php - filter_input - set to default value if GET key not set
The filter_input function accepts an options parameter. Each filter accepts different options.

FITER_VALIDATE_INT should be FILTER_VALIDATE_INT. You are missing L in FILTER in all instances of the constant. Turning on error reporting would have thrown several Notice: Use of undefined constant FITER_VALIDATE_INT - assumed 'FITER_VALIDATE_INT' errors.
PHP filter_validate_int for numbers with preceding zero

Maybe something like: $mins = filter_input(INPUT_POST, 'hour', FILTER_VALIDATE_REGEXP, ['options' => [ 'regexp' => '/\d{1,2}/'] ]); Just adding the regex \d{1,2} as an example here, clearly you might want to define something better here. Alternatively you could use...
