Adding new mass action to admin grid in Magento

December 5, 2011  |  6 Comments  |  by Raj (MagePsycho)  |  Latest, Magento


You know Magento allows to have mass action on the selected grid listing items.
The purpose of mass action is obvious that it allows to have mass operation on the selected rows at once. Some popular mass action are: Delete, Update Status etc.

Mass Action (Sales > Order Grid)

This is an often requirement that you may need to add new mass action to sales, customer, products etc. So here i will be sharing the different ways for adding new mass action:

1. By Extending the Admin Grid:

For example purpose we will be using Sales Order Grid.
1.1 Use the following code in config.xml of your module (for example: app/code/local/MagePsycho/Newmodule/etc)


1.2 Create a file: app/code/local/MagePsycho/Newmodule/Block/Sales/Order/Grid.php and paste the following code:

class MagePsycho_Newmodule_Block_Sales_Order_Grid extends Mage_Adminhtml_Block_Sales_Order_Grid
	protected function _prepareMassaction()
        // Append new mass action option 
            array('label' => $this->__('New Mass Action Title'), 
				  'url'   => $this->getUrl('newmodule/controller/action') //this should be the url where there will be mass operation

1.3 That’s all. This will show up the new mass action in the drop-down of Sales > Order Grid.
Note: One of the major drawback of this feature is the compatibility issue with other extension which are extending the same Sales Order Grid class.

2. Using event: core_block_abstract_prepare_layout_before

2.1 Use the following xml code in config.xml:


2.2 Create a Model file: app/code/local/MagePsycho/Newmodule/Model/Observer.php and paste the following code:

class MagePsycho_Newmodule_Model_Observer
    public function addMassAction($observer)
        $block = $observer->getEvent()->getBlock();
        if(get_class($block) =='Mage_Adminhtml_Block_Widget_Grid_Massaction'
            && $block->getRequest()->getControllerName() == 'sales_order')
            $block->addItem('newmodule', array(
                'label' => 'New Mass Action Title',
                'url' => Mage::app()->getStore()->getUrl('newmodule/controller/action'),

2.3 That’s all.
Note: This is more upgrade proof method because we are not extending any core class but using event-observer method.
It’s always a best practice to use event-observer method whenever/wherever possible.

Lastly, this is not the full working code, we have only tried to show how to add new mass action to the grid. The main mass operation on the selected items should be done in controller level which has been skipped from this article and can try of your own.

Thanks for reading.
Happy Coding!

    For the mentioned drawback.

    class SNH_ShipMailInvoice_Model_Observer
    public function addActions($observer)
    $block = $observer->getEvent()->getBlock();
    // Check if this block is a MassAction block
    if ($block instanceof Mage_Adminhtml_Block_Widget_Grid_Massaction) {
    // Check if we’re dealing with the Orders grid
    if ($block->getParentBlock() instanceof Mage_Adminhtml_Block_Sales_Order_Grid) {
    // The first parameter has to be unique, or you’ll overwrite the old action.
    $block->addItem(‘shipmailinvoice’, array(
    ‘label’ => Mage::helper(‘sales’)->__(‘Ship, Mail and Invoice’),
    ‘url’ => $block->getUrl(‘*/*/’),

    (ignore last comment, didnt read properly)

    Would you have an example of the ordercontroller changes?
    The main mass operation on the selected items should be done in controller level which has been skipped from this article and can try of your own.

    Also, somehow addMassaction is not working. But when I change to addActions it does work. Strange?

    What is to be enter in ‘controller’ and ‘action’ field in geturl() function ?

  • Anders

    Thanks for a nice guide. I successfully added the extra bulk option using method 2, but I can’t seem to get the controller to work. Would anyone care to explain how this is done? Thanks, and marry christmas.

    really helped me set up a mass action. observer puts it at top of the list with additem. can i put this at another location, or at the bottom? Of do I need to use another function instead of additem?

  • Lee

    I found this article really helpful.

    Is there a way to also add an action link to the end of each row using only an observer?
