Where is CakePHP client side form validation?

Question

CakePHP automatically does some client side form validation for me - checking whether a field is empty or if an email field is actually an email address. Incorrect fields get a nice little dropdown with an error message.

Where is this managed? I want to add this sort of validation to my confirm_email field.

Answer 1

$this->Form->input('textfield',array('required'=>true));

will do some HTMLrequired field
