When I try to add a post: http://i.stack.imgur.com/fhRVn.png

My PostsController.php is:
App::uses('AppController', 'Controller');
class PostsController extends AppController{
public $components = array('Session');
public $helpers = array('Html', 'Form');
public function index() {
$this -> set('posts', $this->Post->find('all'));
}
public function view($id = null){
if(!$id){
throw new NotFoundException(_('il faut choisir un post'));
}
$post=$this->Post->findById($id);
if(!$post){
throw new NotFoundException(_('invalide Post !'));
}
$this->set('post',$post);
} // fin de "view"
public function add(){
if($this->request->is('post'))
{
$this->Post->create();
if ($this->Post->save($this->request->data)) {
$this->Session->setFlash(__('Your post has been saved.'));
return $this->redirect(array('action' => 'index'));
}
$this->Session->setFlash(__('Unable to add your post.'));
}
//debug($this->Post->validate);
}//fin d'ajout
} // fin de "appcontroller"
My Post.php model file is:
class Post extends appModel {
//public $name='Post';
public $validate = array(
'title' => array('rule' => 'notEmpty'),
'body' => array('rule' => 'notEmpty')
);
}
My view form post is:
echo $this->Form->create('post');
echo $this->Form->input('title');
echo $this->Form->input('body',array('rows' => '3'));
echo $this->Form->end('Ajouter');

Answer 1

in your view maybe your problem that you Model is Post not post
echo $this->Form->create('Post');
echo $this->Form->input('title');
echo $this->Form->input('body',array('rows' => '3'));
echo $this->Form->end('Ajouter');
