cakephp问题
这个是我写的代码:
<?php <br />
class BooksController extends AppController<br />
{<br />
var $name='Books';<br />
var $help='form';<br />
function index() { <br />
$this->Book->recursive = 1; <br />
$books = $this->Book->find('all',array('field'=>array('Book.isbn','Book.title','Author.name'))); <br />
$this->set('books', $books); <br />
} <br />
function add()<br />
{<br />
if(!empty($this->data))<br />
{<br />
$this->Book->create();<br />
$this->Book->save($this->data);<br />
$this->redirect(array('action'=>'index'));<br />
}<br />
$authors = $this->Book->Author->generateList();<br />
$this->set('$authors',$authors);<br />
}<br />
} <br />
?>
