Magento – subcategory listing in sidebar of category page

categorysidebar

I need to show subcategories in sidebar for currently opened category page.

e.g

CMS
  wordpress
    Art
    Auction
  joomla
  drupal

if i am on cms page it shows wordpress, joomla ,drupal in sidebar.
if i am on wordpress it shows art and auction.
but if i am on art page , left side is blank..in that case i want it to show
Wordpress (its parent)
and its subcategories.

Please suggest

EDIT

This is the code.

there is hierarchy of category, but for that last categoy in this case 'art'
has no subcategories in it.
So the sidebar comes out to be blank.

<!-- subcategory code -->

<?php

$category = Mage::getSingleton('catalog/layer')->getCurrentCategory();
$categories = $category->getCollection()
        ->addAttributeToSelect(array('name', 'thumbnail'))
        ->addAttributeToFilter('is_active', 1)
        ->addIdFilter($category->getChildren())
 ?>
 <div class="block">

 <div class="block-title">
    <span><?php echo $category->getName() ?></span>

    </div>
    <div class="block-content clearfix">
<ul class="subcategories">
    <?php foreach ($categories as $category): ?>
        <li>
            <a href="<?php echo $category->getUrl() ?>"><!--<img src="<?php echo Mage::getBaseUrl('media') . 'catalog' . DS . 'category' . DS . $category->getThumbnail() ?>" alt="<?php echo $this->htmlEscape($category->getName()) ?>" />-->
                <span><?php echo $category->getName() ?>
               <?php $collection = Mage::getModel('catalog/product')->getCollection()->addCategoryFilter($category);

echo "(".count($collection).")"; ?></span>
                </a>
        </li>
    <?php endforeach; ?>
</ul></div>
</div>
<!-- subcategory code -->

You can use the following code at the top :

$category = Mage::getSingleton('catalog/layer')->getCurrentCategory();
if(!$category->getChildren()){
 //$parentcat_id = $category->getParentCategory()->getId();
 //$category = Mage::getSingleton('catalog/category')->load($parentcat_id);
 $category = $category->getParentCategory();
}
$categories = $category->getCollection()
        ->addAttributeToSelect(array('name', 'thumbnail'))
        ->addAttributeToFilter('is_active', 1)
        ->addIdFilter($category->getChildren());

Display Parent Category Products on Subcategory Page in Magento

I think an optimal solution for this would entail that a product collection for a given subcategory includes products belonging to its parent category, if the subcategory is flagged to allow such behavior.

Essentially, it comes down to adding an additional category (parent) filter to the product collection when you're on category 1.675, so that products in both 1 and 1.675 show up on. Here are the steps.

Create a category yes/no attribute. Something like include_parent_products/"Include parent products on display?". Once added, go to the category manage page for 1.675 and flag it yes.

Rewrite Mage_Catalog_Model_Layer::getProductCollection to load a modified collection if setting in step 1 is true.

$displayParentProducts = $this->getCurrentCategory()->getIncludeParentProducts();
if ($displayParentProducts) {
    $collection = $this->getCurrentCategory()->getProductCollectionIncludingParents();
} else {
    $collection = $this->getCurrentCategory()->getProductCollection();
}

Rewrite/Create a new method Mage_Catalog_Model_Category::getProductCollectionIncludingParents.

public function getProductCollection()
{
    $parentCategory = ...; // Find parent category
    $collection = Mage::getResourceModel('catalog/product_collection')
        ->setStoreId($this->getStoreId())
        ->addCategoryFilter($this)
        ->addCategoryFilter($parentCategory)
        ;
    return $collection;
}

With the above completed, category 1.675 will now display its products and its parent's as well.

Magento – Show all store categories in sidebar on product listing page

Add the below code in your theme’s catalog XML file like this:

<reference name="left">
    <block type="catalog/navigation" name="catalog.leftnav" template="catalog/navigation/my_left_nav.phtml" />
</refrence>

It should be placed inside the reference name “left“, to show it in the left sidebar. I hope you know all these stuffs. Let’s get to the point. Just copy and paste the code in the my_left_nav.phtml, which should be in your theme’s catalog/navigation folder.

<!-- List all categories and their second level subcategories -->
<div class="block block-list block-categories">
    <div id="block-categories" class="block-title active">
        <strong><span>Categories </span></strong>
    </div>

<div id="leftnav" class="block-content" style="display:block">
    <?php $helper = $this->helper('catalog/category') ?>
    <?php $categories = $this->getStoreCategories() ?>
    <?php if (count($categories) > 0): ?>
        <ul id="leftnav-tree" class="level0">
            <?php foreach($categories as $category): ?>
                <li class="level0<?php if ($this->isCategoryActive($category)): ?> active<?php endif; ?>">
                    <a href="<?php echo $helper->getCategoryUrl($category) ?>"><span><?php echo $this->escapeHtml($category->getName()) ?></span></a>
                    <?php //if ($this->isCategoryActive($category)): ?>
                        <?php $subcategories = $category->getChildren() ?>
                        <?php if (count($subcategories) > 0): ?>
                            <ul id="leftnav-tree-<?php echo $category->getId() ?>" class="level1">

                                         <?php $secondLevelSubcategories = $subcategory->getChildren() ?>

                                <?php endforeach; ?>
