I'm using codeigniter with PHP. I'm using following form,

<?php
    echo form_open('/register/create_new', $form_params);
?>

DOB: <input type="text" id="dob" name="reg[dob]">
     <input type="submit" value="Create Account" />
</form>

here, #dob is in dd-mm-yyyy format.

my validation code is,

array(
  'field' => 'reg[dob]',
  'label' => 'DOB',
  'rules' => 'required'
)

How can i set the rules for correct date validation?
