Hi.
I need a help in refactoring, or in design 
. I did my webapp, it works well/fine. But I still can’t understand well the Ajax process in the Yii.
For example, when I use the $.fn.yiiGridView.update() method, I saw this return by the all webpage and not just with the content of CGridView. It was interesting for me.
But now:
At the index view, I use a CGridView, but without pager!
This is a simple bet game webapp. And at the index.php I view only 10 bet/result on the page, and after 10 seconds I view the next 10 bet/result and again the next 10 result/bet after 10 seconds , with JavaScript.
The simple process like this:
[list=1]
[*] actionIndex() is called, it renders the index.php (the index.php contains the JS codes the design, but not the CGridView, where the webapp views the results)
[*] index.php rendert the _ajaxIndex.php files content.
[*] The JS code calculate the next 10 result, which will have to view on the webpage.
[*] actionAjaxIndex() is called. This give the refresh content of _ajaxIndex.php
[*] repeat from the 3. again. The JS code calculate again the next 10 resut…
[*]Notice: While the admins insert the results at the admin webpage, the webapp has to show the temporary results. This is why I need to refresh the summary and the round JS variables in the _ajaxIndex.php
[/list]
Controller:
/**
* Lists all models.
*/
public function actionIndex() {
Yii::app()->language='hu';
$model = new Result('search');
$model->unsetAttributes();
if (isset($_GET['Result']))
$model->attributes = $_GET['Result'];
if (isset($_POST['offset']) && $_POST['offset'] >= 0)
$model->offset = $_POST['offset'];
$summary = Result::getCountSavedResults();
$model->isLimited = true;
$this->layout='projector';
$this->render('index', array('model' => $model, 'summary'=>$summary));
//$this->actionAjaxIndex();
}
/**
* List all models by Ajax request.
*/
public function actionAjaxIndex() {
Yii::app()->language='hu';
$model = new Result('search');
$model->unsetAttributes(); // clear any default values
if (isset($_GET['Result']))
$model->attributes = $_GET['Result'];
if (isset($_POST['offset']) && $_POST['offset'] >= 0)
$model->offset = $_POST['offset'];
$summary = Result::getCountSavedResults();
$model->isLimited = true;
$this->renderPartial('_ajaxIndex', array('model' => $model, 'summary'=>$summary));
}
I would like to terminate this code repeat in the actionIndex(). But I don’t have any idea how I can do… I tried to call actionAjaxIndex etc. But before I can call the actionAjaxIndex I got PHP errors from Yii. (Summary variable is not exist, etc.)
View - Index.php
<!--<h1><?php echo Yii::t('strings','Results'); ?></h1>-->
<?php
echo CHtml::image(Yii::app()->request->baseUrl.'/images/toplista.jpg', "Fogadás");
?>
<script type="text/javascript">
// Initialize the variables for calculating
var summary = <?php echo $summary ?>; // get all stored results
var timeout = 10 * 1000; // in Milliseconds -> multiply with 1000 to use seconds
var current = 0;
var turn = 0;
var rounds = Math.floor(summary / 10);
</script>
<?php $this->renderPartial('_ajaxIndex', array('model'=>$model, 'summary'=>$summary)); ?>
<script type="text/javascript">
// Refresh the CGridView's content in _ajaxIndex.php
window.setInterval("refresh()", timeout);
// Get the offset to the search() to set the criteria
// Increase turn.
function counter(){
turn += 1;
if(turn > rounds){
turn = 0;
}
return turn *10;
}
function refresh() {
<?php
echo CHtml::ajax(array(
'url'=> CController::createUrl("result/ajaxIndex"),
'type'=>'post',
'data'=> array('offset'=>'js: counter()'),
'replace'=> '#ajax-result-grid',
))
?>
}
</script>
View - _ajaxIndex.php
<?php
/* @var $model Result */
?>
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'ajax-result-grid',
'dataProvider'=>$model->search(),
'columns'=>array(
array(
'header'=>Yii::t('strings','No.'),
'value'=> $model->offset.' + $row+1',
'htmlOptions'=>array('style'=>'width:50px;'),
),
array(
'header'=>Yii::t('strings','team_name'),
'name'=>'team_id',
'value'=>'$data->team->name'
),
array(
'header'=>Yii::t('strings','value'),
'name'=>'value',
'value'=>'$data->value'
),
),
)); ?>
<script type="text/javascript">
// This is need while the admins insert the results during this page is run.
summary = <?php echo $summary ?>;
rounds = Math.floor(summary / 10);
</script>
Yes, I think I don’t understand clearly the Ajax process in the Yii
