 Rename "Consecutive" to "Circuit" 
The "Consecutive" rule is now renamed to "Circuit" to better reflect its
behavior of stopping at the first failure. I also favour this name
because it's much shorter.

When

  • When(Rule $if, Rule $then)
  • When(Rule $if, Rule $then, Rule $else)

A ternary validator that accepts three parameters.

When the $if validates, returns validation for $then. When the $if doesn't validate, returns validation for $else, if defined.

v::when(v::intVal(), v::positive(), v::notEmpty())->isValid(1); // true
v::when(v::intVal(), v::positive(), v::notEmpty())->isValid('not empty'); // true

v::when(v::intVal(), v::positive(), v::notEmpty())->isValid(-1); // false
v::when(v::intVal(), v::positive(), v::notEmpty())->isValid(''); // false

In the sample above, if $input is an integer, then it must be positive. If $input is not an integer, then it must not be empty. When $else is not defined use AlwaysInvalid
