<p>Here is the simplest and best way to override META logics for product page in magento </p>
<p>copy <strong>/app/code/core/Mage/Catalog/Block/Product/View.php</strong>
to <strong>/app/code/local/Mage/Catalog/Block/Product</strong></p>
<p>and override <strong>function _prepareLayout()</strong>, my example goes bellow</p>
<pre><code>protected function _prepareLayout()
{
$this->getLayout()->createBlock('catalog/breadcrumbs');
$headBlock = $this->getLayout()->getBlock('head');
if ($headBlock) {
$product = $this->getProduct();
$title = $product->getMetaTitle();
// SEO values start
$categoryCollection = $product->getCategoryCollection();
foreach ($categoryCollection as $k) {
$topCategory = Mage::getModel('catalog/category')->load($k->getId());
break;
}
$brand = $product->getResource()->getAttribute('brand')->getFrontend()->getValue($product);
$shortDescription = $product->getShortDescription();
$suffix = Mage::getStoreConfig('design/head/title_suffix');
// SEO values end
if (!$title) {
$title = $product->getName() .' '.$brand. ' - '. $topCategory->getName() . $suffix;
}
$headBlock->setTitle($title);
$keyword = $product->getMetaKeyword();
$currentCategory = Mage::registry('current_category');
if ($keyword) {
$headBlock->setKeywords($keyword);
} elseif($currentCategory) {
$headBlock->setKeywords($product->getName());
}
$description = $product->getMetaDescription();
if (!$description) {
$description = $brand. ' '. $topCategory->getName() .'. '. $shortDescription;
}
$headBlock->setDescription( ($description) );
// var_dump($title);
// var_dump($description);
if ($this->helper('catalog/product')->canUseCanonicalTag()) {
$params = array('_ignore_category'=>true);
$headBlock->addLinkRel('canonical', $product->getUrlModel()->getUrl($product, $params));
}
}
return parent::_prepareLayout();
}
