Yes, that's exactly what I wanted, I needed to "pre-set" the content
of the field and to avoid showing a select with all the registered
users when adding a new post(views\posts\add.ctp), I opted for
creating a private function , _usersUserid() , in the
app_controller.php , that returns the user_id of the current logged-
in user
*************app_controller.php****************
function _usersUserid(){
$users_userid=0;
if ($this->Auth->user()){
$users_userid=$this->Auth->user('id');
}
return $users_userid;
}
which I then send to the "add" view
function beforeFilter() {
//some other code
$this->set('users_userid',$this->_usersUserid());
}
*************Add View (views\posts\add.ctp) ****************
Where in order to know which user registers the new post , I've
created a new input hidden field to store the user_id
<?php
//echo $this->Form->input('user_id');
echo $this->Form->input('user_id',array('type' => 'hidden',
'value' => $users_userid ));
echo $this->Form->input('title');
echo $this->Form->input('body');
?>
and with this everything works fine, but I'm not so sure if this is
the best solution. what do you think??
thanks in advance
P.S. Sorry for my English
