[RESOLVED] regular expression

[mikesch]

Hi,

I need to check that $_POST[urltitle] is not all whitespace. How would I code that?

This is what I've got so far, but the problem is that $error gets set to true always, even when the $_POST[title] is valid and should be accepted.

  if (!eregi("^[[:alnum:]]{1}$",stripslashes(ltrim($_POST[title])))){$error=true;}

Thanks.

Mike

if you are simply checking for all whitespace then you do not need regex:

if (trim($_POST['title']) == '') {$error = true;}
else {$error = false;}

Thank you very much. It works. 🙂
