Question

I have a comment system that allows auto linking of url. I am using cakephp but the solution is more just PHP. here is what is happening.

if the user enters fully qualified url with http:// or https:// everything is fine.
but if they enter www.scoobydoobydoo.com it turns into http://cool-domain.com/www.scoobydoobydoo.com. basically cakephp understands that http|https is an external url so it works with http|https not otherwise.

My idea was to do some kind of str stuff on the url and get it to insert the http if not present. unfortunately whatever i try only makes it worse. I am noob 🙂 any help / pointer is appreciated.

thanks

EDIT: posting solution snippet. may not be the best but thanks to answer at least I have something.

<?php
        $proto_scheme = parse_url($webAddress,PHP_URL_SCHEME);
    if((!stristr($proto_scheme,'http')) || (!stristr($proto_scheme,'http'))){
        $webAddress = 'http://'.$webAddress;
    }
?>

Try the parse_url function: http://php.net/manual/en/function.parse-url.php

I think this will help you.
