(beginner) database query in dropdownlist in form

[eluser]rijobo[/eluser]
Hello,

I would like to create a dropdown list from my database, but i get the error:

A PHP Error was encountered
Severity: Notice

Message: Undefined variable: soort

Filename: views/product_toevoegen.php

Line Number: 54

What do I do wrong?

This is what I do:

In my controller:

Code:

$soort = $this->Productupload->SelectieSoort();
$this->load->view('product_toevoegen', $soort);

My model:

Code:

function SelectieSoort(){
    $this->db->select('soort');
    $soort = $this->db->get('soort');
    return $soort;
}

My view (form):

Code:

<h5>Soortlijst</h5>
&lt;?php echo form_dropdown('soort', $soort, ''); ?&gt;
