LessThan class

A validation rule for checking if a value is less than a specified number.

The LessThan class is a concrete implementation of the FormifyRule abstract class. It is used to validate whether a value is less than a specified numeric value.

This rule checks if the input value is less than the provided number. If the value is greater than or equal to the number, an error message is generated.
