Magento : How to Rename the Attribute Code?

Connect to your Magento database using your favourite database GUI (PHPMyAdmin, HeidiSQL, MySQL Workbench, etc.).

Caution: backup your database

Go to the table eav_attribute and edit the column attribute_code. You can rename the attribute code here.

Once you have renamed the attribute code in the database, go to the Magento admin and re-index (System > Index Management) all indexes.

Magento : Get Logged In Customer’s Group ID

<?php
/* Check if customer is logged in */
$isLoggedIn = Mage::getSingleton('customer/session')->isLoggedIn();
/* If customer is logged in */
if($isLoggedIn) :
    /* Get the logged in customer's group ID */
    $customerGroupId = Mage::getSingleton('customer/session')->getCustomerGroupId();
    /* Check if the logged in customer's group ID matches with the ID you are after */
    /* Customer group IDs are listed against each group under Admin > Customers > Customer Groups */
    if($customerGroupId == 3) :
        echo 'Welcome Retailer';
    endif;
endif;
?>

You can also write static blocks or custom variables to contain group specific information. You can name the static block identifier based on the $customerGroupId and retrieve it on the front end.

if(Mage::getModel('cms/block')->load('static-block-identifier')->getIsActive()) : 
    echo Mage::app()->getLayout()->createBlock('cms/block')->setBlockId('static-block-identifier')->toHtml(); 
endif; 

?>

WordPress : Remove Version Query Strings From JavaScript JS and CSS Stylesheet Files

In efforts to increase the performance of a WordPress website, tools like Google Page Speed and Yahoo YSlow may direct you to remove the query string from JavaScript and CSS files. Most scripts and stylesheets called by WordPress include a query string identifying the version. This can cause issues with caching and such, which will result in less than optimal load times.

For instance, jQuery.js may show up like:

/wp-includes/js/jquery/jquery.js?ver=1.4.2


there is a very simple function that can be added to remove all query strings from script and css files.
In your theme’s function file (Appearance > Editor > Functions.php), add the following code before the closing PHP tag (%>) at the bottom of the file:


function _remove_script_version( $src ){
$parts = explode( '?', $src );
return $parts[0];
}
add_filter( 'script_loader_src', '_remove_script_version', 15, 1 );
add_filter( 'style_loader_src', '_remove_script_version', 15, 1 );


Hope you find this helpful!
