yii2 Unable to verify your data submission - session

Question

I use nginx, PHP 5.5.14, php-fpm, yii2, mac os.
I changed yii config to store session in database (postgress, user is superuser).
This is in my config:
'session' => [
'class' => 'yii\web\DbSession',
'sessionTable' => 'session',
],
And now when I try to register new user I've got this error:
Bad Request (#400)
Unable to verify your data submission
Here is a part of log:
10 17:25:57.434 info yii\db\Command::query SELECT "data" FROM "session" WHERE "expire">1425993957 AND "id"='cfg9sutufqchr1tdose4cack15'

BTW,
I've got <?= Html::csrfMetaTags() ?> in head section and I have csrf input in my form. So it seems not the problem
I don't want to do public $enableCsrfValidation = false; because I think it's not solution but workaround.
How could I understand what cause this error?
As I mentioned earlier problem only appears when I store session in database.
Some additional information:
I could set and get variable from session. For example, I put it in beoreAction of Controller.php
Yii::$app->session->set('test', 'qwe');
$t = Yii::$app->session->get('test') ;
var_dump($t);
But after that If I comment first line like this
//Yii::$app->session->set('test', 'qwe');
$t = Yii::$app->session->get('test') ;
var_dump($t);
and refresh the page - I recieve NULL (BTW I could see Cookie:PHPSESSID=cfg9sutufqchr1tdose4cack15 in cookies after refresh).
So it seems there are some problems with session (DbSession) or maybe my php/php-fpm/nginx settings.

Answer 1

Looks like your session id changes. Check if the value of the session cookie changes after a second request. This happens when you misconfigure the domain that is set for the session cookie, make sure it matches the hostname in your URL.

Answer 2

I think this happens atimes when the server is messed up, all I needed to do was to restart my apache server.
For apache on MacOSx
sudo apachectl restart
For apache on Linux
sudo service apache2 restart
or
sudo service httpd restart

Answer 3

i hv used this while calling logout
$menuItems[] = [
'label' => 'Logout (' . Yii::$app->user->identity->username . ')',
'url' => ['/site/logout'],
// 'linkOptions' => ['data-method' => 'get']
'data-method' => 'get'
];
in main .php change post to get
---------------------------------------------------
and have changes this also
$url = Html::a('Logout',
['/site/logout'],
['class' => 'btn btn-success', 'data-method' => 'get']);
this is also in main.php
--------------------------------------------------------------------
in behaviour of site controller also
public function behaviors()
{
return [
'access' => [
'class' => AccessControl::className(),
'only' => ['logout', 'signup','index'],
'rules' => [
[
'actions' => ['signup'],
'allow' => true,
'roles' => ['?'],
],
[
'actions' => ['logout','index'],
'allow' => true,
'roles' => ['#'],
],
],
],
'verbs' => [
'class' => VerbFilter::className(),
'actions' => [
'logout' => ['get'],
],
],
];
}
change post to get...and it will work....

Answer 4

What I did is, I just make the "csrfParam" different for both backend and frontend and after "php init" command everything is now working fine.
Not sure whether its a bug or we must have to set different "csrfParam" in case if we use DBsession.

Answer 5

Not sure if it's late, but I found this solution which worked for me in a similar case of Yii2 framework spitting 400 Bad Request at POST form requests.
Simply add this code in your form to manually include a CSRF input field for the key and Yii2 will accept the data submission:
<?php
use Yii;
echo Html::tag('input', '', ['type' => 'hidden', 'name' => '_csrf-backend', 'value' => Yii::$app->request->getCsrfToken()]);
?>
Note: this is for the advanced template. In the long run I suggest not to use a framework that bases on short tags as PHPers would know its a curse.
