How do I get the current catageory id?

Question

I have a CMS page that I am going to display products on with the following updated XML code:

<reference name="content">
    <block type="catalog/product_list"  name="product_list" template="catalog/product/wholesale-list.phtml">
        <action method="setCategoryId"><category_id>191</category_id></action>
        <action method="setToolbarBlockName"><name>product_list_toolbar</name></action>
    </block>
</reference> 

I have tried getting the ID I set in the layout, but no such luck. I have tried:

$_category = Mage::registry(‘current_category’);
$currentCategoryId= $_category->getId();

and

$layer = Mage::getSingleton(‘catalog/layer’);
$_category = $layer->getCurrentCategory();
$currentCategoryId= $_category->getId();

But neither of these methods work. Does anyone know how I can get the ID?

Answer 1

i think this is the best way ;)

Mage::registry('current_category')->getId();

Answer 2

Haven't tried this, but maybe something like:

$this->getLayout()->getBlock('product_list')->getCategoryId()

This way you are directly getting the variable that you have set on the Block object in the XML.

Try below code

 Mage::getModel('catalog/layer')->getCurrentCategory()->getId();
