CakePHP. Multiple Forms per page - php

Question

I have website with few short News , to every News we can write a comment via Form. And there my problem occur.
When i fill my fields in one form, after pressing button, all forms are reloading without saving, and every field in every form must be filled out so they're treated like a one part how to avoid it ?
Additional info ( Info is my main modal with news, it's joined with Com modal)
index.ctp Form
<br><h5>Add comment:</h5><br>
<?php echo $this->Form->create('Com'); ?>
<?php echo $this->Form->input(__('mail',true),array('class'=>'form-control')); ?>
<?php echo $this->Form->input(__('body',true),array('class'=>'form-control')); ?>
<?php $this->request->data['ip'] = $this->request->clientIp(); ?>
<?php $this->request->data['info_id'] = $info['Info']['id']; ?>
<?php echo $this->Form->submit(__('Add comment',true),array('class'=>'btn btn-info')); ?>
<?php $this->Form->end(); ?>
controller ComsController.php
public function add()
{
if($this->request->is('post'))
{
$this->Infos_com->create();
$this->request->data['Infos_com']['ip'] = $this->request->clientIp();
$this->request->data['Infos_com']['id_infos'] = $number;
if($this->Infos_com->save($this->request->data))
{
$this->Session->setFlash(__('Comment is waiting for moderating',true),array('class'=>'alert alert-info'));
return $this->redirect(array('controller'=>'Infos','action'=>'index'));
}
$this->Session->setFlash(__('Niepowodzenie dodania komentarza',true),array('class'=>'alert alert-info'));
return TRUE;
}}
and Model Com.php, i comment lines to avoid neccesity of filling every field in forms
class Com extends AppModel
{
public $belongsTo = array('Info');
/*public $validate = array(
'mail'=>array(
'requierd'=>array(
'rule'=>array('notEmpty'),
'message'=>'Write your email'
)
),
'body'=>array(
'required'=>array(
'rule'=>array('notEmpty'),
'messages'=>'Write smth'
)
)
); */
}

I don't think you can access $this->request->data in a view (the data should be entered with a form, it was not submitted). You should use hidden fields to pass arguments like IP od id... Example:
echo $this->Form->input('Infos_com.client_id', array(
'type' => 'hidden',
'value' => $value
));
If you have multiple forms, it would be useful to separate their fields. For example:
echo $this->Form->input('Infos_com.' . $news_id . '.body', array('label' => __('body')));
This way you will get an array like:
$this->request->data['Infos_com'][$news_id]['body'].
And then you can make your logic in the model.
