        <Easylife_Meta>

            <codePool>local</codePool>

            </depends>

        </Easylife_Meta>

    </modules>

</config>

app\code\local\Easylife\Meta\etc

Create config.xml

<?xml version="1.0"?>

<config>

    <modules>

        <Easylife_Meta>

            <version>0.0.1</version>

        </Easylife_Meta>

    </modules>

    <global>

        <models>

            <easylife_meta>

                <class>Easylife_Meta_Model</class>

            </easylife_meta>

        </models>

    </global>

    <adminhtml>

        <events>

    <catalog_product_save_before>

        <observers>

            <create_name>

                <class>easylife_meta/observer</class>

                <method>createName</method>

            </create_name>

        </observers>

    </catalog_product_save_before>

</events>

    </adminhtml>

</config>

\app\code\local\Easylife\Meta\Model

Create File Observer.php

<?php

class Easylife_Meta_Model_Observer

{

    public function createName($observer)

    {

        

        $product = $observer->getEvent()->getProduct();

        

        

      

      

       $data = $observer->getEvent()->getCategory();

       

       

        $product_category_id = $product['category_ids'];

        $productColor = $product->getWeight('weight');

        $productsizing = $product->getAttributeText('sizing');

        

       if (!empty($product_category_id)) {

        

        if (in_array("9", $product_category_id)){ // Here 9 in My Category ID

            

            $productSku = $productColor." ".$productsizing;

            $product->setName($productSku);

            

        }

        

        }

    }

}

Here You can generate name for particular category. you can also change all product remoce if

contion  $product->setName($productSku); set here your value. here 9 is my category

you can check your category id then check it.
