) and I wonder how to force a user to only submit the absolute url -for example http://example.com and not http://example.com/page or http://subdir.example.com.

Grateful for any help. Thanks.

 

if ($_POST['submit'] && $_SERVER['REQUEST_URI'] == '/something') {
//exec code
}else {
//bad
}

PHP:

 

<?php
if(isset($_GET['url'])){
    $url = parse_url($_GET['url']);
    if($url['path'] != '"){
        echo "invalid";
    }else{
        echo "valid";
    }
}
?>

PHP:

save this as check.php and ifyou open yourdomain.com/check.php?url=<url> it will say valid or invalid

 

Hello, Thanks for the replies!

Ok, how can I now make it work for/together with the script I am using? My PHP knowledge is really bad..

Thanks.

 

Now that would totally depend on the script you are using. PM me with details maybe i could help/

 

Ok, PM sent, thanks.
