I'm trying to write a custom action to run off of an admin grid that I have built. Is it possible to send a value from a column in the grid to the controller via either get or post?

I've tried googling, but I cannot find a proper explanation for this anywhere. A link to an explanation of the column settings ('getter', 'type' etc.) would also be useful if this is available.

Add this code to your Grid.php:

        $this->addColumn('action',
            array(
            'header'    =>  Mage::helper('yourmodulename')->__('Action'),
            'width'     => '100',
            'type'      => 'action',
            'getter'    => 'getId',
            'actions'   => array(
                    array(
                            'caption'   => Mage::helper('yourmodulename')->__('Edit'),
                            'url'       => array('base'=> '*/*/edit'),
                            'field'     => 'id'
                    )
            ),
            'filter'    => false,
            'sortable'  => false,
            'index'     => 'stores',
            'is_system' => true,
    ));

That will build an "Edit" URL with the Id of the selected row as part of the URL. It will look something like <frontname>/<controllername>/edit/id/<value> where value is returned by the getter getId().

The getter field will execute any of the standard Magento magic getters, ie any attribute is gettable. So you could have getName or getProductUrl or getIsLeftHanded if you wanted and your controller can parse the attribute.

The controller can then retrieve that passed value using Mage::app()->getRequest()->getParam('attributename');

In terms of documentation/tutorials, have a read of this article on the website of @AlanStorm as it might help.

  • Thanks for your help, that's pretty much all I needed to know. I didn't realise you could use 'getter' to pick pretty much any attribute. – Geoff Apr 20 '11 at 12:27
  • The getter is new to me as well, but exactly what I needed. – Jim OHalloran Oct 04 '12 at 03:26
  • What if I want to get more than one getter means What if I want to pass multi parameter in URL which can't be access be using Mage::app()->getRequest()->getParam('attributename') – shashank Feb 02 '16 at 13:10

    Should I use getter=>array('attribute1',attribute2); – shashank Feb 02 '16 at 13:11
