I am trying to change the title of a new tab depending on the category ID of the product and I am getting this error message and i cant figure out why

Fatal error: Call to a member function getId() on a non-object in /home/senorehe/public_html/app/code/local/Mage/Catalog/Helper/Data.php

I know it is telling me what the problem is but i dont know why it is occurring as it works on my test server. This is my code which i have in Mage/Catalog/Helper/Data.php

 public function getTabName(){
    $currentCategoryId = Mage::registry('current_category')->getId(); 

    if ($currentCategoryId == '1168' || $currentCategoryId == '1169' || $currentCategoryId == '1174' || $currentCategoryId == '1175' || $currentCategoryId == '1177') 
        return 'Size Guide'; 
    return $this->__('Data Sheets');

and this is the local.xml code

<action method="addTab" translate="title" module="catalog" >    
    <title helper="Catalog/getTabName" />

Instead of

$currentCategoryId = Mage::registry('current_category')->getId();

use this

$currentCategoryId = null;
if (Mage::registry('current_category')) {
     $currentCategoryId = Mage::registry('current_category')->getId();

  • Thank you, i will accept when it lets me. So what was the reason for the error and why did your fix work, just so i know for the future – Adam Allen Nov 24 '15 at 13:09
  • sometimes, depending on the url Mage::registry('current_category') returns null. – Marius Nov 24 '15 at 13:13
