But since the first page link at the CLinkPager don’t show ‘page=1’ parameter, everytime I click the link from other page (say page 2), the application will think that I need the current ‘search’ (whose current page value is 2).
To rephrase the question, is there any way to make CLinkPager shows param ‘page=1’ at the first page link? Or do you have another suggestion on handling this
As I know CLinkPager store all $_GET params in url automatically. So if you use a form(wich method is get) in your page as “search model”(which return CDataProvider) you don’t need to think about it. It’s already in yii.
public function actionIndex() {
$model = new User();
if (isset($_POST['User'])) {
$model->setAttributes($_POST['User']);
} else {
if (isset($_GET['search'])) {
$searchId = $_GET['search'];
//Just getting a variable stored in the session
//array(
// $searchId => array(
// 'model' => $model //the search model
// 'pageSize' => $pageSize //current pagination page size
// 'currentPage' => $currentPage //the search model
// )
//);
$search = Yii::app()->user->getSearch($searchId);
$model->setAttributes($search['model'], false);
$currentPage = $search['currentPage'];
$pageSize = $search['pageSize'];
} else {
//create default search
}
}
//Managing pageSize parameter
if (isset($_GET['pageSize'])) { //Check whether there is pageSize in $_GET parameters
if (in_array($_GET['pageSize'], $this->getPageSizes())) {
$pageSize = $_GET['pageSize'];
} else {
$pageSize = self::DEFAULT_SEARCH_PAGESIZE;
}
} else if (!isset($pageSize)) { //Check whether pageSize is already defined before
$pageSize = self::DEFAULT_SEARCH_PAGESIZE;
}
//Managing currentPage parameter
if (isset($_GET['page'])) { //Check whether there is page parameter in $_GET parameter
$currentPage = $_GET['page'];
} else if (!isset($currentPage)) { //Check whether page is already defined before
$currentPage = self::DEFAULT_CURRENT_PAGE;
}
//Saving all into new session
$newSearch = array(
'model' => $model->getAttributes(),
'currentPage' => $currentPage,
'pageSize' => $pageSize,
);
//Check whether if there is a search before and if it exists check whether the two search is the same
if (!isset($search) || (serialize($search) != serialize($newSearch))) {
//Saves into session
$searchId = Yii::app()->user->saveSearch($newSearch);
} //else use the old search id
//-----------------------------------------------------
//Building the search
//Setting criteria
$criteria = new CDbCriteria(array(
'select' => array(
'*', //just to simplify things
),
));
//Appending criteria to search model used
$criteria = $model->search($criteria);
//Appending pagination to current variables
$pagination = array(
'pageSize' => $pageSize,
'pageVar' => 'page',
'currentPage' => $currentPage - 1,
'params' => array(
'search' => $searchId, //include the search ID in the link pager request URL
)
);
//Creating dataProvider for the search
$dataProvider = new CActiveDataProvider('Property', array(
'criteria' => $criteria,
'pagination' => $pagination,
));
//Rendering
$this->render('index', array(
'dataProvider' => $dataProvider,
'pageSize' => $pageSize,
'model' => $model,
'searchId' => $searchId,
));
}
the problem is, every first page link in the CLinkPager wont include a ‘param=1’ query string in the request, so it always assume the page stored in the session. If you want to give a better suggestion, please do.
