How to display list categories in wordpress integration magento

Question

Can help somebody. I spent several hours to find solution but without results I tried to display the list of categories on homepage wordpress blog thru following code

<?php $category = Mage::registry('wordpress_category') ?>
<?php if ($category): ?>
<?php echo $category->getId() ?>: <?php echo $category->getName() ?>
<?php endif; ?> 

But the method

Mage::registry('wordpress_category') 

always return null. I found that, i should probably be using the Fishpig_Wordpress_Block_Category_View. But i dont know where i should put it.

The following code will retrieve the current category when viewing a category page in your blog:

<?php Mage::registry('wordpress_category') ?>

This is not what you need. To view a list of categories, you could create a custom collection using the following:

<?php $categories = Mage::getResourceModel('wordpress/post_category_collection') ?>

A better way would be to use the category widget block:

<block type="wordpress/sidebar_widget_categories" name="wp.categories" template="wordpress/sidebar/widget/categories.phtml" />

You can create this in PHP using the following code:

<?php echo Mage::getSingleton('core/layout')
    ->createBlock('wordpress/sidebar_widget_categories')
    ->setTemplate('wordpress/sidebar/widget/categories.phtml')
    ->toHtml() ?>

The above code uses the default template, however, feel free to use your own custom template.
