    <?php endif; ?>

this database table

CREATE TABLE IF NOT EXISTS `articles` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `title` varchar(255) NOT NULL,
  `content` text NOT NULL,
  `created` datetime NOT NULL,

  `views` int(11) NOT NULL,

  `status` tinyint(4) NOT NULL DEFAULT '0',

回答1:

Try changing your first find from this:

$article = $this->Article->Comment->find(

To this:

$article = $this->Article->find(...

(Notice the lack of "Comment" in the second one)

Also - there's really no reason you should need to write 2 separate queries - that's something CakePHP can handle easily for you with the Containable Behavior

---

NEXT FIX (after changes were made from prev part of answer):

Do a print_r on your $article variable. I assume you'll see that it should be:

$article[0]['Article']

instead of

$article['Article']

回答2:

Hey instead of the following:

<?php echo $article['Article']['title']; ?>

try

<?php echo $article['title']; ?>

I am not sure yet why that happens, but it has worked for me in other occasions...

Also on the foreach statement for comments I noticed you have

<?php foreach($comment as $comments){ ?>

Which I dont think will display your comments correctly. You should have

<?php foreach($comments as $comment){ ?>

And in your controller for this, use

 $comments = $this->Article->Comment->find('all', ...

I am creating a similar application and at least that is how I handled everything.

If you need to, I will post back or email you my articles controller, comments controller and corresponding views for your review.

Thanks,
