Is it possible or how ?

@MagePsycho:

if you want to create a filtrable admin grid, look at this article: http://www.about-magento.com/magento-admin-gridview-85

it’s how to do an admin grid. Good Chance

AFAIK, filtering doesn’t work for renderer column. If you want the column to be filterable then use normal column instead.

Thanks
MagePsycho

Very useful code and working fine but when go for filter then renderer column is disappear from the product grid means filter is not working on renderer column.

Please post the soution for this problem.

Thanks,

<?php

class Mage_Adminhtml_Block_Renderer_Customer extends Mage_Adminhtml_Block_Widget_Grid_Column_Renderer_Abstract
{

	public function render(Varien_Object $row)
    {
    	$model = Mage::getModel('customer/customer')->load($row->getCustomerId());

    	return  $model->getEmail();

    }

}

& in my rewritten grid I added the col as

[/code]
$this->addColumn('customer_email', array(
'header' => Mage::helper('sales')->__('Customer Email'),
'renderer' => 'adminhtml/renderer_customer',

));
[/cdoe]

I am having the email as desired. But these col is having a lot of trailing & leading spaces, dhue to which I think its not searchable
Can you suggest anything to remove those whitespaces? Thanks

Regards

->addAttributeToSelect(‘image’)

$this->addColumn(‘image’,
array(
‘header’=> Mage::helper(‘catalog’)->__(‘Has Image’),
‘width’ => ’100px’,
‘type’ => ‘number’,
‘index’ => ‘image’,
));

wondering someone could help.

heres what ive done so far

1. Ive created a new column in the orders grid in admin

2. ive created a new table called:

add_info

which has the following fields:

addinfo_id
entity_id (this is populated with the order entity id)
value (this is the value i want to display in the new column)

Im having trouble population the new column : (

please can someone guide me to how i can populate the new column with the data in the “value” field

thanks you soo much!!

Another solution:

You can extend the Column.php from app/code/local/Adminhtml/Block/Widget/Grid by adding to _getRendererByType() your new renderer.

    protected function _getRendererByType()
    {
        switch (strtolower($this->getType())) {
            case 'image':
                $rendererClass = 'adminhtml/widget_grid_column_renderer_image';
                break;
            default:
                $rendererClass = parent::_getRendererByType();
                break;
        }
        return $rendererClass;
    }

And then create your custom renderer (mine Image.php) into the app/code/local/Adminhtml/Block/Widget/Grid/Column/Renderer like you explained. (you should maybe add a function to get the full URL of your image if it comes from the products for example)
You can even create your custom filter app/code/local/Adminhtml/Block/Widget/Grid/Column/Filter in my case Image.php

Next, on your Grid.php instead of

'renderer'  => 'Mage_Adminhtml_Block_Catalog_Product_Renderer_Red',

write

'type'  => 'image',

Very good article and extremely useful!
