Re: regex newbie question

Personally I prefer to use preg (perl regular expressions) if ( preg_match('/^[a-z0-9\s]+$/i', $field) ) { $field_valid = true; } -js David Pratt wrote:

Hoping someone can help with something probably quite simple I am using regex to validate user input this way:

        if (ereg ("^[a-zA-Z0-9\s]+$", $field)) {
            $field_validate = TRUE;
        }

I am trying to get the expression to accept upper or lower case letters and numbers and also allow spaces. It works when I test the expression at http://regexlib.com/RETester.aspx but I can't seem to get it to work with expressions with white space between words or numbers. Anyone have an easy fix? Thanks
