Hi guys,

I just basically require a 'telephone' field on a form validated in the following way:

It only accepts whole numbers,
It allows for a space (eg 0161 123456)

Can anyone show me how this is done - thanks in advance. :)

basically, here's a really simple regex that will check for a 10 digit number, but it will allow for a space after the fourth digit only:
[code]
if (preg_match("|^[0-9]{4}([ ]?)[0-9]{6}$|", $number))
  echo "Valid!<br />\n";
else
  echo "Invalid!<br />\n";
[/code]

hope this helps
