How to fix approval system in CakePHP - php

Question

I made a blog and I can leave comments to my articles, then I made an Approve button, need to make the approve function.
I need to make it to work. I just can't, no matter what I try. I want to be able to approve or not a comment before it's posted. I have tried everything I could think of.
<?php
namespace App\Controller;
class CommentsController extends AppController
{
public function index()
{
$comments = $this->Comments->find('all');
$this->set(compact('comments'));
}
public function view($id = null)
{
$comment = $this->Comments->get($id);
$this->set(compact('comment'));
}
public function add()
{
$comment = $this->Comments->newEntity();
if ($this->request->is('post')) {
$comment = $this->Comments->patchEntity($comment, $this->request->data);
$comment->user_id = $this->Auth->user('id');
$comment->aproved = 0;
$comment->article_id = $this->request->data['article_id'];
if ($this->Comments->save($comment)) {
$this->Flash->success(__('Your comment has been saved.'));
return $this->redirect(['controller' => 'Articles', 'action' => 'view', $comment->article_id]);
}
$this->Flash->error(__('Unable to add your comment.'));
}
$this->set('comment', $comment);
}
public function aprove()
{
}
}

Answer 1

Try this
Your link should look like this:
$this->Html->link('approve', array('controller' => 'your-controller', 'action' => 'aprove', $comment_id, $value['Comment']['aproved']));
and your controller function is:
public function aprove($comment_id, $approve_value)
{
if(isset($comment_id) && !empty($comment_id)){
$approve = $this->Comments->find('first',array('conditions'=>array('id'=>$comment_id),'fields'=>array('Comment.id, Comment.approve')));
if(!empty($approve)){
$this->Comments->id = $approve['Comment']['id'];
$this->Comments->saveField('aproved', $approve_value);
}
}
}
