I needed to import manufacturers list from oscommerce to magento and this is how i did it, not sure if there is an easy way to do this. Let me know if you know better way to do it.
Lets create a file (manufacturer.php) on the root of the magento installation path, and add below code and run the file. Code is self explanatory I guess :)
Step 1: app\etc\modules\Technooze_All.xml
<?xml version="1.0"?>
<config>
<modules>
<Technooze_Customer>
<active>true</active>
<codePool>community</codePool>
</Technooze_Customer>
</modules>
</config>
In Magento, If you are on category page than it's easy to get current category.
$_current_category=$this->getCurrentCategory();
or,
$_current_category = Mage::registry('current_category');
I needed Current Category on product info page and on the footer.phtml files. Because I had custom background set for each Category. So, Below code helped me to find the Current Category in my Magento's phtml file.
