getting problem in add custom product attribute in PDF invoice magento1.9 [closed]

Question

I am trying to add custom attribute "publisher name" below product name in PDF invoice. Publisher is a custom attribute created by me.

I have copied

app/code/core/Mage/Sales/Model/Order/Pdf/Items/Invoice/Default.php

to

app/code/local/Mage/Sales/Model/Order/Pdf/Items/Invoice/Default.php

And have added some code in default.php but this is not working properly. It is showing attribute id like 250,251 in the pdf but I want it to show publisher name

I add following code in default.php

$Publisher = $this->getPublisherValue($item);

 $lines[1][] = array(
        'text'  => Mage::helper('core/string')->str_split($Publisher, 35),
        'feed'  => 35
    );


private function getPublisherValue($item)
    {
        $prod = Mage::getModel('catalog/product')->load($item->getProductId());

        if(($return_publisher = $prod->getPublisher()))
            return $return_publisher;
        else
            return 'N/A';
   }

Answer 1

I guss that publisher is text type attribute

if($prod->getId()){
 /* if  check product is exit   */ 
 /* check getPublisher  value is null or not */
if(!is_null($prod->getPublisher()))
    return $return_publisher;
    else
    return $prod->getPublisher();



else{
return 'N/A';
}

If it dropdown attribute then use below code to get publisher label

$product->getResource()->getAttribute('publisher')->getFrontend()->getValue($product);
