Question

I am building a simple mechanism where a user can like a post by clicking on a link. I’m using GET rather than POST as I want to allow the method to fire via the URL.

That been said how do I save data using GET? As the request data doesn’t exist in this scenario… My model looks like:

class Like extends AppModel
{
    public $name = 'Like';

    public $belongsTo = array('User','Post');

}

and the method for adding looks like:

public function add( $id )
{
    $post = $this->Post->find('first', array( 
                'conditions' => array('Post.id'=>Tiny::reverseTiny($id)) 
            ));

    if (!$post)
    {
        throw new NotFoundException('404');
    }

    if($post['Post']['user_id'] == $this->Auth->user('id'))
    {
        $this->Session->setFlash('You can\'t like your own post... That\'s just silly!');
    }

    if ($this->Like->create())
    {
            $liked = $this->Like->find('first', array( 
                'conditions' => array('Like.id'=>Tiny::reverseTiny($id), 'Like.user_id'=>$this->Auth->user('id') ) 
            ));

            if(!$liked){
                $this->Like->saveField('user_id', $this->Auth->user('id'));
                $this->Like->saveField('post_id', $post['Post']['id']);

                $this->redirect(array('controller'=>'posts','action'=>'view','id'=>Tiny::toTiny($post['Post']['id']),'slug'=>$post['Post']['slug']));
            } else {
                $this->Session->setFlash('You already like this post!');
            }
    else
    {
        $this->Session->setFlash('Server broke!');
    }   
}

Can anyone help?

<?php echo $this->Html->link('1', array('controller'=>'followers','action'=>'add','id'=>Tiny::toTiny($post['Post']['id'])),
array('title'=>'Follow','class'=>'follow')); ?>

This part all works fine. It’s saving a new row in the DB on GET that I’m struggling with.

Hi you just need to make a link to your controller action and pass you variable in the url.

to be clear the link on the post to like is in your post view :
$this->Html->link(‘like this post’, array(‘controller’ => ‘like’, ‘action’ => ‘add’, $postId))

It should render a link like this :
http://www.yourWebSite/likes/add/1 to like the postId 1,

variables after your action (add) are interpreted as variable for your controller action

if your fonction add had been

public function add($postId, $wathever){

}

the url should look like http://www.yourWebSite/likes/add/1/blabla
where 1 is the first var for the add action and blabla the second one and so on.

this is the equivalent of a non rewriting url : ?postId=1&whatever=blabla

EDIT :

if(!$liked){
                //simulate the post behaviour
                $this->request->data['Like']['user_id'] = $this->Auth->user('id');
                $this->request->data['Like']['post_id'] = $post['Post']['id'];

                //save the data
                if ($this->Like->save($this->request->data)) {
                    $this->Session->setFlash(__('Thanks for your support !'));
                    $this->redirect(array('controller'=>'posts','action'=>'view','id'=>Tiny::toTiny($post['Post']['id']),'slug'=>$post['Post']['slug']));
                } else {
                    $this->Session->setFlash('Server broke!');
                }

}
