[SOLVED] making sure http:// is included.

[whelpton]

Im making a form processor that lets people submit links for use on a public profile.

 

I was wondering if there was any way of modifying this code:

$f = fopen("/home/alport/public_html/".$_SESSION['s_username']."/text/link1.txt", 'w');
fwrite($f, strip_tags($_POST['save']));
fclose($f);

To check for "http://" when it is submitted and if it is not there, then add it automatically?

 

Thanks alot

if(strpos('http://', $var_containing_url) === false) {

    //string does not contain http://

}

 

 

 

But, you will probably want to make sure that the URL starts with http:// in which case you could do if(!strpos(....) === 0) { /*doesn't start with it */ }

 

 

Is the URL in the middle of other content?  If so, you will have to use regular expressions.

$url .= substr($url, 0, 7) != 'http://' ? 'http://' : null;

Thanks for the two replies, but I am an absoloute beginner at php and I have no idea of how to integrate that into my existing code, can someone show me how to?

Then you need to read through the Language Reference chapter of the manual. It's required reading for anyone. No excuse.
