Re: integer validation

$foo = $query->param('should_be_int');
warn "Not an integer!" if ($foo =~ /[^0-9\-]/)
[download]

Replace the warn with whatever error handling suits your taste.
EDIT:Sigh. Totally forgot negative integers. =( Fixed.

That allows the following input: `-54 54- 5-4` [download] I try to specify exactly what is valid: `/^-?\d+$/` [download] Update: Yup, Kanji is right (note the lowercase z). I never had that problem because I chomp my input first. --isotope http://www.skylab.org/~isotope/	[reply] [d/l] [select]

I try to specify exactly what is valid: Then wouldn't you want `/\A-?\d+\z/`? If it's there, `$` will match a single newline at the end of your string, and you'd end up matching something bogus like "7\n". --k.	[reply]

Jeez. Of course you're right. Something about quarter past 4 on a warm friday afternoon seems to have made thinking difficult. Trinary	[reply]
