Hello, I use CGridview and ajax search-functionality in my webapp. When I have searched for something and reload the page or click on a link and then move back one step all the search-criterias is reset. Is it possible to "save" the criterias so the search-results is still there?

I guess it should work if I remove ajax and use urls instead but I was wondering if it possible to do this while keeping ajax?

Hi adde,

You can store the search parameters in user session using CWebUser::setState() and read them using CWebUser::getState() afterward.

public function actionAdmin()
{
	$model = new Bill('search');
	$model->unsetAttributes();  // clear any default values
	if (isset($_GET['Bill']))
	{
		$model->attributes = $_GET['Bill'];
		Yii::app()->user->setState('BillSearchParams', $_GET['Bill']);
	}
	else
	{
		$searchParams = Yii::app()->user->getState('BillSearchParams');
		if ( isset($searchParams) )
		{
			$model->attributes = $searchParams;
		}
	}
	$this->render('admin',array(
		'model'=>$model,
	));
}

Thanks!

Is it possible to also save the pagination state? If I go to page 4 and then reload the page I get back to page one.

btw, where do I change the session expiration-time?

The pagination information comes in as a query string named 'SomeModel_page' where 'SomeModel' refers to your actual model name. And it is handled directly by the grid view widget.
So, maybe this ...

public function actionAdmin()
{
        $model = new Bill('search');
        $model->unsetAttributes();  // clear any default values
        if (isset($_GET['Bill']))
        {
                $model->attributes = $_GET['Bill'];
                Yii::app()->user->setState('BillSearchParams', $_GET['Bill']);
                // reset the page information
                Yii::app()->user->setState('BillPage', null);
        }
        else
        {
                $searchParams = Yii::app()->user->getState('BillSearchParams');
                if ( isset($searchParams) )
                {
                        $model->attributes = $searchParams;
                }
        }
        if (isset($_GET['Bill_page']))
        {
                Yii::app()->user->setState('BillPage', $_GET['Bill_page']);
        }
        else
        {
                $page = Yii::app()->user->getState('BillPage');
                if ( isset($page) )
                {
                        $_GET['Bill_page'] = $page;
                }
        }
        $this->render('admin',array(
                'model'=>$model,
        ));
}

Note that you have to reset the page information every time the search parameters get changed.

Works! Thank you, you're the best

Ah, fine.
And as to the session timeout, you can configure it in your application configuration.

	// application components
	'components'=>array(
		...
		'session'=>array(
			...
			'timeout' => 1440,
			...
		),
		...

Um, I think there's no need to make your own trick for it.
You just have to use CDbHttpSession for "session" application component to store/restore every user session state to/from database.

thats too grt..

i used Yii::app()->request->getUrl() to save current url, using GET. in one of my app.

Hi
this was the good approach
but I noticed a conflict when trying the click back to page 1 in a Cgrid
once we went forward in pagination , The GET['Model_page'] not being empty anymore it's the user->State
since The createUrl doesn't generate any GET param for the first page link it loops on the last state.

if Model_page is set on page one as well it would do the trick
any ideas on how this could be forced ?
Thanks
Tibor

I found that if you once in session will go to some page and/or put filter params, it will be saved even if you will reeneter the page from other admin pages. I think it should be fixed.
The way is easy - reset session params, when you enter outside controller.

public function actionAdmin()
{
	if (!isset($_SERVER['HTTP_REFERER'])or(!strpos($_SERVER['HTTP_REFERER'], '_ControllerName_'))) //change _ControllerName_ to your controller page
	{
		Yii::app()->user->setState('BillSearchParams', null);
		Yii::app()->user->setState('BillPage', null);
	}
        $model = new Bill('search');
	...
