Magento : MassDelete & Status action in admin grid

Consider Package: Bd, Module : Test & Model : Test

1.Override _prepareMassaction() method in Grid.php with following code

protected function _prepareMassaction()
    {
        $this->setMassactionIdField('test_id');
        $this->getMassactionBlock()->setFormFieldName('test');

        $this->getMassactionBlock()->addItem('delete', array(
             'label'    => Mage::helper('test')->__('Delete'),
             'url'      => $this->getUrl('*/*/massDelete'),
             'confirm'  => Mage::helper('test')->__('Are you sure?')
        ));

        $statuses = Mage::getSingleton('test/status')->getOptionArray();

        array_unshift($statuses, array('label'=>'', 'value'=>''));
        $this->getMassactionBlock()->addItem('status', array(
             'label'=> Mage::helper('test')->__('Change status'),
             'url'  => $this->getUrl('*/*/massStatus', array('_current'=>true)),
             'additional' => array(
                    'visibility' => array(
                         'name' => 'status',
                         'type' => 'select',
                         'class' => 'required-entry',
                         'label' => Mage::helper('test')->__('Status'),
                         'values' => $statuses
                     )
             )
        ));

public function massDeleteAction() {
        $testIds = $this->getRequest()->getParam('test');
        if(!is_array($testIds)) {
   Mage::getSingleton('adminhtml/session')->addError(Mage::helper('adminhtml')->__('Please select item(s)'));
        } else {
            try {
                foreach ($testIds as $testId) {
                    $test = Mage::getModel('test/test')->load($testId);
                    $test->delete();
                }
                Mage::getSingleton('adminhtml/session')->addSuccess(
                    Mage::helper('adminhtml')->__(
                        'Total of %d record(s) were successfully deleted', count($testIds)
                    )
                );
            } catch (Exception $e) {
                Mage::getSingleton('adminhtml/session')->addError($e->getMessage());
            }
        }
        $this->_redirect('*/*/index');
    }

    public function massStatusAction()
    {

        } else {
            try {
                foreach ($testIds as $testId) {
                    $test = Mage::getSingleton('test/test')
                        ->load($testId)
                        ->setStatus($this->getRequest()->getParam('status'))
                        ->setIsMassupdate(true)
                        ->save();
                }
                $this->_getSession()->addSuccess(
                    $this->__('Total of %d record(s) were successfully updated', count($testIds))
                );
            } catch (Exception $e) {
                $this->_getSession()->addError($e->getMessage());
            }
        }
        $this->_redirect('*/*/index');
    }

Object Expected error in Internet Explorer

This error usually happens in the following scenario. An HTML file contains an inline JavaScript to load remote.js and call a function in remote.js

<script type="text/javascript">
//<![CDATA[
    Event.observe(window, 'load', function() {
        product_zoom = new Product.Zoom('image', 'track', 'handle', 'zoom_in', 'zoom_out', 'track_hint');
    });
//]]>
</script>

And in the file remote.js:
remoteFunction code.....


You would expect the output in this order:

    Before loading remote.js
    After loading remote.js
    In remote function

IE gives an error message "Object Expected" because it calls the function remoteFunction() prematurely. It calls before loading the file remote.js, which contain the declaration of remoteFunction(). This is another unexpected behavior from IE. Fortunately, it can be corrected by adding the attribute defer="defer" to second script invocation. This will specifically prevent IE from executing in order to give a correct output. Other browsers are not affected by the change.

Magento: Tag Url Rewrite and Generate

Rewrite the tag/tag model and override the getTaggedProductsUrl() with the following code
public function getTaggedProductsUrl()
{
    $fullTargetPath = Mage::getUrl('tag/product/list', array(
        'tagId' => $this->getTagId(),
        '_nosid' => true
    ));
    $targetPath = substr($fullTargetPath, strlen(Mage::getBaseUrl()));
    $rewriteUrl = Mage::getModel('core/url_rewrite')->loadByIdPath($targetPath);
    if ($rewriteUrl->getId()) {
        return $rewriteUrl->getRequestPath();
    }
    return $fullTargetPath;
}

Magento : Define Global, Website, Store, Store View

    Global: This refers to the entire installation.
    Website: Websites are ‘parents’ of stores.  A website consists of one or more stores. Websites can be set up to share customer data, or not to share any data
    Store (or store view group): Stores are ‘children’ of websites.  Products and Categories are managed on the store level.  A root category is configured for each store view group, allowing multiple stores under the same website to have totally different catalog structures.
    Store View: A store needs one or more store views to be browse-able in the front-end.  The catalog structure per store view will always be the same, it simply allows for multiple presentations of the data in the front.  90% of implementations will likely use store views to allow customers to switch between 2 or more languages.
