The default JUser::setParam() method sets parameters only to the session. Is is possible somehow to store parameters not in the session, that they would be always available? I also found in users table field params, which stores some parameters for current user, but don't know how to add data there...
Have you tried to save the object after adding your param?
$user = JFactory::getUser();
$user->setParam($key, $value);
$user->save;
An easy and comfortable approach would be to use the popular Community Builder Extension which lets you define custom user fields in the administrator backend. It has an API to obtain the CB User Object and to write and read those fields which get stored in the DB as opposed to the session. Simple example without knowing your Joomla/CB version (works with Joomla 2.5 and CB 1.8) and the place (site, admin, external) where this should be executed (assuming your parameter is named customParam and the user id is 42):
cbimport( 'cb.field' );
$mosCbUser = CBUser::getUserDataInstance(42);
// read value
$customParameter = $mosCbUser->customParam;
// write value
$mosCbUser->customParam = 'newnew';
$mosCbUser->store();
/* write value to DB directly with optional boolean third parameter
specifing whether to trigger the user update plugins
like onBeforeUserUpdate or onAfterUserUpdate
*/
$mosCbUser->storeDatabaseValue('cb_adresse', 'new address', false);
be sure to be in CB plugin context, if not already the case, include e.g. like
global $_CB_framework, $_CB_database, $ueConfig;
$app = JFactory::getApplication();
include_once( $app->getCfg( 'absolute_path' ) . '/administrator/components/com_comprofiler/plugin.foundation.php' );

I am trying to access to a stored Session ID and use it as a reference.
In laravel, the session ID keeps changing in every request. I understand this has been done to avoid session hijacking.
One possible solution is to use Session::unguard(), but how to use this?
The above code does not help, because the session ID keeps on changing:
$ses = session()->getId();
$a =session()->getId();
$chat = chatParticipants::where("session_id", $a)->first();
Two solutions:
You can regenerate the ID manually as per the docs:
$request->session()->regenerate();
Storing a key with every session, and use it for reference.
To store a new key:
`session(['key' => 'value']);`
To retrieve the key:
$value = $request->session()->pull('key', 'default');
I'm coding an API and I'm doing the create method. I'm doing the following without needing a form:
$params = array('title' => 'test', 'parent_id' => 781);
// bind data
$place = new Place();
$place->bind($params);
// validate params
$errors = $this->validator->validate($place);
I need to check that parent_id is a correct value (its object exist - i know how to do this) and after that, I need to set some values dependent on the parent. So at the end the Place object will have the fields: title, parent_id, level, country_id for example.
How would you do this? On the validation? How? If not, how to avoid calling two times the DB to get the parent object?
You should first validate & then set any additional values afterward. Anything that modifies the value does not belong in the validator.
If your using doctrine, it should load the parent object into memory when you first access it, so it won't need to actually query the database again when you access the parent object a second time.
I'm currently trying to display all online users on my webpage using the php session variables. To do this, whenever a user logs in or out, a column in a database gets set to "online" or "offline".. However this doesn't entirely work since the database doesn't get updated when the user closes their browser (and therefor destroys the session).
So is there another way of checking if a certain sessionid is set??
Currently I am setting the session like this:
session_start();
$_SESSION['username']="Example Username";
To check from the current users page if there is a session variable set we can simply use:
if(isset($_SESSION['username']))
{
//username is set
}
But if we need to check if a specific user is online, how do we get for instance an array of all the session variables that have been set? e.g.
//Get all $_SESSION['username'] vars
//loop through array and check for specific $_SESSION
for($i=0; ... )
{
if( $_SESSION['username'][$i] == "User 1" )
{
//do something
}
}
From all that I've read so far, there doesn't seem to be a way to get an array of all sessions on your page..
So is there a better way of doing it, e.g. how do facebook, twitter, etc handle this stuff?
Thanks for your help!
One solution is to store a timestamp in your database in addition to the online/offline flag that records the last time a user accessed any of your website resources. Then you might just consider them offline after 15 minutes or some other constant value.
The other solution is to play with the callbacks here http://php.net/manual/en/function.session-set-save-handler.php where I think you can handle the gc callback and set the offline flag in your database.
