CakePHP管理面板订单

Question

我想按'Sr.排序表格。否“以降序排列。我不知道如何，因为它不是从数据库，但PHP生成。

<table> 
    <tr> 
     <th>Sr. No</th> 
     <th>Naslov</th> 
    </tr> 
    <?php $counter = 0; foreach($posts as $post) : $counter++; ?> 
    <tr> 
     <td><?php echo $counter?></td> 
     <td><?php echo $this->Html->link($post['Post']['title'], array('controller' => 'Posts', 'action'=> 'view', $post['Post']['id']), array('class' => 'link')); ?></td> 
    </tr> 
    <?php endforeach; ?> 
    <?php unset($post); ?> 
</table> 

Answer 1

你需要让$counter像下面递减顺序： -

<?php $counter = count($posts); foreach($posts as $post) : $counter--; ?> 
    <tr> 
     <td><?php echo $counter?></td> 
     <td><?php echo $this->Html->link($post['Post']['title'], array('controller' => 'Posts', 'action'=> 'view', $post['Post']['id']), array('class' => 'link')); ?></td> 
    </tr> 
<?php endforeach; ?> 

如果你想Naslov（指文章）也是在查询递减的顺序，那么你需要做的ORDER BY <column name like id> DESC

检查如何申请DESC： - https://stackoverflow.com/a/9837302/4248328

举例： - $this->Post->find('all', array('order' =>array('Post.id DESC')));
