ZendFramework: Object of class could not be converted to string

Question

Hey guys I have a form with one input box, when I submit the form I get the following error:

Catchable fatal error: Object of class Application_Model_DbTable_Comments could not be converted to string in /Users/Ric/Sites/MN/library/Zend/Db/Statement/Pdo.php on line 228 Call Stack: 0.0002 657600 1. {main}() /Users/Ric/Sites/MN/public/index.php:0 0.0323 6224344 2.

Here is the form:

<?php

class Application_Form_Comment extends Zend_Form
{

public function init()
{
    $this->setName('comment');
    $id = new Zend_Form_Element_Hidden('id');
  $id->addFilter('Int');
        $comment = new Zend_Form_Element_Text('comment');
        $comment->setLabel('Comment:')
            ->setRequired(true)
            ->addFilter('StripTags')
            ->addFilter('StringTrim')
            ->addValidator('NotEmpty');
    $submit = new Zend_Form_Element_Submit('submit');
    $submit->setAttrib('id', 'submitbutton');
    $this->addElements(array($id, $comment, $submit));
        }
    }

Here is the controller:

public function indexAction()
    {
       //action for the comments submission
       $form = new Application_Form_Comment();
       $form->submit->setLabel('Comment');
       $this->view->form = $form;
       if ($this->getRequest()->isPost()) {
        $formData = $this->getRequest()->getPost();
        if ($form->isValid($formData)) {
            $comment = $form->getValue('comment');
            $comment = new Application_Model_DbTable_Comments();
            $comment->addComment($comment);
            $this->_helper->redirector('index');
        } else {
            $form->populate($formData);
        }
    }
}

The Model:

class Application_Model_DbTable_Comments extends Zend_Db_Table_Abstract {

protected $_name = 'comments';

public function addComment($comment) {
    $data = array(
        'comment' => $comment,
        );
    $this->insert($data);
}

}

The view:

<div id="comments">
    <?php echo $this->form; ?>
</div>

Thanks

Rik

you problem is here

$comment = $form->getValue('comment');
$comment = new Application_Model_DbTable_Comments();
$comment->addComment($comment);

change it to

$comment = new Application_Model_DbTable_Comments();
$comment->addComment($form->getValue('comment'));
