external links without http?

i have a form where many people simply forget to put http:// while submitting their site. it doesnt redirect.

when i create a link it simply points to local file and doesnt work.

what is the solution to this?

 

You need to use an if/else statement in PHP or even Javascript.

heres PHP:

if ((!strstr($url,'http://')) && (!strstr($url,'https://'))){
    $url = 'http://'.$url;
    } else {
    //do nothing?  $url = $url;
    }

PHP:

 

thanks +rep

 

<input name="url" value="http://" />
