Updating in bulk with Massactions
When creating our base grid block, we defined a function called
_prepareMassactions(), which provides an easy way of manipulating
multiple records from the grid. In our case, for now, let's just implement
a mass delete action. Perform the following steps to do so:
Chapter 5
1. Open the registry grid block Grid.php, which can be found at app/code/
local/Mdg/Giftregistry/Block/Adminhtml/Registries/.
2. Replace the _prepareMassaction() function with the following code:
protected function _prepareMassaction(){
$this->setMassactionIdField('entity_id');
$this->getMassactionBlock()->
setFormFieldName('registries');
}
$this->getMassactionBlock()->addItem('delete', array(
'label' => Mage::helper
('mdg_giftregistry')->__('Delete'),
'url' => $this->getUrl('*/*/massDelete'),
'confirm' => Mage::helper
('mdg_giftregistry')->__('Are you sure?')
));
return $this;
The way mass actions work is by passing a series of selected IDs to our specified
controller action; in this case, the massDelete() action will add code to iterate
through the registry collection and delete each of the specified registries. Perform
the following steps:
1. Open the GiftregistryController.php file, which can be found at the
location app/code/local/Mdg/Giftregistry/controllers/Adminhtml/.
2. Replace the blank massDelete() action with the following code:
…
public function massDeleteAction()
{
$registryIds = $this->
getRequest()->getParam('registries');
if(!is_array($registryIds)) {
Mage::getSingleton('adminhtml/session')->
addError(Mage::helper('mdg_giftregistry')->
__('Please select one or more registries.'));
} else {
try {
