Next, let's make a way for users to delete posts. Start with a delete() action in the PostsController:

function delete($id) {
	$this->Post->delete($id);
	$this->Session->setFlash('The post with id: '.$id.' has been deleted.');
	$this->redirect(array('action'=>'index'));
}

1. function delete($id) {
2. $this->Post->delete($id);
3. $this->Session->setFlash('The post with id: '.$id.' has been deleted.');
4. $this->redirect(array('action'=>'index'));
5. }

This logic deletes the post specified by $id, and uses $this->Session->setFlash() to show the user a confirmation message after redirecting them on to /posts.

Because we're just executing some logic and redirecting, this action has no view. You might want to update your index view with links that allow users to delete posts, however:

/app/views/posts/index.ctp

<h1>Blog posts</h1>
<p><?php echo $html->link('Add Post', array('action' => 'add')); ?></p>
<table>
	<tr>
		<th>Id</th>
		<th>Title</th>
                <th>Actions</th>
		<th>Created</th>
	</tr>

<!-- Here's where we loop through our $posts array, printing out post info -->

	<?php foreach ($posts as $post): ?>
	<tr>
		<td><?php echo $post['Post']['id']; ?></td>
		<td>
		<?php echo $html->link($post['Post']['title'], array('action' => 'view', 'id' => $post['Post']['id']));?>
		</td>
		<td>
		<?php echo $html->link('Delete', array('action' => 'delete', 'id' => $post['Post']['id']), null, 'Are you sure?' )?>
		</td>
		<td><?php echo $post['Post']['created']; ?></td>
	</tr>
	<?php endforeach; ?>

</table>

1. /app/views/posts/index.ctp
2. <h1>Blog posts</h1>
3. <p><?php echo $html->link('Add Post', array('action' => 'add')); ?></p>
4. <table>
5. <tr>
6. <th>Id</th>
7. <th>Title</th>
8. <th>Actions</th>
9. <th>Created</th>
10. </tr>
11. <!-- Here's where we loop through our $posts array, printing out post info -->
12. <?php foreach ($posts as $post): ?>
13. <tr>
14. <td><?php echo $post['Post']['id']; ?></td>
15. <td>
16. <?php echo $html->link($post['Post']['title'], array('action' => 'view', 'id' => $post['Post']['id']));?>
17. </td>
18. <td>
19. <?php echo $html->link('Delete', array('action' => 'delete', 'id' => $post['Post']['id']), null, 'Are you sure?' )?>
20. </td>
21. <td><?php echo $post['Post']['created']; ?></td>
22. </tr>
23. <?php endforeach; ?>
24.  
25. </table>

This view code also uses the HtmlHelper to prompt the user with a JavaScript confirmation dialog before they attempt to delete a post.
