How can I remove all whitespace entered by a user from an input box (ie card number)
numero = 48[grep search=[^0-9]&replace=][card][/grep]In this case, [^0-9], including the square brackets, is a grep expression. A grep bracket expression is a list of characters enclosed by [ and ]. It matches any single character in that list; if the first character of the list is the caret ^ then it matches any character not in the list. So in this case, grep will strip out anything that is not a digit.
[grep search=[^0-9]&replace=][card][/grep]
