use array in another class

[itsme85]

Hello,

I am trying to make my own form handler.

This is a part of my code in my form class.

if ($attrib['elements'])
		{
			$this->elements = $attrib['elements'];
			$this->field = new PHP_Myelement($this->elements);
			$this->field->runElements();
			if (method_exists($this->field))
			{
			throw new Exception("Method does not exist");
			}
		}

	if (empty($this->elements))
	{
		throw new Exception("Set form elements");
	}

I want to get the $this->elements array in my element class.
With the following code.

class Element
{
	public function __contruct($elements=null)
	{
		if (is_array($elements)) 
		{
            $this->setElements($elements);
		}

	if (empty($this->elements))
	{
		throw new Exception("Set form elements");
	}
}

//Set form elements
public function setElements($elements=array())
{
	if ($elements['username'])
	{
		$this->element = $elements['username'];
		$this->elementOptions($this->element);
	}

	if (empty($this->element))
	{
		throw new Exception("No element ".$this->element."");
	}	
}

public function elementOptions($element=array())
{
	if ($element['type'])
	{
		$this->type = $element['type'];

	}

	if (empty($this->type))
	{
		throw new Exception("No type");
	}
}

public function runElements()
{
	$this->form = "".$this->type."";
}

public function __toString()
{
	return $this->form;
}
}

Can someone tell me why my code isn't output the $this->form? It works when I use a simple string. And how can I debug this code. Because, the Exception code doesn't work in my element class.

Thanks in advance.
