Question

I have a simple form with a couple select inputs. One of which is a gender selections.

The input is generated like so:

echo $this->Form->input('gender_id', array(
    'options' => array(
        1 => 'Male',
        2 => 'Female'
    )
));

How can I ensure that only the given selects can be submit, so that a 3 or something can not be submitted?

I am using the Security component and it seems to protect against field name tampering but not value tampering.

Doing a simple comparison would not be practical for larger select lists like a State select. Also I’m trying to avoid doing extra queries to validate ids.

Require values to be in a specified list for your Model’s validation:

public $validate = array(
    'gender_id' => array(
      'allowed' => array(
      'rule'    => array('inList', array(1, 2)),
      'message' => 'Please select male or female.'
     )
   )
 );
