I was going crazy always setting the current $user_id, $owner_id in my
controller and then testing again for empty() in my views. So I put
all my commonly used context variables into Session and wrote a
controller function to keep it initialized and in sync with the
controllers and views. (This might also be a good place to put random
things like the current page # from paginate).
Now in my view, I can just do something like:
if($cur['authenticated']) {
$menubar[]="Welcome <b>{$othAuth->user('username')}</b>";
}
It makes my code a little more readable, but is it good practice, or
am I opening myself up to future problems or security risks?
file app_controller.php:
function getCurrent() {
// init $cur with defaults
$keys = array('owner_id', 'bundle_id', 'asset_id', 'user_id',
'user_group_level');
$this->cur = array_fill_keys($keys, NULL);
$this->cur['authenticated']=false;
if ($this->Session->valid()) {
// defaults to NULL if Session key not set
$this->cur['owner_id'] =
$this->Session->read('Current.owner_id');
$this->cur['bundle_id'] = $this->Session-
>read('Current.bundle_id');
$this->cur['asset_id'] =
$this->Session->read('Current.asset_id');
if ($this->Session->check('othAuth.' .
$this->othAuth->hashkey)) {
$this->cur['authenticated']=true;
$this->cur['user_id'] =
$this->othAuth->user('id');
$this->cur['user_group_level']=
$this->othAuth->group('level');
}
} else {
debug("************************ Error: session not
valid, deleting
Current.");
$this->Session->del('Current');
}
// set $cur in Views
$this->set('cur', $this->cur);
}
function setCurrent($key, $value) {
$this->Session->write("Current.$key",$value);
$this->cur[$key]=$value;
$this->set('cur', $this->cur); // why do I have to set again if
}
