Adding thumbnail image for custom column in magento admin grid

Sometimes we  need to show thumbnail image for custom attribute in magento admin grid. As we might know it is little tricky to add thumbnail image in a grid in magento admin. Here we’ve discussed the way how we can add thumbnail image.

1.  Firstly we have to add the following code snippet in _prepareColumns() function, in Grid.php(path: code/local/Packagename/Modulename/Block/Adminhtml/Modulename/Grid.php). Here we use the local path you can use community.

<?php
$this->addColumn('modulenameimage', array(
'header' => Mage::helper('modulename')->__('Image'),
'align' => 'left',
'index' => 'modulenameimage',
'renderer' => 'modulename/adminhtml_modulename_renderer_image',
'width' => '107'
));
?>

Note: Here modulenameimage is the custom attribute.

2. Here we can see that a renderer block(adminhtml_modulename_renderer_image), so now our task is to create that block in Packagename_Modulename_Block_Adminhtml_Modulename_Renderer_Image file as below:

<?php
class Packagename_Modulename_Block_Adminhtml_Modulename_Renderer_Image extends Mage_Adminhtml_Block_Widget_Grid_Column_Renderer_Abstract {

public function render(Varien_Object $row) {
$html = '<img ';
$html .= 'id="' . $this->getColumn()->getId() . '" ';
$html .= 'width="' . $this->getColumn()->getWidth() . '" ';
$html .= 'src="' . Mage::getBaseUrl("media") . 'images/' . $row->getData($this->getColumn()->getIndex()) . '"';
$html .= 'class="grid-image ' . $this->getColumn()->getInlineCss() . '"/>';
return $html;
}
}
?>

These are all you need to do to show thumbnail image in grid view. Now you can the grid for that particular module and see the image there. You can change the custom column, image path, width, height as you desire.

Troubleshooting in UBUNTU

Today I faced a problem in UBUNTU 11.04. When I try to open a browser as a root from terminal, in terminal these error show

Initializing nautilus-gdu extension
** (nautilus:2158): WARNING **: Failed to get the current CK session: GDBus.Error:org.freedesktop.ConsoleKit.Manager.GeneralError: Unable to lookup session information for process ’2158′

Error No such file or directoryPlease ask your system administrator to enable user sharing.

I did not get any clue, whatever I got I delete a user, which I delete from ubuntu user/account option.

After searching few times I got the recovery, since within a account there are group, group id, and files, these error happened.

The recovery is:

sudo groupadd sambashare
sudo adduser `whoami` sambashare

Background image for magento email template

Hi, I read a thread ‘http://www.magentocommerce.com/boards/view/viewthread/218412/#’, for email template in magento, Someone post this for help, but unfortunately I can’t reply there [captcha was not working].
So I share the solution here,
<div style=”background-image:url({{skin url=’images/template_bg.gif’}})  no-repeat;”>
Here the url is http://127.0.0.1/magento/skin/adminhtml/default/default/images/template_bg.gif, for my localhost.

Get home page url or store url in magento

We can use one of the following to access home page in magento.

[php]
echo Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_WEB);

echo Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_LINK);
[/php]
or

[php]
echo Mage::app()->getStore()->getHomeUrl();
[/php]

We can also use the [html] {{store url=”}}[/html] in static block or CMS page to access home page.

Configurable product options in Category list page in magento

Often we may need to show product’s option in category list page, for example a product may contain a option ‘size’ where the values are small, medium and large and price may different for different options. We can display these options in category list page like product view page. This can be done as below:

[php]
$_productCollection=$this->getLoadedProductCollection();
foreach ($_productCollection as $_product):
$product = Mage::getModel(‘catalog/product’)->setStoreId(Mage::app()->getStore()->getId());
$xml = "";
$hasAtts = 0;
$pass = 0;
$productType = $product->getTypeId();
if($productType == "configurable")
{
$attValConfig = $product->getTypeInstance(true)->setStoreFilter(Mage::app()->getStore(), $product)->getConfigurableAttributesAsArray($product);
if(sizeof($attValConfig)) {
$hasAtts++;
foreach($attValConfig as $attValConfigSingle)
{
echo "<select class=’cust_select’ name=’super_attribute[".$attValConfigSingle['attribute_id']."]’>";
foreach($attValConfigSingle['values'] as $attValConfigSingleVal) {
echo "<option value=’".$attValConfigSingleVal['value_index']."’>".$attValConfigSingleVal['label'].’ +’.Mage::helper(‘core’)->currency($attValConfigSingleVal['pricing_value'])."</option>";
}
echo "</select>";
}
}
}
endforeach;
[/php]

These code snippet shows the product’s options with prices.
