Storing array in sessions - php

Question

I am trying to store some data as an array in the session but the function does not seem to be working.it does not throw any error but every time i add data to it, it just overwrites the previous data. I am using yii and here is the action
public function actionStoreProducts($name)
{
$name=trim(strip_tags($name));
if(!empty($name))
{
if(!isset(Yii::app()->session['_products']))
{
Yii::app()->session['_products']=array($name);
echo 'added';
}
else
{
$myProducts = Yii::app()->session['_products'];
$myProducts[] = $name;
Yii::app()->session['products'] = $myProducts;
echo 'added';
}
}
Can anyone suggest me how can i achieve the desired result?

Answer 1

Please correct your code like this .
public function actionStoreProducts($name) {
$name = trim(strip_tags($name));
if (!empty($name)) {
if (!isset(Yii::app()->session['_products'])) {
Yii::app()->session['_products'] = array($name);
echo 'added';
} else {
$myProducts = Yii::app()->session['_products'];
$myProducts[] = $name;
Yii::app()->session['_products'] = $myProducts;
echo print_r(Yii::app()->session['_products']);
echo 'added';
}
}
}

Answer 2

session property read-only
i think the correct aproach is :
function actionStoreProducts($name) {
$session = new CHttpSession; //add this line
$session->open(); //add this line
$name = trim(strip_tags($name));
if (!empty($name)) {
if (!isset(Yii::app()->session['_products'])) {
$session->add('_products', array($name)); //replace this line
echo 'added';
} else {
$myProducts = Yii::app()->session['_products'];
$myProducts[] = $name;
$session->add('_products', $myProducts); //replace this line
echo 'added';
}
}
}

Answer 3

first get an variable into $session['somevalue'] ,then sore in array variable, Use Like IT:-
$session = new CHttpSession;
$session->open();
$myval = $session['somevalue'];
$myval[] = $_POST['level'];
$session['somevalue'] = $myval;
