How to write this select box in cakephp ..

Make a list query in your controller (http://book.cakephp.org/2.0/en/models/retrieving-your-data.html):

$results = $this->Model->find('list', $options);

and then add it to the form element in your view (http://book.cakephp.org/2.0/en/core-libraries/helpers/form.html):

$this->Form->input('Model.field', array('options' => $results));
