problem with object, simpleXML in session

[bliiink]

i have a class which receive xml data. The class will store the xml data into variables using simpleXML.

The problem is when i store the class in session, the value of the variables is lost.

class file.

class userProfileQuestionObject
{
private $total;
private $name = array();
private $value = array();
private $type = array();

public function setQuestionArray($valueName,$valueValue,$valueType)
{
$this->name[$this->total] = $valueName;
$this->value[$this->total] = $valueValue;
$this->type[$this->total] = $valueType;

$this->total = $this->total+1;
}
function initialize($xmlResult)
{
$this->total = 0;
$sxml = simplexml_load_string($xmlResult);
for($i=0;$i<($sxml->rowAmount);$i++)
{
$this->setQuestionArray($sxml->record->element->fields->name[$i],$sxml->record->element->fields->value[$i],$sxml->record->element->fields->type[$i]);
}
$sxml = NULL;
}

function getName()
{
return $this->name;
}
function getValue()
{
return $this->value;
}
function getType()
{
return $this->type;
}
function getTotal()
{
return $this->total;
}

}

file using the class

include("userProfileQuestionObject.php");
$qo = new userProfileQuestionObject();
$qo->initialize($xmldata);

session_start();
$_SESSION['userProfileQuestionObject'] = $qo;

---

another file 2

include("classes/userProfileQuestionObject.php");

session_start();
$qo = $_SESSION['userProfileQuestionObject'];

$name = $qo->getName();

echo $name[0];

result .. echo will ouput nothin.

can anyone help? I appreciate it very much.
thank you.

Lack of XML notwithstanding, I have to say it works for me. Are you sure the data is getting into to the object in the first place? Has looking at the saved session data turned up any clues?

[bliiink]

hi,
if i print_r the object in session... i got these

---

userProfileQuestionObject Object ( [total:private] => 2 [name:private] => Array ( [0] => SimpleXMLElement Object ( [0] => userid ) [1] => SimpleXMLElement Object ( [0] => nama ) ) [value:private] => Array ( [0] => SimpleXMLElement Object ( [0] => apa apa yg display ) [1] => SimpleXMLElement Object ( [0] => nama nak display ) ) [type:private] => Array ( [0] => SimpleXMLElement Object ( [0] => text ) [1] => SimpleXMLElement Object ( [0] => text ) ) )

---

then if i print_r the object after i
$qo = $_SESSION['userProfileQuestionObject'];
print_r($qo);

in another file 2.. i got these

....................

userProfileQuestionObject Object ( [total:private] => 2 [name:private] => Array ( [0] => SimpleXMLElement Object ( ) [1] => SimpleXMLElement Object ( ) ) [value:private] => Array ( [0] => SimpleXMLElement Object ( ) [1] => SimpleXMLElement Object ( ) ) [type:private] => Array ( [0] => SimpleXMLElement Object ( ) [1] => SimpleXMLElement Object ( ) ) )

---

notice that the diff is

---

from the 1st print_r : Array ( [0] => SimpleXMLElement Object ( [0] => userid )

from the 2nd print_r : Array ( [0] => SimpleXMLElement Object ( )

---

the value in simpleXMLElement is gone.

this is my sample xml data

---

<result>
module>user_profile</module>
type>def</type>
<rowAmount>2</rowAmount>
<record><element><fields>
<name>userid</name>
<value>apa apa yg display</value>
<type>text</type>
<name>nama</name>
<value>nama nak display</value>
<type>text</type>
</fields></element></record>
</result>

---

really need anyone to help me, i have been trying to solve this for 3 weeks.

thanks in advanced.

Well, I looked at the saved session data and none of the saved SimpleXML objects are getting saved. In the absence of a proper answer off the top of my head, you can try serialize() to convert the object into a string and save it that way, and unserialize() to convert it back when you load it in again.

Or save the XML.

i tried serialize and unserialize it but the result is the same. If i saved the xml in session then the class is not really useful since i have to initialize the class everytime i wanna use it.
