adding text if it does not exist

[natefanaro]

I am looking for something that will add http:// if it does not exist in a form. If it does exist, don't add http://

so

http://www.yahoo.com

would be changed to

http://www.yahoo.com

http://www.google.com

would not be changed at all.

I think that I would have to use regular expressions, or preg_replace. Any ideas?

Assuming that the text to check is $text:
<?
if(!preg_match(&quot;/http:\/\//i&quot;,$text)) {
$text=&quot;

http://&quot;

. $text;
}
?>

ok, it didn't work origionally but I played around enough to get it going. I think you added a period here: $text=&quot;

http://&quot;;

. $text; by mistake. Thank you very much for your help. here's a page that i whipped up. You can try it out if you would like.

<?
if ($submit){
if(!preg_match(&quot;/http:\/\//i&quot;,$text)) {
echo &quot;

http://$text&quot;;

} else {
echo &quot;$text&quot;;
}
} {
?>
<form action=&quot;testhttp.php&quot; method=&quot;post&quot;>
<input type=&quot;text&quot; name=&quot;text&quot;>
<input type=&quot;submit&quot; name=&quot;submit&quot; value=&quot;submit&quot;>
</form>
<?
}
?>

Nope, that was what I meant to type, but Tek Tips messed it up after I submitted it. It added a &quot;;&quot;--Probably because I had TGML on. This was what I meant:

<?
if(!preg_match(&quot;/http:\/\//i&quot;,$text)) {
$text=&quot;

http://&quot;

. $text;//no semicolon untill the end.
}
?>
