class problem

I get an error:
Fatal error: Call to a member function on a non-object in

It s telling me that $objImage: is not an object. Although i made it an
object in the constructor. Someone can help me out?

kind regards
Stijn


The errorline is: $objImage->createImage($index);

include_once('class.UploadPicture.php');
class Album
{
var $objImage;

function Album($width) //constructor
{
$objImage = new UploadPicture($width,'');
}

function putImage($index)
{
$objImage->createImage($index);
}
}
?>

Try to print out the $objImage.
The problem is probably on the:
*$objImage = new UploadPicture($width,'');*

The object is created correctly but seems to be unknown in the putImage
function.
When I do

function Album($width) //constructor
{
$this->setCurrentPeriod();
$objImage = new UploadPicture($width,'');
$objImage->createImage(0);
}

It works

but when I do

function Album($width) //constructor
{
$this->setCurrentPeriod();
$objImage = new UploadPicture($width,'');
$this->putImage(1);
}

function putImage($index)
{
$objImage->createImage(1);
}

I get the error: Fatal error: Call to a member function on a non-object

Someone knows what the problem is?
kind regards
Stijn

Yeah! I'm stupid! This is a tivial error. You must referentiate always
your member variables with $this. So your class is:
class Album
{
var $objImage;

function Album($width) //constructor
{
$this->objImage = new UploadPicture($width,'');
}

function putImage($index)
{
$this->objImage->createImage($index);
}
}

see you.
