从cakephp中的数据库获取值时出错

-1

我从cakephp应用程序中的表sessionapps中获取值。从cakephp中的数据库获取值时出错

我index.ctp文件如下

<table> 
<tr><td>ID</td><td>Title</td><td>Post</td><td>Actions</td><td>Created On</td></tr> 
<?php foreach ($sessionapps as $post): ?> 
<tr><td><?php echo $post[Sessionapp][id];?></td> 
    <td><?php echo $data->Html->link($post[Sessionapp][title],array('controller'=>'sessionapp','action'=>'view',$post[Sessionapp][id]));?></td> 
    <td><?php echo $post[Sessionapp][post];?></td> 
    <td><?php echo $this->Html->link('Edit Post ', array('action' => 'editarticle', $post[Sessionapp][id]));?></td> 
    <td><?php echo $post[Sessionapp][created];?></td></tr> 
<?php endforeach; ?> 
</table>

，我已经创造了控制器sessionapps_controller.php，并在其中加入行动指标如下

function index() 
    { 
       $this->set('sessionapps', $this->Sessionapp->find('all')); 
    }

但它无法正常工作，并给予错误

Notice (8): Use of undefined constant Sessionapp - assumed 'Sessionapp' [APP/views/sessionapps/index.ctp, line 14] 

Notice (8): Use of undefined constant id - assumed 'id' [APP/views/sessionapps/index.ctp, line 14]

我的数组$ sessionapps如下

Array ([0] => Array ([Sessionapp] => Array ([id] => 1 [title] => The title [body] => This is the post body. [postby] => [created] => 2013-01-15 11:35:13 [modified] =>)) [1] => Array ([Sessionapp] => Array ([id] => 2 [title] => A title once again [body] => And the post body follows. [postby] => [created] => 2013-01-15 11:35:13 [modified] =>)) [2] => Array ([Sessionapp] => Array ([id] => 3 [title] => Title strikes back [body] => This is really exciting! Not. [postby] => [created] => 2013-01-15 11:35:13 [modified] =>))) 1

也发布你的错误。 – cartina

看到编辑的问题.. –

你有没有尝试我在你的视图文件下面张贴的答案。您没有正确引用数组元素。只需将foreach循环替换为我发布的那个。 – cartina

我认为它应该是这样的。

<?php foreach ($sessionapps as $post): ?> 
<tr><td><?php echo $post['Sessionapp']['id'];?></td> 
    <td><?php echo $data->Html->link($post['Sessionapp']['title'],array('controller'=>'sessionapp','action'=>'view',$post['Sessionapp']['id']));?></td> 
    <td><?php echo $post['Sessionapp']['post'];?></td> 
    <td><?php echo $this->Html->link('Edit Post ', array('action' => 'editarticle', $post['Sessionapp']['id']));?></td> 
    <td><?php echo $post['Sessionapp']['created'];?></td></tr> 
<?php endforeach; ?>

不工作...我已经用它了.. –

@Usman ok。然后尝试print_r（$ sessionapps）;它给了什么结果？ – cartina

@Usman查询$ this-> Sessionapp-> find（'all'）没有给出结果。所以$ sessionapps不包含你想在视图文件中显示的元素 – cartina
