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>
?>
然后出现这个问题
该怎样解决呢？
