I have stored many employee objects in session. how to populate the select box with the name of the all employees.i am very new to cakephp so explain me the syntax.
Assuming that your employee objects in your session are in the following format
array('Employee.id' => 'Employee.name')
you can populate the selectbox with the following statement in your views: $this->Form->select('employees', $employees)
(where $employees is an array formatted as above).
See also http://book.cakephp.org/view/1430/select for more info on the syntax of the select box.
