Deleting Posts

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

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:
Plain Text View

Blog posts

link('Add Post', array('action' => 'add')); ?>

Id	Title	Actions	Created
	link($post['Post']['title'], array('action' => 'view', 'id' => $post['Post']['id']));?>	link('Delete', array('action' => 'delete', 'id' => $post['Post']['id']), null, 'Are you sure?' )?>

	16. link($post['Post']['title'], array('action' => 'view', 'id' => $post['Post']['id']));?> 17.	19. link('Delete', array('action' => 'delete', 'id' => $post['Post']['id']), null, 'Are you sure?' )?> 20.

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