Cannot access id field with model?

Hi, I have a model where I'm trying to access the 'id' field. For example, I have the following code:

PHP Code:


			
<?php

class Animal extends Zend_Db_Table {
    
      protected $_name = 'animals';

      public function previousAnimal() {

         $animal = new Animal();
       $where = $animal->getAdapter()->quoteInto( 'id > ?', $this->id );  //  Error on:  $this->id
         $orderBy = 'id DESC';
         $previousAnimal = $animal->fetchAll( $where, $orderBy, 1 );

       return $previousAnimal;    
 
      }


      public function nextAnimal() {

      $animal = new Animal();
      $where = $animal->getAdapter()->quoteInto( 'id < ?', $this->id ); // Error on:  $this->id
      $orderBy = 'id ASC';
      $nextAnimal = $animal->fetchAll( $where, $orderBy, 1 );

      return $nextAnimal;

      }

}

?>

At this time, I'm getting the following message:

Undefined property Animal::$id

How does one define the properties of a model?

Thanks in advance,

-Conrad

In this case Animal is a table class, and therefore it doesn't have any properties.
However, you can fetch rows from it and access their properties respectively.
$this->id doesn't make sense to me. What exactly are you trying to achieve?
