Answer 1

使用find('all')。当您只需要检索2个字段时，find('list')更合适

function Fetch() { 
    return $this->find('all', array(
        'fields' => array('Employee.id', 'Employee.firstname','Employee.lastname','Employee.salary') )
    ); 
}

然后使用$e代替$e['Employee']['id']代替$e{'Employee'}{'id'}。

如果您仍然收到错误，请在视图中debug($e)查看其格式是否正确
