Yii + ajax : passing parameters to actions?

Hi everyone :)

I’m a complete newbie in PHP developping, i started like 2 weeks ago, and i have to realize a project.

I won’t say a lot about that project, but i have a problem realizing it.

in my mySQL DB, i have a table that contains a number of item that has been sold, a price, etc.

I would like to make statistics about those lines. So i have a model, controller, view etc for the lines, but it can’t render statistics.

i created thoses classes for my statistics. But i cant succeed to passes the selected parameters…

Here’s my code:

In the controller

	public function actionSelectStats(){



in my default view:

	<div class="form">

	<?php $form=$this->beginWidget('CActiveForm', array(



	)); ?>


	$article = new Article();

	$machine = new Machine();

	$personne = new Personnes();?>

		<div class="row">

		<?php echo $form->labelEx($article,'Choix de l\'article'); ?>


		//cette forme ci de dropdownliste permet d'ajouter un élément au début. Du coup, on n'est pas obligé

		//de sélectionner un article.?>

		<?php echo $form->dropDownList($article,'ID',CHtml::listData(Article::model()->findAll(), 'ID', 'libelle'),array('empty'=>Yii::t('fim','Tous les articles')));?>

		<?php echo $form->error($article,'article'); ?>


		<div class="row">

		<?php echo $form->labelEx($machine,'Choix de la machine'); ?>

		<?php echo $form->dropDownList($machine,'ID', CHtml::listData(Machine::model()->findAll(), 'ID', 'nomMachine'),array('empty'=>Yii::t('fim','Toutes les machines'))); ?>

		<?php echo $form->error($machine,'ID'); ?>


		<div class="row">

		<?php echo $form->labelEx($personne,'Choix de la personne'); ?>

		<?php echo $form->dropDownList($personne,'ID', CHtml::listData(Personnes::model()->findAll(), 'ID', 'prenom', 'nom'),array('empty'=>Yii::t('fim','Tout le monde'))); ?>

		<?php echo $form->error($personne,'ID'); ?>


		<?php echo "<input type=\"button\" value=\"valider\" onclick=\"showStats()\">" ;?>


	<?php $this->endWidget(); ?>

my javascript:

function showStats(){

	if (window.XMLHttpRequest){				// code for IE7+, Firefox, Chrome, Opera, Safari

		xmlhttp=new XMLHttpRequest();

	}else{									// code for IE6, IE5

		xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");



		if (xmlhttp.readyState==4){








and the selectStats.php works fine, nothing to see there.

So, i know that this code won’t ever passes the needed parameters. But i already tried everything, and i can’t figure out how to do that. I don’t even know if i’m following a good path.

Right now the only think i succeed to do is listing ALL the lines of my DB on my view. Ho yeah, in my view if i do:

<?php echo "<input type=\"button\" value=\"valider\" onclick=\"showStats($var1, $var2, $var3)\">" ;?>

the $var* are evaluated when the page is loaded and that won’t work. I did not figure out how to retrieve the parameters from my form?

Can anyone help me?

PS: sorry for my poor english, that’s not my mother language ;)

take a look on yii playground, here

The example uses CHtml::ajaxLink and CHtml::ajaxButton objects.
