 echo "invalid"

I get the error,

Code:
grep: RE error 16: Bad number.

Any help will be appreciated.

Hi Vino,

Can you give the date validation script as per the following requirement:

I want a sample Date validation script using if loops.
The script should first compare "year".If the year is lesser than the current year,It should go for "month" checking.
I have the script that splits the date into year,month and date.I want only the checking part.
My if loop checking is not work properly.
Can you show the right way of checking?

Regards
Dave

cgi::untaint::date

CGI::Untaint::date(3pm) 				User Contributed Perl Documentation				   CGI::Untaint::date(3pm)

NAME

       CGI::Untaint::date - validate a date

SYNOPSIS

	 use CGI::Untaint;
	 my $handler = CGI::Untaint->new($q->Vars);

	 my $date = $handler->extract(-as_date => 'date');

DESCRIPTION

       is_valid

       This Input Handler verifies that it is dealing with a reasonable date. Reasonably means anything that Date::Manip thinks is sensible, so
       you could use any of (for example):
	 "December 12, 2001"
	 "12th December, 2001"
	 "2001-12-12"
	 "next Tuesday"
	 "third Wednesday in March"

       See Date::Manip for much more information on what date formats are acceptable.

       The resulting date will be a Date::Simple object.  Date::Simple for more information on this.

       date_format

       By default ambiguous dates of the format 08/09/2001 will be treated as UK style (i.e. 8th September rather than 9th August)

       If you want to change this, subclass it and override date_format()

WARNING

       Date::Manip does not play nicely with taint mode. In order to work around this we locally clobber Date::Manip's 'timezone' code. As we're
       only interested in dates rather than times, this shouldn't be much of an issue. If it is, then please let me know!