If you search on that page for class SessionDB or go here it looks like somebody has implemented some version of this already in a custom class!
you can use a simple update query
for example you have a table users and in that you have a column called status(online/offline)
on your login.php use
<?php
//your user verification code
if(variable that holds your sql query){
$user_status=('UPDATE user SET status= online WHERE email="'your user email selector'")
}
then on the logout do a similar script just change the online value to offline
You could try this:
foreach ($_SESSION as $sessionKey => $sessionValue)
{
if( $sessionKey == 'username' ) && ( $sessionValue == 'User 1' )
{
//do something
}
}
I use Symfony 1.4.11. I have two tables "companies" and "ads". When user add new ad, he can connect ad with his company.Before it I check, if user have company, for example I have variable $has_company, if $has_company==1 - user has company, if $has_company==0 he has not company. If user want connect company with ad, he must check checkbox :-) So I want to validate checkbox, If user check checkbox, and he has not company,I want to show messages, that first he must create company.... Is it possible? Can I use sfValidatorBoolean ? If yes, how to validate variable has_company? Thank you!
I think you can create a method in myUser class to check if the current user has a company (if your models user and company are linked).
And then, you can pass the result of this method in option of your form.
For validation, you can use a callback validator : http://www.symfony-project.org/forms/1_4/en/B-Validators#chapter_b_sub_sfvalidatorcallback
you can use halt_on_error option like
$v = new sfValidatorAnd(
array(
new sfValidatorString(array('max_length' => 255)),
new sfValidatorEmail(),
),
array('halt_on_error' => true),
array('invalid' => 'The input value must be an email with less than 255 characters.')
);
can anyone give me an example on how to create Sessions and write data to it. I've seen syntax on how to write data to a session using write command. But how to create a session and retrieve the values in it.
In my application, I have two data, form_id and user_id that needs to be used in all the page requests. So how do I save it as a session variable and use it across the application?
EDIT
function register()
{
$userId=$this->User->registerUser($this->data);
$this->Session->write('User.UserId',$userId);
//echo "session".$this->Session->read('User.UserId');
$this->User->data=$this->data;
if (!$this->User->validates())
{
$this->Flash('Please enter valid inputs','/forms' );
return;
}
$this->Flash('User account created','/forms/homepage/'.$userId);
}
How to use the session variable 'User.UserId' instead of $userId in $this->Flash('User account created','/forms/homepage/'.$userId);
And can I use this variable in all my view files,because in all the page requests I also pass the userId?
EDIT 2
I have 2 controllers,user and form. I write the userid to a session variable in the users_controller. I have a view file called homepage.ctp,whose action is in the forms_controller. Now how can I use the session variable defined in the users_controller in the homepage? Sorry if I am asking silly questions. I went through the cakebook,but my doubts weren't cleared. I'm also trying trial and error method of coding,so please help me.
EDIT 3
I have a session variable 'uid' which is the user id in the home page action of a controller.
$this->Session->write('uid',$this->data['Form']['created_by']);
I need the same variable in the design action method of the same controller.
When I give
$uid=$this->Session->read('uid');
echo "uid: ".$uid;
the value is not echoed.
Can't I use the session variable in the same controller?
The bakery is your best friend:
http://book.cakephp.org/view/398/Methods
All your session read/writes belong in the controller:
$this->Session->write('Person.eyeColor', 'Green');
echo $this->Session->read('Person.eyeColor'); // Green
In cake php you can create session like this
$this->request->session()->write('user_id', 10);
and you can read session value like this
echo $this->request->session()->read('user_id');
Super Simple!
You don't have to write any code to create session, they are already built in. Then you just use the read and write sessions as mentioned above. Also see here for more details:
http://book.cakephp.org/2.0/en/core-libraries/components/sessions.html
Used in Controllers
http://book.cakephp.org/2.0/en/core-libraries/helpers/session.html
Used in Views
cakephp 4 example of session usage in controllers, views and cells
$session = $this->request->getSession();
$session->write('abc', 'apple');
echo $session->read('abc');
In this case it would be:
$this->Flash('User account created','/forms/homepage/'.$this->Session->read('User.UserId'));
and your second question is anwered by Jason Miy (http://api.cakephp.org/class/session-helper). You can simply use this in your view:
$userId = $session->read('User.UserId');
Reading the appropriate cookbook pages slowly and carefully usually helps a lot...
I found out the reason why the uid wasn't being echoed(edit 3 part of the question).
It is due to a silly mistake, had a white space after the end tag ?> in the controller. Now it is working fine.
when I have strange session behavior, and this help me.
MODEL:
function clearAllDBCache() {
$db =& ConnectionManager::getDataSource($this->useDbConfig);
$db->_queryCache = array();
}

Acess your Helper SessionHelper in lib/Cake/View/Helper/SessionHelper.php and add the method:
public function write($name = null) {
return CakeSession::write($name);
}
