Regex for number check below a value

Question

I\'m still a beginner at regex so this is a little above me currently.

I need to validate a number input to two characters and it can\'t be more than the value 12.

Answer 1

For something like this (testing if an integer is less than a given value), you should really not use a regex.

Instead, just use a simple condition like this one (the syntax will depend on the language you're working with) :

if ($variable <= 12) {
  // OK
}
else {
  // Not OK
}
