Passing PHP Variable to controller and get it back - php

Question

I have a variable and I want to update the value in the controller and render a part of the page based on the value.
This works very well in the first time but the variable doesn't get the value, stay with the first. Here my code:
Model:
public function actionCreate()
{
$model=new CadTeste;
$teste=1;
if(isset($_POST['CadTeste']))
{
$model->attributes=$_POST['CadTeste'];
if($model->save())
$this->redirect(array('view','id'=>$model->icd_teste));
}
$this->render('create',array(
'model'=>$model,
'teste'=>$teste,
));
}
Form:
<div id="data">
<?php $this->renderPartial('_ajaxContent', array('teste'=>$teste)); ?>
</div>
<?php
echo CHtml::ajaxSubmitButton('Alterar Num',CController::createUrl('CadTeste/UpdateAjax'),
array('type'=>'POST',
'data' => array('teste'=> $teste),
'update' => '#data'
)
); ?>
The Controler
public function actionUpdateAjax()
{
$teste = $_POST['teste'];
$teste += 10;
$this->renderPartial('_ajaxContent', array('teste'=>$teste), false, true);
}
And the _ajaxContent
<?php echo $teste; ?>
Every time I click on the button I get the value "11" instead of "11, 21, 31, 41".
How can I do that? Should I change the value every time in the controller?

Try Using Sessions . This Works for me
View File
<?php Yii::app()->session['teste']=$teste ?>
<div id='data'>
<?php $this->renderPartial('_ajaxContent', array('teste'=>$teste)); ?>
</div>
<?php
echo CHtml::ajaxSubmitButton('Alterar Num',$this->createUrl('CadTeste/UpdateAjax'),
array('type'=>'POST',
// 'data' => array('teste'=> $teste),
'update' => '#data'
)
); ?>
Your Controller
public function actionUpdateAjax()
{
$teste = Yii::app()->session['teste'];
$teste += 10;
$this->renderPartial('_ajaxContent', array('teste'=>$teste));
unset(Yii::app()->session['teste']);
Yii::app()->session['teste']=$teste;
}
And Your Model As it Is
public function actionCreate()
{
$model=new CadTeste;
$teste=1;
if(isset($_POST['CadTeste']))
{
$model->attributes=$_POST['CadTeste'];
if($model->save())
$this->redirect(array('view','id'=>$model->icd_teste));
}
$this->render('create',array(
'model'=>$model,
'teste'=>$teste,
));
}
Not sure if this is your problem, but renderPartial() does not play well with AJAX. It is a known Yii issue:

Try using this for the view:
<?php
echo CHtml::ajaxSubmitButton('Alterar Num',CController::createUrl('CadTeste/UpdateAjax',array('teste'=>$teste)),
array('type'=>'POST',
'update' => '#data'
)
); ?>
This for the controller:
public function actionUpdateAjax($teste)
{
$teste += 10;
$this->renderPartial('_ajaxContent', array('teste'=>$teste));
}
This way you can POST to action/ajaxupdate/teste/1
Its called Parameter Binding, the parameter in $teste is populated automatically from the url, if it's not present, it will give you an error. (You could put a default value $teste=1 to make it optional)
