Viewing product shows Call to a member function getId() on a non-object

[pwz2000]

When I go to view a product, I am seen with this error:

Fatal error: Call to a member function getId() on a non-object in /chroot/home/mpgautop/mpgautoparts.com/html/app/code/core/Mage/Catalog/Block/Category/View.php on line 43

Here are lines 42-47:

        if ($headBlock = $this->getLayout()->getBlock('head')) {
			$cat_id = $this->getCurrentCategory()->getId();
			$category = Mage::getModel('catalog/category')->getCurrentCategory()->getId();            
            if ($title = $category->getMetaTitle()) {
                $headBlock->setTitle($title);
            }

Does someone know of a fix for this? As I keep getting errors for line 43 and 44.

Hi,

You could rewrite the code as follows which will get around the error.. hopefully it still performs as you expect it too:

if ($headBlock = $this->getLayout()->getBlock('head')) {
    $currentCategory = $this->getCurrentCategory();
    if($currentCategory) {
        $cat_id = $currentCategory->getId();
        $category = Mage::getModel('catalog/category')->load($cat_id);           
        if ($title = $category->getMetaTitle()) {
            $headBlock->setTitle($title);
        }
    } else {
        // Cannot locate current category... 
        // Add some fallback code here?
        // e.g. $headBlock->setTitle('Default Title');
    }
}
