[Shoaib_Fareedi]

I am creating an admin module with admin form but its gives an error when i save the form data. please have a look and check where i am wrong

Ii have following form fields

protected function _prepareForm()
    {
        $form = new Varien_Data_Form(array(
            'id' => 'edit_form',
            'action' => $this->getUrl('*/*/save'),
            'method' => 'post',
            ));

        $form->setUseContainer(true);
        $this->setForm($form);

        $helper = Mage::helper('optfirst_reviewmycompany');
        $fieldset = $form->addFieldset('display', array('legend' => $helper->__('Select Social Icons'),
                'class' => 'fieldset-wide'));

        $fieldset->addField('facebook', 'text', array(
            'name' => 'facebook',
            'label' => $helper->__('Facebook'),
            ));
        $fieldset->addField('google', 'text', array(
            'name' => 'google',
            'label' => $helper->__('Google'),
            ));
        $fieldset->addField('twitter', 'text', array(
            'name' => 'twitter',
            'label' => $helper->__('Twitter'),
            ));
        $fieldset->addField('linkedin', 'text', array(
            'name' => 'linkedin',
            'label' => $helper->__('Linkedin'),
            ));
        $fieldset->addField('yelp', 'text', array(
            'name' => 'yelp',
            'label' => $helper->__('Yelp'),
            ));


        if (Mage::registry('optfirst_reviewmycompany')) {
            $form->setValues(Mage::registry('optfirst_reviewmycompany')->getData());
        }

        return parent::_prepareForm();
    }

Here is my model configuration in config.xml

<models>
            <optfirst_reviewmycompany>
                <class>OptFirst_ReviewMyCompany_Model</class>
                <resourceModel>optfirst_reviewmycompany_resources</resourceModel>
            </optfirst_reviewmycompany>
            <optfirst_reviewmycompany_resources>
                <class>OptFirst_ReviewMyCompany_Model_Resources</class>
                <entities>
                    <review>
                        <table>optfirst_reviewmycompany_icons</table>
                    </review>
                </entities>
            </optfirst_reviewmycompany_resources>
        </models>

Following is my model:

class OptFirst_ReviewMyCompany_Model_Review extends Mage_Core_Model_Abstract
{
     public function _construct()
     {
         parent::_construct();
         $this->_init('optfirst_reviewmycompany/review');
     }
}

And finally here is my controller method to save the data:

 public function saveAction()
        {
        
        //$data = $this->getRequest()->getParams();
    if ( $data = $this->getRequest()->getParams() ) {
        
        print_r($data);
       
        $this->_getSession()->setFormData($data);
        $model = Mage::getModel('optfirst_reviewmycompany/review')->load(3);
        //$model = Mage::getModel('optfirst_reviewmycompany/review');
        print_r($model->getData());
        
        $id = $this->getRequest()->getParam('id');
        try {
            if ( $id ) {
                $model->load($id);
            }
            $model->addData($data);
            //saves data
            $model->save();

            $this->_getSession()->addSuccess(
                    $this->__('Data was saved'));

            $this->_getSession()->setFormData(false);

            if ( $this->getRequest()->getParam('back') ) {
                $params = array('id' => $model->getId());
                $this->_redirect('*/*/edit', $params);
            } else {
                $this->_redirect('*/*/list');
            }
        } catch ( Exception $e ) {
            $this->_getSession()->addError($e->getMessage());
            if ( $model && $model->getId() ) {
                $this->_redirect('*/*/edit', array(
                    'id' => $model->getId()
                ));
            } else {
                $this->_redirect('*/*/new');
            }
        }

        return;
    }

Help me in solving the issue.

Thanks!
